Transdiagnostic Internet-delivered cognitive behaviour therapy in Canada: An open trial comparing results of a specialized online clinic and nonspecialized community clinics

A scoping review of therapist behaviors in guided digital mental health interventions

Guided digital mental health interventions are more effective than unguided interventions. While research often emphasizes the frequency and intensity of guidance, less attention has been paid to the behaviors enacted by the therapists supporting clients using these interventions. A scoping review of the literature was conducted to systematically examine the evidence on therapist behaviors (i.e., the actions and feedback provided by supporters to patients). Applying broad eligibility criteria, a systematic search was conducted in PubMed, PsycInfo, the Cochrane Library, and Embase from their inception to January 1st 2024. Sixteen studies met inclusion criteria and were included in the review. Following data extraction, a descriptive analysis and synthesis of the results was performed. Most studies (n = 12; 75 %) focused on therapist behaviors in the context of internet-delivered Cognitive Behavioral Therapy for anxiety and depression. While earlier studies primarily focused on identifying therapist behaviors, later studies shifted towards examining the associations between therapist behaviors and different outcomes, as well as deriving research and clinical applications for improving guided internet-delivered treatments. Identified gaps and recommendations for clinical practice, research, training, and treatment development are discussed.

Outcomes of transdiagnostic internet-delivered cognitive behavioural therapy tailored to public safety personnel: A longitudinal observational study

First responders and other public safety personnel (PSP) experience high rates of mental health problems and face barriers to accessing mental healthcare. Internet-delivered cognitive behavioural therapy (ICBT) is an effective and accessible treatment for various mental health concerns. Canadian PSP report favorable attitudes toward ICBT, and preliminary outcomes demonstrate that they benefit from it. Expanding on this research, the current study consisted of a longitudinal observational study of 560 Canadian PSP who participated in ICBT. It was designed to assess the longer term effectiveness of ICBT and moderators of outcomes by gender, linguistic and occupational group, and years of occupational experience. We evaluated symptom change at 8, 26, and 52 weeks post-enrollment, and results among PSP who had elevated clinical scores, showed large reductions (Hedges' g) in symptoms of depression (g = 1.3), anxiety (g =1.48), posttraumatic stress (g =1.24), panic (g =1.19), and anger (g =1.07) and moderate reductions in symptoms of social anxiety (g =.48-.56). Moderator analyses revealed modest differences in pre-treatment symptoms among certain groups but no group differences in symptom change over time. Clients showed good completion of treatment materials and reported high treatment satisfaction. The results suggest further study of ICBT tailored to PSP is warranted, including evaluating ICBT tailored for PSP in other countries.

Treating comorbid insomnia in patients enrolled in therapist-assisted transdiagnostic internet-delivered cognitive behaviour therapy for anxiety and depression: A randomized controlled trial

Transdiagnostic Internet-delivered cognitive behaviour therapy (ICBT) for patients experiencing anxiety and depression can produce large improvements in symptoms. Comorbid insomnia is common among individuals seeking treatment for anxiety and depression, yet transdiagnostic ICBT rarely targets insomnia and many ICBT patients report that symptoms of insomnia remain after treatment. This trial explored the impact of including a brief intervention for insomnia alongside an existing transdiagnostic ICBT course that included brief weekly therapist assistance. Patients were randomly assigned to receive either the Standard transdiagnostic (n = 75) or a Sleep-Enhanced course (n = 142), which included information on sleep restriction and stimulus control. Intent-to-treat analyses using generalized estimating equation (GEE) showed significant, large reductions in all primary outcomes (insomnia: d = 0.96, 95 % CI [0.68, 1.24]; depression: d = 1.04, 95 % CI [0.76, 1.33]; and anxiety: d = 1.23, 95 % CI [0.94, 1.52]) from pre-treatment to post-treatment, with changes maintained at 3-months. Patients assigned to the Sleep-Enhanced course reported larger reductions in insomnia than patients in the Standard transdiagnostic course (Cohen's d = 0.31, 95 % CI [0.034, 0.60]) at post-treatment but no significant between-group differences in any of the primary outcomes were found at follow-up. Patient-reported adherence to sleep restriction guidelines (p = .03), but not stimulus control instructions (p = .84) was associated with greater reductions in insomnia symptoms during the course. Overall, patients who received the Sleep-Enhanced course were satisfied with the materials and most patients reported making sleep behaviour changes. The trial results demonstrate that including a brief intervention targeting insomnia can be beneficial for many patients who enroll in ICBT primarily for symptoms related to anxiety and depression.

Acceptability and effectiveness study of therapist-assisted internet-delivered cognitive behaviour therapy for agriculture producers

Agriculture producers are less likely to seek or to receive mental health services compared to the general population. Additional research is needed to identify effective and accessible mental health interventions for this underserved population. This study used a mixed-methods approach and open trial design to examine the acceptability and effectiveness of therapist-assisted internet-delivered cognitive behaviour therapy (ICBT) supplemented with an additional agricultural resource for clients from agricultural backgrounds receiving ICBT in routine care. Clients (n = 34) participated in an online, five-lesson course that provided psychoeducation and strategies for dealing with symptoms of anxiety and depression, with weekly therapist assistance. Clients also received a tailored resource (developed with input from those with an agricultural background) providing culturally specific information and case stories pertinent to agricultural communities. Intent-to-treat analyses showed that the ICBT program was effective in reducing anxiety and depression symptoms among the agricultural population. Large within-group pre-to-post-treatment Cohen's effect sizes of d = 1.14, 95 % CI [0.41, 1.86] and d = 1.15, 95 % CI [0.42, 1.87] were found for depression and anxiety, respectively and comparable to the same program offered to the general population. Clients also experienced reductions in perceived stress and significant improvements in resiliency from pre- to post-treatment. Semi-structured interviews conducted at post-treatment with the agricultural clients (n = 31) on their experiences with ICBT identified four main themes: perceived strengths of ICBT and the tailored resource, suggestions to improve service delivery for agriculture producers, clients experienced internal and external challenges to participating in ICBT, and the positive impact of the course reached beyond the client. Very high satisfaction rates were found. These results provide support for the acceptability and effectiveness of ICBT with a tailored resource offered in routine care among agriculture producers.

Patient and Therapist Perceptions of a Publicly Funded Internet-Based Cognitive Behavioral Therapy (iCBT) Program for Ontario Adults During the COVID-19 Pandemic: Qualitative Study

BACKGROUND

To address the anticipated rise in mental health symptoms experienced at the population level during the COVID-19 pandemic, the Ontario government provided 2 therapist-assisted internet-delivered cognitive behavioral therapy (iCBT) programs to adults free of charge at the point of service.

OBJECTIVE

The study aims to explore the facilitators of and barriers to implementing iCBT at the population level in Ontario, Canada, from the perspective of patients and therapists to better understand how therapist-assisted iCBT programs can be effectively implemented at the population level and inform strategies for enhancing service delivery and integration into the health care system.

METHODS

Using a convenience sampling methodology, semistructured interviews were conducted with 10 therapists who delivered iCBT and 20 patients who received iCBT through either of the publicly funded programs to explore their perspectives of the program. Interview data were analyzed using inductive thematic analysis to generate themes.

RESULTS

Six salient themes were identified. Facilitators included the therapist-assisted nature of the program; the ease of registration and the lack of cost; and the feasibility of completing the psychoeducational modules given the online and self-paced nature of the program. Barriers included challenges with the online remote modality for developing the therapeutic alliance; the program's generalized nature, which limited customization to individual needs; and a lack of formal integration between the iCBT program and the health care system.

CONCLUSIONS

Although the program was generally well-received by patients and therapists due to its accessibility and feasibility, the digital format of the program presented both benefits and unique challenges. Strategies for improving the quality of service delivery include opportunities for synchronous communication between therapists and patients, options for increased customization, and the formal integration of iCBT into a broader stepped-care model that centralizes patient referrals between care providers and promotes continuity of care.

The Evaluation of the GET.ON Nationwide Web-Only Treatment Service for Depression- and Stress-Related Symptoms: Naturalistic Trial

BACKGROUND

GET.ON (HelloBetter) treatment interventions have been shown to be efficacious in multiple randomized controlled trials.

OBJECTIVE

This study evaluated the effectiveness of 2 GET.ON interventions, GET.ON Mood Enhancer and GET.ON Stress, in a national digital mental health service implemented across Germany.

METHODS

Following an initial web-based questionnaire, participants were allocated to either intervention based on their baseline symptom severity and personal choice and received a semistandardized guided, feedback-on-demand guided, or self-guided version of the treatment. Uncontrolled routine care data from 851 participants were analyzed using a pretest-posttest design. Half of the participants (461/851, 54.2%) were allocated to the stress intervention (189/461, 41% semistandardized; 240/461, 52% feedback on demand; and 32/461, 6.9% self-guided), and almost all participants in the mood intervention (349/352, 99.2%) received semistandardized guidance.

RESULTS

Results on depression-related symptom severity indicated a reduction in reported symptoms, with a large effect size of d=-0.92 (95% CI -1.21 to -0.63). Results on perceived stress and insomnia indicated a reduction in symptom severity, with large effect sizes of d=1.02 (95% CI -1.46 to -0.58) and d=-0.75 (95% CI -1.10 to -0.40), respectively. A small percentage of participants experienced deterioration in depression-related symptoms (11/289, 3.8%), perceived stress (6/296, 2%), and insomnia (5/252, 2%). After completing treatment, 51.9% (150/289) of participants showed a clinically reliable change in depression-related symptoms, whereas 20.4% (59/289) achieved a close to symptom-free status. Similar improvements were observed in perceived stress and insomnia severity. Guidance moderated the effectiveness of and adherence to the interventions in reducing depressive symptom severity. Effect sizes on depression-related symptom severity were d=-1.20 (95% CI -1.45 to -0.93) for the semistandardized group, d=-0.36 (95% CI -0.68 to -0.04) for the feedback-on-demand group, and d=-0.83 (95% CI -1.03 to -0.63) for the self-guided group. Furthermore, 47.6% (405/851) of the participants completed all modules of the intervention. Participant satisfaction was high across all patient groups and both interventions; 89.3% (242/271) of participants would recommend it to a friend in need of similar help. Limitations include the assignment to treatments and guidance formats based on symptom severity. Furthermore, part of the differences in symptom change between groups must be assumed to be due to this baseline difference in the measures.

CONCLUSIONS

Future digital health implementation and routine care research should focus on monitoring symptom deterioration and other negative effects, as well as possible predictors of deterioration and the investigation of individual patient trajectories. In conclusion, this study supports the effectiveness of tailored digital mental health services in routine care for depression- and stress-related symptoms in Germany. The results highlight the importance of guidance in delivering internet-based cognitive behavioral therapy interventions and provide further evidence for its potential delivered as web-only solutions for increasing access to and use of psychological treatments.

