The impact of guidance on Internet-based mental health interventions — A systematic review

Foot thermometry with mHeath-based supplementation to prevent diabetic foot ulcers: A randomized controlled trial

Background: Three previous clinical trials have found that thermometry use reduced diabetic foot ulcers (DFUs) incidence four- to ten-fold among individuals with diabetes at high-risk of developing a DFU. However, these benefits depend on patient adherence to self-assessment. Therefore, novel approaches to improve self-management thermometry adherence are needed. Our objective was to compare incidence of DFUs in the thermometry plus mobile health (mHealth) reminders intervention arm vs. thermometry-only control arm. Methods: We conducted a randomized trial, enrolling adults with type 2 diabetes mellitus at risk of foot ulcers (risk groups 2 or 3) but without foot ulcers at the time of recruitment and allocating them to control (instruction to use a liquid crystal-based foot thermometer daily) or intervention (same instruction supplemented with text and voice messages with reminders to use the device and messages to promote foot care) groups and followed for 18 months. The primary outcome was time to occurrence of DFU. A process evaluation was also conducted. Results: A total of 172 patients (63% women, mean age 61 years) were enrolled; 86 to each study group. More patients enrolled in the intervention arm had a history of DFU (66% vs. 48%). Follow-up for the primary endpoint was complete for 158 of 172 participants (92%). DFU cumulative incidence was 24% (19 of 79) in the intervention arm and 11% (9 of 79) in the control arm. After adjusting for history of foot ulceration and study site, the Hazard Ratio (HR) for DFU was 1.44 (95% CI 0.65, 3.22). Adherence to ≥80% of daily temperature measurements was 87% (103 of 118) among the study participants who returned the logbook, with no difference between the intervention and control arms. Conclusions: This trial contributes to the evidence about the value of mHealth in preventing diabetes foot ulcers. Trial registration: ClinicalTrials.gov NCT02373592 (27/02/2015).

Digitale Behandlungsangebote für Insomnie – eine Übersichtsarbeit

Digital angebotene psychologische Interventionen gegen Schlafstörungen sind aktuell ein sehr intensiv bearbeitetes Forschungsthema. In dieser Übersichtsarbeit werden Originalarbeiten und Metaanalysen zu diesem Thema zusammengefasst. Hierbei zeigt sich, dass die internetbasierte kognitive Verhaltenstherapie für Insomnie (KVT-I) bei Erwachsenen durchweg sehr effektiv ist mit allenfalls leicht geringeren Effektstärken als die gleiche Behandlung mit physischer Präsenz von Therapeuten und Patienten. Behandlungseffekte zeigen sich dabei auch für sekundäre Outcome-Parameter wie Depressivität, Angst, Fatigue und Lebensqualität. Hingegen lassen die Forschung zur Wirksamkeit der internetbasierten KVT‑I bei Erwachsenen mit komorbiden psychischen Störungen oder körperlichen Erkrankungen sowie die Forschung zur Frage, wieviel Therapeutenkontakt in die Behandlung integriert werden sollte, anscheinend noch keine abschließenden Antworten zu. In diesen Bereichen scheint weitere Forschung notwendig zu sein scheint.

Effectiveness of a tailored, integrative Internet intervention (deprexis) for depression: Updated meta-analysis

Digitally delivered interventions for depression vary in many aspects, including their therapeutic orientation, depth of content, interactivity, individual tailoring, inclusion of multimedia, cost, and effectiveness. However, their effectiveness is rarely examined in intervention-specific meta-analyses. An earlier meta-analysis of eight randomized controlled trials (RCT) demonstrated the effectiveness of a tailored, integrative digital intervention (deprexis), which is delivered via the Internet. This updated meta-analysis of twelve deprexis-specific RCT with a total of N = 2901 participants confirmed the effectiveness of deprexis for depression reduction at post-intervention (g = 0.51, 95% CI: 0.40-0.62, I2 = 26%). Results were analogous when study quality, screening and randomization procedure were taken into account. Clinician guidance, developer-involvement, setting (community vs. clinical), and initial symptom severity did not have statistically significant effects on the effect size, and there was no evidence of publication bias. Thus, these findings demonstrate that deprexis can facilitate clinically relevant reduction of depressive symptoms over 8-12 weeks across a broad range of initial symptom severity, and that the intervention can be combined with other forms of depression treatment. There is now a need to study the intervention's implementation in routine care settings as well as its long-term effectiveness and cost-effectiveness in diverse cultural and linguistic settings.

Efficacy of Self-Management Smartphone-Based Apps for Post-traumatic Stress Disorder Symptoms: A Systematic Review and Meta-Analysis

Post-traumatic stress disorder (PTSD) symptoms are prevalent in both civilian and military service members. As the number of smartphone-based applications (apps) grows rapidly in health care, apps are also increasingly used to help individuals with subthreshold PTSD or full PTSD. Yet, if the apps are self-managed, the feasibility and efficacy of such interventions are still rather unclear in these two populations with PTSD symptoms. Hence, the present meta-analysis set out to evaluate the effect of self-management smartphone-based apps on PTSD and depressive symptoms in populations with subthreshold PTSD or full PTSD. Studies were included if they conducted randomized controlled trials or pre-post comparisons. Six studies (n = 2 randomized controlled trials) were identified for meta-analysis. In pre-post comparisons, N = 209 participants were included in the analyses. In randomized controlled trials, N = 87 participants received smartphone-based self-management interventions and N = 82 participants were in waitlist control conditions. Meta-analysis for pre-post comparisons concluded an effect of g = 0.55 (p < 0.001) regarding the overall reduction in PTSD symptoms (n = 6) and g = 0.45 (p < 0.001) for reduction in depressive symptoms (n = 5). Yet, in randomized controlled trials, no significant difference was found between app-based treatment and waitlist control groups (g = 0.09, p = 0.574). The duration of the interventions did not significantly influence the results. Overall, despite positive pre-post effects, current results indicate that smartphone-apps for PTSD patients are not significantly more effective than waitlist control conditions. Nevertheless, a combined smartphone and standard therapy approach may be a fruitful field for future research.

Predictors of treatment outcomes and adherence in internet-based cognitive behavioral therapy for social anxiety in China

BACKGROUND

Although internet-based cognitive behaviour therapy (ICBT) is an effective treatment for social anxiety disorder (SAD), a substantial proportion of patients do not achieve clinically significant improvement. More research is needed to identify which factors predict treatment adherence and outcomes.

AIMS

The aims of this study were to (1) identify demographic and clinical factors associated with treatment adherence and outcomes in ICBT for social anxiety in China, and (2) explore whether low-intensity therapist support results in improved treatment adherence or outcomes.

METHOD

Participants were assigned to either therapist-guided (N = 183) or self-guided ICBT (N = 72). Level of social anxiety was measured at both pre- and post-treatment. Treatment adherence and outcomes were analysed using a two-step linear and logistic regression approach. Clinical and demographic characteristics were examined.

RESULTS

No significant group differences were found for treatment adherence or outcomes between the therapist-guided and self-guided conditions. Participants diagnosed with SAD were significantly less likely to drop out (OR 0.531, p = .03) compared with subclinical participants with social anxiety symptoms. Older participants (B = 0.17, SE = 0.04, p = .008) and participants with a diagnosis of SAD (B = 0.16, SE = 0.44, p = .01) tended to complete more modules. Participants who completed more modules (B = 0.24, SE = 0.03, p = .01) and participants who identified as female (B = -0.20, SE = 0.18, p = .04) reported greater reductions in SAD symptoms.

CONCLUSIONS

Understanding of factors related to adherence and outcome is necessary to prevent drop-out and optimize outcome.

