Measurement of Symptom Change Following Web-Based Psychotherapy: Statistical Characteristics and Analytical Methods for Measuring and Interpreting Change

Making the most out of timeseries symptom data: A machine learning study on symptom predictions of internet-based CBT

Objective

Predicting who will not benefit enough from Internet-Based Cognitive Behavioral (ICBT) Therapy early on can assist in better allocation of limited mental health care resources. Repeated measures of symptoms during treatment is the strongest predictor of outcome, and we want to investigate if methods that explicitly account for time-dependency are superior to methods that do not, with data from (a) only two pre-treatment timepoints and (b) the pre-treatment timepoints and three timepoints during initial treatment.

Methods

We use 1) commonly used time-independent methods (i.e., Linear Regression and Random Forest models) and 2) time-dependent methods (i.e., multilevel model regression, mixed-effects random forest, and a Long Short-Term Memory model) to predict symptoms during treatment, including the final outcome. This is done with symptom scores from 6436 ICBT patients from regular care, using robust multiple imputation and nested cross-validation methods.

Results

The models had a 14 %-12 % root mean squared error (RMSE) in predicting the post-treatment outcome, corresponding to a balanced accuracy of 67-74 %. Time-dependent models did not have higher accuracies. Using data for the initial treatment period (b) instead of only from before treatment (a) increased prediction results by 1.3 % percentage points (12 % to 10.7 %) RMSE and 6 % percentage points BACC (69 % to 75 %).

Conclusion

Training prediction models on only symptom scores of the first few weeks is a promising avenue for symptom predictions in treatment, regardless of which model is used. Further research is necessary to better understand the interaction between model complexity, dataset length and width, and the prediction tasks at hand.

The association between physical intervention use and treatment outcomes in patients participating in an online and psychologically informed pain management program

BACKGROUND

The availability of multidisciplinary care for the management of chronic pain is uncommon outside specialist clinics. The present study aims to determine the physical intervention use of patients participating in an online psychological pain management program and whether exposure to physical interventions in these patients alters treatment outcomes compared with patients who do not access physical interventions.

METHODS

Data were obtained from 2 previously published randomized controlled trials of an online psychological pain management program. Physical intervention exposure (categories: none, 1-3 sessions, 4+ sessions) was assessed at baseline, after treatment, and at 3-month follow-up. Primary outcomes included depression, anxiety, pain intensity, and pain-related disability. Generalized estimating equation models were used to compare treatment outcomes among those with different physical intervention frequencies and periods of exposure. We assessed whether changes in primary outcomes differed (moderated) by the period and category of physical intervention exposure.

RESULTS

Of the patients (n = 1074) who completed the baseline questionnaire across both randomized controlled trials, 470 (44%) reported physical intervention use at baseline, 383 (38%) reported physical intervention use after treatment, and 363 (42%) reported physical intervention use at 3-month follow-up. On average, there were moderate-large reductions from baseline to after treatment with respect to all outcomes (Cohen's d = 0.36-0.82). For all outcomes, the interaction of time by physical intervention exposure was statistically nonsignificant.

CONCLUSION

A substantial proportion of patients who participated in a psychologically informed pain management program were establishing, continuing, or stopping additional physical interventions. The frequency of and period of exposure to physical interventions did not appear to moderate treatment outcomes.

An online therapist-guided ultra-brief treatment for depression and anxiety: a randomized controlled trial

BACKGROUND

There are many barriers to engaging in current psychological treatments, including time, cost, and availability. Ultra-brief treatments overcome some of these barriers by delivering therapeutic information and skills using significantly less time than standard-length treatments. We developed a therapist-guided online ultra-brief treatment for depression and anxiety and compared it to an existing 8-week, 5-lesson therapist-guided standard-length treatment and a waitlist control.

METHODS

In a randomized controlled trial, adults with self-reported depression or anxiety were randomized (1:1:1) to the ultra-brief treatment, standard-length treatment, or waitlist control. The primary outcomes were depression symptoms and anxiety symptoms assessed at baseline, 5-weeks later, 9-weeks later (primary timepoint), and 3-months later. The trial was prospectively registered.

RESULTS

Between 7 February 2022, and 16 August 2022, 242 participants were enrolled in the ultra-brief treatment (n = 85), standard-length treatment (n = 80), and waitlist control (n = 77). Participants were mostly women with an average age of 48.56 years. At 9-weeks post-baseline, participants in the ultra-brief treatment group reported significantly lower depression (between groups d = 0.41) and anxiety (d = 0.53) than the waitlist control. The ultra-brief treatment was non-inferior for anxiety at both 9-weeks and 3-months follow-up. Non-inferiority for depression was observed at 9-weeks.

CONCLUSIONS

The online ultra-brief treatment resulted in significant reductions in depression and anxiety that were non-inferior to a longer treatment course after 9-weeks. Remotely delivered ultra-brief treatments have the potential to provide accessible and effective care for those who cannot, or would prefer not to, access longer psychological interventions.