Web-Based Mindfulness Meditation as an Adjunct to Internet-Delivered Cognitive Behavioral Therapy for Public Safety Personnel: Mixed Methods Feasibility Evaluation Study

BACKGROUND

Public safety personnel (PSP) are individuals who work to ensure the safety and security of communities (eg, correctional workers, firefighters, paramedics, and police officers). PSP have a high risk of developing mental disorders and face unique barriers to traditional mental health treatments. The PSP Wellbeing Course is a transdiagnostic, internet-delivered cognitive behavioral therapy (iCBT) course tailored to assist PSP with symptoms of depression, anxiety, and posttraumatic stress disorder (PTSD). The initial course outcomes are promising, but some clients report some challenges with learning skills and recommend adding additional resources. Mindfulness meditations, which help people to experience the world and their reactions to the world in open and nonjudgmental ways, may complement the existing PSP Wellbeing Course.

OBJECTIVE

This study aims to examine the feasibility of mindfulness meditations in iCBT tailored for PSP. Information was gathered to evaluate engagement and client experiences with mindfulness meditations, symptom change, and the relationship between mindfulness meditation use and symptom change.

METHODS

A mixed methods study was conducted on PSP enrolled in the PSP Wellbeing Course who were offered 5 mindfulness meditations during the program (ie, 1/lesson). Clients completed questionnaires on depression, anxiety, PTSD, anger, insomnia, resilience, and mindfulness at pretreatment and at 8 weeks; an 8-week treatment satisfaction questionnaire; and brief weekly measures of mindfulness meditation engagement. We used paired sample t tests (2-tailed) to assess changes in outcomes over time and partial correlations to assess whether mindfulness meditation use predicted outcomes at posttreatment. A total of 12 clients were interviewed about their perceptions of the mindfulness meditations, and interviews were analyzed using directed content analysis.

RESULTS

Among the 40 clients enrolled, 27 (68%) reported using the mindfulness meditations, practicing for an average of 4.8 (SD 8.1) minutes each week. Most interviewees described the mindfulness meditations as beneficial but also reported challenges, such as discomfort while sitting with their feelings. Clients provided suggestions for better integration of mindfulness into iCBT. Overall, clients who completed the PSP Wellbeing Course with mindfulness meditations experienced statistically significant improvements in symptoms of anxiety (P=.001), depression (P=.001), PTSD (P=.001), and anger (P=.001) but not insomnia (P=.02). Clients also experienced improvements in resilience (P=.01) and mindfulness (P=.001). Self-reported time spent meditating was not associated with changes in symptoms over time.

CONCLUSIONS

This study provides new insight into the integration of mindfulness meditations with iCBT for PSP. It demonstrates the partial feasibility of adding mindfulness meditations to iCBT, revealing that some, but not all, PSP engaged with the meditations and reported benefits. PSP reported using the mindfulness meditations inconsistently and described challenges with the meditations. Improvements can be made to better integrate mindfulness meditation into iCBT, including offering mindfulness meditation as an optional resource, providing more psychoeducation on managing challenges, and offering shorter meditations.

Implementation of digital health interventions in rehabilitation: A scoping review

OBJECTIVE

Digital health interventions have potential to enhance rehabilitation services by increasing accessibility, affordability and scalability. However, implementation of digital interventions in rehabilitation is poorly understood. This scoping review aims to map current strategies, research designs, frameworks, outcomes and determinants used to support and evaluate the implementation of digital interventions in rehabilitation.

DATA SOURCES

Comprehensive searches from inception until October 2022 of MEDLINE, CINAHL, PsycINFO, PEDro, SpeechBITE, NeuroBITE, REHABDATA, WHO International Clinical Trial Registry and the Cochrane Library.

METHODS

Two reviewers screened studies against the eligibility criteria. Implementation science taxonomies and methods, including Powell et al.'s compilation of implementation strategies, were used to guide analysis and synthesis of findings.

RESULTS

The search retrieved 13,833 papers and 23 studies were included. Only 4 studies were randomised controlled trials and 9 studies (39%) were feasibility studies. Thirty-seven discrete implementation strategies were reported across studies. Strategies related to training and educating clinicians (91%), providing interactive assistance (61%), and developing stakeholder interrelationships (43%) were most frequently reported. Few studies adequately described implementation strategies and methods for selecting strategies. Almost all studies measured implementation outcomes and determinants; most commonly, acceptability, compatibility and dose delivered of digital interventions.

CONCLUSION

The rigour of implementation methods in the field is currently poor. Digital interventions require carefully planned and tailored implementation to facilitate successful adoption into rehabilitation practice. To keep pace with rapidly advancing technology, future rehabilitation research should prioritise using implementation science methods to explore and evaluate implementation while testing effectiveness of digital interventions.

Implementing Digital Cognitive-Behavioral Therapy for Major Depressive Disorder in Routine Psychiatric Appointments: A Pilot Project in a Rural Population

Psychotherapy is well-established as an effective treatment for major depressive disorder (MDD). However, many individuals with MDD in rural areas of the United States do not have access to psychotherapy. Self-management (SM) strategies are now the standard of care for chronic medical conditions and may be a viable alternative for individuals without access to psychotherapy. The current article describes the implementation of a 13-week pilot project to integrate digital cognitive-behavioral therapy (dCBT) SM programs into routine psychiatric advanced practice nurse (APN) telehealth appointments in the rural United States. Eight participants completed the project. The project did not meet the benchmark of 20 participants to improve access to treatment; however, one half (n = 4) of participants reported clinically significant improvement in MDD symptoms over 6 weeks. For clients without access to psychotherapy, dCBT SM programs can be effective in improving individual client outcomes when implemented by APNs in routine telehealth appointments.

Patient-Oriented Research to Improve Internet-Delivered Cognitive Behavioural Therapy for People of Diverse Ethnocultural Groups in Routine Practice

There has been limited research on improving Internet-delivered Cognitive Behavioural Therapy (ICBT) in routine online therapy clinics that serve people from diverse ethnocultural groups (PDEGs). This article describes a patient-oriented adaptation approach used to address this gap in research. A working group consisting of people with lived experience, community representatives, ICBT clinicians, managers, and researchers was formed. The working group examined archival feedback on ICBT from past patients who self-identified as being from diverse ethnocultural backgrounds (N = 278) and the results of interviews with current patients (N = 16), community representatives (N = 6), and clinicians (N = 3). The archival data and interviews revealed the majority of the patients reported being satisfied with and benefitting from ICBT. Suggestions for improvement were not related to the cognitive-behavioural model and techniques, but rather to making treatment materials more inclusive. Consequently, the ICBT adaptation focused on adding content related to cultural influences on mental health, addressing stigma, diversifying case stories, examples, and imagery, adding audiovisual introductions, and replacing English idioms with more descriptive language. Moreover, further training was offered to clinicians, and efforts were made to improve community outreach. This study demonstrates a process for using patient-oriented research to improve ICBT within routine care serving patients of diverse backgrounds.

Sustaining and Expanding Internet-Delivered Cognitive Behavioral Therapy (ICBT) for Public Safety Personnel across Canada: A Survey of Stakeholder Perspectives

Public safety personnel (PSP) experience an elevated risk of mental health problems and face barriers to treatment. Internet-delivered cognitive behavioral therapy (ICBT) has been tailored to PSP to improve access to mental health care. In this study, we sought to investigate perceptions of ICBT, particularly among those with and without prior knowledge of ICBT and between PSP leaders and non-leaders. A survey was administered to 524 PSP from across Canada to identify (a) how PSP perceive ICBT, (b) the extent of organizational support for tailored ICBT in PSP organizations, particularly leadership's support, and (c) perceived facilitators and barriers to funding tailored ICBT. The results indicated that PSP perceive ICBT to have more advantages than disadvantages. PSP who had previously heard of tailored ICBT had more positive perceptions. PSP indicated that there is a need for ICBT, and PSP leaders indicated their support for the implementation of tailored ICBT. The study identified that there is a need for increasing awareness of the effectiveness of and need for ICBT in order to facilitate funding of services. Overall, the current study indicates that PSP support ICBT as a valued form of therapy and that policy makers and service providers seeking to provide ICBT to PSP may increase support for ICBT services through more education and awareness.

Virtual Music Therapy versus Virtual Cognitive Behavioral Therapy for Anxiety in Cancer Survivors: Rationale and Protocol for a Comparative Effectiveness Trial (Preprint)

BACKGROUND

Cancer survivors represent one of the fastest growing populations in the United States. Unfortunately, nearly 1 in 3 survivors experience anxiety symptoms as a long-term consequence of cancer and its treatment. Characterized by restlessness, muscle tension, and worry, anxiety worsens the quality of life; impairs daily functioning; and is associated with poor sleep, depressed mood, and fatigue. Although pharmacological treatment options are available, polypharmacy has become a growing concern for cancer survivors. Music therapy (MT) and cognitive behavioral therapy (CBT) are evidence-based, nonpharmacological treatments that have demonstrated effectiveness in treating anxiety symptoms in cancer populations and can be adapted for remote delivery to increase access to mental health treatments. However, the comparative effectiveness of these 2 interventions delivered via telehealth is unknown.

OBJECTIVE

The aims of the Music Therapy Versus Cognitive Behavioral Therapy for Cancer-related Anxiety (MELODY) study are to determine the comparative effectiveness of telehealth-based MT versus telehealth-based CBT for anxiety and comorbid symptoms in cancer survivors and to identify patient-level factors associated with greater anxiety symptom reduction for MT and CBT.

METHODS

The MELODY study is a 2-arm, parallel-group randomized clinical trial that aims to compare the effectiveness of MT versus CBT for anxiety and comorbid symptoms. The trial will enroll 300 English- or Spanish-speaking survivors of any cancer type or stage who have experienced anxiety symptoms for at least 1 month. Participants will receive 7 weekly sessions of MT or CBT delivered remotely via Zoom (Zoom Video Communications, Inc) over 7 weeks. Validated instruments to assess anxiety (primary outcome), comorbid symptoms (fatigue, depression, insomnia, pain, and cognitive dysfunction), and health-related quality of life will be administered at baseline and at weeks 4, 8 (end of treatment), 16, and 26. Semistructured interviews will be conducted at week 8 with a subsample of 60 participants (30 per treatment arm) to understand individual experiences with the treatment sessions and their impact.

RESULTS

The first study participant was enrolled in February 2022. As of January 2023, 151 participants have been enrolled. The trial is expected to be completed by September 2024.