Implementing complaint-directed mini-interventions for depressive complaints in primary care to increase participation among patients with a lower socioeconomic status: design of a cluster randomised controlled trial

BACKGROUND

Depression is a major public health concern. E-health interventions for preventing and reducing depressive complaints have proven to be effective, and have the potential to make (mental) health care more accessible and efficient. However, the reach of these interventions needs to be improved, especially among people with a lower socioeconomic status (SES). Stimulating and supporting implementation of e-health in primary care, and offering guidance from general practice nurses (GP nurses) may be important strategies to achieve this.

METHODS/DESIGN

The online 'Complaint Directed Mini-Interventions' (CDMIs) for stress, sleep and worry complaints, which were found to be (cost-)effective in a self-guided format, will be implemented in the primary care setting using a blended care format (i.e. combining e-health with face-to-face sessions) with minimal guidance provided by the GP nurse. The main aim is to evaluate whether a SES-sensitive implementation strategy improves the participation rate (i.e. reach) of lower-SES patients in the blended online CDMIs as compared to a regular implementation strategy in a cluster randomised controlled trial. Randomisation will occur at the level of the GP nurse, and 228 patients will be included in the study. The primary outcome is the participation rate (completing at least one face-to-face session and two online exercises) of the lower-SES target group. It is hypothesised that this percentage will be higher in the SES-sensitive group as compared to the regular group. Secondary objectives are to evaluate the implementation process, to monitor and evaluate psychological complaints (depression, sleep, stress, worry and anxiety) and well-being over time. Patient assessments will take place at baseline, 3 and 12 months post baseline.

DISCUSSION

This study should contribute to our knowledge of reaching the lower-SES groups with a brief and complaint-specific blended approach for depressive complaints in primary care. It should also further our knowledge on successful strategies to implement depression prevention in primary care.

Effectiveness and Cost-Effectiveness of a Self-Guided Internet Intervention for Social Anxiety Symptoms in a General Population Sample: Randomized Controlled Trial

Background

Many people are accessing digital self-help for mental health problems, often with little evidence of effectiveness. Social anxiety is one of the most common sources of mental distress in the population, and many people with symptoms do not seek help for what represents a significant public health problem.

Objective

This study aimed to evaluate the effectiveness of a self-guided cognitive behavioral internet intervention for people with social anxiety symptoms in the general population.

Methods

We conducted a two-group randomized controlled trial in England between May 11, 2016, and June 27, 2018. Adults with social anxiety symptoms who were not receiving treatment for social anxiety were recruited using online advertisements. All participants had unrestricted access to usual care and were randomized in a 1:1 ratio to either a Web-based unguided self-help intervention based on cognitive behavioral principles or a waiting list control group. All outcomes were collected through self-report online questionnaires. The primary outcome was the change in 17-item Social Phobia Inventory (SPIN-17) score from baseline to 6 weeks using a linear mixed-effect model that used data from all time points (6 weeks, 3 months, 6 months, and 12 months).

Results

A total of 2122 participants were randomized, and 6 were excluded from analyses because they were ineligible. Of the 2116 eligible randomized participants (mean age 37 years; 80.24%, 1698/2116 women), 70.13% (1484/2116) had follow-up data available for analysis, and 56.95% (1205/2116) had data on the primary outcome, although attrition was higher in the intervention arm. At 6 weeks, the mean (95% CI) adjusted difference in change in SPIN-17 score in the intervention group compared with control was −1.94 (−3.13 to −0.75; P=.001), a standardized mean difference effect size of 0.2. The improvement was maintained at 12 months. Given the high dropout rate, sensitivity analyses explored missing data assumptions, with results that were consistent with those of the primary analysis. The economic evaluation demonstrated cost-effectiveness with a small health status benefit and a reduction in health service utilization.

Conclusions

For people with social anxiety symptoms who are not receiving other forms of help, this study suggests that the use of an online self-help tool based on cognitive behavioral principles can provide a small improvement in social anxiety symptoms compared with no intervention, although dropout rates were high.

Efficacy of a Self-Help Web-Based Recovery Training in Improving Sleep in Workers: Randomized Controlled Trial in the General Working Population

BACKGROUND

Sleep complaints are among the most prevalent health concerns, especially among workers, which may lead to adverse effects on health and work. Internet-delivered cognitive behavioral therapy for insomnia (iCBT-I) offers the opportunity to deliver effective solutions on a large scale. The efficacy of iCBT-I for clinical samples has been demonstrated in recent meta-analyses, and there is evidence that iCBT-I is effective in the working population with severe sleep complaints. However, to date, there is limited evidence from randomized controlled trials that iCBT-I could also be an effective tool for universal prevention among the general working population regardless of symptom severity. Although increasing evidence suggests that negatively toned cognitive activity may be a key factor for the development and maintenance of insomnia, little is known about how iCBT-I improves sleep by reducing presleep cognitive activity.

OBJECTIVE

This study aimed to examine the efficacy of a self-help internet-delivered recovery training, based on principles of iCBT-I tailored to the work-life domain, among the general working population. General and work-related cognitive activities were investigated as potential mediators of the intervention's effect.

METHODS

A sample of 177 workers were randomized to receive either the iCBT-I (n=88) or controls (n=89). The intervention is a Web-based training consisting of six 1-week modules. As the training was self-help, participants received nothing but technical support via email. Web-based self-report assessments were scheduled at baseline, at 8 weeks, and at 6 months following randomization. The primary outcome was insomnia severity. Secondary outcomes included measures of mental health and work-related health and cognitive activity. In an exploratory analysis, general and work-related cognitive activities, measured as worry and work-related rumination, were investigated as mediators.

RESULTS

Analysis of the linear mixed effects model showed that, relative to controls, participants who received iCBT-I reported significantly lower insomnia severity scores at postintervention (between-group mean difference -4.36; 95% CI -5.59 to - 3.03; Cohen d=0.97) and at 6-month follow-up (between-group difference: -3.64; 95% CI -4.89 to -2.39; Cohen d=0.86). The overall test of group-by-time interaction was significant (P<.001). Significant differences, with small-to-large effect sizes, were also detected for cognitive activity and for mental and work-related health, but not for absenteeism. Mediation analysis demonstrated that work-related rumination (indirect effect: a₁b₁=-0.80; SE=0.34; 95% boot CI -1.59 to -0.25) and worry (indirect effect: a₂b₂=-0.37; SE=0.19; 95% boot CI -0.85 to -0.09) mediate the intervention's effect on sleep.

CONCLUSIONS

A self-help Web-based recovery training, grounded in the principles of iCBT-I, can be effective in the general working population, both short and long term. Work-related rumination may be a particularly crucial mediator of the intervention's effect, suggesting that tailoring interventions to the workplace, including components to reduce the work-related cognitive activity, might be important when designing recovery interventions for workers.

A Web- and Mobile App-Based Mental Health Promotion Intervention Comparing Email, Short Message Service, and Videoconferencing Support for a Healthy Cohort: Randomized Comparative Study

BACKGROUND

The rapid increase in mental health disorders has prompted a call for greater focus on mental health promotion and primary prevention. Web- and mobile app-based interventions present a scalable opportunity. Little is known about the influence of human support on the outcomes of these interventions.

OBJECTIVE

This study aimed to compare the influence of 3 modes of human support on the outcomes (ie, mental health, vitality, depression, anxiety, stress, life satisfaction, and flourishing) of a 10-week, Web- and mobile app-based, lifestyle-focused mental health promotion intervention among a healthy adult cohort.

METHODS

Participants were recruited voluntarily using a combination of online and offline advertising. They were randomized, unblinded into 3 groups differentiated by human support mode: Group 1 (n=201): standard-fully automated emails (S); Group 2 (n=202): standard plus personalized SMS (S+pSMS); and Group 3 (n=202): standard plus weekly videoconferencing support (S+VCS), hosted by 1 trained facilitator. Participants accessed the intervention, including the questionnaire, on a Web-based learning management system or through a mobile app. The questionnaire, administered at pre- and postintervention, contained self-reported measures of mental well-being, including the "mental health" and "vitality" subscales from the Short Form Health Survey-36, Depression Anxiety and Stress Scale-21, Diener Satisfaction With Life Scale (SWLS), and Diener Flourishing Scale.