Efficacy and acceptability of a self-guided internet-delivered cognitive-behavioral educational program for obsessive-compulsive symptoms with international recruitment

Cognitive-behavioural therapy is an effective treatment for obsessive-compulsive disorder (OCD). However, there are many barriers in accessing this treatment, with stigma being a particularly prominent barrier for many patients. Self-guided internet-delivered cognitive-behavioural therapy (ICBT), which does not require any contact with a therapist, has the potential to overcome this barrier. However, there is limited research on the efficacy of self-guided ICBT for OCD. The aim of the current study was to examine the efficacy of self-guided ICBT for OCD in a large international sample. Two hundred and sixteen participants were included in the study (Mage = 34.00; SD = 12.57; 72.7% female). On the primary outcome measure, the Yale-Brown Obsessive-Compulsive Scale (YBOCS), a medium within-group effect size was found from pre-treatment to post-treatment (g = 0.63), and a large within-group effect size was found from pre-treatment to 3-month follow-up (g = 0.98). Approximately one-quarter to one-third of participants met criteria for clinically significant improvement at post-treatment and 3-month follow-up (11% and 17% met criteria for remission at post-treatment and 3-month follow-up, respectively). These results demonstrate that self-guided ICBT may be an efficacious treatment for individuals with OCD who cannot or do not wish to engage with a mental health professional, resulting in medium to large effect sizes.

Psychometric evaluation of an adult post-COVID-19 symptom tool: a development and validation study

The objective of this study was aimed to develop and validate an instrument for post-COVID-19 symptoms in adults. Data were collected from adults with a previous COVID-19 diagnosis in Taiwan. We developed the initial instrument through systematic review and expert feedback. Its validity was tested using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and criterion-related validity, while its reliability was tested using Cronbach's alpha. In total, 310 adults participated in this study. Examination of the EFA clearly classified a five-factor model with 24 items (Kaiser-Meyer-Olkin = 0.903; Bartlett's test of sphericity: X2 = 5242.956, df = 276, p < 0.01). The goodness of fit indices of the CFA were as follows: chi-square = 635.172 (p < 0.01), normed chi-square = 2.669, standardized root mean square residual = 0.077, root mean square error of approximation = 0.073, comparative fit index = 0.922, and Tuker and Lewis index = 0.910. The value of Cronbach's alpha coefficient for the total items was 0.941, and the values for the subscales ranged from 0.813 to 0.924. The instrument exhibited acceptable psychometric properties, proving it to be a valuable tool for evaluating post-COVID-19 symptoms in patients at hospitals.

Treating child anxiety using family-based internet delivered cognitive behavior therapy with brief therapist guidance: A randomized controlled trial

Online treatment delivery has the potential to increase access to evidence-based mental health care for children with anxiety disorders. Using a randomized controlled trial design, we evaluated the efficacy of Cool Kids Online, a family-based and therapist supported internet-delivered cognitive behavioral treatment (CBT) designed to target anxiety disorders in children. Ninety-five children aged 7-12 years with a DSM-5 anxiety disorder were randomly allocated to Cool Kids Online or a waitlist control. Children were assessed at baseline, week 11, and 6-months following treatment. Children in waitlist received treatment after week 11 and also completed assessments immediately and six months after treatment, allowing treatment maintenance to be evaluated for all children. Compared to waitlist, Cool Kids Online led to significantly greater remission of anxiety disorders (primary and all anxiety diagnoses) and greater reduction of caregiver-reported anxiety symptoms and interference at week 11. Child-reported anxiety symptoms and interference and child- and caregiver-reported depressive or externalizing symptoms did not differ significantly between conditions. Medium to large within-treatment effects were observed for all children from pre to post treatment with post treatment effects maintained until follow-up. Overall, the findings provide support for the efficacy of the program in treating anxiety.

Evaluation of a therapist-guided virtual psychological pain management program when provided as routine care: a prospective pragmatic cohort study

INTRODUCTION

Numerous randomized controlled trials have evaluated the outcomes of internet-delivered psychological pain management programs (PMPs) as a way of increasing access to care for people with chronic pain. However, there are few reports of the effectiveness of these PMPs when provided as part of routine care.

METHODS

The present study sought to report the clinical and demographic characteristics of users (n = 1367) and examine the effectiveness of an established internet-delivered psychological PMP program in improving several pain-related outcomes, when offered at a national digital mental health service over a 5-year period. It also sought to comprehensively explore predictors of treatment commencement, treatment completion, and clinical improvement.

RESULTS

Evidence of clinical improvements (% improvement; Hedges g) were found for all outcomes, including pain interference (18.9%; 0.55), depression (26.1%; 0.50), anxiety (23.9%; 0.39), pain intensity (12.8%; 0.41), pain self-efficacy (-23.8%; -0.46) and pain-catastrophizing (26.3%; 0.56). A small proportion of users enrolled but did not commence treatment (13%), however high levels of treatment completion (whole treatment = 63%; majority of the treatment = 75%) and satisfaction (very satisfied = 45%; satisfied = 37%) were observed among those who commenced treatment. There were a number of demographic and clinical factors associated with commencement, completion and improvement, but no decisive or dominant predictors were observed.

DISCUSSION

These findings highlight the effectiveness and acceptability of internet-delivered psychological PMPs in routine care and point to the need to consider how best to integrate these interventions into the pathways of care for people with chronic pain.

