What makes self-help interventions effective in the management of depressive symptoms? Meta-analysis and meta-regression

Types and mechanisms of idiographic change during guided self-help for anxiety

OBJECTIVES

To compare idiographic change during two formats of guided self-help (GSH); cognitive-behavioural therapy guided self-help (CBT-GSH) and cognitive analytic therapy guided self-help (CAT-GSH).

DESIGN

Qualitative inductive thematic analysis.

METHODS

Semi-structured interviews with N = 17 participants with a reliable change outcome on the GAD-7 after completing GSH for anxiety. Changes were categorised and themes extracted.

RESULTS

No differences between CAT-GSH and CBT-GSH were found regarding types of change reported. The five overarching themes found were personal qualities of success, enlightenment through understanding, specific tools and techniques, changes to relationships and tailoring support. Four themes maximally differentiated between the two different types of GSH; CAT-GSH enabled relational insight and change whilst CBT-GSH enabled better understanding of anxiety, new coping techniques and supportive relationships.

CONCLUSIONS

Both common and model-specific factors contribute to patient change during GSH. Whilst all forms of GSH are grounded in the psychoeducational approach, separate theoretical foundations and associated methods facilitate different types of ideographic change.

The impact of school-based creative bibliotherapy interventions on child and adolescent mental health: a systematic review and realist synthesis protocol

BACKGROUND

There is a need to identify evidence-based interventions to be delivered in schools that can be used to improve child and adolescent mental health and wellbeing. Creative bibliotherapy is one proposed intervention. However, there has been, to date, no comprehensive assessment of the evidence for its impact on mental health and wellbeing. To fill this gap, we will conduct a systematic review and realist synthesis.

METHODS

A systematic search of the bibliographic databases APA PsycINFO, Medline (via Ovid), CINAHL, ERIC, Education Research Complete (via EBSCOhost) and Web of Science (SCI, SSCI, AHCI, ESCI) for school-based creative bibliotherapy interventions on child and adolescent mental health. Types of study to be included: cohort studies, non-randomised comparative evaluations, randomised controlled trials. The data from all included studies will be summarised descriptively and strength of evidence appraised. This is a potentially large field of practice, with heterogeneous interventions; we will use methods from intervention components analysis to describe and categorise the range of components and approaches used in included interventions. To understand how interventions work and in which contexts, we will use methods from realist synthesis to develop an exploratory account of mechanisms in different settings and for different young people (contexts).

DISCUSSION

Findings will assess the range of evidence for the impact of creative bibliotherapy on child and adolescent mental health and wellbeing, the strength of evidence for the impact identified, and describe potential mechanisms. This review will be useful for a wide range of stakeholders considering implementing or developing interventions using creative bibliotherapy in school-based settings.

Self-care interventions to assist family physicians with mental health care of older patients during the COVID-19 pandemic: Feasibility, acceptability, and outcomes of a pilot randomized controlled trial

BACKGROUND

The COVID-19 pandemic has required family physicians to rapidly address increasing mental health problems with limited resources. Vulnerable home-based seniors with chronic physical conditions and commonly undermanaged symptoms of anxiety and depression were recruited in this pilot study to compare two brief self-care intervention strategies for the management of symptoms of depression and/or anxiety.

METHODS

We conducted a pilot RCT to compare two tele-health strategies to address mental health symptoms either with 1) validated CBT self-care tools plus up to three telephone calls from a trained lay coach vs. 2) the CBT self-guided tools alone. The interventions were abbreviated from those previously trialed by our team, to enable their completion in 2 months. Objectives were to assess the feasibility of delivering the interventions during a pandemic (recruitment and retention); and assess the comparative acceptability of the interventions across the two groups (satisfaction and tool use); and estimate preliminary comparative effectiveness of the interventions on severity of depression and anxiety symptoms. Because we were interested in whether the interventions were acceptable to a wide range of older adults, no mental health screening for eligibility was performed.

RESULTS

90 eligible patients were randomized. 93% of study completers consulted the self-care tools and 84% of those in the coached arm received at least some coaching support. Satisfaction scores were high among participants in both groups. No difference in depression and anxiety outcomes between the coached and non-coached participants was observed, but coaching was found to have a significant effect on participants' use and perceived helpfulness of the tools.

CONCLUSION

Both interventions were feasible and acceptable to patients. Trained lay coaching increased patients' engagement with the tools. Self-care tools offer a low cost and acceptable remote activity that can be targeted to those with immediate needs. While effectiveness results were inconclusive, this may be due to the lack of eligibility screening for mental health symptoms, abbreviated toolkit, and fewer coaching sessions than those used in our previous effective interventions.

Behavioural and psychological telehealth support for people with cardiac conditions: randomized trial of the 'back on track' self-management programme

AIMS

Behaviour modification and mood management are essential to recovery after a cardiac event. Recent times have seen a major shift to remote delivery of cardiac services. This study assessed behavioural and psychological outcomes of the Back on Track online self-management programme, comparing the programme undertaken alone (self-directed) vs. with telephone support (supported). Relevance for people with depression was also assessed.