RESULTS

Of 605 potential participants, 458 (S: n=157, S+pSMS: n=163, and S+VCS: n=138) entered the study by completing registration and the preintervention questionnaire. At post intervention, 320 out of 458 participants (69.9%; S: n=103, S+pSMS: n=114, and S+VCS: n=103) completed the questionnaire. Significant within-group improvements were recorded from pre- to postintervention in all groups and in every outcome measure (P≤.001). No significant between-group differences were observed for outcomes in any measure: mental health (P=.77), vitality (P=.65), depression (P=.93), anxiety (P=.25), stress (P.57), SWLS (P=.65), and Flourishing Scale (P=.99). Adherence was not significantly different between groups for mean videos watched (P=.42) and practical activity engagement (P=.71). Participation in videoconference support sessions (VCSSs) was low; 37 out of 103 (35.9%) participants did not attend any VCSSs, and only 19 out of 103 (18.4%) attended 7 or more out of 10 sessions. Stratification within the S+VCS group revealed that those who attended 7 or more VCSSs experienced significantly greater improvements in the domains of mental health (P=.006; d=0.71), vitality (P=.005; d=0.73), depression (P=.04; d=0.54), and life satisfaction (P=.046; d=0.50) compared with participants who attended less than 7.

CONCLUSIONS

A Web- and mobile app-based mental health promotion intervention enhanced domains of mental well-being among a healthy cohort, irrespective of human support. Low attendance at VCSSs hindered the ability to make meaningful between-group comparisons. Supplementing the intervention with VCSSs might improve outcomes when attendance is optimized.

Acceptability, Feasibility, and Efficacy Potential of a Multimodal Acceptance and Commitment Therapy Intervention to Address Psychosocial and Advance Care Planning Needs among Anxious and Depressed Adults with Metastatic Cancer

Background: Adults with metastatic cancer frequently report anxiety and depression symptoms, which may impact health behaviors such as advance care planning (ACP). Objective: The study leveraged acceptance and commitment therapy (ACT), an evidence-based approach for reducing distress and improving health behaviors, and adapted it into a multimodal intervention (M-ACT) designed to address the psychosocial and ACP needs of anxious and depressed adults with metastatic cancer. The study evaluated M-ACT's acceptability, feasibility, and efficacy potential. Design: The study was designed as a single-arm intervention development and pilot trial. Setting/Subjects: The trial enrolled 35 anxious or depressed adults with stage IV cancer in community oncology clinics, with a referred-to-enrolled rate of 69% and eligible-to-enrolled rate of 95%. Measurements: M-ACT alternated four in-person group sessions with three self-paced online sessions. Acceptability and feasibility were assessed through enrollment, attendance, and satisfaction ratings. Outcomes and theorized intervention mechanisms were evaluated at baseline, midintervention, postintervention, and two-month follow-up. Results: Participant feedback was used to refine the intervention. Of participants starting the intervention, 92% completed, reporting high satisfaction. One-quarter did not begin M-ACT due to health declines, moving, or death. Completers showed significant reductions in anxiety, depression, and fear of dying and increases in ACP and sense of life meaning. In this pilot, M-ACT showed no significant impact on pain interference. Increases in two of three mechanism measures predicted improvement on 80% of significant outcomes. Conclusions: The M-ACT intervention is feasible, acceptable, and shows potential for efficacy in community oncology settings; a randomized trial is warranted.

@myTabu-A Placebo Controlled Randomized Trial of a Guided Web-Based Intervention for Individuals Who Sexually Abused Children and Individuals Who Consumed Child Sexual Exploitation Material: A Clinical Study Protocol

Background: There is a high demand for evidence-based and cost-effective treatment concepts for convicted individuals who sexually abused children (ISAC) and individuals who consumed child sexual exploitation material (ICCSEM) under community supervision (CS). The @myTabu-consortium developed a guided web-based intervention for convicted ISAC and ICCSEM under CS consisting of six online modules targeting psychological meaningful risk factors. The study aims to evaluate the effectiveness of this guided web-based intervention in reducing dynamic risk factors and the risk to re-offend compared to a placebo condition. Furthermore, these dynamic risk factors are measured before and after every module to evaluate their individual effectiveness to reduce the respective risk factor as well as risk to re-offend. This clinical trial protocol describes the planned methods as well as the intervention concept. Methods: The methodological design is a placebo controlled randomized add-on trial (N = 582) with follow-ups at 8 points in time. The placebo condition controls for attention and expectation effects and comprises the same amount of modules with a comparable temporal effort as the experimental intervention. The trial is conducted as an add-on to community supervision as usually done. Primary outcomes are dynamic risk factors assessed by self-report risk assessment tools and officially recorded re-offenses. Discussion: To the best of our knowledge, the study is the first to compare the (cost-) effectiveness of a guided web-based intervention for convicted ISAC and ICCSEM under community supervision against a placebo condition. Methodological limitations (e.g., potential ceiling- or volunteers-effects) are discussed. Clinical Trial Registration: German Clinical Trial Register (DRKS 00021256).

Efficacy of Internet-Delivered Psychodynamic Therapy: Systematic Review and Meta-Analysis

Recent years have seen an increase of internet-delivered interventions based on psychodynamic treatment models. To test the efficacy of internet-delivered psychodynamic therapy (IPDT), we conducted a systematic review and meta-analysis of randomized controlled trials. Following literature searches, we identified seven studies meeting inclusion criteria. The total number of participants was 528 in the treatment group and 552 in the control conditions. We found small effects favoring IPDT compared to inactive control conditions for main outcomes (g = 0.44), depression (g = 0.46), anxiety (g = 0.20), and quality of life (g = 0.40). There was significant heterogeneity between studies for main outcomes and depression. Within-group effects ranged from Hedges's g = 0.32-0.99. The effects of IPDT were maintained or increased at follow-up. Study quality varied but was generally high. No indications of publication bias were found. In conclusion, IPDT is a promising treatment alternative, especially for depression, although the small number of studies limits the generalizability of the findings.

The Role of Learning Support and Chat-Sessions in Guided Internet-Based Cognitive Behavioral Therapy for Adolescents With Anxiety: A Factorial Design Study

BACKGROUND

Increased awareness of anxiety in adolescents emphasises the need for effective interventions. Internet-based cognitive behavioural therapy (ICBT) could be a resource-effective and evidence-based treatment option, but little is known about how to optimize ICBT or which factors boost outcomes. Recently, the role of knowledge in psychotherapy has received increased focus. Further, chat-sessions are of interest when trying to optimize ICBT for youths. This study aimed to evaluate the role of learning support and chat-sessions during ICBT for adolescent anxiety, using a factorial design.

METHOD

A total of 120 adolescents were randomised to one of four treatment groups, in a 2x2 design with two factors: with or without learning support and/or chat-sessions.

RESULTS

Anxiety and depressive symptoms were reduced (Beck Anxiety Inventory- BAI; Cohen's d =0.72; Beck Depression Inventory- BDI; d =0.97). There was a main effect of learning support on BAI (d =0.38), and learning support increased knowledge gain (d =0.42). There were no main effects or interactions related to the chat-sessions. Treatment effects were maintained at 6-months, but the added effect of learning support had by then vanished.

CONCLUSION

ICBT can be an effective alternative when treating adolescents with anxiety. Learning support could be of importance to enhance short-term treatment effects, and should be investigated further.