An open trial of the feasibility of brief internet-delivered acceptance and aommitment therapy (iACT) for chronic anxiety and depression

Anxiety and depressive disorders are common, often chronic and result in significant disability and distress. The delivery of psychological interventions via the internet is now recognised to be a safe and effective way to treat these disorders. The predominant therapeutic model in clinical trials and in routine care has been cognitive-behavioural therapy (CBT), which helps patients identify and modify unhelpful thoughts and behaviours. However, other models of treatment for anxiety and depression, such as acceptance and commitment therapy (ACT), which uses the examination of both positive and negative experiences in the service of living a personally meaningful and values-based life, have been developed and tested, although most of these interventions are long and require more clinician support to ensure adherence and achieve positive outcomes. The aim of the present study was to examine the feasibility of a new brief, clinician supported transdiagnostic internet-delivered (iACT) program, designed to treat symptoms of both anxiety and depression and improve social function. A single-group open trial was conducted on 24 adults with long-term symptoms of anxiety and depression. The course is comprised of five online modules delivered over 8 weeks either self-guided or with support from a clinician. There was a high course completion rate (70 %) and a high level of satisfaction with the course (94 % satisfied or very satisfied). Significant clinical improvement in our primary outcome measures (within-group Cohen's d) of anxiety (d ≥ 0.62), depression (d ≥ 0.63), disability (d ≥ 0.43) and quality of life (d ≥ -0.57) were observed at posttreatment. Relatively little clinician time was required per participant (M = 30.6 min, SD = 5.7). The findings of the current study support the feasibility and potential of a transdiagnostic iACT treatment for adults experiencing long-term symptoms of anxiety and depression, including those patients who have not derived benefit from other treatments.

The impact of obesity and overweight on response to internet-delivered cognitive behavioural therapy for adults with chronic health conditions

BACKGROUND

There is growing evidence that internet-delivered cognitive behavioural therapy (iCBT) can improve functioning and reduce psychological distress in people with chronic health conditions. Obesity frequently co-occurs with chronic health conditions, yet its impact on response to psychological interventions in this population is not known. The current study examined associations between BMI and clinical outcomes (depression, anxiety, disability, and satisfaction with life) following a transdiagnostic iCBT program targeting adjustment to chronic illness.

METHODS

Participants from a large randomised controlled trial, who provided information on height and weight, were included (N = 234; mean age= 48.32, SD = 13.80; mean BMI = 30.43, SD = 8.30, range 16.18-67.52; 86.8% female). The influence of baseline BMI range on treatment outcomes at post-treatment and 3-month follow-up was examined using generalized estimating equations. We also examined changes in BMI and in participants' perceived impact of weight on their health.

RESULTS

Improvement in all outcomes occurred across BMI ranges; additionally, persons with obesity or overweight generally experienced greater symptom reductions than those within a healthy weight range. A greater proportion of participants with obesity achieved clinically significant change on key outcomes (e.g., depression: 32% [95% CI: 25%, 39%]) than participants with a healthy weight (21% [95% CI: 15%, 26%]) or overweight (24% [95% CI: 18%, 29%], p = 0.016). There were no significant changes in BMI from pre-treatment to 3-month follow-up, however there were significant reductions on the self-rated impact of weight on health.

CONCLUSIONS

Persons with chronic health conditions and with obesity or overweight benefit at least as much as those with a healthy BMI from iCBT programs targeting psychological adjustment to chronic illness, even without changes in BMI. iCBT programs may be an important component in the self-management of this population, and may address barriers implicated in health behaviour change.

Efficacy of an Online Workplace Mental Health Accommodations Psychoeducational Course: A Randomized Controlled Trial

Workplace accommodations can improve work functioning for employees with mental health concerns, yet few employees receive accommodations. The current study examined the benefits of providing education on workplace accommodations. In total, 89 participants with symptoms of depression and/or anxiety were randomized to an online psychoeducation course or wait-list control (WLC). The course provided education on symptoms, accommodations, tips for requesting accommodations and making disclosures, and coping strategies. Primary outcomes included the impact of the course on requesting and receiving accommodations, accommodation knowledge, self-stigma, and workplace relationships at 8 weeks post-randomization. Additional analyses examined the impact of the course on symptoms, absenteeism, presenteeism, and self-efficacy and whether supervisory leadership and organizational inclusivity impact disclosure and accommodation use. Participants in the course reported improvements in accommodation knowledge, self-efficacy, and presenteeism compared to the WLC. Both groups reported reduced self-stigma and increased disclosures over time. Specifically, partial disclosures were associated with supportive organizations and supervisors. No group differences were found on accommodation use, symptoms, workplace relationships, or comfort with disclosure. Few participants made accommodation requests, therefore a statistical analysis on requesting or receiving accommodations was not performed. Overall, providing psychoeducation has the potential to assist individuals with depression and anxiety who may require workplace accommodations, but further research is required.

Predictive models for clinical decision making: Deep dives in practical machine learning

The deployment of machine learning for tasks relevant to complementing standard of care and advancing tools for precision health has gained much attention in the clinical community, thus meriting further investigations into its broader use. In an introduction to predictive modelling using machine learning, we conducted a review of the recent literature that explains standard taxonomies, terminology and central concepts to a broad clinical readership. Articles aimed at readers with little or no prior experience of commonly used methods or typical workflows were summarised and key references are highlighted. Continual interdisciplinary developments in data science, biostatistics and epidemiology also motivated us to further discuss emerging topics in predictive and data-driven (hypothesis-less) analytics with machine learning. Through two methodological deep dives using examples from precision psychiatry and outcome prediction after lymphoma, we highlight how the use of, for example, natural language processing can outperform established clinical risk scores and aid dynamic prediction and adaptive care strategies. Such realistic and detailed examples allow for critical analysis of the importance of new technological advances in artificial intelligence for clinical decision-making. New clinical decision support systems can assist in prevention and care by leveraging precision medicine.