CONCLUSIONS

This study is the first and largest randomized clinical trial to compare the short- and long-term effectiveness of remotely delivered MT and CBT for anxiety in cancer survivors. Limitations include the lack of usual care or placebo control groups and the lack of formal diagnostic assessments for psychiatric disorders among trial participants. The study findings will help guide treatment decisions for 2 evidence-based, scalable, and accessible interventions to promote mental well-being during cancer survivorship.

The complex association of barriers and interest in internet-delivered cognitive behavior therapy for depression and anxiety: informing e-health policies through exploratory path analysis

BACKGROUND

Internet-delivered cognitive behavioral therapy (ICBT) provides critical remote access to mental health care to at-risk populations. However, to our knowledge, no investigation has been conducted to understand complex pathways through which barriers to care (i.e. structural, attitudinal and technological) correlate with patient interest in ICBT.

AIM

The objective of this study is to develop and test a pathway analysis framework using structural equation modeling to understand direct and mediating associations of barriers to care with interest in ICBT.

METHODS

This cross-sectional observational study was conducted among adult (>18 years) urban and rural residents (n = 200) in Saskatchewan, Canada. An online survey assessed interest in ICBT, barriers to ICBT, demographics, and depression and anxiety symptoms. Utilizing structural equation modeling, a path analysis framework was developed.

RESULTS

Path analysis results showed how associations between complex barriers and demographic variables correlate with interest in ICBT. For instance, the negative association of perceived financial concerns and life chaos on interest in ICBT was mediated by perceived access to care.

CONCLUSION

The findings identify specific barriers that could be addressed through targeted population health interventions to improve uptake of ICBT.

Transdiagnostic Internet-Delivered Cognitive Behavioral Therapy for Symptoms of Postpartum Anxiety and Depression: Feasibility Randomized Controlled Trial

Background

Postpartum depression (PPD) and postpartum anxiety (PPA) are often comorbid and are associated with significant personal and economic costs. Fewer than half of the mothers experiencing PPD or PPA symptoms receive face-to-face treatment, suggesting a need for alternative delivery formats such as internet-delivered cognitive behavioral therapy (ICBT).

Objective

This pilot study aimed to examine the impact of a therapist-assisted, transdiagnostic ICBT program on symptoms of PPD and PPA, as there is only one previous study on transdiagnostic ICBT with this population, which did not include therapist assistance.

Methods

Clients endorsing the symptoms of PPD or PPA (N=63) were randomized to an 8-week transdiagnostic ICBT course (Wellbeing Course for New Moms) or to treatment as usual (TAU). Clients completed measures of depression, anxiety, stress, postnatal bonding, and relationship satisfaction, as well as measures of treatment satisfaction and therapeutic alliance, before treatment, after treatment, and at the 1-month follow-up. Outcome measures were also completed at the 6-month follow-up for clients who completed the ICBT course.

Results

Both the ICBT and TAU groups experienced statistically significant improvements over time. The ICBT group experienced larger improvements after treatment and at the 1-month follow-up on more measures than the TAU group, with medium between-group Cohen d effects on primary outcome measures for anxiety (Cohen d=0.65, 95% CI 0.13-1.17), PPD (Cohen d=0.52, 95% CI 0.01-1.04), and depression (Cohen d=0.56, 95% CI 0.05-1.08), and on secondary outcome measures of overall distress (Cohen d=0.69, 95% CI 0.17-1.21), anxiety (Cohen d=0.59, 95% CI 0.07-1.11), and stress (Cohen d=0.76, 95% CI 0.23-1.28). Time-by-group interactions for proportional reductions between groups over time were only significant after treatment and at the 1-month follow-up for the primary anxiety measure (P=.006). This study was underpowered for detecting small or medium effects. Overall, clients perceived the treatment as credible, and 95% (21/22) of the clients were satisfied with the treatment content and therapist support.

Conclusions

Findings from this pilot study provide preliminary support for transdiagnostic ICBT in treating PPD and PPA symptoms to improve access to psychological treatments.

Cost-effectiveness of varying degrees and models of therapist-assisted transdiagnostic internet-delivered cognitive behaviour therapy: Evidence from a randomized controlled trial

In routine care, Internet-delivered Cognitive Behaviour Therapy (ICBT) is often delivered with therapist support via emails/phone calls, but the cost-effectiveness of varying amounts of therapist support or having therapists specialized in ICBT is not known. This study compared the cost-effectiveness of specialized therapists providing ICBT support once-weekly (1WS) versus providing support once-weekly supplemented with a one-business-day response to patient emails (1W/1BD-S). We further compared the cost-effectiveness of 1W support offered by therapists employed in a specialized clinic (1WS) versus community clinics where therapists primarily deliver face-to-face therapy (1WC). Patients were randomly allocated to groups: 1WS group (n = 216), 1W/1BD-S group (n = 233), and 1WC group (n = 226). At baseline, 12, 24 and 52-week follow-up, patients completed the Treatment Inventory of Costs in Patients with Psychiatric Disorders questionnaire (TiC-P) adapted for use in Canada to assess healthcare use and productivity losses. Additionally, to assess Quality Adjusted Life Years (QALYs) gained, patients completed the EQ-5D-5L at the same time periods. We quantified uncertainties by one-way and probabilistic sensitivity analysis and reported Incremental cost-effectiveness ratios (ICER), cost-effectiveness planes and acceptability curves. Cost-effectiveness over 52 weeks was CAD 3072/QALY for 1WC, CAD 3244/QALY for 1W/1BD-S, and CAD 3528/QALY for 1WS. Our model suggests that 1WS is the best strategy since the incremental cost per QALY is below the $50,000 threshold (ICER is CAD 42,328/QALY compared to the next most effective, 1WC). 1W/1BD-S is dominated by the other strategies. The cost-effectiveness acceptability curves suggest that the 1WS group has a higher probability for cost-effectiveness (38 %) than 1W/1BD-S (30 %) and 1WC (32 %) when the willingness to pay is $50,000 per QALY. These results have important implications for health policymakers deciding on delivery of ICBT for the treatment of anxiety and/depressive disorders.

Efficacy of a transdiagnostic guided internet-delivered intervention for emotional, trauma and stress-related disorders in Mexican population: study protocol for a randomized controlled trial

BACKGROUND

Emotional and stress-related disorders show high incidence, prevalence, morbidity, and comorbidity rates in Mexico. In recent decades, research findings indicate that cognitive behavioral interventions, from a disorder-specific perspective, are the effective front-line treatment for anxiety and depression care. However, these treatments are not often used. Reasons include limited access and low availability to effective interventions and comorbidity between mental disorders. Emotional deregulation of negative affectivity has been found to be a mediating factor in addressing emotional disorders from a transdiagnostic perspective, aimed at two or more specific disorders. In addition, technological advancement has created alternatives for psychological assistance, highlighting the possibilities offered by technologies since Internet-supported intervention programs have been empirically tested for effectiveness, efficiency and efficacy and can be key to ensuring access to those who are inaccessible. The aim of the study is to evaluate the efficacy, moderators of clinical change and acceptability of a transdiagnostic guided Internet-delivered intervention versus a transdiagnostic self-guided Internet-delivered intervention for emotional, trauma and stress-related disorders, and waiting list in community sample.

METHODS

A three-armed, parallel group, superiority randomized controlled clinical trial with repeated measurements at four times: pretest, posttest, follow-up at 3, 6 and 12 months. Outcomes assessor, participant, care provider and investigator will be blinded. Participants aged 18 to 70 years will be randomly allocated 1:1:1 to one of three study arms: a) Transdiagnostic guided internet-delivered intervention with synchronous assistance, b) Transdiagnostic self-guided internet-delivered intervention, c) Waiting list group. Based on sample size estimation, a minimum of 207 participants (69 in each intervention group) will be included.

DISCUSSION

The study could contribute to improving the efficacy of transdiagnostic internet-delivered interventions to promote the dissemination of evidence-based treatments and eventually, to decrease the high prevalence of emotional and trauma-related disorders in the Mexican population.

Examining the Utility of a Sleep Resource in Transdiagnostic Internet-Delivered Cognitive Behavior Therapy: An Observational Study

Patients seeking transdiagnostic internet-delivered cognitive behavior therapy (T-ICBT) for anxiety or depression often have sleep difficulties. A brief resource that includes sleep psychoeducation and strategies for improving sleep (e.g., stimulus control and sleep restriction) may address comorbid insomnia without the need for an insomnia-specific ICBT course. This observational study explored patient use and feedback of a brief sleep resource available to all patients (n = 763) enrolled in an 8-week T-ICBT course. Overall, 30.1% of patients (n = 230) reviewed the resource and were older, more engaged with the ICBT course (i.e., more likely to complete the program, more logins, and greater number of days enrolled in the course) and had higher pretreatment insomnia symptoms than those who did not review the resource. Resource reviewers did not report larger improvements in symptoms of insomnia than non-reviewers, even among patients with clinical levels of insomnia, and average insomnia levels remained above the clinical cutoff at posttreatment. While patients were satisfied with the resource and it was beneficial to some patients, more research is needed to further explore how it may be integrated into T-ICBT and how therapists can encourage the use of the resource among patients who may benefit from the resource.

A Randomized Factorial Trial of Internet-Delivered Cognitive Behaviour Therapy for Post-Secondary Students: Examining Motivational Interviewing and Booster Lessons (Preprint)

Background

Internet-delivered cognitive behavioral therapy (ICBT) can improve access to mental health care for students, although high attrition rates are concerning and little is known about long-term outcomes. Motivational interviewing (MI) exercises and booster lessons can improve engagement and outcomes in face-to-face cognitive behavioral therapy.

Objective

This study aimed to examine the use of pretreatment MI exercises and booster lessons in ICBT for postsecondary students.

Methods

In this factorial trial (factor 1: web-based MI before treatment; factor 2: self-guided booster lesson 1 month after treatment), 308 clients were randomized to 1 of 4 treatment conditions, with 277 (89.9%) clients starting treatment. All clients received a 5-week transdiagnostic ICBT course (the UniWellbeing course). Primary outcomes included changes in depression, anxiety, and perceived academic functioning from before treatment to after treatment and at the 1-month and 3-month follow-ups.

Results

Overall, 54% (150/277) of students completed treatment and reported large improvements in symptoms of depression and anxiety and small improvements in academic functioning after treatment, which were maintained at the 1-month and 3-month follow-ups. Pretreatment MI did not contribute to better treatment completion or engagement, although small between-group effects favored MI for reductions in depression (Cohen d=0.23) and anxiety (Cohen d=0.25) after treatment. Only 30.9% (43/139) of students randomized to one of the booster conditions accessed the booster. Overall, no main effects were found for the booster. Subanalyses revealed that clients who accessed the booster had larger decreases in depressive symptoms (Cohen d=0.31) at the 3-month follow-up. No interactions were found between MI and the booster.