Internet-Based Cognitive Behavior Therapy for Loneliness: A Pilot Randomized Controlled Trial

Loneliness has been described as a common source of discomfort based on a subjective discrepancy between the actual and desired social situation. For some people this feeling may become a sustained state that is associated with a wide range of psychiatric and psychosocial problems. While there are few existing treatment protocols, interventions based on cognitive behavioral therapy (CBT) have shown positive effects. The current study investigated the efficacy of an 8-week internet-based treatment containing CBT components aimed at reducing feelings of loneliness. Seventy-three participants were recruited from the general public and randomly allocated to treatment or a wait-list control condition. Participants were assessed with standardized self-report measures of loneliness, depression, social anxiety, worry, and quality of life at pretreatment and posttreatment. Robust linear regression analysis of all randomized participants showed significant treatment effects on the primary outcome measure of loneliness (between group Cohen's d = 0.77), and on secondary outcomes measuring quality of life and social anxiety relative to control at postassessment. The results suggest the potential utility of internet-based CBT in alleviating loneliness but more research on the long-term effects and the mechanisms underlying the effects is needed.

Effects of a 6-Week Internet-Based Stress Management Program on Perceived Stress, Subjective Coping Skills, and Sleep Quality

Occupational stress management intervention programs are known to be effective in preventing stress-related health burden. Two essential mechanisms underlie this effect: (i) a reduction in perceived stress (e.g., via relaxation-oriented techniques), and (ii) an improvement in coping skills (e.g., via cognitive-behavioral interventions). While relaxation-oriented interventions are more frequently employed in occupational settings, cognitive-behavioral stress management interventions reveal stronger effects on stress-related outcomes. As an effective and economic strategy, the dissemination of stress management programs via the internet is soaring, but most internet-based programs focus on relaxation or reducing perceived stress. In the present study, we examined the effects of a self-guided, cognitive-behavioral 6-week Internet-Based Stress Management (IBSM) program on perceived stress, coping skills, emotional exhaustion, depressive symptoms, and sleep quality. The IBSM consists of six modules focusing on the improvement of stress management skills such as dealing with acute stress, building up resources, or reappraising stress-facilitating cognitions. The participants have to work through the content on a weekly basis, requiring about 30 min per week followed by a transfer task lasting another 30 min. Healthy employees reporting elevated stress were recruited over the Internet and then randomly assigned to the IBSM group or a waiting list control group. A total of 134 participants completed all assessments before and after the training or waiting period. The IBSM group reported lower subjective stress levels after the program than the control group. In addition, the IBSM group exhibited improved coping skills and better sleep quality. Emotional exhaustion was reduced in both groups, while depressive symptoms did not change. These results suggest that a brief, 6-week, cognitive-behavioral internet-based stress management program improves coping skills, sleep quality, and well-being, and reduces the perceived stress of employees. Our results might encourage large-scale studies on the long-term stability and clinical efficacy of internet-based programs.

Can Brief Email Guidance Enhance the Effects of an Internet Intervention for People with Problematic Alcohol Use? A Randomized Controlled Trial

Some research suggests that internet interventions aimed at people with problematic alcohol use are more effective when provided with guidance from a therapist or coach. Purpose/Objectives: This trial intended to compare the effects of a previously evaluated internet intervention for people with problematic alcohol use when delivered with or without brief email guidance. Methods: Using online advertising, 238 participants, 18 years or older, were recruited and randomized to receive access to the Internet intervention Alcohol Help Center with or without brief email guidance from a health educator. The guidance consisted of at least four structured, slightly individualized emails delivered during the first two weeks after randomization. Participants were followed up at 3 and 6 months. Results: Number of log-ins did not differ significantly between groups throughout the follow-up period. The follow-up rate at 6 months was 47.0%. Generalized estimating equations run on the primary (standard drinks in preceding week/heavy drinking days in preceding week) and secondary outcome variables (AUDIT, AUDIT-C, quality of life) revealed no significant differences between the interventions on any of the outcomes. Conclusions/Importance: The study does not provide support for any added benefits of providing brief guidance via email in an internet intervention for problem drinkers.

Current research on the therapeutic alliance in internet interventions and possible negative effects is also described. The review closes with lessons learned from the past decades of research on internet interventions along with possible implications and future directions.

Web-Based Bereavement Care: A Systematic Review and Meta-Analysis

BACKGROUND

Web-based interventions have been introduced as novel and effective treatments for mental disorders and, in recent years, specifically for the bereaved. However, a systematic summary of the effectiveness of online interventions for people experiencing bereavement is still missing.

OBJECTIVE

A systematic literature search was conducted by four reviewers who reviewed and meta-analytically summarized the evidence for web-based interventions for bereaved people.

METHODS

Systematic searches (PubMed, Web of Science, PsycInfo, PsycArticles, Medline, and CINAHL) resulted in seven randomized controlled trials (N = 1,257) that addressed adults having experienced bereavement using internet-based interventions. We used random effects models to summarize treatment effects for between-group comparisons (treatment vs. control at post) and stability over time (post vs. follow-up).

RESULTS

All web-based interventions were based on cognitive behavioral therapy (CBT). In comparison with control groups, the interventions showed moderate (g = .54) to large effects (g = .86) for symptoms of grief and posttraumatic stress disorder (PTSD), respectively. The effect for depression was small (g = .44). All effects were stable over time. A higher number of treatment sessions achieved higher effects for grief symptoms and more individual feedback increased effects for depression. Other moderators (i.e. dropout rate, time since loss, exposure) did not significantly reduce moderate degrees of heterogeneity between the studies.

LIMITATIONS

The number of includable studies was low in this review resulting to lower power for moderator analyses in particular.

CONCLUSIONS

Overall, the results of web-based bereavement interventions are promising, and its low-threshold approach might reduce barriers to bereavement care. Nonetheless, future research should further examine potential moderators and specific treatment components (e.g. exposure, feedback) and compare interventions with active controls.

Cultural Adaptation of Scalable Psychological Interventions: A New Conceptual Framework

The worldwide mental health treatment gap calls for scaling-up psychological interventions, which requires effective implementation in diverse cultural settings. Evidence from the field of global mental health and cultural clinical psychology indicates cultural variation in how symptoms of common mental disorders are expressed, and how culturally diverse groups explain the emergence of such symptoms. An increasing number of studies have examined to what extent cultural adaptation enhances the acceptability and effectiveness of psychological interventions among culturally diverse groups. To date, this evidence is inconclusive, and there is a lack of studies that dismantle the multiple types of modifications involved in cultural adaptation.

Based on empirical evidence from ethnopsychological studies, cultural adaptation research, and psychotherapy research, the present paper offers a new conceptual framework for cultural adaptation that lays the groundwork for future empirical research.

The cultural adaptation framework encompasses three elements: i) cultural concepts of distress; ii) treatment components; and iii) treatment delivery. These three elements have been discussed in literature but rarely tested in methodologically rigorous studies. Innovative research designs are needed to empirically test the relevance of these adaptation elements, to better understand the substantial modifications that enhance acceptability and effectiveness of psychological interventions.

Using a theory-driven approach and innovative experimental designs, research on cultural adaptation has the potential not only to make psychological treatments more accessible for culturally adverse groups, but also to further advance empirical research on the basic question about the “key ingredients” of psychotherapy.

The phenomenology of common mental disorders, as well as mind-body concepts, vary across cultures.

Cultural adaptation may enhance the acceptability and effectiveness of psychological interventions.

There is a lack of empirical evidence on the substantial modifications in cultural adaptation.

Theory-driven, experimental approaches are needed in cultural adaptation research.

Internet/smartphone-based applications for the treatment of tinnitus: a systematic review

INTRODUCTION

Most of the individuals suffering from tinnitus report of negative effects on their lives to the extent that clinical intervention is necessary. Although traditional tinnitus management has proven to be effective in treating tinnitus, there are a few drawbacks. The major drawback is the lack of professionals for the treatment of tinnitus, especially in remote areas. Considering the growing usage of the internet as a platform for availing treatment, there is a requirement for the development of applications in the health care sector. Recent search related to tinnitus treatment revealed that more than 200 applications are available online in the most popular platforms like Android and iOS. However, most of the applications for the treatment of tinnitus lack validation, and thus, there is a need for research on this ground.