The Chronic Conditions Course: A Randomised Controlled Trial of an Internet-Delivered Transdiagnostic Psychological Intervention for People with Chronic Health Conditions

INTRODUCTION

Psychological adjustment to chronic health conditions is important, as poor adjustment predicts a range of adverse medical and psychosocial outcomes. Psychological treatments demonstrate efficacy for people with chronic health conditions, but existing research takes a disorder-specific approach and they are predominately delivered in face-to-face contexts. The internet and remotely delivered treatments have the potential to overcome barriers to accessing traditional face-to-face treatment.

OBJECTIVE

The current study examined the efficacy and acceptability of an internet-delivered transdiagnostic psychological intervention to promote adjustment to illness, based on cognitive behaviour therapy principles.

METHODS

In a two-arm randomised controlled trial, participants (n = 676) were randomly allocated to the 8-week intervention or a waitlist control. Treatment included five core lessons, homework tasks, additional resources, and weekly contact with a psychologist. Primary outcomes included depression, anxiety, and disability, assessed at pre-treatment, post-treatment, 3-month follow-up, and 12-month follow-up.

RESULTS

The treatment group reported significantly greater improvements in depression (between-groups d = 0.47), anxiety (d = 0.32), and disability (d = 0.17) at post-treatment (all ps <0.001). Improvements were sustained over the 3-month and 12-month follow-ups. High treatment completion rates (69%) and levels of satisfaction (86%) were reported by participants in treatment. The intervention required a mean clinician time of 56.70 min per participant.

CONCLUSIONS

The findings provide preliminary and tentative support for the potential of internet-delivered transdiagnostic interventions to promote adjustment to chronic health conditions. Further research using robust control groups, and exploring the generalisability of findings, is needed before firm conclusions can be drawn.

Antidepressant medication use by patients accessing a national digital mental health service

BACKGROUND

Digital mental health services (DMHSs) provide psychological treatments via the internet or phone and are increasingly being offered as part of routine care. This study describes antidepressant (AD) medication use and treatment outcomes in a large sample of routine care patients accessing a DMHS.

METHODS

Patients completing an assessment with an Australia-wide DMHS (MindSpot Clinic) from 1st January to 31st December 2020 (n = 17,409) were asked about psychotropic medication use. Demographic characteristics and treatment outcomes on the PHQ-9 (depression), GAD-7 (anxiety), and K-10+ (general distress) were compared for patients taking an AD versus no AD. Treatment outcomes were also analyzed for a subgroup of patients reporting recent commencement of AD medication.

RESULTS

Almost one quarter of patients (4141/17409; 23.8%) reported taking an AD, mainly selective serotonin reuptake inhibitors (SSRIs). Patients taking ADs had more severe symptoms however effect sizes were large (Cohen's d's > 1.0). Patients recently commencing ADs had the highest baseline symptoms but showed greater symptom improvement at post-treatment and 3-month follow-up.

LIMITATIONS

Treatment trajectory was measured weekly using standardized scales that are sensitive to change, however they did not allow formal clinical diagnoses of depression and were subject to the effects of missing data. The observational design did not control for spontaneous recovery or for comorbid conditions that might influence recovery.

CONCLUSIONS

Despite these limitations, online treatment provided by a DMHS as part of routine care is acceptable and effective for patients reporting concurrent AD medication use.

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.

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 Comparison of Self-Referral and Referral via Primary Care Providers, through Two Similar Digital Mental Health Services in Western Australia

Digital mental health services (DMHSs) deliver mental health information, assessment, and treatment, via the internet, telephone, or other digital channels. The current study compares two DMHSs operating in Western Australia (WA)-The Practitioner Online Referral System (PORTS) and MindSpot. Both provide telephone and online psychological services at no cost to patients or referrers. However, PORTS is accessed by patients via referral from health practitioners, and is designed to reach those who are financially, geographically, or otherwise disadvantaged. In contrast, MindSpot services are available to all Australian residents and patients can self-refer. This observational study compares characteristics and treatment outcomes for patients of PORTS and MindSpot in WA. Eligible patients were people who resided in WA and registered with either clinic from January 2019 to December 2020. Results showed that PORTS patients were more likely to be older, male, and unemployed. They were less likely to report a tertiary education and were more likely to live in areas with higher levels of socioeconomic disadvantage. Despite these differences, treatment outcomes were excellent for patients from both clinics. Results provide further evidence for the accessibility, acceptability, and effectiveness of DMHSs regardless of referral pathway or patient characteristics.

The Pain Course: a randomised controlled trial and economic evaluation of an internet-delivered pain management program

ABSTRACT

There is interest in the potential of Internet-delivered programs to cost-effectively increase access to pain management for people with chronic pain. However, few large-scale clinical and economic evaluations have been undertaken. Using a randomised controlled trial design, the current study (n = 659) examined the clinical efficacy, cost-effectiveness, and cost utility of an Internet-delivered pain management program for people with mixed chronic pain conditions when delivered with optional clinician support. The treatment group reported significant improvements in disability, depression, anxiety, average pain intensity, and quality-adjusted life years (QALYs), compared with control, and exhibited relatively high levels of treatment engagement and satisfaction. Each additional clinical improvement (defined as ≥ 30% improvement) produced by the intervention, over control, was associated with a cost of $48, $27, $38, and $83 for disability, depression, anxiety, and average pain intensity, respectively. Gaining one QALY was associated with a cost of $152 or $11,910 per QALY when an 80% probability criterion for cost utility was applied. The program itself was associated a relatively small, fixed, cost per patient but was not cost saving over the brief intervention period. The findings support the clinical efficacy and cost-effectiveness of Internet-delivered programs with "on demand" clinician support as a way to increase access to pain management. Key limitations of the current study include the use of a waitlist-control group, a short follow-up period, and the focus on governmental healthcare costs. Further evaluation of these programs is necessary if they are scaled up and offered as routine care.