Conclusions

Rather than offering MI before treatment, clients may experience more benefits from MI exercises later in ICBT when motivation wanes. The low uptake of the self-guided booster limited our conclusions regarding its effectiveness. Future research should examine offering a booster for a longer duration after treatment, with therapist support and a longer follow-up period.

Conceptual Invariance, Trajectories, and Outcome Associations of Working Alliance in Unguided and Guided Internet-Based Psychological Interventions: Secondary Analysis of a Randomized Controlled Trial

BACKGROUND

The role of working alliance remains unclear for many forms of internet-based interventions (IBIs), a set of effective psychotherapy alternatives that do not require synchronous interactions between patients and therapists.

OBJECTIVE

This study examined the conceptual invariance, trajectories, and outcome associations of working alliance across an unguided IBI and guided IBIs that incorporated clinician support through asynchronous text messaging or video messaging.

METHODS

Adults with high education attainment (n=145) with subclinical levels of anxiety, stress, or depressive symptoms were randomized to 1 of 3 treatment conditions for 7 weeks. All participants received treatments from MyCompass, an unguided IBI using cognitive behavior therapy. Participants in condition 2 and 3 received supplemental, asynchronous clinician support through text and video, respectively. Working alliance with the IBIs was measured weekly using select items from the 12-item version of the Agnew Relationship Measure. Symptom and functional outcomes were assessed at baseline, at the end of treatment, and 1-month follow-up.

RESULTS

Working alliance with the IBIs was conceptually invariant across the 3 conditions. Working alliance followed a quadratic pattern of change over time for all conditions and declined significantly only in the text-support condition. After controlling for baseline symptoms, higher baseline levels of working alliance predicted less depression and less functional impairment at follow-up, whereas faster increases in working alliance predicted less worry at the end of treatment and at follow-up, all of which only occurred in the video-support condition.

CONCLUSIONS

Working alliance with the IBIs was generally established in the initial sessions. Although working alliance is conceptually invariant across IBIs with or without clinician support, the associations between working alliance and treatment outcomes among IBIs may differ depending on clinician involvement and the modalities of support.

Understanding and Addressing Occupational Stressors in Internet-Delivered Therapy for Public Safety Personnel: A Qualitative Analysis

Internet-delivered cognitive behavioral therapy (ICBT) is effective when tailored to meet the needs of public safety personnel (PSP). Nevertheless, there is limited research on the nature of the occupational stressors faced by PSP who seek ICBT and how PSP use ICBT to address occupational stressors. We provided tailored ICBT to PSP (N = 126; 54% women) and conducted a qualitative content analysis on clinicians’ eligibility screening notes, clients’ emails, and clients’ survey responses to understand the occupational stressors faced by PSP and their use of ICBT to address such stressors. Clients described several occupational stressors, including operational stressors (e.g., potentially psychologically traumatic events and sleep/shiftwork issues) and organizational stressors (e.g., issues with leadership, resources, and workload). More clients shared occupational concerns during the screening process (97%) than during treatment (58%). The most frequently cited occupational stressor was exposure to potentially psychologically traumatic events. Clients reported using course skills (e.g., controlled breathing and graduated exposure) to manage occupational stressors (e.g., responding to calls, workplace conflict, and work–family conflict). Thought challenging was the most frequently reported strategy used to manage occupational stressors. The current results provide insights into the occupational stressors PSP experience and endeavor to manage using ICBT, which can inform further efforts to tailor ICBT for PSP (e.g., adapting course materials and examples to take into account these operational and occupational stressors).

Lessons learned from two feasibility trials of a translated and minimally monitored iCBT program for young adults among community and university samples

Young adults are less likely to use traditional mental health services than adults. iCBT may be more youth friendly, but its access remains limited in several countries. This study aims to evaluate the feasibility of a minimally monitored transdiagnostic iCBT program translated from English to French and offered in Canada for the treatment of anxiety and depression among young adults. The impact of the program on resilience was also assessed. Twenty-five participants from community and university samples were included in the analyses in two separate single-group feasibility trials with a 3-month follow-up. Feasibility outcomes were attrition, adherence, treatment acceptability and treatment gains. Outcome measures included the Patient Health Questionnaire 9-item (PHQ-9), Generalized Anxiety Disorder 7-item (GAD-7) and Connor-Davidson Resilience Scale (CD-RISC). In Trial 1 (N = 10), recruiting among the general population proved to be challenging. Low adherence (20%) and high attrition (80%) rates were observed. Methodological changes to recruitment were made and a second trial was conducted among university students using incentives (N = 15). About half of the participants completed treatment (55%, n = 8/15), 12/15 provided post-treatment data and 8/15 provided 3-month follow-up data. All study completers (100%; n = 14) reported they would recommend the program. Mixed effects model analyses revealed significant and large pre-post treatment reductions on the PHQ-9 and GAD-7 (Cohen's d = 1.09 and 1.64 respectively) with treatment gains maintained at follow-up. Moderate improvements were found on the CD-RISC post-treatment with further gains at follow-up (ds = 0.55 and 1.10 respectively). These finding suggest that future research on this French-Canadian version of the Mood Mechanic Course is feasible with appropriate attention to recruitment. Translating existing iCBT interventions and using minimal monitoring may be an optimal first step to initiate the cross-cultural dissemination of iCBT while increasing access to treatments among young adults. Lessons learned are discussed.

Utilization, Patient Characteristics, and Longitudinal Improvements among Patients from a Provincially Funded Transdiagnostic Internet-delivered Cognitive Behavioural Therapy Program: Observational Study of Trends over 6 Years

OBJECTIVE

There is strong evidence supporting internet-delivered cognitive behaviour therapy (iCBT) and consequently growing demand for iCBT in Canada. Transdiagnostic iCBT that addresses both depression and anxiety is particularly promising as it represents an efficient method of delivering iCBT in routine care. The Online Therapy Unit, funded by the Saskatchewan government, has been offering transdiagnostic iCBT for depression and anxiety since 2013. In this article, to broadly inform implementation efforts, we examined trends in utilization, patient characteristics, and longitudinal improvements for patients receiving transdiagnostic iCBT over 6 years.

METHODS

Patients who completed telephone screening between November 2013 and December 2019 were included in this observational study. Patients provided demographics and mental health history at screening and completed measures at pre-treatment, post-treatment and at 3- to 4-month follow-up. Treatment engagement and satisfaction were assessed.

RESULTS

A total of 5,321 telephone screenings were completed and 4,283 of patients were accepted for treatment over the 6-year period (80.5% acceptance). The most common reason for referral to another service was high suicide risk/severe symptoms (47.1%). Examination of trends showed growing use of transdiagnostic iCBT over time (37% increase per year). There was remarkable stability in patient characteristics across years. Most patients were concurrently using medication (57.3%) with 11.9% reporting using iCBT while on a waiting list for face-to-face treatment highlighting the importance of integrating iCBT with other services. Consistent across years, large improvements in depression and anxiety symptoms were found and maintained at 3- to 4-month follow-up. There was strong patient engagement with iCBT and positive ratings of treatment experiences.

CONCLUSIONS

As there is growing interest in iCBT in Canada, this large observational study provides valuable information for those implementing iCBT in terms of likely user characteristics, patterns of use, and improvements. This information has potential to assist with resource allocation and planning in Canada and elsewhere.

A randomized factorial trial of internet-delivered cognitive behavioural therapy: An 8-week program with or without extended support and booster lesson

While internet-delivered cognitive behavioural therapy (ICBT) is effective, some patients suggest extended support post-treatment could improve care. In this randomized factorial trial, we examined the benefits of an 8-week therapist-assisted ICBT program offered with or without an optional 4-week extension of support (Factor 1) and with or without an optional booster lesson (Factor 2). Patients screened for ICBT for depression and/or anxiety were randomly assigned to the conditions (N = 434) and we examined the use of the extension and booster, differences between those who did or did not use extension or booster, and the impact of the extension or booster on outcomes, engagement, and satisfaction at 26-weeks post-enrollment. Therapists recorded time and observations with offering support during the extension and booster. In the extension group, 54.4% (n = 56) requested the extension, while in the booster group 50.9% (n = 56) accessed the booster, and in the combined group, 41.6% (n = 47) requested the extension and 51.3% (n = 58) accessed the booster. Those who requested the extension were older, and more likely to report medication and mental health service use and severe mental health-related disability at pre-treatment; they also reported putting less effort into ICBT and finding skills more difficult. The booster was more often used among those with lower symptom severity, and those who put more effort into and had more positive experiences with ICBT. As expected, those assigned to extension sent more messages to their therapist, and those assigned to booster logged in more often. Therapists also took more time to deliver ICBT with an extension (>18 min) or booster (>13 min) compared to the 8-week program, and perceived extension and booster as beneficial for some, but not all patients. Treatment satisfaction was high across conditions, and effect sizes were large from pre-treatment to 26-week follow-up on most measures. No significant group differences were found in this study. Lack of group differences, however, could reflect low use of the extension and booster. Results provide helpful information about the demand for extensions and boosters, and provide directions for future research.

Insights into internet-delivered cognitive behavioural therapy for public safety personnel: Exploration of client experiences during and after treatment

Canadian public safety personnel (PSP) experience high rates of mental health problems and barriers to receiving care. Internet-delivered cognitive behavioural therapy (ICBT) may help reduce barriers to care; however, there is no literature involving qualitative analyses of client feedback to describe PSP experiences with ICBT. Identifying these experiences is important because it can inform future use of ICBT with this group that has unique needs. The current study was designed to explore how clients (N = 82) experienced ICBT that had been tailored to meet their needs; specifically, the study assessed their perceptions of program impacts, what clients found helpful, and client suggestions for improvements. The ICBT course included five core lessons, client stories, and nine initial additional resources, as well as flexible frequencies (optional, once weekly, or twice weekly) and durations (8 to 16 weeks) of therapist support. A qualitative reliability thematic analysis was used to analyze client communications and feedback. Responses to a Treatment Satisfaction Questionnaire administered at eight weeks post-enrollment were available for 57 clients. Client emails with therapists were also examined among all clients, including an additional 25 clients who did not complete the Treatment Satisfaction Questionnaire. Themes identified in the qualitative analyses were related to: reported impacts and hindering events, helpful and challenging course skills and content, helpful aspects of the course, and areas for improvement. Clients who completed the Treatment Satisfaction Questionnaire and those who did not reported beneficial impacts from the program, with the most commonly endorsed themes being skill development and normalizing mental health issues. Hindering events were experienced by both groups and included timeline challenges, technology challenges, and negative effects. Comments from both groups suggested that clients had more success than challenges when practicing the skills. Thought challenging was the skill most frequently identified as helpful. Clients described many aspects of the program as helpful with the most frequently endorsed themes being the course format and content, the flexible nature of the course, access to additional materials and case stories, and therapist assistance. Clients also provided suggestions for improving the course (e.g., case stories, additional resources, timelines audio and videos). Overall, client communications suggest that ICBT is accepted and perceived as beneficial among PSP. These results informed rapid improvements to the ICBT program tailored for PSP and may inform others seeking to provide digital mental health services to PSP.