METHOD

Five studies evaluating the efficacy of Internet/app delivered tinnitus treatments were identified. The treatment forms included were Tinnitus E-program, Mobile serious game, Tinnitus web-based sound therapy, and Tailor-made notch music therapy delivered through a smart phone.

RESULTS

Each study used a variety of standardized and validated questionnaires to measure the outcome of the treatment. The outcome measures were diverse, but both Internet/app-based and traditional methods like Tinnitus Retraining Therapy, Cognitive Behavioral Therapy, and Acceptance and Commitment Therapy had similar improvements in terms of tinnitus distress and quality of life.

CONCLUSION

It can be construed that the development of tinnitus treatment applications and web-based platforms will have a significant impact on the normal life of individuals with tinnitus.

Standalone smartphone apps for mental health-a systematic review and meta-analysis

While smartphone usage is ubiquitous, and the app market for smartphone apps targeted at mental health is growing rapidly, the evidence of standalone apps for treating mental health symptoms is still unclear. This meta-analysis investigated the efficacy of standalone smartphone apps for mental health. A comprehensive literature search was conducted in February 2018 on randomized controlled trials investigating the effects of standalone apps for mental health in adults with heightened symptom severity, compared to a control group. A random-effects model was employed. When insufficient comparisons were available, data was presented in a narrative synthesis. Outcomes included assessments of mental health disorder symptom severity specifically targeted at by the app. In total, 5945 records were identified and 165 full-text articles were screened for inclusion by two independent researchers. Nineteen trials with 3681 participants were included in the analysis: depression (k = 6), anxiety (k = 4), substance use (k = 5), self-injurious thoughts and behaviors (k = 4), PTSD (k = 2), and sleep problems (k = 2). Effects on depression (Hedges’ g = 0.33, 95%CI 0.10–0.57, P = 0.005, NNT = 5.43, I² = 59%) and on smoking behavior (g = 0.39, 95%CI 0.21–0.57, NNT = 4.59, P ≤ 0.001, I² = 0%) were significant. No significant pooled effects were found for anxiety, suicidal ideation, self-injury, or alcohol use (g = −0.14 to 0.18). Effect sizes for single trials ranged from g = −0.05 to 0.14 for PTSD and g = 0.72 to 0.84 for insomnia. Although some trials showed potential of apps targeting mental health symptoms, using smartphone apps as standalone psychological interventions cannot be recommended based on the current level of evidence.

Experiences of internet-delivered and work-focused cognitive behavioral therapy for stress: A qualitative study

INTRODUCTION

Stress is one of the major challenges of modern society, causing significant costs and personal problems. In the recent decade a growing body of research has provided support for the efficacy of internet interventions for stress. However, few studies have focused on how participants experience internet interventions for stress.

METHOD

The current study was a qualitative follow-up study of an internet-delivered and work-focused cognitive behavioral treatment for stress. The aim was to capture participants' experiences of the treatment and their views on effects on health and well-being. Participants were selected from a controlled study (n = 27), using a criterion-based sampling approach selecting those participants who had completed all treatment modules. Nine semi-structured interviews were held, and the material was analyzed using Thematic Analysis.

RESULTS

The results indicated that most of the participants experienced positive effects on their mental health and well-being in both life and at work. All participants emphasized the importance of having access to therapist support. In line with previous research, participants found the intervention to be extensive and demanding and expressed the need for extended treatment time and therapist support.

CONCLUSIONS

Considering the limitations of the present study, future research could examine the feasibility of reducing the length of each session, extending deadlines and increasing therapist support. This could improve treatment efficacy and further enhance utilization in the target population.

Sort of a nice distance: a qualitative study of the experiences of therapists working with internet-based treatment of problematic substance use

Background

Internet interventions have been developed and tested for several psychiatric and somatic conditions. Few people with substance use disorders receive treatment and many drug users say that they would prefer getting help from online tools. Internet interventions are effective for reducing alcohol and cannabis use. The aim of the current study is to understand differences between internet-based and face-to-face treatment of problematic substance use. The concept of alliance will be used as a theoretical frame for understanding differences between internet-based treatment and face-to-face treatment, as perceived by therapists.

Method

The study has a qualitative design and is based on 3 focus group interviews with 12 therapists working with internet-based treatment for alcohol or cannabis use problems within five different programs.

Results

The analysis revealed five themes in the differences between internet-based and face-to-face treatment: communication, anonymity, time, presence and focus. Treatment online in written and asynchronous form creates something qualitatively different from regular face-to-face meetings between patients and therapists. The written form changes the concept of time in treatment, that is, how time can be used and how it affects the therapist’s presence. The asynchronous (i.e. time delayed) form of communication and the lack of facial expressions and body language require special skills.

Conclusions

There are important differences between internet-based treatment and face-to-face treatment. Different aspects of the alliance seem to be important in internet-based treatment compared to face-to-face.

GET.HAPPY2 - User perspectives on an internet-based self-management positive psychology intervention among persons with and without depression: Results from a retrospective survey

OBJECTIVE

Previous research suggests that online positive psychology interventions (PPI) are frequently used by individuals with symptoms of depression. We aimed to investigate differences in the way depressed and nondepressed users react to the content of an existing online PPI, originally designed for the general public.

METHOD

In a retrospective online survey, we assessed discontinuation parameters, aspects of satisfaction with the program, and negative reactions among users of an online PPI.

RESULTS

Bivariate and multivariate analyses showed that, overall, reactions between depressed and nondepressed individuals were similar. Differences were observed concerning reasons for using and for discontinuing the program, the perception of exercises, and negative reactions.

CONCLUSIONS

Although satisfaction with the program was high, it did not seem to fully meet users' expectations and might be more difficult to complete during episodes of depression. Implications of this study for the adaptation of online PPIs addressing depressed individuals are discussed.

Intervention components, mediators, and mechanisms of change of Internet- and mobile-based interventions for post-traumatic stress disorder: protocol for a systematic review and meta-analysis

BACKGROUND

While Internet- and mobile-based interventions (IMIs) might possess the potential to increase access to evidence-based therapies for post-traumatic stress disorder (PTSD), comprehensive knowledge on active intervention components and change mechanisms underlying their efficacy is largely pending so far. The proposed systematic review and meta-analysis will systematically review the current status of research on the efficacy of IMIs for adult PTSD compared to active control conditions and identify active intervention components and mediators responsible for therapeutic change.

METHODS

A systematic literature search (PsycINFO, Medline/PubMed, Embase, CENTRAL, ICTRP, and Web of Science) will be conducted using keywords targeting "PTSD" and "Internet- and mobile-based interventions". Two independent researchers will retrieve studies eligible for inclusion and extract and evaluate data (design, population, outcomes, sample size, duration of intervention and follow-up, drop-out rate). Risk of bias will be assessed, and results will be synthesized qualitatively and evaluated meta-analytically when possible.

DISCUSSION

The results of this systematic review and meta-analysis might further contribute to the development of IMIs for PTSD by highlighting intervention components and mediators associated with their efficacy. Knowledge about the active ingredients might ultimately lead to more effective interventions and treatment packages, with implications for clinical practice and dissemination of these rather novel interventions.

Pilot study of a personality-based approach to assessing eating disorder and Obsessive Compulsive Disorder symptom risk in college men and women

Objective: To conduct a pilot test of the validity of using empirically derived personality types to characterize eating disorder (ED) risk in college students and resolve discrepancies regarding the role of perfectionism and obsessive-compulsive disorder (OCD) symptoms.Participants: Man and woman undergraduate students (N = 169) at a small, private university. Data were collected from February to May 2016 and 2018. Methods: Participants completed self-report measures of personality (perfectionism, impulsivity, and effortful control) and psychopathology (EDs, OCD). Results: Our analyses replicated three validated personality types: overcontrolled, undercontrolled, and resilient. Analysis of variances demonstrated perfectionism, ED, and OCD symptoms were significantly elevated in the overcontrolled subtype. There was no interaction by sex. Conclusions: These findings suggest that personality types may be useful for classifying ED risk and OCD symptoms in college students across sexes. Further study and relevance to prevention and intervention efforts to reduce the burden of EDs on college campuses will be discussed.