Evaluation of a Commercial Mobile Health App for Depression and Anxiety (AbleTo Digital+): Retrospective Cohort Study

BACKGROUND

Digital solutions, such as web-based and mobile interventions, have the potential to streamline pathways to mental health services and improve access to mental health care. Although a growing number of randomized trials have established the efficacy of digital interventions for common mental health problems, less is known about the real-world impact of these tools. AbleTo Digital+, a commercially available mental health app for depression and anxiety, offers a unique opportunity to understand the clinical impact of such tools delivered in a real-world context.

OBJECTIVE

The primary aim of this study is to examine the magnitude of change in depression and anxiety symptoms among individuals who used AbleTo Digital+ programs. The secondary aim is to evaluate Digital+ module completion, including the use of 1:1 coaching.

METHODS

In this retrospective cohort study, we analyzed previously collected and permanently deidentified data from a consecutive cohort of 1896 adults who initiated using one of the three Digital+ eight-module programs (depression, generalized anxiety, or social anxiety) between January 1 and June 30, 2020. Depression, generalized anxiety, and social anxiety symptoms were assessed within each program using the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, and the Social Phobia Inventory, respectively. Linear mixed effects models were built to assess the association between module completion and symptom change among users who completed at least four modules and had at least mild baseline symptom elevations, controlling for age, gender, and baseline symptom severity. Digital+ use, including module completion, 1:1 coaching calls, and in-app coach messaging, was also evaluated.

RESULTS

Significant effects were observed among depression (Cohen d=1.5), generalized anxiety (Cohen d=1.2), and social anxiety (Cohen d=1.0) program participants who completed at least four modules and had mild baseline elevations (n=470). Associations between module completion and change in depression (β=-1.2; P<.001), generalized anxiety (β=-1.1; P<.001), and social anxiety (β=-2.4; P<.001) symptom scores retained significance with covariate adjustment. Participants completed an average of 2.6 (SD 2.7) modules. The average total length of app use was 52.2 (SD 83.5) days. Approximately two-thirds of the users engaged in at least 1 coaching call (66.82%, 1267/1896) or in-app text messaging (66.09%, 1253/1896). Participants who completed at least four modules participated in significantly more coaching calls per module (mean 1.1, SD 0.7) than users who completed fewer than four modules (mean 1.0, SD 1.2; t1407=-2.1; P=.03).

CONCLUSIONS

This study demonstrated that AbleTo Digital+ users experienced significant reductions in depression, generalized anxiety, and social anxiety symptoms throughout the program.

Internet-delivered cognitive-behaviour therapy (ICBT) for obsessive-compulsive disorder when delivered as routine clinical care: A phase IV clinical trial

Cognitive-behaviour therapy (CBT) is an effective treatment for obsessive-compulsive disorder (OCD), but many patients experience difficulty accessing this treatment. Internet-delivered CBT (ICBT) enhances access to CBT for individuals with OCD and has been shown to be efficacious in Phase I, II, and III clinical trials. However, there are fewer studies investigating ICBT for OCD in Phase IV clinical trials, which demonstrate the effectiveness of the intervention when provided as part of routine care. The aim of the present study was to report on the effectiveness of ICBT for OCD, using data from Australia's MindSpot Clinic, a federally funded treatment service that provides free ICBT to Australian adults with anxiety, depression, and pain conditions. A total of 225 MindSpot users (68 % female; Mage = 34.82; SD = 11.02) were included in the study. Within-group effect sizes at post-treatment on the Yale-Brown Obsessive-Compulsive Scale, indicated medium effect sizes (g = 0.6; 95 % CI: 0.5-0.7), increasing to large effects at three-month follow up (g = 0.9; 95 % CI: 0.8-1.0). Effects on secondary outcome measures including measures of depression, generalized anxiety, and psychological distress ranged from (g = 0.5-0.6) at post-treatment and (g = 0.5-0.7) at three-month follow up. Results from benchmarking analyses indicated that the results from routine care were significantly smaller than those found in a recent clinical trial using the same treatment protocol. The results indicate that ICBT delivered in real world settings is associated with meaningful improvements in OCD symptoms, however future research may wish to examine which patients respond best to this treatment approach and how to enhance outcomes.

Initial Outcomes of Transdiagnostic Internet-Delivered Cognitive Behavioral Therapy Tailored to Public Safety Personnel: Longitudinal Observational Study

Background

Canadian public safety personnel (PSP) experience high rates of mental health disorders and face many barriers to treatment. Internet-delivered cognitive behavioral therapy (ICBT) overcomes many such barriers, and is effective for treating depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms.

Objective

This study was designed to fill a gap in the literature regarding the use of ICBT tailored specifically for PSP. We examined the effectiveness of a tailored ICBT program for treating depression, anxiety, and PTSD symptoms among PSP in the province of Saskatchewan.

Methods

We employed a longitudinal single-group open-trial design (N=83) with outcome measures administered at screening and at 8 weeks posttreatment. Data were collected between December 5, 2019 and September 11, 2020. Primary outcomes included changes in depression, anxiety, and PTSD symptoms. Secondary outcomes included changes in functional impairment; symptoms of panic, social anxiety, and anger; as well as treatment satisfaction, working alliance, and program usage patterns.