METHODS AND RESULTS

Participants with cardiac conditions (n = 122) were randomly assigned to self-directed or supported groups and given access to the online programme for 2 months. The programme addressed depression, anxiety, physical activity, and healthy eating. Supported group participants also received two telephone sessions facilitated by a trained counsellor to further enhance their self-management skills and engagement with the online modules. The Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Active Australia Survey and Diet Quality Tool were administered at baseline, 2, and 6 months. χ2 tests were used to compare self-directed and supported groups. Cochrane's Q tests assessed changes over time in depression, anxiety, and physical activity (PA) and healthy diet guideline achievement. Participants in both groups showed reduced depression rates (self-directed, P < 0.05) and increased PA after programme completion (both groups, P < 0.05). Amongst those classified as depressed at baseline, significantly fewer were classified as depressed over time (P < 0.001) and significantly more were achieving the PA guidelines (P < 0.01) compared to those who were not depressed at baseline.

CONCLUSIONS

The Back on Track telehealth programme was effective in assisting with behavioural and emotional recovery after a cardiac event. The programme may be particularly beneficial for those who are depressed early in their recovery period.

Effect of self-help interventions on psychological, glycemic, and behavioral outcomes in patients with diabetes: A meta-analysis of randomized controlled trials

BACKGROUND

Self-help interventions are beneficial for patients with diabetes; however, related studies have reported conflicting results. To date, no review has examined the effect of self-help interventions on diabetes outcomes.

OBJECTIVES

To systematically evaluate the effects of self-help interventions on psychological, glycemic, and behavioral outcomes in patients with diabetes.

DESIGN

A systematic review and meta-analysis of randomized controlled trials.

METHODS

Five databases-PubMed, CINAHL, Embase, PsycINFO, and ClinicalTrials.gov-were searched from 1996, 1937, 1947, 1887, and 2000, respectively, to 2 June 2023. Studies that employed a randomized controlled trial design, enrolled adults with diabetes, implemented a self-help intervention as the main or an additional intervention, and reported the outcomes of interest were included. Studies providing self-help interventions to patients with gestational diabetes or pregnant women were excluded. The primary outcomes were diabetes distress, depression, and anxiety, and the secondary outcomes were glycemic and behavioral outcomes (self-management behavior, self-efficacy, and quality of life). Hedges' g and the associated 95 % confidence interval (CI) were calculated using a random-effects model to obtain the pooled estimates of short-, mid-, and long-term effects of self-help interventions. Heterogeneity was explored using I2 and Q statistics, and moderator analysis was performed to identify the sources of heterogeneity.

RESULTS

Of 17 eligible studies, 16 provided data for meta-analysis. We included 3083 patients with diabetes; the majority were women (61.95 %), and their average age was 55.13 years. Self-help interventions exerted significant short-term effects on diabetes distress (g = -0.363; 95 % CI = -0.554, -0.173), depression (g = -0.465; 95 % CI = -0.773, -0.156), anxiety (g = -0.295; 95 % CI = -0.523, -0.068), glycosylated hemoglobin level (g = -0.497; 95 % CI = -0.791, -0.167), self-efficacy (g = 0.629; 95 % CI = 0.060, 1.197), and quality of life (g = 0.413; 95 % CI = 0.104, 0.721; g = 0.182; 95 % CI = 0.031, 0.333; and g = 0.469; 95 % CI = 0.156, 0.783 for overall, physical, and mental domains, respectively). We also noted significant mid-term effects of self-help interventions on diabetes distress (g = -0.195; 95 % CI = -0.374, -0.016), self-management behavior (g = 0.305; 95 % CI = 0.155, 0.454), and overall quality of life (g = 0.562; 95 % CI = 0.315, 0.810). The certainty of evidence ranged from high to very low certainty for the measured outcomes.

CONCLUSIONS

Self-help interventions may have some positive effects on diabetes distress, anxiety, self-management behavior, and quality of life.

TWEETABLE ABSTRACT

This meta-analysis demonstrated that self-help interventions might improve psychological and behavioral outcomes in patients with diabetes.

Using machine learning to forecast symptom changes among subclinical depression patients receiving stepped care or usual care

BACKGROUND

Subclinical depression (SD) is a mental health disorder characterized by minor depressive symptoms. Most SD patients are treated in the primary practice, but many respond poorly to treatment at the expense of provider resources. Stepped care approaches are appealing for tiering SD care to efficiently allocate scarce resources while jointly optimizing patient outcomes. However, stepped care can be time inefficient, as some persons may respond poorly and be forced to suffer with their symptoms for prolonged periods. Machine learning can offer insight into optimal treatment paths and inform clinical recommendations for incident patients.

METHODS

As part of the Step-Dep trial, participants with SD were randomized to receive stepped care (N=96) or usual care (N=140). Machine learning was used to predict changes in depressive symptoms every three months over a year for each treatment group.