Brief online motivational interviewing pre-treatment intervention for enhancing internet-delivered cognitive behaviour therapy: A randomized controlled trial

While the efficacy of therapist-guided internet-delivered cognitive behaviour therapy (iCBT) for anxiety and depression is well-established, a significant proportion of clients show little to no improvement with this approach. Given that motivational interviewing (MI) is found to enhance face-to-face treatment of anxiety, the current trial examined potential benefits of a brief online MI intervention prior to therapist-guided iCBT. Clients applying to transdiagnostic therapist-guided iCBT in routine care were randomly assigned to receive iCBT with (n = 231) or without (n = 249) the online MI pre-treatment. Clients rated motivation at screening and pre-iCBT and anxiety and depression at pre- and post-treatment and at 13- and 25-week follow-up after enrollment. Clients in the MI plus iCBT group made more motivational statements in their emails and were enrolled in the course for a greater number of days compared to clients who received iCBT only, but did not demonstrate higher motivation after completing the MI intervention or have higher course completion. Clients in both groups, at screening and pre-iCBT, reported high levels of motivation. No statistically significant group differences were found in the rate of primary symptom change over time, with both groups reporting large reductions in anxiety and depression pre- to post-treatment (Hedges' g range = 0.96-1.11). During follow-up, clients in the iCBT only group reported additional small reductions in anxiety, whereas clients in the MI plus iCBT group did not. The MI plus iCBT group also showed small increases in depression during follow-up, whereas improvement was sustained for the iCBT only group. It is concluded that online MI does not appear to enhance client outcomes when motivation at pre-treatment is high.

Cultural adaptation of the Smiling is Fun program for the treatment of depression in the Ecuadorian public health care system: A study protocol for a randomized controlled trial

BACKGROUND

Depression is one of the world's major health problems. Due to its high prevalence, it constitutes the first cause of disability among the Americas, where only a very low percentage of the population receives the adequate evidence-based psychological treatment. Internet-Based Interventions (IBIs) are a great alternative to reduce the treatment gap for mental disorders. Although there are several studies in low-and middle-income countries proving IBIs' feasibility and acceptability, there is still little evidence of the effectiveness in diverse social and cultural contexts such as Latin America.

METHODS

Two studies will be described: Study 1 is focused on the cultural adaptation of a cognitive-behavioral IBI Smiling is Fun (Botella et al. 2012, 2015) for Ecuadorian population with depression based on the procedure by Salamanca-Sanabria et al. (2018). Study 2 describes the design of a randomized controlled trial to test the preliminary efficacy of the culturally adapted intervention in a Public Health Care setting. A total of 153 patients with mild to moderate degree of depression as assessed with the Mini-International Neuropsychiatric Interview (M.I.N.I.) and the Patient Health Questionnaire-9 (PHQ-9) will be randomly assigned to either an IBI group using only automated support by the system; an IBI group including also minimal human support; or a waiting list group. The primary outcome (depression) and secondary outcomes (e.g., anxiety, affect, quality of life) will be collected at baseline, 3, 6 and 12 months. Mixed-model analyses with no ad hoc imputations will be conducted.

DISCUSSION

This paper is pioneering in exploring the role of an Internet-based culturally adapted intervention for depression in a public care context in Ecuador. Results obtained will offer new insights into the viability and effectiveness of digital technologies for the psychological treatment of mental illnesses in developing countries.

A pragmatic factorial randomized controlled trial of transdiagnostic internet-delivered cognitive behavioural therapy: Exploring benefits of homework reflection questionnaires and twice-weekly therapist support

With the growing demand for internet-delivered cognitive behavioural therapy (iCBT), this pragmatic factorial (2 × 2 × 2) randomized controlled trial evaluated strategies for facilitating iCBT engagement and outcomes in routine care. Specifically, the benefits to patients and therapists of using homework reflection questionnaires and offering patients twice-weekly therapist support were examined. Patients (n = 632) accepted into iCBT for depression and/or anxiety were randomly assigned to complete homework reflection questionnaires or not (factor 1), receive once- or twice-weekly support (factor 2), and to receive care from therapists employed in one of two settings (iCBT clinic or a community mental health clinic; factor 3). Outcomes were measured at pre-treatment, and 8, 12, and 24-weeks post-enrollment. Therapist time was tracked and a focus group was conducted to examine therapist experiences. No differences in patient outcomes were found between therapists employed in the two settings; as such, these two groups were combined for further analyses. In terms of engagement, homework reflection questionnaires were associated with fewer website log-ins and days accessing iCBT; twice-weekly support was associated with more patient emails sent to therapists. Despite engagement differences, homework reflection questionnaires and twice-weekly support did not significantly impact primary outcomes; all groups showed large improvements in depression and anxiety that were maintained at 24-week follow-up. Therapists perceived a number of benefits and challenges associated with responding to homework reflection questionnaires and offering twice-weekly support; most notably the strategies did not benefit all patients. Twice-weekly support was associated with increased therapist time and organizational challenges. It is concluded that neither completion of homework questionnaires nor offering twice-weekly support significantly improve iCBT in routine care.

Understanding Problems With Sleep, Sexual Functioning, Energy, and Appetite Among Patients Who Access Transdiagnostic Internet-Delivered Cognitive Behavioral Therapy for Anxiety and Depression: Qualitative Exploratory Study

Background

Transdiagnostic internet-delivered cognitive behavioral therapy (T-ICBT) is an effective treatment for anxiety and depression, and nowadays, there is interest in exploring ways to optimize T-ICBT in routine care. T-ICBT programs are designed to address the primary cognitive-affective and behavioral symptoms of anxiety and depression (eg, low mood, worry, anhedonia, and avoidance). Treatment also has the potential to resolve other symptom concerns (eg, sleep disruption, sexual dysfunction, lack of energy, and appetite or weight changes). Having additional information regarding the extent of these concerns and how concerns change over time could prove beneficial for further development of T-ICBT in routine care.

Objective

This exploratory formative study aims to better understand sleep, sexual functioning, energy, and appetite concerns among T-ICBT clients seeking treatment for depression and anxiety. A qualitative analytic approach was used to identify themes in the symptom concerns reported by patients in the areas of sleep, sexual functioning, energy, and appetite at the time of enrollment. Patient responses to related items from screening measures for anxiety and depression were also examined pre- and posttreatment.

Methods

Patients in routine care who applied for a T-ICBT program for depression and anxiety over a 1-year period were included in this study. As part of the application and screening process, participants completed depression and anxiety symptom measures (ie, 9-item Patient Health Questionnaire and 7-item Generalized Anxiety Disorder scale). These same measures were administered posttreatment. Subsequently, they were asked if they were experiencing any problems with sleep, sexual activity, energy, or appetite (yes or no). If their response was yes, they were presented with an open-ended comment box that asked them to describe the problems they had experienced in those areas.

Results

A total of 462 patients were admitted to T-ICBT during the study period, of which 438 endorsed having some problems with sleep, sexual activity, energy, or appetite. The analysis of open-ended responses indicated that 73.4% (339/462) of patients reported sleep problems (eg, difficulty initiating or maintaining sleep), 69.3% (320/462) of patients reported problems with energy or motivation (eg, tiredness and low motivation), 57.4% (265/462) of patients reported appetite or body weight concerns (eg, changes in appetite and weight loss or gain), and 30.1% (139/462) of patients described concerns with sexual functioning (eg, loss of interest in sex and difficulty with arousal). Item analysis of symptom measures demonstrated that T-ICBT produced improvements in sleep, energy, and appetite in 8 weeks. Sexual dysfunction and weight changes were not represented in the screening measures, so it remains unclear what effect T-ICBT has on these symptoms.

Conclusions

Sleep disruption, lack of energy, appetite or weight changes, and sexual dysfunction are common concerns reported by clients enrolled in T-ICBT in routine practice and may deserve greater attention in T-ICBT program development and administration.

Effects of Internet-Based Cognitive Behavioral Therapy in Routine Care for Adults in Treatment for Depression and Anxiety: Systematic Review and Meta-Analysis

BACKGROUND

Although there is evidence for the efficacy of internet-based cognitive behavioral therapy (iCBT), the generalizability of results to routine care is limited.

OBJECTIVE

This study systematically reviews effectiveness studies of guided iCBT interventions for the treatment of depression or anxiety.

METHODS

The acceptability (uptake, participants' characteristics, adherence, and satisfaction), effectiveness, and negative effects (deterioration) of nonrandomized pre-post designs conducted under routine care conditions were synthesized using systematic review and meta-analytic approaches.

RESULTS

A total of 19 studies including 30 groups were included in the analysis. Despite high heterogeneity, individual effect sizes of investigated studies indicate clinically relevant changes, with effect sizes ranging from Hedges' g=0.42-1.88, with a pooled effect of 1.78 for depression and 0.94 for anxiety studies. Uptake, participants' characteristics, adherence, and satisfaction indicate a moderate to high acceptability of the interventions. The average deterioration across studies was 2.9%.

CONCLUSIONS

This study provides evidence supporting the acceptability and effectiveness of guided iCBT for the treatment of depression and anxiety in routine care. Given the high heterogeneity between interventions and contexts, health care providers should select interventions that have been proven in randomized controlled clinical trials. The successful application of iCBT may be an effective way of increasing health care in multiple contexts.

Transdiagnostic Internet-delivered cognitive behaviour therapy with therapist support offered once-weekly or once-weekly supplemented with therapist support within one-business-day: Pragmatic randomized controlled trial

In routine care, internet-delivered cognitive behaviour therapy (iCBT) regularly includes therapist support delivered via secure email, but the optimal response time to emails is unknown. In this study, we compared the benefits of therapists providing support once-weekly versus therapists providing support once-weekly supplemented with a one-business-day response to all patient emails. This pragmatic randomized controlled trial included therapists employed by a specialized iCBT clinic or community mental health clinics, where providing iCBT is a secondary service. Patients with depression and/or anxiety who enrolled in transdiagnostic iCBT (5 core lessons over 8 weeks) were randomized to: 1) once-weekly support supplemented with a one-business-day response to patient emails by specialized therapists (n = 233); 2) once-weekly support also offered by specialized therapists (n = 216); or 3) once-weekly support offered by community clinic therapists (n = 226). Outcomes were measured at 8, 12, 24, and 52-weeks post-enrollment. Patient engagement and treatment experiences (e.g., treatment satisfaction, therapist alliance) were also assessed and a focus group was conducted with therapists. Supplementing once-weekly therapist support with a one-business-day response to patient emails resulted in therapists sending more emails to patients (M: 13 versus 9) and required more therapist time over treatment (M: 155 versus 109 min), but was not associated with improved outcomes, patient engagement or treatment experiences. All groups showed large improvements in symptoms of depression and anxiety maintained at 52-week follow-up, strong engagement and positive treatment experiences. Therapists viewed challenges of responding to patient emails within one-business-day to outweigh benefits. Contrary to expectations, supplementing once-weekly therapist support with a one-business-day response to all patient emails did not benefit patients and increased therapist time as well as therapist challenges when delivering iCBT in routine care.