Results

Clients reported large symptom reductions on measures of depression and anxiety, as well as moderate reductions on measures of PTSD and secondary symptoms, except for social anxiety. Most clients who reported symptoms above clinical cut-offs on measures of depression, anxiety, and PTSD during screening experienced clinically significant symptom reductions. Results suggested good engagement, treatment satisfaction, and working alliance.

Conclusions

Tailored, transdiagnostic ICBT demonstrated promising outcomes as a treatment for depression, anxiety, and PTSD among Saskatchewan PSP and warrants further investigation.

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.

Predictors, Outcomes, and Statistical Solutions of Missing Cases in Web-Based Psychotherapy: Methodological Replication and Elaboration Study

BACKGROUND

Missing cases present a challenge to our ability to evaluate the effects of web-based psychotherapy trials. As missing cases are often lost to follow-up, less is known about their characteristics, their likely clinical outcomes, or the likely effect of the treatment being trialed.

OBJECTIVE

The aim of this study is to explore the characteristics of missing cases, their likely treatment outcomes, and the ability of different statistical models to approximate missing posttreatment data.

METHODS

A sample of internet-delivered cognitive behavioral therapy participants in routine care (n=6701, with 36.26% missing cases at posttreatment) was used to identify predictors of dropping out of treatment and predictors that moderated clinical outcomes, such as symptoms of psychological distress, anxiety, and depression. These variables were then incorporated into a range of statistical models that approximated replacement outcomes for missing cases, and the results were compared using sensitivity and cross-validation analyses.

RESULTS

Treatment adherence, as measured by the rate of progress of an individual through the treatment modules, and higher pretreatment symptom scores were identified as the dominant predictors of missing cases probability (Nagelkerke R²=60.8%) and the rate of symptom change. Low treatment adherence, in particular, was associated with increased odds of presenting as missing cases during posttreatment assessment (eg, odds ratio 161.1:1) and, at the same time, attenuated the rate of symptom change across anxiety (up to 28% of the total symptom with 48% reduction effect), depression (up to 41% of the total with 48% symptom reduction effect), and psychological distress symptom outcomes (up to 52% of the total with 37% symptom reduction effect) at the end of the 8-week window. Reflecting this pattern of results, statistical replacement methods that overlooked the features of treatment adherence and baseline severity underestimated missing case symptom outcomes by as much as 39% at posttreatment.

CONCLUSIONS

The treatment outcomes of the cases that were missing at posttreatment were distinct from those of the remaining observed sample. Thus, overlooking the features of missing cases is likely to result in an inaccurate estimate of the effect of treatment.

Predicting outcome of daycare cognitive behavioural therapy in a naturalistic sample of patients with PTSD: a machine learning approach

BACKGROUND

Identifying predictors for treatment outcome in patients with posttraumatic stress disorder (PTSD) is important in order to provide an effective treatment, but robust and replicated treatment outcome predictors are not available up to now.

OBJECTIVES

We investigated predictors of treatment outcome in a naturalistic sample of patients with PTSD admitted to an 8-week daycare cognitive behavioural therapy programme following a wide range of traumatic events.

METHOD

We used machine learning (linear and non-linear regressors and cross-validation) to predict outcome at discharge for 116 patients and sustained treatment effects 6 months after discharge for 52 patients who had a follow-up assessment. Predictions were based on a wide selection of demographic and clinical assessments including age, gender, comorbid psychiatric disorders, trauma history, posttraumatic symptoms, posttraumatic cognitions, depressive symptoms, general psychopathology and psychosocial functioning.

RESULTS

We found that demographic and clinical variables significantly, but only modestly predicted PTSD treatment outcome at discharge (r = 0.21, p = .021 for the best model) and follow-up (r = 0.31, p = .026). Among the included variables, more severe posttraumatic cognitions were negatively associated with treatment outcome. Early response in PTSD symptomatology (percentage change of symptom scores after 4 weeks of treatment) allowed more accurate predictions of outcome at discharge (r = 0.56, p < .001) and follow-up (r = 0.43, p = .001).

CONCLUSION

Our results underscore the importance of early treatment response for short- and long-term treatment success. Nevertheless, it remains an unresolved challenge to identify variables that can robustly predict outcome before the initiation of treatment.

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.

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.

A Cost-effectiveness Analysis of an Internet-delivered Pain Management Program Delivered With Different Levels of Clinician Support: Results From a Randomised Controlled Trial

There is growing interest in the potential of internet-delivered pain management programs (PMPs) to increase access to care for people with chronic pain. However, very few economic evaluations of these interventions have been reported. Using existing data, the current study examined the cost-effectiveness of an internet-delivered PMP for a mixed group chronic pain patients (n = 490) provided with different levels of clinician support. The findings indicated that each additional clinical outcome (defined as a ≥ 30% reduction in disability, depression, anxiety, and pain) was associated with cost-savings when the intervention was provided in a self-guided format (ICER range: -$404--$808 AUD) or an optional-guided format (ICER range: -$314--$541 AUD), and a relatively small fixed cost when provided in the clinician-guided format (ICER range: $88-$225 AUD). The results were driven by a reduction in service use costs among the treatment groups, which offset the costs of providing the internet-delivered PMP in the self-guided and optional-guided formats. The same general pattern of results was found when more stringent clinical outcomes (defined as a ≥ 50% reduction) were employed. These findings suggest that carefully developed and administered internet-delivered PMPs, provided with different levels of clinician support, can be highly cost effective for patients with a broad range of pain conditions. PERSPECTIVE: This study examines the cost-effectiveness of an internet-delivered PMP provided to adults with a broad range of chronic pain conditions. Evidence of cost-effectiveness was found across a broad range of clinical outcomes and with different levels of clinician support.