RESULTS

Tree-based models were effective in predicting PHQ-9 changes among patients who received stepped care (r=0.35-0.46, MAE=0.14-0.17) and usual care (r=0.34-0.49, MAE=0.15-0.18). Patients who received stepped care were more likely to reduce PHQ-9 scores if they had high PHQ-9 but low HADS-A scores at baseline, a low number of chronic illnesses, and an internal locus of control.

LIMITATIONS

Models may suffer from potential overfitting due to sample size limitations.

CONCLUSION

Our findings demonstrate the promise of machine learning for predicting changes in depressive symptoms for SD patients receiving different treatments. Trained models can intake incident patient information and predict outcomes to inform personalized care.

Adaptation and outcomes of a lay-guided mental health self-care model: Results of six trials

OBJECTIVE

To synthesize results of six controlled trials of self-care interventions for depression and/or anxiety, focusing on five trials in which lay guidance was compared to self-directed use of the same self-care tools.

METHODS

The trials were conducted in Canada in different target populations. Self-care tools were adapted to each population. Guidance was provided in 3-15 calls over a period of 6-26 weeks. Depression and/or anxiety were assessed at follow-up (6-26 weeks). Pooled analyses used a meta-analytic approach. Engagement with the self-care tools was compared using the standardized difference or Cohen's d effect size.

RESULTS

In studies with homogeneous outcomes (three for depression, four for anxiety), the pooled effect sizes of guidance vs. self-directed use of the self-care tools were 0.36 (95% CI 0.10, 0.62, N = 235) for depression and 0.21 (95% CI -0.03, 0.44, N = 285) for anxiety. Guidance consistently led to greater engagement with the tools.

CONCLUSIONS

The intervention model is a potentially sustainable and accessible alternative to professionally guided self-care for people with mild-moderate depression. Factors which may have limited implementation success include: co-interventions, reduced number of guide calls (3 vs 6 or more), and delivery to dyads (patient-caregiver).

Effectiveness of a mental health stepped-care programme for healthcare workers with psychological distress in crisis settings: a multicentre randomised controlled trial

BACKGROUND

Evidence-based mental health interventions to support healthcare workers (HCWs) in crisis settings are scarce.

OBJECTIVE

To evaluate the capacity of a mental health intervention in reducing anxiety and depression symptoms in HCWs, relative to enhanced care as usual (eCAU), amidst the COVID-19 pandemic.

METHODS

We conducted an analyst-blind, parallel, multicentre, randomised controlled trial. We recruited HCWs with psychological distress from Madrid and Catalonia (Spain). The intervention arm received a stepped-care programme consisting of two WHO-developed interventions adapted for HCWs: Doing What Matters in Times of Stress (DWM) and Problem Management Plus (PM+). Each intervention lasted 5 weeks and was delivered remotely by non-specialist mental health providers. HCWs reporting psychological distress after DWM completion were invited to continue to PM+. The primary endpoint was self-reported anxiety/depression symptoms (Patient Health Questionnaire-Anxiety and Depression Scale) at week 21.

FINDINGS

Between 3 November 2021 and 31 March 2022, 115 participants were randomised to stepped care and 117 to eCAU (86% women, mean age 37.5). The intervention showed a greater decrease in anxiety/depression symptoms compared with eCAU at the primary endpoint (baseline-adjusted difference 4.4, 95% CI 2.1 to 6.7; standardised effect size 0.8, 95% CI 0.4 to 1.2). No serious adverse events occurred.

CONCLUSIONS

Brief stepped-care psychological interventions reduce anxiety and depression during a period of stress among HCWs.

CLINICAL IMPLICATIONS

Our results can inform policies and actions to protect the mental health of HCWs during major health crises and are potentially rapidly replicable in other settings where workers are affected by global emergencies.

Yes, I can! Development and validation of the self-efficacy for self-help scale

BACKGROUND

Self-help interventions for health complaints promise alleviation, for instance, of depressive symptoms, and have become increasingly popular. However, despite constant progress regarding digitally supported self-help, real-world uptake is low and motivational processes, like task-specific self-efficacy, are rarely investigated. Therefore, this study developed and tested the Self-Efficacy for Self-Help Scale (SESH).

METHODS

In a randomized controlled trial of a positive psychological online intervention to foster self-help, 344 adults (mean age = 49.26 years, SD = 27.85; 61.9 % female) completed SESH at three time points (pretest, posttest, 2-week follow-up). Psychometric testing included factorial validity, reliability (internal consistency, split-half), convergent validity (via depression coping self-efficacy), discriminant validity (via depression severity, depression literacy), sensitivity to change (due to the intervention), and predictive validity (via a theory of planned behavior questionnaire on self-help).

RESULTS

The unidimensional scale showed excellent reliability, construct validity, and predictive validity regarding self-help (the theory of planned behavior explained 49 % of variance in self-help intentions). The analysis did not clearly support sensitivity to change, however, as SESH scores did not change in the intervention group but were lower in the control group at posttest.

LIMITATIONS

The study was not representative of the population, and the intervention was not previously tested. Studies with longer follow-ups and more diverse samples are needed.