The Effectiveness of Web-Based Interventions Delivered to Children and Young People With Neurodevelopmental Disorders: Systematic Review and Meta-Analysis

BACKGROUND

The prevalence of certain neurodevelopmental disorders, specifically autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), has been increasing over the last four decades. Nonpharmacological interventions are available that can improve outcomes and reduce associated symptoms such as anxiety, but these are often difficult to access. Children and young people are using the internet and digital technology at higher rates than any other demographic, but although Web-based interventions have the potential to improve health outcomes in those with long-term conditions, no previous reviews have investigated the effectiveness of Web-based interventions delivered to children and young people with neurodevelopmental disorders.

OBJECTIVE

This study aimed to review the effectiveness of randomized controlled trials (RCTs) of Web-based interventions delivered to children and young people with neurodevelopmental disorders.

METHODS

Six databases and one trial register were searched in August and September 2018. RCTs were included if they were published in a peer-reviewed journal. Interventions were included if they (1) aimed to improve the diagnostic symptomology of the targeted neurodevelopmental disorder or associated psychological symptoms as measured by a valid and reliable outcome measure; (2) were delivered on the Web; (3) targeted a youth population (aged ≤18 years or reported a mean age of ≤18 years) with a diagnosis or suspected diagnosis of a neurodevelopmental disorder. Methodological quality was rated using the Joanna Briggs Institute Critical Appraisal Checklist for RCTs.

RESULTS

Of 5140 studies retrieved, 10 fulfilled the inclusion criteria. Half of the interventions were delivered to children and young people with ASDs with the other five targeting ADHD, tic disorder, dyscalculia, and specific learning disorder. In total, 6 of the 10 trials found that a Web-based intervention was effective in improving condition-specific outcomes or reducing comorbid psychological symptoms in children and young people. The 4 trials that failed to find an effect were all delivered by apps. The meta-analysis was conducted on five of the trials and did not show a significant effect, with a high level of heterogeneity detected (n=182 [33.4%, 182/545], 5 RCTs; pooled standardized mean difference=-0.39; 95% CI -0.98 to 0.20; Z=-1.29; P=.19 [I²=72%; P=.006]).

CONCLUSIONS

Web-based interventions can be effective in reducing symptoms in children and young people with neurodevelopmental disorders; however, caution should be taken when interpreting these findings owing to methodological limitations, the minimal number of papers retrieved, and small samples of included studies. Overall, the number of studies was small and mainly limited to ASD, thus restricting the generalizability of the findings.

Evaluating the Efficacy of Internet-Delivered Cognitive Behavioral Therapy Blended With Synchronous Chat Sessions to Treat Adolescent Depression: Randomized Controlled Trial

Background

Depression is a common and serious problem among adolescents, but few seek or have access to therapy. Internet-delivered cognitive behavioral therapies (ICBTs), developed to increase treatment access, show promise in reducing depression. The inclusion of coach support in treatment is desired and may be needed.

Objective

The aim of this study was to determine the efficacy of an ICBT protocol blended with weekly real-time therapist sessions via chat; blended treatment, for adolescent depression, including major depressive episode (MDE). The protocol has previously been evaluated in a controlled study.

Methods

In a two-arm randomized controlled trial, adolescents 15 to 19 years of age were recruited through a community setting at the national level in Sweden (n=70) and allocated to either 8 weeks of treatment or to minimal attention control. Depression was assessed at baseline, at posttreatment, and at 12 months following treatment (in the intervention group). The primary outcome was self-reported depression level as measured with the Beck Depression Inventory II at posttreatment. The intervention was offered without the need for parental consent.

Results

Over two weeks, 162 adolescents registered and completed the baseline screening. Eligible participants (n=70) were on average 17.5 years of age (SD 1.15), female (96%, 67/70), suffered from MDE (76%, 53/70), had no previous treatment experience (64%, 45/70), and reported guardian(s) to be aware about their depression state (71%, 50/70). The average intervention completion was 74% (11.8 of 16 modules and sessions). Following the treatment, ICBT participants demonstrated a significant decrease in depression symptoms compared with controls (P<.001), corresponding to a large between-group effect (intention-to-treat analysis: d=0.86, 95% CI 0.37-1.35; of completer analysis: d=0.99, 95% CI 0.48-1.51). A significant between-group effect was observed in the secondary depression outcome (P=.003); clinically significant improvement was found in 46% (16/35) of ICBT participants compared with 11% (4/35) in the control group (P=.001).

Conclusions

The results are in line with our previous study, further demonstrating that adolescents with depression can successfully be engaged in and experience significant improvement following ICBT blended with therapist chat sessions. Findings on participants’ age and baseline depression severity are of interest in relation to used study methods.

A systematic review of internet-delivered cognitive behavior therapy for alcohol misuse: study characteristics, program content and outcomes

Alcohol misuse is a common, disabling and costly issue worldwide. Internet-delivered cognitive behavior therapy (ICBT) has the potential to reduce the harms of alcohol misuse, particularly for individuals who are unable or unwilling to access face-to-face therapy. A systematic review was conducted using Medline, CINAHL, EMBASE and PsycINFO databases for all relevant articles published from 1980 to January 2019. Randomized controlled trials (RCTs) were included if (i) an ICBT intervention targeting alcohol misuse was delivered; (ii) participants were aged 18 years or older; and (iii) primary outcomes were quantity of drinking. A qualitative analysis was conducted on the content of the ICBT programs. Fourteen studies met inclusion criteria. Most studies included participants from the general population, while studies conducted within clinic settings with diagnosed individuals were rare. The programs were similar in terms of included modules. Small effects were seen in studies on self-guided ICBT, while therapist-guided ICBT rendered small to large effects. The current review indicates that ICBT has a significant effect in reducing alcohol consumption. Larger studies evaluating ICBT compared to active control groups especially within clinic settings are warranted.

Diminishing Effects After Recurrent Use of Self-Guided Internet-Based Interventions in Depression: Randomized Controlled Trial

Background

Self-guided internet-based interventions have several advantages over guided interventions and are generally effective in treating psychiatric symptoms.

Objective

We aimed to investigate whether the use of a new self-guided internet-based intervention (MOOD) would lead to a significant reduction in depressive symptoms compared with a care-as-usual (CAU) control group in a sample of individuals with depressive symptoms, most of whom had already used a different self-guided internet-based intervention in a previous trial.

Methods

A total of 125 individuals were randomized to the intervention condition (MOOD) and received access to the intervention for a period of six weeks or a CAU group. After six weeks, all participants were invited to take part in the post assessment. The Beck Depression Inventory-II served as the primary outcome.

Results

Both intention-to-treat as well as per-protocol analyses indicated that the depressive symptomatology decreased in both conditions but showed no advantage for those who had used MOOD. Subsequent moderation analyses suggested that those individuals who had less experience with psychotherapy benefitted to a greater extent compared with those with more experience.

Conclusions

Self-guided internet-based interventions are deemed a suitable first-step approach to the treatment of depression. However, our results indicate that they are more efficacious in those with less psychotherapy experience.

Experiences of computer-based and conventional self-help interventions for eating disorders: A systematic review and meta-synthesis of qualitative research

OBJECTIVE

Self-help interventions have been demonstrated to be effective in treating bulimic-type eating disorders (EDs). In particular, computer-based interventions have received increasing attention due to their potential to reach a wider population. This systematic review aimed to synthesize findings from qualitative studies on users' experiences of self-help interventions for EDs and to develop an exploratory framework.

