Self-help Digital Interventions Targeted at Improving Psychological Well-being in Young People With Perceived or Clinically Diagnosed Reduced Well-being: Systematic Review

BACKGROUND

Levels of well-being are declining, whereas rates of mental health problems remain high in young people. The World Health Organization defines mental health as not merely the absence of mental disorder but also includes social and psychological well-being as integral to positive mental health, highlighting that mental health is applicable to young people with mental health conditions and those without a diagnosis of a mental health condition. Reduced mental well-being have been identified in studies of young people with clinical populations, as well as in populations consisting of nonclinical young people. Self-help digital interventions can be delivered at mass at a low cost and without the need for trained input, thereby facilitating access to support for well-being. Self-help interventions are effective in young people with mental health conditions, but systematic reviews of such studies have been limited to randomized controlled trials, have not included reduced well-being as an inclusion criterion, and do not consider engagement factors such as retention.

OBJECTIVE

The objective of this study was to systematically review all controlled studies of digitally delivered, self-administered interventions for young people aged 9 to 25 years, with perceived or clinically diagnosed reduced psychological well-being. Participant retention and effectiveness of the interventions were also explored.

METHODS

A systematic search of the PsycInfo, EMBASE, Cochrane, Scopus, and MEDLINE databases from inception to 2021, reference searches of relevant papers, and gray literature was carried out for digitally controlled studies conducted with young people with perceived or clinically diagnosed reduced well-being, aimed at improving psychological well-being. Data were extracted to identify the effectiveness and retention rates of the interventions and the quality of the studies.

RESULTS

Overall, 1.04% (12/1153) of studies met the inclusion criteria: 83% (10/12) of studies were randomized controlled trials and 17% (2/12) were controlled pre-post studies. Most (6/12, 50%) studies aimed to improve symptoms of depression; 3 interventions aimed at both anxiety and depressive symptoms and 2 studies aimed at improving social functioning difficulties. Owing to the high risk of bias across interventions and lack of similar outcome measures, a meta-analysis was not conducted. Retention rates across studies were regarded as good, with moderate to high retention. Overall, the findings indicated that predominantly self-administered self-help interventions improved well-being in the areas targeted by the intervention and identified additional areas of well-being that were positively affected by interventions. Few interventions supported psychological well-being that was different from those used by young people with a clinical diagnosis of mental illness or young people from neurodiverse backgrounds.

CONCLUSIONS

The findings, along with the advantages of self-help interventions, highlight the need for upscaling self-help interventions to better support vulnerable populations of young people who experience poor psychological well-being.

A Randomised Controlled Trial of Clinician-Guided Internet-Based Cognitive Behavioural Therapy for Depressed Patients in Singapore

This study examined the efficacy and acceptability of a hybrid, clinician-guided internet-based Cognitive Behavioural Therapy (iCBT) programme for outpatients with depression in a psychiatric hospital in Singapore. Fifty three participants were randomly assigned to a treatment or wait-list control group before they underwent a cross-over of conditions. Treatment consisted of a 4-week iCBT with three face-to-face sessions. 60.9% of participants who received treatment completed all six modules. Intention-to-treat analysis showed treatment was associated with significant reductions in symptoms of depression, anxiety and psychological distress but not in functional impairment, while the control condition was not associated with changes in any measures. These reductions had moderate to large effect sizes (ESs) for symptoms of depression and anxiety, and moderate ES for psychological distress. The between-group difference in depression score had a moderate ES. There was a significant between-group treatment effect in depressive symptoms, but not in the other measures. Treatment gains were maintained at 3-month follow-up. Most of the participants were highly satisfied with the programme, with 90 percent stating they would recommend it. This is the first RCT to provide preliminary evidence for the efficacy and acceptability of iCBT for depression in Singapore.

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.

Practitioner Review: Unguided and guided self-help interventions for common mental health disorders in children and adolescents: a systematic review and meta-analysis

Mental health problems are common in children and adolescents, yet evidence-based treatments are hard to access. Self-help interventions can increase such access. The aim of this paper was to conduct a systematic review and meta-analysis of the use of guided and unguided self-help for children and young people with symptoms of common mental health disorders. In contrast to previous reviews of self-help in children, all types of self-help and multiple mental health disorders were investigated in order to increase power to investigate potential moderators of efficacy. Importantly, studies with control arms as well as those comparing against traditional face-to-face treatments were included. Fifty studies (n = 3396 participants in self-help/guided self-help conditions) met the inclusion criteria. Results demonstrated a moderate positive effect size for guided and unguided self-help interventions when compared against a control group (n = 44; g = 0.49; 95% CI: 0.37 to 0.61, p < .01) and a small but significant negative effect size when compared to other therapies (n = 15; g = -0.17; 95% CI: -0.27 to -0.07, p < .01). Few potential moderators had a significant effect on outcome. Most comparisons resulted in significant heterogeneity and therefore results are interpreted with caution.

Self-Guided Web-Based Interventions: Scoping Review on User Needs and the Potential of Embodied Conversational Agents to Address Them

Background

Web-based mental health interventions have evolved from innovative prototypes to evidence-based and clinically applied solutions for mental diseases such as depression and anxiety. Open-access, self-guided types of these solutions hold the promise of reaching and treating a large population at a reasonable cost. However, a considerable factor that currently hinders the effectiveness of these self-guided Web-based interventions is the high level of nonadherence. The absence of a human caregiver apparently has a negative effect on user adherence. It is unknown to what extent this human support can be handed over to the technology of the intervention to mitigate this negative effect.