CONCLUSIONS

This study closes a gap in current self-help research by presenting a psychometrically sound measure to capture self-efficacy for self-help that can be used in epidemiological studies as well as clinical practice.

"Get Stuck and Can't Walk Out": Exploring the Needs for Support Among Chinese Immigrant Women Experiencing Intimate Partner Violence in the United States

Chinese immigrant survivors of intimate partner violence (IPV) in the United States have been overlooked and underserved. The purpose of this study was to explore their perceptions of resources for assistance as well as their priority needs. We conducted phone interviews with 20 Chinese immigrant women who had experienced IPV in the past year. The women expressed their needs for emotional support, culturally specific services, a variety of online resources to meet different demands, being empowered, raising the Chinese community's awareness about IPV, and batterer intervention programs. These women's testimonies shows that greater effort should be directed toward addressing those needs in order to reduce IPV and its impacts on health in this vulnerable group of women.

Adherence to e-health interventions for substance use and the factors influencing it: Systematic Review, meta-analysis, and meta-regression

Background

Substance use disorders affect 36 million people globally, but only a small proportion of them receive the necessary treatment. E-health interventions have been developed to address this issue by improving access to substance use treatment. However, concerns about participant engagement and adherence to these interventions remain. This review aimed to evaluate adherence to e-health interventions targeting substance use and identify hypothesized predictors of adherence.

Methods

A systematic review of literature published between 2009 and 2020 was conducted, and data on adherence measures and hypothesized predictors were extracted. Meta-analysis and meta-regression were used to analyze the data. The two adherence measures were (a) the mean proportion of modules completed across the intervention groups and (b) the proportion of participants that completed all modules. Four meta-regression models assessed each covariate including guidance, blended treatment, intervention duration and recruitment strategy.

Results

The overall pooled adherence rate was 0.60 (95%-CI: 0.52-0.67) for the mean proportion of modules completed across 30 intervention arms and 0.47 (95%-CI: 0.35-0.59) for the proportion of participants that completed all modules across 9 intervention arms. Guidance, blended treatment, and recruitment were significant predictors of adherence, while treatment duration was not.

Conclusion

The study suggests that more research is needed to identify predictors of adherence, in order to determine specific aspects that contribute to better exposure to intervention content. Reporting adherence and predictors in future studies can lead to improved meta-analyses and the development of more engaging interventions. Identifying predictors can aid in designing effective interventions for substance use disorders, with important implications for e-health interventions targeting substance use.

Online interventions for cannabis use among adolescents and young adults: Systematic review and meta-analysis

BACKGROUND

Young people present high rates of cannabis use, abuse, and dependence. The United Nations estimates that roughly 3.8% of the global population aged 15-64 years used cannabis at least once in 2017. Cannabis use in young people may impair cognitive skills, interfere with learning, impact relationships, and lead to long term behavioural and psychological consequences. Online cannabis interventions (OCI) are increasingly popular, but their dissemination is not often supported by empirical evidence.

AIM

To systematically compile and analyse the effectiveness of OCI for the reduction of cannabis use among adolescents and young adults (AYA).

METHODS

Pooled effect sizes of cannabis use between treatment and control groups were estimated. For each comparison, Hedge's g was calculated using a random effects model.

RESULTS

The search strategy yielded 4531 articles. Of those, a total of 411 articles were retrieved for detailed evaluation resulting in 17 eligible studies (n = 3525). Analyses revealed that online interventions did not significantly reduce cannabis consumption (Hedge's g = -0.061, 95% CI [-0.363] to [-0.242], p = .695) and high heterogeneity was noted (Q = 191.290). More recent studies using structured interventions, daily feedback, AYA centred designs, and peer support, specifically targeting CU seemed to have positive effects to address CU in this population.

CONCLUSIONS

The lack of positive outcomes suggests that more specific and targeted interventions may be necessary to promote cannabis-related behavioural change among young people. These targeted interventions may include structured CU modules, daily feedback, peer support for increased adherence, user-centred design procedures, and input from key stakeholders such as families and service providers.

Trained lay coaches and self-care cognitive-behavioral tools improve depression outcomes

OBJECTIVES

Identify the key effective components of a depression self-care intervention.

METHODS

Secondary analysis of data from 3 studies that demonstrated effectiveness of a similar depression self-care intervention (n = 275): 2 studies among patients with chronic physical conditions and 1 among cancer survivors. The studies used similar tools, and telephone-based lay coaching. Depression remission and reduction at 6 months were assessed with either PHQ-9 (chronic condition cohorts) or CES-D (cancer survivor cohort). Multiple logistic regression was used to analyze data when the interaction p-value with cohort was < 0.10.

RESULTS

The 3 coached cohorts achieved better depression outcomes than usual care. The combination of coaching and joint use of 2 tools based on cognitive-behavioral therapy (CBT) was associated with depression remission and reduction among chronic condition cohorts but not among cancer survivors. Neither the number nor the length of coach calls were associated with outcomes in pooled data.