METHOD

A systematic review and meta-synthesis on seven peer-reviewed qualitative studies on structured computer and book-based self-help interventions for EDs was conducted using Noblit and Hare's (1988) 7-phase meta-ethnography. Four of the selected studies investigated computer-based self-help programs, and three of the studies investigated book-based guided self-help programs.

RESULTS

Six concepts were synthesized. They included intervention-related factors (anonymity and privacy; accessibility and flexibility; guidance) and user-related factors (agency/autonomy; self-motivation; and expectations/attitudes). The study revealed the "machine-like" and relational properties of the computer; the expansion of treatment time and space in psychological interventions, the changing role of the medical health professional from a "therapist" to a "guide," and a change from understanding interventions as a conclusive treatment plan to a starting point or stepping stone toward recovery.

DISCUSSION

Computer-based self-help interventions should take advantage of the "machine-like" properties of a computer (neutrality, availability, etc.) as well as its ability to facilitate human interactions. Users should also be facilitated to have a realistic understanding of the purpose of self-help interventions and the place of self-help interventions in their broader treatment plans to moderate expectations and attitudes.

The efficacy of app-supported smartphone interventions for mental health problems: a meta-analysis of randomized controlled trials

Although impressive progress has been made toward developing empirically-supported psychological treatments, the reality remains that a significant proportion of people with mental health problems do not receive these treatments. Finding ways to reduce this treatment gap is crucial. Since app-supported smartphone interventions are touted as a possible solution, access to up-to-date guidance around the evidence base and clinical utility of these interventions is needed. We conducted a meta-analysis of 66 randomized controlled trials of app-supported smartphone interventions for mental health problems. Smartphone interventions significantly outperformed control conditions in improving depressive (g=0.28, n=54) and generalized anxiety (g=0.30, n=39) symptoms, stress levels (g=0.35, n=27), quality of life (g=0.35, n=43), general psychiatric distress (g=0.40, n=12), social anxiety symptoms (g=0.58, n=6), and positive affect (g=0.44, n=6), with most effects being robust even after adjusting for various possible biasing factors (type of control condition, risk of bias rating). Smartphone interventions conferred no significant benefit over control conditions on panic symptoms (g=-0.05, n=3), post-traumatic stress symptoms (g=0.18, n=4), and negative affect (g=-0.08, n=5). Studies that delivered a cognitive behavior therapy (CBT)-based app and offered professional guidance and reminders to engage produced larger effects on multiple outcomes. Smartphone interventions did not differ significantly from active interventions (face-to-face, computerized treatment), although the number of studies was low (n≤13). The efficacy of app-supported smartphone interventions for common mental health problems was thus confirmed. Although mental health apps are not intended to replace professional clinical services, the present findings highlight the potential of apps to serve as a cost-effective, easily accessible, and low intensity intervention for those who cannot receive standard psychological treatment.

A randomized controlled trial examining the efficacy of an internet-based cognitive behavioral therapy program for adolescents with anxiety disorders

BACKGROUND

Anxiety disorders are highly prevalent in adolescence, but access to health care services is limited and only few receive professional help. Internet-based cognitive behavioral therapy (ICBT) has been proposed to increase accessibility and reduce costs of treatment.

OBJECTIVE

The study evaluated the efficacy of a Danish version of the guided ICBT program ChilledOut Online, developed at the Centre for Emotional Health, Macquarie University, Australia.

METHOD

At the Centre for Psychological Treatment of Children and Adolescents, Aarhus University, Denmark, a randomized controlled trial was conducted with 70 adolescents (13-17 years) with anxiety disorders according to DSM-IV. Participants were randomly assigned to a 14-weeks therapist-guided ICBT or to a waitlist condition. Outcomes were evaluated post-treatment and at 3- and 12-month follow-up.

RESULTS

At post-treatment, the ICBT group significantly outperformed the waitlist condition with moderate to large between-group effect sizes on diagnostic severity and anxiety symptoms rated by clinicians, and by adolescents and their parents. Forty percent of adolescents in ICBT were free of their primary diagnosis compared to 16% in the waitlist condition. Treatment gains were maintained at 3- and 12-month follow-up.

CONCLUSION

Results of the study provide support for the efficacy of guided ICBT for adolescents with anxiety disorders.

A Digital Intervention Addressing Alcohol Use Problems (the "Daybreak" Program): Quasi-Experimental Randomized Controlled Trial

BACKGROUND

Alcohol use is prevalent in many societies and has major adverse impacts on health, but the availability of effective interventions limits treatment options for those who want assistance in changing their patterns of alcohol use.

OBJECTIVE

This study evaluated the new Daybreak program, which is accessible via mobile app and desktop and was developed by Hello Sunday Morning to support high-risk drinking individuals looking to change their relationship with alcohol. In particular, we compared the effect of adding online coaching via real-time chat messages (intervention group) to an otherwise self-guided program (control group).

METHODS

We designed the intervention as a randomized control trial, but as some people (n=48; 11.9%) in the control group were able to use the online coaching, the main analysis comprised all participants. We collected online surveys at one-month and three-months follow-up. The primary outcome was change in alcohol risk (measured with the alcohol use disorders identification test-consumption [AUDIT-C] score), but other outcomes included the number of standard drinks per week, alcohol-related days out of role, psychological distress (Kessler-10), and quality of life (EUROHIS-QOL). Markers of engagement with the program included posts to the site and comments on the posts of others. The primary analysis used Weighted Generalized Estimating Equations.

RESULTS

We recruited 398 people to the intervention group (50.2%) and 395 people to the control group (49.8%). Most were female (71%) and the mean age was 40.1 years. Most participants were classified as probably dependent (550, 69%) on the AUDIT-10, with 243 (31%) classified with hazardous or harmful consumption. We followed up with 334 (42.1%) participants at one month and 293 (36.9%) at three months. By three months there were significant improvements in AUDIT-C scores (down from mean 9.1 [SD 1.9] to 5.8 [SD 3.1]), alcohol consumed per week (down from mean 37.1 [SD 28.3] to mean 17.5 [SD 18.9]), days out of role (down from mean 1.6 [SD 3.6] to 0.5 [SD 1.6]), quality of life (up from 3.2 [SD 0.7] to 3.6 [SD 0.7]) and reduced distress (down from 24.8 [SD 7.0] to 19.0 [SD 6.6]). Accessing online coaching was not associated with improved outcomes, but engagement with the program (eg, posts and comments on the posts of others) were significantly associated with improvements (eg, in AUDIT-C, alcohol use and EUROHIS-QOL). Reduced alcohol use was found for both probably dependent (estimated marginal mean of 40.8 to 20.1 drinks) and hazardous or harmful alcohol users (estimated marginal mean of 22.9 to 11.9 drinks).

CONCLUSIONS

Clinically significant reductions in alcohol use were found, as well as reduced alcohol risk (AUDIT-C) and days out of role. Importantly, improved alcohol-related outcomes were found for both hazardous or harmful and probably dependent drinkers. Since October 2016, Daybreak has reached more than 50,000 participants. Therefore, there is the potential for the program to have an impact on alcohol-related problems at a population health level, importantly including an effect on probably dependent drinkers.

Computer-assisted psychological assessment and psychotherapy for collegians

OBJECTIVE

This article reviews research on computerized and computer-assisted psychological assessment and psychotherapy for college and university students.

METHOD

Published reviews of outcome research on the topic are reviewed, along with individual clinical trials and other relevant studies not covered by reviews, as well as reviews of closely-related research.

RESULTS

Computer-assisted assessment and psychotherapy have proven effective with collegians across samples, nations, and presenting concerns.

CONCLUSIONS

Currently-available digital technologies can address these mental health service delivery challenges: cost, limited human resources, failure of students to seek help, stigmatization of collegians seeking help, premature termination, inadequate process and outcome data to assess and improve treatment effectiveness, and lack of real-time data-based treatment selection.