Exploring Perceptions of Internet-Delivered Cognitive Behaviour Therapy among Public Safety Personnel: Informing Dissemination Efforts

Background Public safety personnel (PSP) experience high rates of mental health disorders but have limited access to treatment. To improve treatment access, there is a growing interest in offering internet-delivered cognitive behaviour therapy (ICBT) to PSP. As attitudes towards ICBT can both impact and inform ICBT implementation efforts, this study examines perceptions of ICBT among PSP who viewed a poster (a commonly used method of advertising ICBT) or a poster supplemented with a story of a PSP who benefitted from ICBT. Methods Participants (N = 132) from various PSP sectors were randomly assigned to view a poster or a poster and a story. Participants then completed an online survey assessing their perceptions of ICBT using both qualitative and quantitative questions. We used a mixed-methods approach to analyze the data. Results No differences in perceptions of ICBT were identified between the conditions. Ratings of credibility, treatment expectancy, anticipated treatment adherence, and acceptability suggested that PSP had positive perceptions of ICBT. Most participants (93%) reported that they would access ICBT if they needed help with mental health concerns. Participants ranked therapist-guided ICBT as their second most preferred treatment, with psychologists ranked first. Female participants found ICBT more credible than male participants. More experienced PSP reported lower acceptability and anticipated adherence to ICBT. Conclusions The findings suggest that many PSP are likely to be receptive to ICBT even when a simple poster is used as a method of informing PSP of this treatment option. Further attention to improving the perceptions of ICBT among certain groups may be warranted.

Efficacy of internet-delivered cognitive behavioural therapy following an acute coronary event: A randomized controlled trial

Depression and anxiety are common among people who have experienced an acute coronary event (e.g., heart attack). Multidisciplinary cardiac rehabilitation programs often focus on reducing risk factors associated with future cardiac events, however, mental health interventions are not routinely available. Given known difficulties with access to mental health treatment, the present study sought to explore the efficacy and acceptability of an Internet-delivered cognitive behavioural therapy program (Cardiac Wellbeing Course) among participants who experienced an acute coronary event. The five-lesson course was delivered over eight weeks and was provided with brief weekly contact, via telephone and secure email with a guide. Participants were randomized to the Cardiac Wellbeing Course (n = 25) or waiting-list control group (n = 28). Symptoms were assessed at pre-treatment, post-treatment, and four-week follow-up. Completion rates (84%) and satisfaction ratings (95%) were high. Statistically significant between-group improvements were observed for the treatment group on primary measures of general anxiety (Cohen's d = 1.62; 67% reduction), depression (Cohen's d = 1.09; 61% reduction), and physical activity levels (Cohen's d = 0.27; 70% increase). Statistically significant improvements were also observed on secondary measures of distress (Cohen's d = 0.98; 51% reduction), cardiac anxiety (Cohen's d = 0.92; 34% reduction), and mental-health quality of life (Cohen's d = 0.23; 24% improvement). The changes were maintained at four-week follow-up. The current findings add to the existing literature and highlight the potential of Internet-delivered cognitive behavioural therapy programs among participants who have experienced an acute coronary event.

Audit and feedback of therapist-assisted internet-delivered cognitive behaviour therapy within routine care: A quality improvement case study

With the growing use of ICBT in routine care clinics there is a need for literature on how to monitor and improve the quality of therapist behaviours in clinical practice. In this paper, we first provide background literature on Audit and Feedback (A&F), a common quality improvement technique, and then present a case study regarding the use of A&F to improve quality of therapist behaviours in emails sent to patients provided with ICBT in routine care. The A&F measure used was derived from previous research on therapist's email behaviours in ICBT. Fifteen undesirable therapist behaviours (e.g., Did Not Message, Unresponsive to Symptom Increase, Does Not Address Patient Concern) were audited in 1840 emails sent from eight therapists to 198 randomly selected patients, representing 18% of 1114 patients who started between one and five lessons of ICBT in the previous year and did not formally withdraw from treatment (n = 31 patients). The therapists who were audited were provided feedback four times over a one-year period from October 2018 to September 2019. Overall, in all audit periods, we found a low percentage of undesirable therapist behaviours (i.e., therapists displayed the behaviour in 12% or less of the total emails sent). For most therapist behaviours, we saw a trend towards improvement across the four audit cycles. Three therapist behaviours (i.e., Failure to Ask One Question to the Patient, Poor Instructions, Not Linking Email to Course Content) did not follow this pattern and were flagged for clinical discussion to determine why behaviours were elevated and whether these behaviours represented unrealistic expectations. The process was valuable for monitoring and improving therapist behaviours and highlights the need for future research on standards for therapist behaviours (e.g., which behaviours to focus on, setting acceptable levels of undesirable behaviour).

Making Internet-delivered cognitive behaviour therapy scalable for cancer survivors: a randomized non-inferiority trial of self-guided and technician-guided therapy

PURPOSE

To compare the effectiveness and acceptability of two low-intensity methods of offering a transdiagnostic Internet-delivered cognitive behaviour therapy (ICBT) intervention for treating symptoms of anxiety and depression among cancer survivors.

METHODS

Cancer survivors with symptoms of anxiety or depression (n = 86) were randomly assigned to receive a transdiagnostic ICBT programme (Wellbeing After Cancer) that was either guided by a technician (n = 42) or self-guided (n = 44). Measures of anxiety, depression, fear of cancer recurrence, and quality of life were completed at pre-treatment, post-treatment, and 4 weeks following treatment completion.

RESULTS

Large within-group effect sizes were observed on measures of depression, anxiety, and mental health-related quality of life (d range, 0.98-1.86) at post-treatment. Medium effects were found for reductions in fear of cancer recurrence (d range, 0.65-0.78). Non-inferiority was established for the primary outcome measures of anxiety and depression. All participants reported high satisfaction ratings of the programme; however, technician-guided participants were slightly more satisfied with their level of support (d = 0.57, p = .014).

CONCLUSIONS

The Wellbeing After Cancer Course was associated with improved levels of anxiety, depression, fear of cancer recurrence, and quality of life, regardless of how ICBT was offered.

IMPLICATIONS FOR CANCER SURVIVORS

ICBT is emerging as an accessible and effective treatment for depression, anxiety, and fear of cancer recurrence in cancer survivors. The success of non-therapist-guided options increases the potential scalability of ICBT, which is particularly valuable for cancer survivors from rural areas who have less access to mental health services.

A comparison of the characteristics and treatment outcomes of migrant and Australian-born users of a national digital mental health service

BACKGROUND

To explore the characteristics and compare clinical outcomes of non-Australian born (migrant) and Australian-born users of an Australian national digital mental health service.

METHODS

The characteristics and treatment outcomes of patients who completed online treatment at the MindSpot Clinic between January 2014 and December 2016 and reported a country of birth other than Australia were compared to Australian-born users. Data about the main language spoken at home were used to create distinct groups. Changes in symptoms of depression and anxiety were measured using the Patient Health Questionnaire-9 Item (PHQ-9), and Generalized Anxiety Disorder Scale - 7 Item (GAD-7), respectively.

RESULTS

Of 52,020 people who started assessment at MindSpot between 1st January 2014 and 22nd December 2016, 45,082 reported a country of birth, of whom 78.6% (n = 35,240) were Australian-born, and 21.4% (n = 9842) were born overseas. Of 6782 people who completed the online treatment and reported country of birth and main language spoken at home, 1631 (24%) were migrants, 960 (59%) were from English-speaking countries, and 671 (41%) were from non-English speaking countries. Treatment-seeking migrant users reported higher rates of tertiary education than Australian-born users. The baseline symptom severity, and rates of symptom reduction and remission following online treatment were similar across groups.

CONCLUSIONS

Online treatment was associated with significant reductions in anxiety and depression in migrants of both English speaking and non-English speaking backgrounds, with outcomes similar to those obtained by Australian-born patients. DMHS have considerable potential to help reduce barriers to mental health care for migrants.

Stakeholder Perceptions of Internet-Delivered Cognitive Behavior Therapy as a Treatment Option for Alcohol Misuse: Qualitative Analysis

BACKGROUND

Internet-delivered cognitive behavior therapy (ICBT) has been found to be effective for treating alcohol misuse in research trials, but it is not available as part of routine care in Canada. Recent recommendations in the literature highlight the importance of integrating perspectives from both patient and health care stakeholders when ICBT is being implemented in routine practice settings.

OBJECTIVE

This study aimed to gain an understanding of how ICBT is perceived as a treatment option for alcohol misuse by interviewing diverse stakeholders. Specifically, the objectives were to (1) learn about the perceived advantages and disadvantages of ICBT for alcohol misuse and (2) elicit recommendations to inform implementation efforts in routine practice.

METHODS

A total of 30 participants representing six stakeholder groups (ie, patients, family members, academic experts, frontline managers, service providers, and health care decision makers) participated in semistructured interviews. To be included in the study, stakeholders had to reside in Saskatchewan, Canada, and have personal or professional experience with alcohol misuse. Interviews were transcribed verbatim, anonymized, and analyzed using thematic analysis.

RESULTS

Stakeholders identified numerous advantages of ICBT for alcohol misuse (eg, accessibility, convenience, privacy, relevance to technology-based culture, and fit with stepped care) and several disadvantages (eg, lack of internet access and technological literacy, isolation, less accountability, and unfamiliarity with ICBT). Stakeholders also provided valuable insight into factors to consider when implementing ICBT for alcohol misuse in routine practice. In terms of intervention design, stakeholders recommended a 6- to 8-week guided program that uses Web-based advertising, point-of-sale marketing, and large-scale captive audiences to recruit participants. With regard to treatment content, stakeholders recommended that the program focus on harm reduction rather than abstinence; be evidence based; appeal to the diverse residents of Saskatchewan; and use language that is simple, encouraging, and nonjudgmental. Finally, in terms of population characteristics, stakeholders felt that several features of the alcohol misuse population, such as psychiatric comorbidity, readiness for change, and stigma, should be considered when developing an ICBT program for alcohol misuse.