CONCLUSIONS

Trained lay coaching and use of CBT-based self-care tools were associated with improved depression outcomes in patients with chronic conditions but not among cancer survivors.

PRACTICE IMPLICATIONS

Trained lay coaching and CBT tools are key components of depression self-care interventions. Further research is needed on the effective components in cancer survivors.

Cognitive, behavioural or cognitive-behavioural self-help interventions for subclinical depression in older adults: A systematic review and meta-analysis

BACKGROUND

Subclinical depression is a risk factor for the development of major depression in older adults. We aimed to determine the effectiveness of pure self-help or self-help with minimal support to reduce depressive symptoms and to prevent the onset of major depression in this population.

METHODS

This was a systematic review and meta-analysis of trials that used self-administrated cognitive, behavioural or cognitive-behavioural interventions for older adults with subclinical depression compared to control groups. Medline, Embase, PsycInfo and Cochrane databases were searched for relevant studies.

RESULTS

We analysed eight trials involving 1449 participants. A small but significant effect favouring the intervention was found at short-term [d = 0.33; 95% CI (Confidence Interval): 0.20-0.47] and at long-term (d = 0.22; 95% CI: 0.04-0.40) for depressive symptoms. None of the studies looked at the preventive effect of self-help interventions in reducing the probability of a subsequent diagnosis of major depression.

LIMITATIONS

The low number of studies meant that it was not possible to test for publication bias. The absence of pre-published protocols for many of the studies meant that there is a possibility of selective reporting bias for some of the primary studies.

CONCLUSIONS

There is some evidence that cognitive-behavioural self-help interventions may reduce depressive symptoms in older adults with subclinical depression. However, no study examined whether the intervention had a preventative effect in reducing the likelihood of a subsequent diagnosis of major depression.

Guided self-help Urdu version of the living life to the full intervention for secondary school adolescents with low mood and anxiety in Pakistan: A feasibility study

There is limited evidence on the efficacy of Cognitive Behavioral Therapy (CBT) based guided self-help programs to improve low mood and anxiety in Pakistani adolescents. The aims of the current study were to assess the effectiveness of an eight week low intensity CBT-based guided self-help program, Living Life to the Full (LLTTF) on depression, anxiety and social functioning among secondary school adolescents in Pakistan. Fifty-six participants were randomly allocated to immediate (n = 28) and delayed access (n = 28) groups. Measures of depression, anxiety and social functioning were collected at baseline, post intervention and three months follow-up. There were significant improvements in measures of depression (t = -3.47, p < 0.01; d = 1.0), anxiety (t = -6.55, p < 0.001; d = 1.91) and social functioning (t = -4.28, p < 0.001) between immediate access and delayed access groups. These differences remained significant at three months follow-up. The study suggests that the Urdu LLTTF book course delivered in classes is effective for reducing depression and anxiety as well as improving social function among adolescents in Pakistan.

The benefits of psychosocial interventions for mental health in men who have sex with men living with HIV: a systematic review and meta-analysis

OBJECTIVE

Men who have sex with men (MSM) living with HIV are more likely to suffer from mental health problems. They should be given adequate attention to treat and improve their mental health disorders. This meta-analysis aimed to assess whether psychosocial interventions reliably improve psychological well-being among MSM living with HIV.

METHOD

Cochrane Library, EMBASE, PsycINFO, and PubMed were searched for psychosocial intervention randomized controlled trials evaluating mental health (e.g., depression, anxiety, self-efficacy). The effect size was pooled using the random-effects model, and continuous outcomes were reported using standardized mean difference (SMD) values .

RESULTS

A total of 12 studies including 1782 participants were included in the meta-analysis. Psychosocial interventions in contrast to control groups significantly reduced depression (SMD, - 0.28; 95% CI - 0.52 - - 0.03) at the follow-up assessment and improved quality of life (SMD 0.43, 95% CI 0.23-0.63) after treatment. Psychosocial interventions also had a significant effect on measures of self-efficacy (SMD 2.22, 95% CI 0.24-4.20), and this effect was sustained until long-term follow-up (SMD 0.55, 95% CI 0.02-1.08). Subgroup analyses revealed that improvements in depression were more significant when participants possessed higher education and treatment providers used cognitive behavioral therapy (CBT).

CONCLUSIONS

The findings of this study indicate that psychosocial interventions benefit the mental health of MSM living with HIV. It is necessary to conduct more research to explore characteristics that may affect treatment outcomes in the future.

Remotely Delivered Interventions to Support Women With Symptoms of Anxiety in Pregnancy: Mixed Methods Systematic Review and Meta-analysis

BACKGROUND

Symptoms of anxiety are common in pregnancy, with severe symptoms associated with negative outcomes for women and babies. Low-level psychological therapy is recommended for women with mild to moderate anxiety, with the aim of preventing an escalation of symptoms and providing coping strategies. Remotely delivered interventions have been suggested to improve access to treatment and support and provide a cost-effective, flexible, and timely solution.

OBJECTIVE

This study identifies and evaluates remotely delivered, digital, or web-based interventions to support women with symptoms of anxiety during pregnancy.