Developing a digital intervention for cancer survivors: an evidence-, theory- and person-based approach

This paper illustrates a rigorous approach to developing digital interventions using an evidence-, theory- and person-based approach. Intervention planning included a rapid scoping review that identified cancer survivors' needs, including barriers and facilitators to intervention success. Review evidence (N = 49 papers) informed the intervention's Guiding Principles, theory-based behavioural analysis and logic model. The intervention was optimised based on feedback on a prototype intervention through interviews (N = 96) with cancer survivors and focus groups with NHS staff and cancer charity workers (N = 31). Interviews with cancer survivors highlighted barriers to engagement, such as concerns about physical activity worsening fatigue. Focus groups highlighted concerns about support appointment length and how to support distressed participants. Feedback informed intervention modifications, to maximise acceptability, feasibility and likelihood of behaviour change. Our systematic method for understanding user views enabled us to anticipate and address important barriers to engagement. This methodology may be useful to others developing digital interventions.

Effectiveness of an internet-based intervention for procrastination in college students (StudiCare Procrastination): Study protocol of a randomized controlled trial

BACKGROUND

Procrastination, defined as irrational and voluntary delaying of necessary tasks, is widespread and clinically relevant. Its high prevalence among college students comes with serious consequences for mental health and well-being of those affected. Research for proper treatment is still relatively scarce and treatment of choice seems to be cognitive behavior therapy (CBT). The aim of this study is to evaluate the effectiveness and acceptability of an internet- and mobile-based intervention (IMI) for procrastination based on CBT for college students.

METHODS

A two-armed randomized controlled trial with a calculated sample size of N = 120 participants with problematic procrastination behavior will be conducted. Students will be recruited in Germany, Austria and Switzerland via circular emails at 15+ cooperating universities in the framework of StudiCare, a well-established project that provides IMIs to college students for different health related issues. The intervention group will receive the e-coach guided 5-week IMI StudiCare Procrastination. A waitlist-control group will get access to the unguided IMI 12 weeks after randomization. Assessments will take place before as well as 6 and 12 weeks after randomization. Primary outcome is procrastination, measured by the Irrational Procrastination Scale (IPS). Secondary outcomes include susceptibility to temptation, depression, anxiety, wellbeing and self-efficacy as well as acceptability aspects such as intervention satisfaction, adherence and potential side effects. Additionally, several potential moderators as well as the potential mediators self-efficacy and susceptibility to temptation will be examined exploratorily. Data-analysis will be performed on intention-to-treat basis.

DISCUSSION

This study will contribute to the evidence concerning effectiveness and acceptability of an intervention for procrastination delivered via the internet. If it shows to be effective, StudiCare Procrastination could provide a low-threshold, cost-efficient way to help the multitude of students suffering from problems caused by procrastination.Trial registration: The trial is registered at the WHO International Clinical Trials Registry Platform via the German Clinical Studies Trial Register (DRKS): DRKS00014321 (date of registration: 06.04.2018). In case of important protocol modifications, trial registration will be updated.Trial status: This is protocol version number 1, 11th December 2019. Recruitment started 9th of April 2018 and was completed 30th of November 2018. Assessment and intervention are still ongoing and will be completed by April 2019.

The Effects of Positive Psychological Interventions on Medical Patients' Anxiety: A Meta-analysis

OBJECTIVE

Positive psychology interventions, which involve systematic completion of activities designed to promote well-being, are being increasingly studied in medically ill patients. However, the extent to which these interventions ameliorate patient anxiety remains unclear. Therefore, the aim of the study was to conduct a meta-analysis to determine the efficacy of positive psychology interventions in reducing anxiety in medical patients.

METHODS

Electronic databases Medline, PsycINFO, SciELO, Cochrane (Central), and ClinicalTrials.gov were searched from inception to June 18, 2018, to identify studies of positive psychology interventions that included a validated measure of anxiety as an outcome measure.

RESULTS

The search generated a total of 1024 studies. Twelve randomized controlled trials (n = 1131) delivered to medical patients were included in the review, and a further 11 nonrandomized trials (n = 300) were included in a secondary analysis. Positive psychology interventions were effective at reducing patient anxiety relative to a control with a small to medium effect size (g = -0.34, 95% confidence interval = -0.50 to -0.18), and results were maintained at a mean of 8-week follow-up (g = -0.31, 95% confidence interval = -0.54 to -0.08). Clinician-led interventions seemed to be more effective than self-administered interventions, and longer interventions were more effective than shorter interventions. Secondary analysis of nonrandomized trials also found that positive psychology interventions are associated with reduced anxiety.

CONCLUSIONS

Positive psychology interventions seem to be effective at reducing medical patient anxiety. Future research is needed to determine optimal intervention characteristics, including dose and intervention content, that maximize the observed treatment effects.

The therapist experience of internet delivered CBT for problem gambling: Service integration considerations

INTRODUCTION

Countries with legalized gambling offer a network of government funded face-to-face therapy, but usage of this expertise is on the decline. One way to address this issue is to recruit therapists from existing services whereby they provide guidance for the delivery of internet delivered CBT.

OBJECTIVE

To explore the experiences and perceptions of therapists supporting guided online cognitive-behavioural therapy.

METHODS

Interviewees were a sub-sample of therapists from a randomised trial that investigated the relative efficacy of online guided self-directed versus pure self-directed interventions in Australia.

RESULTS

In-person, semi-structured interviews with seven service providers were completed, and thematic content analysis identified five themes which related to: participant suitability and screening (e.g., motivation, computer literacy and access); program content and modality acceptability (e.g., amount of content, look and feel); participant information and management (e.g., program engagement and progression); email communication (e.g., use of templates, appointments, rapport building), and; ongoing service integration (e.g., infrastructure, confidence in product). Overall experiences and perceptions of therapists were positive, notwithstanding barriers concerning assessment of participant suitability, participant management systems and low participant engagement.

CONCLUSIONS

Key themes emphasized the benefits of Internet-based interventions for problem gambling, and suggested several areas for improvement. Results should inform the development of future treatments to enable flexible tailoring of interventions to individuals.

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.

Predicting engagement with an online psychosocial intervention for psychosis: Exploring individual- and intervention-level predictors

BACKGROUND

Individuals with psychosis demonstrate positive attitudes towards utilising digital technology in mental health treatment. Although preliminary research suggests digital interventions are feasible and acceptable in this population, little is known about how to best promote engagement with these resources. Candidate predictors include therapist support, sources of motivation and recovery style. Understanding what factors predict engagement will aid more effective design and implementation of digital interventions to improve clinical benefits.

OBJECTIVE

This study aimed to investigate demographic, psychological, and treatment variables that predict overall and type of engagement with a psychosocial, online intervention for individuals with psychosis.

METHODS

Ninety-eight participants with a history of psychosis were given access to a web program containing modules on self-management and recovery, which they were asked to use flexibly at their own pace. Activity was automatically logged by the system. Baseline measures of demographics, recovery style and motivation were administered, and participants were randomised to receive either website access alone, or website access plus weekly, asynchronous emails from an online coach over 12 weeks. Log and baseline assessment data were used in negative binomial regressions to examine predictors of depth and breadth of use over the intervention period. A logistic regression was used to examine the impact of predictor variables on usage profiles (active or passive).

RESULTS

Depth and breadth of engagement were positively predicted by receiving email support, low levels of externally controlled motivations for website use, older age, and having a tertiary education. There was a significant interaction between level of controlled motivation and condition (+/-email) on breadth and depth of engagement: receiving asynchronous emails was associated with increased engagement for individuals with low, but not high, levels of externally controlled motivations. Receiving email support and more autonomous motivations for treatment predicted more active use of the website.

CONCLUSIONS

Asynchronous email support can promote engagement with online interventions for individuals with psychosis, potentially enabling self-management of illness and improving clinical outcomes. However, those using online interventions due to external motivating factors, may have low levels of engagement with the intervention, irrespective of coaching provided. These findings may guide design and implementation of future online interventions in this population.