User characteristics and outcomes from a national digital mental health service: an observational study of registrants of the Australian MindSpot Clinic

Background

Interest is growing in digital and telehealth delivery of mental health services, but data are scarce on outcomes in routine care. The federally funded Australian MindSpot Clinic provides online and telephone psychological assessment and treatment services to Australian adults. We aimed to summarise demographic characteristics and treatment outcomes of patients registered with MindSpot over the first 7 years of clinic operation.

Methods

We used an observational design to review all patients who registered for assessment with the MindSpot Clinic between Jan 1, 2013, and Dec 31, 2019. We descriptively analysed the demographics, service preferences, and baseline symptoms of patients. Among patients enrolled in a digital treatment course, we evaluated scales of depression (Patient Health Questionnaire-9 [PHQ-9]) and anxiety (Generalized Anxiety Disorder 7-Item Scale [GAD-7]), as primary measures of treatment outcome, from the screening assessment to post-treatment and a 3 month follow-up. The Kessler Psychological Distress 10-Item Plus Scale was also used to assess changes in general distress and disability, and course satisfaction was measured post-treatment.

Outcomes

A total of 121 652 screening assessments were started, of which 96 018 (78·9%) were completed. The mean age of patients was 35·7 years (SD 13·8) and 88 702 (72·9%) were women. Based on available assessment data, 36 866 (34·5%) of 106 811 participants had never previously spoken to a health professional about their symptoms, and most people self-reported symptoms of anxiety (88 879 [81·9%] of 108 494) or depression (78 803 [72·6%] of 108 494), either alone or in combination, at baseline. 21 745 patients started treatment in a therapist-guided online course, of whom 14 503 (66·7%) completed treatment (≥four of five lessons). Key trends in service use included an increase in the proportion of people using MindSpot primarily for assessment and information, from 52·6% in 2013 to 66·7% in 2019, while the proportion primarily seeking online treatment decreased, from 42·6% in 2013 to 26·7% in 2019. Effect sizes and percentage changes were large for estimated mean scores on the PHQ-9 and GAD-7 from assessment to post-treatment (PHQ-9, Cohen's d effect size 1·40 [95% CI 1·37–1·43]; and GAD-7, 1·45 [1·42–1·47]) and the 3 month follow-up (PHQ-9, 1·36 [1·34–1·38]; and GAD-7, 1·42 [1·40–1·44]); proportions of patients with reliable symptom deterioration (score increase of ≥6 points [PHQ-9] or ≥5 points [GAD-7]) were low post-treatment (of 13 058 respondents, 184 [1·4%] had symptom deterioration on the PHQ-9 and 282 [2·2%] on the GAD-7); and patient satisfaction rates were high (12 452 [96·6%] of 12 895 respondents would recommend the course and 12 433 [96·7%] of 12 860 reported the course worthwhile). We also observed small improvements in disability following treatment as measured by days out of role.

Interpretation

Our findings indicate improvement in psychological symptoms and positive reception among patients receiving online mental health treatment. These results support the addition of digital services such as MindSpot as a component in contemporary national mental health systems.

Internet-based self-help intervention aimed at increasing social self-efficacy among internal migrants in Poland: Study protocol for a randomized controlled trial

BACKGROUND

Migration is a challenging life transition that may be a source of various problems related to well-being and mental health. However, the psychological adaptation of migrants may be potentially facilitated by social self-efficacy-the beliefs in one's ability to initiate and maintain interpersonal relationships. Previous research suggests that social self-efficacy is positively related to adjustment and negatively related to loneliness, depression, and psychological distress. Research also confirms that self-efficacy beliefs can be effectively enhanced using Internet-based interventions. These results served as a background for creating the New in Town, a self-help Internet-based intervention for internal migrants in Poland that aims at increasing social self-efficacy. Exercises in the intervention are based on the principles of Cognitive Behavioral Therapy and relate to sources of self-efficacy beliefs: mastery experiences, vicarious experiences, verbal persuasions, and emotional and physiological states. Users complete increasingly challenging tasks that encourage them to interact with their environment. The aim of this trial was to investigate the efficacy of the New in Town intervention.

METHODS

The efficacy of the New in Town intervention will be tested in a two-arm randomized controlled trial with a waitlist control group. Social self-efficacy will be the primary outcome. Secondary outcomes will include loneliness, perceived social support, and satisfaction with life. Additionally, we will measure user experience among participants allocated to the experimental group. We aim to recruit a total of N = 280 participants aged at least 18 years who have changed their place of residence in the last 6 months and have an Internet connection. Participants will be assessed at baseline, 3-week post-test, and 8-week follow-up.

DISCUSSION

The trial will provide insights into the efficacy of Internet-based self-help interventions in increasing social self-efficacy. Given that the intervention works, New in Town could provide an easily accessible support option for internal migrants in Poland.

TRIAL REGISTRATION

The trial was registered with ClinicalTrials.gov (identifier: NCT04088487) on 11th September 2019.

Immediate and long-term effectiveness of adding an Internet intervention for depression to routine outpatient psychotherapy: Subgroup analysis of the EVIDENT trial

OBJECTIVE

To examine immediate and long-term effectiveness of an adjunctive Internet intervention for depression in a large sample of patients undergoing routine psychotherapy.