METHODS

This mixed methods systematic review followed a convergent segregated approach to synthesize qualitative and quantitative data. The ACM Digital Library, Allied and Complementary Medicine Database, Applied Social Sciences Index and Abstracts, Centre for Reviews and Dissemination database, the Cochrane Central Register of Controlled Trials, the Cochrane Library, CINAHL, Embase, Health Technology Assessment Library, IEEE Xplore, Joanna Briggs Institute, Maternity and Infant Care, MEDLINE, PsycINFO, and the Social Science Citation Index were searched in October 2020. Quantitative or qualitative primary research that included pregnant women and evaluated remotely delivered interventions reporting measures of anxiety, fear, stress, distress, women's views, and opinions were included.

RESULTS

Overall, 3 qualitative studies and 14 quantitative studies were included. Populations included a general antenatal population and pregnant women having anxiety and depression, fear of childbirth, insomnia, and preterm labor. Interventions included cognitive behavioral therapy, problem solving, mindfulness, and educational designs. Most interventions were delivered via web-based platforms, and 62% (8/13) included direct contact from trained therapists or coaches. A meta-analysis of the quantitative data found internet-based cognitive behavioral therapy and facilitated interventions showed a beneficial effect in relation to the reduction of anxiety scores (standardized mean difference -0.49, 95% CI -0.75 to -0.22; standardized mean difference -0.48, 95% CI -0.75 to -0.22). Due to limitations in the amount of available data and study quality, the findings should be interpreted with caution. Synthesized findings found some evidence to suggest that interventions are more effective when women maintain regular participation which may be enhanced by providing regular contact with therapists or peer support, appropriate targeting of interventions involving components of relaxation and cognitive-based skills, and providing sufficient sessions to develop new skills without being too time consuming.

CONCLUSIONS

There is limited evidence to suggest that women who are pregnant may benefit from remotely delivered interventions. Components of interventions that may improve the effectiveness and acceptability of remotely delivered interventions included providing web-based contact with a therapist, health care professional, or peer community. Women may be more motivated to complete interventions that are perceived as relevant or tailored to their needs. Remote interventions may also provide women with greater anonymity to help them feel more confident in disclosing their symptoms.

Can We Prevent Depression in At-Risk Older Adults Using Self-Help? The UK SHARD Trial of Behavioral Activation

BACKGROUND

Treatment of established depression is the dominant approach to care of older adults, but prevention holds much promise. Self-help interventions are a feasible preventive approach, since they are scalable and low cost. There are few trials in this area. Behavioral Activation (BA) is a credible candidate psychological approach, which has been shown to work in therapist led care but not been trialled in a self-help form.

AIM

To test the effectiveness of an unguided self-help intervention based on BA for older adults.

METHODS

We compared a self-help intervention based on BA for older people (n = 172) to usual care (n = 160) in a pragmatic randomized controlled trial. Outcomes were depression status and severity (PHQ9) and health related quality of life (SF12). The primary timepoint of the primary outcome was depression at 4 months, with longer term follow up at 12 months to test sustained impact of the primary outcome.

RESULTS

At 4 months adjusted PHQ-9 scores for BA self-help were 0.79 lower (95% CI: -1.70 to 0.13; p = 0.09) and the proportion of participants with case-level depression was significantly reduced (BA 31/137 (22.6%) versus usual care 41/141 (29.1%); Odds Ratio 0.48; 95% CI: 0.26-0.92; p = 0.03). There was no PHQ-9 difference at 12 months or for health related quality of life at any point (4 or 12 months).

DISCUSSION

Self-help using BA for older people at risk of depression is a feasible and scalable intervention with potential short-term benefits in preventing depression.

Clinical Effectiveness of Blended CBT Compared vs Face-to-Face CBT for adult depression: a Randomised Controlled Non-Inferiority Trial (Preprint)

Background

Internet-based cognitive behavioral therapy (iCBT) has been demonstrated to be cost- and clinically effective. There is a need, however, for increased therapist contact for some patient groups. Combining iCBT with traditional face-to-face (FtF) consultations in a blended format may produce a new treatment format (B-CBT) with multiple benefits from both traditional CBT and iCBT, such as individual adaptation, lower costs than traditional therapy, wide geographical and temporal availability, and possibly lower threshold to implementation.

Objective

The primary aim of this study is to compare directly the clinical effectiveness of B-CBT with FtF-CBT for adult major depressive disorder.

Methods

A 2-arm randomized controlled noninferiority trial compared B-CBT for adult depression with treatment as usual (TAU). The trial was researcher blinded (unblinded for participants and clinicians). B-CBT comprised 6 sessions of FtF-CBT alternated with 6-8 web-based CBT self-help modules. TAU comprised 12 sessions of FtF-CBT. All participants were aged 18 or older and met the diagnostic criteria for major depressive disorder and were recruited via a national iCBT clinic. The primary outcome was change in depression severity on the 9-item Patient Health Questionnaire (PHQ-9). Secondary analyses included client satisfaction (8-item Client Satisfaction Questionnaire [CSQ-8]), patient expectancy (Credibility and Expectancy Questionnaire [CEQ]), and working (Working Alliance Inventory [WAI] and Technical Alliance Inventory [TAI]). The primary outcome was analyzed by a mixed effects model including all available data from baseline, weekly measures, 3-, 6, and 12-month follow-up.