CONCLUSIONS

Stakeholders' insights will help maximize the acceptability, appropriateness, and adoption of ICBT for alcohol misuse and in turn contribute to implementation success. The methodology and findings from this study could be of benefit to others who are seeking to implement ICBT in routine practice.

An Internet-Delivered Cognitive Behavioral Therapy for Depression and Anxiety Among Clients Referred and Funded by Insurance Companies Compared With Those Who Are Publicly Funded: Longitudinal Observational Study

BACKGROUND

Anxiety and depression are leading causes of disability but are often undertreated. Internet-delivered cognitive behavioral therapy (ICBT) improves access to treatment by overcoming barriers to obtaining care. ICBT has been found to be efficacious in research trials and routine care, but there is limited research of ICBT when it is recommended and funded by insurance companies for clients on or recently in receipt of disability benefits or accommodations.

OBJECTIVE

The aim of this study was to examine ICBT engagement, treatment satisfaction, and effectiveness among individuals involved with 2 insurance companies. The 2 samples were benchmarked against published outcomes from a publicly funded (PF) ICBT clinic.

METHODS

Individuals who were on or recently in receipt of disability benefits and were either insurance company (IC) employees (n=21) or IC plan members (n=19) were referred to ICBT funded by the respective insurance companies. Outcomes were benchmarked against outcomes of ICBT obtained in a PF ICBT clinic, with clients in the clinic divided into those who reported no involvement with insurance companies (n=414) and those who were on short-term disability (n=44). All clients received the same 8-week, therapist-assisted, transdiagnostic ICBT course targeting anxiety and depression. Engagement was assessed using completion rates, log-ins, and emails exchanged. Treatment satisfaction was assessed posttreatment. Depression, anxiety, and disability measures were administered pretreatment, posttreatment, and at 3 months.

RESULTS

All samples showed high levels of ICBT engagement and treatment satisfaction. IC employees experienced significant improvement at posttreatment (depression d=0.77; anxiety d=1.13; and disability d=0.91) with outcomes maintained at 3 months. IC plan members, who notably had greater pretreatment disability than the other samples, experienced significant moderate effects at posttreatment (depression d=0.58; anxiety d=0.54; and disability d=0.60), but gains were not maintained at 3 months. Effect sizes at posttreatment in both IC samples were significantly smaller than in the PF sample who reported no insurance benefits (depression d=1.14 and anxiety d=1.30) and the PF sample who reported having short-term disability benefits (depression d=0.95 and anxiety d=1.07). No difference was seen in effect sizes among IC employees and the PF samples on disability. However, IC plan members experienced significantly smaller effects on disability d=0.60) compared with the PF sample with no disability benefits d=0.90) and those on short-term disability benefits d=0.94).

CONCLUSIONS

Many clients referred and funded by insurance companies were engaged with ICBT and found it acceptable and effective. Results, however, were not maintained among those with very high levels of pretreatment disability. Small sample sizes in the IC groups are a limitation. Directions for research related to ICBT funded by insurance companies have been described.

Internet-based CBT for patients with depressive disorders in primary and psychiatric care: Is it effective and does comorbidity affect outcome?

Internet-based cognitive behavior therapy (ICBT) has proved effective in reducing mild to moderate depressive symptoms. However, only a few studies have been conducted in a regular healthcare setting which limits the generalizability of the results. The influence of psychiatric comorbidity on outcome is not well understood. In the current study, patients with mild to moderate depressive symptoms in primary and psychiatric care were interviewed using the SCID-I and SCID-II to assess psychiatric diagnoses. Those included were randomly allocated to ICBT (n = 48) or to an active control condition (n = 47). Both groups received therapist support. At post-treatment, ICBT had reduced depressive symptoms on the BDI-II more than the active control intervention (p = .021). However, the difference between groups was no longer significant at the 6-, 12- or 24-month follow-ups. The within-group effect size after ICBT (BDI-II) was large (d = 1.4). A comorbid anxiety disorder didn't moderate the outcome, while the presence of a personality disorder predicted significantly less improvement in depressive symptoms. ICBT had a large effect on depressive symptoms in a sample from regular healthcare. It is possible to obtain a large effect from ICBT despite comorbid anxiety, however, including patients with a comorbid personality disorder in the current form of ICBT seems questionable.

Transdiagnostic cognitive behavioral therapy for the treatment of emotional disorders: A preliminary open trial

BACKGROUND AND OBJECTIVES

To assess the efficacy of a transdiagnostic cognitive behavioral therapy (tCBT) protocol for the treatment of emotional disorders with individuals that have a principal or comorbid depressive diagnosis.

METHODS

Treatment-seeking adults meeting diagnostic criteria for a depressive disorder were enrolled in a 12-week tCBT open trial aimed at addressing the underlying core pathology of emotional disorders. Clinician severity ratings (CSRs) regarding principal and comorbid diagnoses, and overall severity as well as clinical global impression-severity (CGI-S) ratings were assessed at pre- and post-treatment and 4-month follow-up. Clinician's provided a clinical global impression-improvement (CGI-I) rating post-treatment and at 4-month follow-up. Depressive and anxiety symptoms were measured at pre-treatment and session-by-session using self-report measures (BDI-II and ADDQ).

RESULTS

Repeated measure ANOVAs indicated a reduction in principal diagnosis severity, overall severity, and CGI-S with large effects observed post-treatment (Cohen's ds = 1.29-1.92) and at 4-month follow-up (Cohen's ds = 0.77-1.04). Mixed-effect regression modelling demonstrated a decrease in depressive and anxiety symptoms over the course of treatment. CGI-I ratings identified 63.64% participants as treatment responders both post-treatment and at 4-month follow-up.

LIMITATIONS

The uncontrolled nature of the trial and small sample size are the main limitations to generalizability of the findings.

CONCLUSIONS

The findings, although preliminary, provide additional evidence for the utilization of tCBT in the effective treatment of emotional disorders. Further research into the implementation of the tCBT for emotional disorders protocol through a randomized controlled trial involving groups of participants with a range of emotional disorder diagnoses is warranted.

Effectiveness of internet-delivered cognitive behavioural therapy in reducing sickness absence among young employees with depressive symptoms: study protocol for a large-scale pragmatic randomised controlled trial

INTRODUCTION

Depression is a highly prevalent condition with typical onset in early adulthood. Internet-delivered cognitive behavioural therapy (iCBT) is a promising cost-effective and more widely available alternative to face-to-face CBT. However, it is not known whether it can reduce sickness absence in employees showing depressive symptoms. The randomised controlled trial component of the DAQI (Depression and sickness absence in young adults: a quasi-experimental trial and web-based treatment intervention) project aims to investigate if iCBT is effective in reducing sickness absence compared with care as usual (CAU) among young employees with depressive symptoms in primary care provided in an occupational health setting.

METHODS AND ANALYSIS

This study will use a randomised controlled single-centre service-based trial of an existing iCBT programme (Mental Hub iCBT for Depression) to evaluate whether or not this treatment can reduce the number of sickness absence days in public sector employees aged 18-34 years who present at the occupational health service with mild depressive symptoms (score ≥9 on the Beck Depression Inventory-IA). Control participants will be offered CAU, with no constraints regarding the range of treatments. The active condition will consist of seven weekly modules of iCBT, with support from a web therapist. Primary outcome will be participants' all-cause sickness absence as indicated in employer's and national administrative records up to 6 months from study entry. Secondary outcomes relating to long-term sickness absence (over 11 calendar days) for mental and musculoskeletal disorders and psychotropic medication use will be obtained from the Finnish Social Insurance Institution's administrative records; and short sickness absence spells (up to 11 calendar days) will be extracted from employer's records. Analyses will be conducted on an intention-to-treat basis.

ETHICS AND DISSEMINATION

The Coordinating Ethics Committee of the Hospital District of Helsinki and Uusimaa has approved the study (HUS/974/2019). The results will be published in peer-reviewed scientific journals and in publications for lay audience.

Evaluation of The Practitioner Online Referral and Treatment Service (PORTS): the first 18 months of a state-wide digital service for adults with anxiety, depression, or substance use problems

The Practitioner Online Referral and Treatment Service (PORTS) is a new digital mental health service (DMHS) providing assessment, treatment, and consultation across Western Australia, for adults with anxiety, depression, or substance use problems, and experiencing financial hardship or geographical disadvantage. From July 2017 to December 2018, a total of 2,527 individuals were referred to PORTS. Of these, 150 (6%) did not give consent for their results to be analysed. Of the remaining 2,377 patients, 615 (26%) could not be contacted to confirm the referral, 596 (25%) received assessment or information from PORTS, 427 (18%) were referred to another service, and 739 (31%) commenced treatment at PORTS. Almost half (47%) of patients were from areas with significant socio-economic disadvantage. Those referred by another mental health service were more likely to engage in treatment than those referred by a General Practitioner (GP). Overall outcomes were excellent, with large effect sizes (Cohen's d: 1.1-1.4), from assessment to post-treatment and 3-month follow-up, reliable deterioration was low, and GP and patient satisfaction was high. These results indicate that the PORTS DMHS model is a promising method for engaging primary care patients with anxiety and depression, including those experiencing financial and geographical disadvantage.

Negative effects associated with internet-delivered cognitive behaviour therapy: An analysis of client emails

Internet-delivered cognitive behaviour therapy (ICBT) is an efficacious form of treatment for anxiety and depression, yet it is still possible for clients to experience negative effects associated with treatment. In the ICBT literature, the term negative effects is broadly used to refer to all potentially adverse or unwanted events or experiences that are perceived as undesirable by the client and may or may not be associated with long-term symptoms or distress. Previous ICBT studies have asked clients to retrospectively describe negative effects at post-treatment; however, no research has examined the content of clients' emails to their therapist to see whether clients are reporting negative effects as they arise. In the current study, 96 clients (80 completers; 16 non-completers) were randomly selected from a published ICBT trial and directed content analysis was used to examine client emails for mention of negative effects. In addition, correlational analyses were used to examine the relationship between negative effects and: 1) demographic characteristics; 2) treatment engagement; 3) treatment satisfaction; 4) working alliance; and 5) symptom outcomes among completers. The results indicated that 61.5% of clients experienced at least one negative effect during treatment, although total number of negative effects was not significantly correlated with client demographic characteristics, lessons completed, working alliance, treatment satisfaction, or symptom outcomes. Among completers, technical difficulties, implementation problems, and negative emotional states were the most commonly reported negative effects, whereas dropout was the most commonly reported negative effect by non-completers. Negative effects that have been identified in previous research, such as symptom deterioration, novel symptoms, and severe adverse events, were not identified in client emails. The high incidence of negative effects in the current study suggests there may be value in systematically monitoring client emails for negative effects throughout treatment as a supplement to retrospective post-treatment reports. This will give therapists the opportunity to intervene as negative effects occur and potentially mitigate any impact they have on treatment outcomes. Future research, both qualitative and quantitative, is needed to gain a more nuanced understanding of negative effects associated with ICBT.