Objective

The first objective of this paper was to explore what is known in literature about what support a user needs to stay motivated and engaged in an electronic health (eHealth) intervention that requires repeated use. The second objective was to explore the current potential of embodied conversational agents (ECAs) to provide this support.

Methods

This study reviews and interprets the available literature on (1) support within eHealth interventions that require repeated use and (2) the potential of ECAs by means of a scoping review. The rationale for choosing a scoping review is that the subject is broad, diverse, and largely unexplored. Themes for (1) and (2) were proposed based on grounded theory and mapped on each other to find relationships.

Results

The results of the first part of this study suggest the presence of user needs that largely remain implicit and unaddressed. These support needs can be categorized as task-related support and emotion-related support. The results of the second part of this study suggest that ECAs are capable of engaging and motivating users of information technology applications in the domains of learning and behavioral change. Longitudinal studies must be conducted to determine under what circumstances ECAs can create and maintain a productive user relationship. Mapping the user needs on the ECAs’ capabilities suggests that different kinds of ECAs may provide different solutions for improving the adherence levels.

Conclusions

Autonomous ECAs that do not respond to a user’s expressed emotion in real time but take on empathic roles may be sufficient to motivate users to some extent. It is unclear whether those types of ECAs are competent enough and create sufficient believability among users to address the user’s deeper needs for support and empathy. Responsive ECAs may offer a better solution. However, at present, most of these ECAs have difficulties to assess a user’s emotional state in real time during an open dialogue. By conducting future research with relationship theory–based ECAs, the added value of ECAs toward user needs can be better understood.

Comparing human and automated support for depression: Fractional factorial randomized controlled trial

Web-based interventions for people with depressive symptoms are needed and show promising effects. However, it is a consistent finding that human support is needed and this makes implementation costly. This study investigates the adherence and effectiveness of a human-supported and automated-supported web-based intervention for people with mild to moderate depressive symptomatology, and studies the impact of four persuasive technology components. People with mild to moderate depressive symptoms according to the Center of Epidemiological Studies depression scale self-report questionnaire were included, but no diagnosis was made for the study. Participants (n = 239) were randomized into one of eight intervention arms, where each level of each component is present in half of the intervention arms. On clinical outcomes, there was a significant interaction effect between support condition and time, but there was no difference on the extent of improvement from baseline to follow-up, only a difference in the time-path of improvement. Effect sizes from baseline to follow-up were 0.89 for automated and 1.00 for human support. There was no significant difference on adherence between support condition. We conclude that an automated-supported web-based intervention for treatment of depression with persuasive technology may achieve similar adherence and effectiveness as the same intervention with human support.

Impact of Self-Help Schema Therapy on Psychological Distress and Early Maladaptive Schemas: A Randomised Controlled Trial

Self-help cognitive behaviour therapy has been found helpful in treating anxiety and depression. Recent evidence suggests that self-help schema therapy may represent another treatment alternative. The present study aimed to provide a preliminary assessment of the efficacy of self-help schema therapy on psychological distress and early maladaptive schemas (EMSs) using a 6-week treatment protocol with minimal email contact. Method: Participants were recruited from the general population and randomly assigned to self-help schema therapy (n = 32) or a waitlist (n = 32). Intent-to-treat analyses and study completer analyses were conducted using repeated-measures analyses of variance (time × group). Results: Intent-to-treat analyses revealed that treatment produced a marginal improvement in distress, but no change in EMSs. Among study completers (n = 34), self-help schema therapy yielded large reductions in distress scores on the Outcome Questionnaire-45.2 (partial eta squared = .16). Compared to the waitlist, self-help schema therapy also produced a moderate decrease in EMSs (partial eta squared = .10). The majority of study completers showed reliable clinical change in distress and reported high levels of satisfaction with the intervention. Conclusion: Self-help schema therapy may be an effective treatment for those individuals who persist in treatment. Self-help schema therapy has the potential to help a large number of individuals who may not otherwise have access to services. More research is needed to determine variables associated with treatment adherence and successful outcome.

CBT Guided Self-Help Compares Favourably to Gold Standard Therapist-Administered CBT and Shows Unique Benefits Over Traditional Treatment

CBT guided self-help (CBTgsh) can produce treatment outcomes comparable to therapist-administered CBT (CBTta) for the treatment of anxiety and depression. The efficacy of CBTgsh compared to gold standard CBTta, however, remains to be examined. The current article addresses this issue, as well as how CBTgsh may have unique benefits over CBTta. It further highlights ways in which CBTgsh may be used for disorders of increasing severity, using eating disorders and personality pathology for illustrative purposes. A literature review of PsycINFO, PsyARTICLES, and PubMED was conducted to identify relevant studies published since 1990. Studies directly comparing CBTgsh to gold standard CBTta for anxiety and depression, as well as bulimia nervosa, revealed no significant differences between the two interventions. Furthermore, CBTgsh may have unique benefits by encouraging continued improvement over time. Innovative eating disorder studies also show that CBTgsh can be used for more severe disorders as a supplementary treatment, and produces treatment outcomes superior to CBTta or treatment as usual alone. Based on these findings, CBTgsh applications to personality pathology are suggested. Traditional stepped care models, as they pertain to CBTgsh, may gain to be broadened both in their focus and methods of delivery.