Results

A total of 76 individuals were randomized, with 38 allocated to each treatment group. Age ranged from 18 to 71 years (SD 13.96) with 56 (74%) females. Attrition rate was 20% (n=15), which was less in the FtF-CBT group (n=6, 16%) than in the B-CBT group (n=9, 24%). As many as 53 (70%) completed 9 or more sessions almost equally distributed between the groups (nFtF-CBT=27, 71%; nB-CBT=26, 68%). PHQ-9 reduced 11.38 points in the FtF-CBT group and 8.10 in the B-CBT group. At 6 months, the mean difference was a mere 0.17 points. The primary analyses confirmed large and significant within-group reductions in both groups (FtF-CBT: β=–.03; standard error [SE] 0.00; P<.001 and B-CBT: β=–.02; SE 0.00; P<.001). A small but significant interaction effect was observed between groups (β=.01; SE 0.00; P=.03). Employment status influenced the outcome differently between groups, where the B-CBT group was seen to profit more from not being full-time employed than the FtF group.

Conclusions

With large within-group effects in both treatment arms, the study demonstrated feasibility of B-CBT in Denmark. At 6 months’ follow-up, there appeared to be no difference between the 2 treatment formats, with a small but nonsignificant difference at 12 months. The study seems to demonstrate that B-CBT is capable of producing treatment effects that are close to FtF-CBT and that completion rates and satisfaction rates were comparable between groups. However, the study was limited by small sample size and should be interpreted with caution.

Descriptive review of internet-based cognitive behavior therapy on anxiety-related problems in children under the circumstances of COVID-19

Background

COVID-19 continues to have a global impact and has yet to converge. Behavioral restrictions in daily life are widespread, forcing changes to the behavioral patterns of people. Significant changes have also occurred in children’s lives, raising concerns about mental health. The same is true for anxiety symptoms.

Research

In this paper, we described the COVID-19 pandemic effects on mental health, summarized Internet-based cognitive behavioral therapy (ICBT) as an applicability of cognitive behavioral therapy (CBT) for COVID-19, and summarized ICBT’s current state as a response for anxiety. An overview of previous intervention studies, including randomized controlled trials (RCTs) on ICBT, showed that many studies were highly effective against anxiety symptoms. Furthermore, regarding the follow-up of ICBT’s intervention effect, long-term effect maintenance was also clarified. It was likewise pointed out that ICBT may be used in the future since it is beneficial for children’s anxiety symptoms in telemedicine.

Conclusions

Based on these results from previous studies, we discuss ICBT’s applicability during the COVID-19 pandemic. Additionally, future measures and prospects for children’s mental health during the pandemic are discussed in this study.

Getting "Back on Track" After a Cardiac Event: Protocol for a Randomized Controlled Trial of a Web-Based Self-management Program

Background

After a cardiac event, a large majority of patients with cardiac conditions do not achieve recommended behavior change targets for secondary prevention. Mental health issues can also impact the ability to engage in health behavior change. There is a need for innovative, flexible, and theory-driven eHealth programs, which include evidence-based strategies to assist patients with cardiac conditions with their recovery, especially in behavioral and emotional self-management.

Objective

The aim of this study is to determine the short- and longer-term behavioral and emotional well-being outcomes of the Back on Track web-based self-management program. In addition, this study will test whether there is enhanced benefit of providing one-on-one telephone support from a trained lifestyle counselor, over and above benefit obtained through completing the web-based program alone.

Methods

People who have experienced a cardiac event in the previous 12 months and have access to the internet will be eligible for this study (N=120). Participants will be randomly assigned to one of the two study conditions: either “self-directed” completion of the Back on Track program (without assistance) or “supported” completion of the Back on Track program (additional 2 telephone sessions with a lifestyle counselor). All participants will have access to the web-based Back on Track program for 2 months. Telephone sessions with the supported arm participants will occur at approximately 2 and 6 weeks post enrollment. Measures will be assessed at baseline, and then 2 and 6 months later. Outcome measures assessed at all 3 timepoints include dietary intake, physical activity and sitting time, smoking status, anxiety and depression, stage of change, and self-efficacy in relation to behavioral and emotional self-management, quality of life, and self-rated health and well-being. A demographic questionnaire will be included at baseline only and program acceptability at 2 months only.

Results

Recruitment began in May 2020 and concluded in August 2021. Data collection for the 6-month follow-up will be completed by February 2022, and data analysis and publication of results will be completed by June 2022. A total of 122 participants were enrolled in this study.

Conclusions

The Back on Track trial will enable us to quantify the behavioral and emotional improvements obtained and maintained for patients with cardiac conditions and, in particular, to compare two modes of delivery: (1) fully self-directed delivery and (2) supported by a lifestyle counselor. We anticipate that the web-based Back on Track program will assist patients in their recovery and self-management after an acute event, and represents an effective, flexible, and easily accessible adjunct to center-based rehabilitation programs.