Examining an internet-delivered intervention for anxiety and depression when delivered as a part of routine care for university students: A phase IV trial

BACKGROUND

There has been growing interest in the potential of emerging internet-delivered psychological treatments for supporting the mental health needs of university students. However, no large-scale prospective effectiveness trials examining their real-world potential have been reported.

OBJECTIVE

The aim of the current study was to evaluate the acceptability and effectiveness of a brief, 5-week, internet-delivered and therapist-guided intervention for anxiety and depression, when delivered as part of routine care by a university counselling service.

DESIGN

A large, prospective, single-group Phase-IV clinical trial. Students (n = 1326) engaging with the university counselling service were provided the opportunity to receive the intervention based on their preferences and identified needs. Students completed standardised measures of anxiety and depression at pre-treatment, each week of the intervention, post-treatment and 3-month follow-up.

RESULTS

Over a 4 year period, 1081 students (10% of those presenting to the counselling service) participated in the intervention. Large clinical reductions in symptoms of both anxiety (% reduction = 41%; Cohen's d = 0.94) and depression (% reduction = 36%; Cohen's d = 0.81) were observed alongside high levels of acceptability. The intervention required relatively little counsellor time (M = 36.28 mins; SD = 20.56) per student, and symptom deterioration was observed in less than 5% of students.

CONCLUSION

The findings of the current study are supportive of internet-delivered interventions provided as routine care to university students. Further research is needed to carefully explore whether these interventions could be used with a larger proportion of students presenting to counselling services, paying close attention to acceptability, engagement and clinical outcomes.

From Research to Practice: Ten Lessons in Delivering Digital Mental Health Services

There is a large body of research showing that psychological treatment can be effectively delivered via the internet, and Digital Mental Health Services (DMHS) are now delivering those interventions in routine care. However, not all attempts to translate these research outcomes into routine care have been successful. This paper draws on the experience of successful DMHS in Australia and Canada to describe ten lessons learned while establishing and delivering internet-delivered cognitive behavioural therapy (ICBT) and other mental health services as part of routine care. These lessons include learnings at four levels of analysis, including lessons learned working with (1) consumers, (2) therapists, (3) when operating DMHS, and (4) working within healthcare systems. Key themes include recognising that DMHS should provide not only treatment but also information and assessment services, that DMHS require robust systems for training and supervising therapists, that specialist skills are required to operate DMHS, and that the outcome data from DMHS can inform future mental health policy. We also confirm that operating such clinics is particularly challenging in the evolving funding, policy, and regulatory context, as well as increasing expectations from consumers about DMHS. Notwithstanding the difficulties of delivering DMHS, we conclude that the benefits of such services for the broader community significantly outweigh the challenges.

Facilitating access to iCBT: a randomized controlled trial assessing a translated version of an empirically validated program using a minimally monitored delivery model

BACKGROUND

Despite its established efficacy, access to internet-delivered CBT (iCBT) remains limited in a number of countries. Translating existing programs and using a minimally monitored model of delivery may facilitate its dissemination across countries.

AIMS

This randomized control trial aims to evaluate the efficacy of an iCBT transdiagnostic program translated from English to French and offered in Canada using a minimally monitored delivery model for the treatment of anxiety and depression.

METHOD

Sixty-three French speakers recruited in Canada were randomized to iCBT or a waiting-list. A French translation of an established program, the Wellbeing Course, was offered over 8 weeks using a minimally monitored delivery model. Primary outcome measures were the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9), which were obtained pre-treatment, post-treatment and at 3-month follow-up.

RESULTS

Mixed-effects models revealed that participants in the treatment group had significantly lower PHQ-9 and GAD-7 scores post-treatment than controls with small between-groups effect sizes (d = 0.34 and 0.37, respectively). Within-group effect sizes on primary outcome measures were larger in the treatment than control group. Clinical recovery rates on the PHQ-9 and GAD-7 were significantly higher among the treatment group (40 and 56%, respectively) than the controls (13 and 16%, respectively).

CONCLUSIONS

The provision of a translated iCBT program using a minimally monitored delivery model may improve patients' access to treatment of anxiety and depression across countries. This may be an optimal first step in improving access to iCBT before sufficient resources can be secured to implement a wider range of iCBT services.

Development of the Internet-Delivered Cognitive Behaviour Therapy Undesirable Therapist Behaviours Scale (ICBT-UTBS)

Internet-delivered cognitive behaviour therapy (ICBT) is often provided with therapist assistance via asynchronous secure emails, but there is limited research on undesirable behaviours exhibited by therapists in their correspondence with patients. In this study, an ICBT-Undesirable Therapist Behaviour Scale (ICBT-UTBS) was developed and used to assess the nature, frequency, and correlates of undesirable therapist behaviours in routine practice. Thematic analysis was used to identify undesirable therapist behaviours in 720 emails sent to 91 randomly selected patients in the context of a previous clinical trial of transdiagnostic ICBT for depression and anxiety. The following undesirable behaviours were identified, albeit infrequently, in therapist emails: inadequate detail (6.4%), unaddressed content (4.0%), unsupportive tone (0.6%), missed correspondence (0.6%), inappropriate self-disclosure (0.6%), and unmanaged risk (0.3%). At least one undesirable behaviour was found in 10.7% of all emails coded. Moreover, 37.4% of patients received at least one email containing an undesirable therapist behaviour. Number of undesirable therapist behaviours was not correlated with patient engagement, working alliance, treatment satisfaction, or patient outcome variables. However, undesirable therapist behaviours were negatively correlated with patient gender and therapist characteristics (e.g., clinical setting, therapist profession). The results of the present study provide preliminary psychometric support for the ICBT-UTBS, a measure of ICBT treatment integrity. In the future, the ICBT-UTBS should be used in combination with the ICBT-Therapist Rating Scale (ICBT-TRS), a measure of desirable or recommended therapist behaviours, for training purposes and to monitor ICBT therapists in routine practice.

Transdiagnostic psychiatry: a systematic review

The usefulness of current psychiatric classification, which is based on ICD/DSM categorical diagnoses, remains questionable. A promising alternative has been put forward as the "transdiagnostic" approach. This is expected to cut across existing categorical diagnoses and go beyond them, to improve the way we classify and treat mental disorders. This systematic review explores whether self-defining transdiagnostic research meets such high expectations. A multi-step Web of Science literature search was performed according to an a priori protocol, to identify all studies that used the word "transdiagnostic" in their title, up to May 5, 2018. Empirical variables which indexed core characteristics were extracted, complemented by a bibliometric and conceptual analysis. A total of 111 studies were included. Most studies were investigating interventions, followed by cognition and psychological processes, and neuroscientific topics. Their samples ranged from 15 to 91,199 (median 148) participants, with a mean age from 10 to more than 60 (median 33) years. There were several methodological inconsistencies relating to the definition of the gold standard (DSM/ICD diagnoses), of the outcome measures and of the transdiagnostic approach. The quality of the studies was generally low and only a few findings were externally replicated. The majority of studies tested transdiagnostic features cutting across different diagnoses, and only a few tested new classification systems beyond the existing diagnoses. About one fifth of the studies were not transdiagnostic at all, because they investigated symptoms and not disorders, a single disorder, or because there was no diagnostic information. The bibliometric analysis revealed that transdiagnostic research largely restricted its focus to anxiety and depressive disorders. The conceptual analysis showed that transdiagnostic research is grounded more on rediscoveries than on true innovations, and that it is affected by some conceptual biases. To date, transdiagnostic approaches have not delivered a credible paradigm shift that can impact classification and clinical care. Practical "TRANSD"iagnostic recommendations are proposed here to guide future research in this field.

Preference trial of internet-delivered cognitive behaviour therapy comparing standard weekly versus optional weekly therapist support

Emerging evidence from research trials suggests that Internet-delivered cognitive behaviour therapy (ICBT) produces similar symptom improvements whether patients receive weekly therapist support (standard support) or therapist support only when requested (optional support). It remains unknown, however, how many patients receiving ICBT as part of routine clinical care would prefer optional support compared to standard support and how outcomes compare when patients select their preferred treatment option. In this uncontrolled trial, we investigated patient preference and outcomes for standard versus optional support among patients with depression and or anxiety who were offered an 8-week transdiagnostic ICBT intervention in routine care. Of 401 patients accepted for ICBT, 22% selected optional support and 78% selected standard support. At assessment, patients who selected optional support had lower symptoms of anxiety and panic than patients who selected standard support. At post-treatment, both groups achieved similar large improvements in symptoms of anxiety and depression, with improvements sustained at 3-month follow-up. Patients receiving optional support sent and received fewer messages compared to patients receiving standard support. This study demonstrates the potential of optional therapist support to meet the needs and preferences of patients and to also reduce therapist costs in routine care.

What are Clients Asking Their Therapist During Therapist-Assisted Internet-Delivered Cognitive Behaviour Therapy? A Content Analysis of Client Questions

BACKGROUND

Although internet-delivered cognitive behaviour therapy (ICBT) yields large clinical outcomes when accompanied by therapeutic support, a portion of clients do not benefit from treatment. In ICBT, clients review treatment materials online typically on a weekly basis. A key component of therapist-assistance involves answering questions as clients review and work on assignments related to the treatment materials.

AIMS

The goal of this study was to enhance understanding of the nature of client questions posed during ICBT and examine potential associations between the number of questions asked and treatment outcomes in order to provide insight into how to improve ICBT for future users.

METHOD

Content analysis was used to qualitatively analyse and identify questions that 80 clients asked their designated therapist over the course of an 8-week ICBT programme for anxiety and depression.

RESULTS

On average, clients sent six emails during the course of treatment, of which less than two questions were asked. Of the 137 questions posed by clients, 46.72% reflected questions designed to enhance understanding and apply the material and techniques reviewed in the programme. Additional questions were categorized as clarifying the therapeutic process (22.62%), addressing technical challenges (18.25%), and seeking assistance with problems outside the scope of ICBT (12.41%). Number of client questions asked was not significantly correlated with the number of lessons completed, symptom change, or perceptions of therapeutic alliance.

CONCLUSIONS

Findings can inform future practitioners who deliver ICBT of what to expect with this treatment approach and also assist in the development of future ICBT programmes.