METHOD

The current study evaluated a subgroup of patients from the Evident trial, a randomized investigation of a 12-week minimally guided Internet intervention (Deprexis) for the treatment of mild to moderate depression. 340 adults (mean age = 43.3 years; 71.7 % female) of the original sample received routine outpatient psychotherapy during the trial period, resulting in a standard psychotherapy group (n = 174) and an augmented therapy group (n = 166). Outcomes were assessed at baseline, post-treatment and 6-month follow-up.

RESULTS

Intention-to-treat analyses indicated that combined treatment led to a greater reduction in symptoms of depression (effect size d = 0.32; p = .002), improved therapeutic progress (d = 0.36; p = .003), and higher mental health-related quality of life (d = 0.34; p = .004). There was no intervention effect on physical health-related quality of life. The same pattern was found at 6-month follow-up, and adjunctive treatment also resulted in increased rates of clinical improvement. Treatment success was independent from therapeutic orientation of combined face-to-face therapy.

CONCLUSION

Results indicate that the adjunctive use of the investigated intervention can produce additional and lasting effects in routine outpatient psychotherapy for mild to moderate levels of depression. The study adds to the ongoing evidence on augmented effects of blended treatment. Future studies should investigate different types of blends in diverse populations by means of change-sensitive assessment strategies.

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.

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.

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.

Self-guided internet-delivered cognitive behavior therapy (ICBT) for obsessive-compulsive symptoms: A randomized controlled trial

Internet-delivered cognitive behavior therapy (ICBT) for obsessive-compulsive disorder (OCD) has been demonstrated to be efficacious across multiple clinical trials. However, most of these interventions include clinician support, and many individuals with OCD prefer to manage their own symptoms. Self-guided ICBT overcomes this problem, but to date the efficacy of self-guided interventions has only been studied in uncontrolled trials. The present study aims to examine the efficacy and acceptability of ICBT for OCD symptoms when delivered in a self-guided format using a randomized controlled trial design. In the present study, 190 participants were randomized to either a self-guided ICBT condition or a waitlist control group. 140 participants completed the baseline assessment, initiated treatment, and were included in the analyses. The between-group effect size at post-treatment was large on the self-report version of the Yale-Brown Obsessive-Compulsive Scale (d = 1.05; 95% CI 0.89-1.21). Twenty-seven percent of the ICBT condition met conservative criteria for clinically significant change at post-treatment, which increased to thirty-eight percent at three-month follow-up. Participants rated the program as highly acceptable. The results indicate that self-guided ICBT may be a viable treatment option for some individuals with OCD symptoms.

Transdiagnostic, internet-delivered cognitive behavior therapy for depression and anxiety: Exploring impact on health anxiety

Health anxiety is associated with significant personal distress and economic cost; as such, widely available and effective treatment options are crucial. Several studies suggest that Internet-delivered cognitive behavior therapy (ICBT) programs that specifically target health anxiety are efficacious for this condition. However, no known studies have examined the impact of transdiagnostic ICBT, which emphasizes the acquisition of broad coping skills applicable to a variety of mental health concerns, on symptoms of health anxiety. The current study sought to explore changes in health anxiety symptoms by utilizing data available from a previously published study of 8-week transdiagnostic ICBT. Specifically, changes in symptoms of health anxiety in response to a transdiagnostic ICBT program that targeted broad symptoms of depression and anxiety, were examined in a subsample of individuals who endorsed elevated symptom scores on the Short Health Anxiety Inventory at pre-treatment (n = 72). Following treatment, large reductions in health anxiety symptoms (Cohen's d = 0.91; 20% improvement), depression (Cohen's d = 0.85; reduction = 38%), generalized anxiety (Cohen's d = 1.21; reduction = 42%), and disability (Cohen's d = 0.90; reduction = 35%) were reported. Furthermore, results showed that transdiagnostic ICBT was rated as acceptable to people with high health anxiety symptoms. Despite elevated pre-treatment health anxiety scores, email correspondence between clients and their therapist revealed very few mentions of health anxiety. These findings provide preliminary evidence for transdiagnostic ICBT for symptoms of health anxiety and suggest further research is warranted.

The Pain Course: 12- and 24-Month Outcomes From a Randomized Controlled Trial of an Internet-Delivered Pain Management Program Provided With Different Levels of Clinician Support

Little is known about the long-term outcomes of emerging Internet-delivered pain management programs. The current study reports the 12- and 24-month follow-up data from a randomized controlled trial (n = 490) of an Internet-delivered pain management program, the Pain Course. The initial results of the trial to the 3-month follow-up have been reported elsewhere. There were significant improvements in disability, depression, anxiety, and pain levels across 3 treatment groups receiving different levels of clinician support compared with a treatment as the usual control. No marked or significant differences were found between the treatment groups either after treatment or at the 3-month follow-up. The current study obtained long-term follow-up data from 78% and 79% of participants (n = 397) at the 12-month and 24-month follow-up marks, respectively. Clinically significant decreases (average percent reduction; Cohen's d effect sizes) were maintained at the 12- and 24-month follow-ups for disability (average reduction ≥27%; d ≥ .67), depression (average reduction ≥36%; d ≥ .80), anxiety (average reduction ≥38%; d ≥ .66), and average pain levels (average reduction ≥21%; d ≥ .67). No marked or consistent differences were found among the 3 treatment groups. These findings suggest that the outcomes of Internet-delivered programs may be maintained over the long term. PERSPECTIVE: This article presents the long-term outcome data of an established Internet-delivered pain management program for adults with chronic pain. The clinical improvements observed during the program were found to be maintained at the 12- and 24-month follow-up marks. This finding indicates that these programs can have lasting clinical effects.