"We Are All Trying to Find a Way to Help Ourselves": A Look at Self-Help Strategies Among Psychotherapy Clients

Objective: This study examined self-help strategies engaged by psychotherapy clients and explored their views on such self-help approach.

Methods: Secondary analysis of data from a qualitative research study was conducted. A total of 15 psychotherapy clients were recruited, and data were collected via semi-structured interviews. Thematic analysis of data was conducted using inductive approach to examine the content.

Results: Three main themes revolving around self-help strategies were identified: (1) types of self-help strategies, (2) reasons for engaging in self-help activities, and (3) effectiveness of self-help strategies.

Conclusion: The self-help approach to manage distress is common among psychotherapy clients. This study provided insights into understanding how and why clients use self-help strategies in their daily lives.

Guided Self-help Teletherapy for Behavioural Difficulties in Children with Epilepsy

Behavioural difficulties impact greatly upon quality of life for children with chronic illness and their families but are often not identified or adequately treated, possibly due to the separation of physical and mental health services. This case study describes the content and outcomes of guided self-help teletherapy for behavioural difficulties in a child with epilepsy and complex needs using an evidence-based behavioural parenting protocol delivered within a paediatric hospital setting. Behavioural difficulties and progress towards the family's self-identified goals were monitored at each session. Validated measures of mental health and quality of life in children were completed before and after intervention and satisfaction was measured at the end of treatment. Measures demonstrated clear progress towards the family's goals and reduction in weekly ratings of behavioural difficulties. This case demonstrates that a guided self-help teletherapy approach delivered from within the paediatric setting may be one way of meeting unmet need.

Efficacy of web-based self-management interventions for depressive symptoms: a meta-analysis of randomized controlled trials

BACKGROUND

The incidence of depression is increasing worldwide. Depression can lead to poor physical health and even suicide. However, in high-income countries, only about 50% of the people with depression receive appropriate therapy, and the detection rate of depression in low- and middle-income countries is relatively lower. Web-based self-management enables remote treatment and solves the problem of insufficient psychological treatment resources. Many past studies have evaluated the effectiveness of web-based self-management of depression, but there has been no synthesis of evidence. Therefore, this study conducted a meta-analysis of the effectiveness of web-based self-management for depressive symptoms.

METHOD

Six electronic databases (Cochrane Central Register of Controlled Trials, PubMed, Web of Science, Embase, CINAHL, and PsycINFO) were searched in September 2020. All literature referring to the effects of web-based self-management on depression were shortlisted by performing the medical subject headings (MeSH) search combined with a text word search.

RESULTS

A total of 18 eligible randomized controlled trials were identified, and the results from 3055 participants were consolidated. The web-based self-management group exhibited a greater reduction in depressive symptoms than the control group (g = - 0.46; 95% CI: 0.62,0.30), and there was no evidence of publication bias. Subgroup analysis revealed that patients with moderate-to-severe depression benefited from web-based self-management interventions. In terms of interventions, those based on cognitive behavioral therapy (CBT) were highly effective. We noted that the longer the intervention time, the better was the improvement in the status of depression. Furthermore, it was established that participants who communicated with therapists and showed greater adherence to the intervention experienced significant improvement in their symptoms. The results of the intervention group were better than those of the waiting-list, treatment-as-usual, and online psychoeducation groups.

CONCLUSIONS

Web-based self-management is a promising therapy for depression. Future research should aim to refine these aspects of the intervention to achieve a beneficial impact.

Study quality and efficacy of psychological interventions for posttraumatic stress disorder: a meta-analysis of randomized controlled trials

BACKGROUND

Research indicates that higher study quality may be associated with smaller treatment effects. Yet, knowledge about the association between study quality and treatment efficacy for posttraumatic stress disorder (PTSD) is limited. We aimed at evaluating the efficacy of psychological interventions for adult PTSD and the association between study quality and treatment effects.

METHODS

We conducted a systematic search to identify randomized controlled trials (RCTs) that examined the efficacy of psychological interventions for chronic PTSD symptoms in adult samples with at least 70% of patients being diagnosed with PTSD by means of a structured interview. We assessed study quality using the following eight criteria from prior research: N ⩾ 50, all patients met criteria for PTSD, a treatment manual was used, therapists were trained, treatment integrity was checked, intent-to-treat analyses were applied, randomization was conducted by an independent party, and treatment outcome was conducted by blind assessors.

RESULTS

The search resulted in 136 RCTs with 8978 patients. Active treatment conditions were largely effective in reducing PTSD symptoms at posttreatment and follow-up (Hedges' g = 1.09 and 0.81, respectively) when compared to passive control conditions. The comparison to active control conditions at posttreatment and follow-up resulted in medium effect sizes. A total of 14 trials met all study quality criteria and these trials produced large effect sizes when compared to passive control conditions at posttreatment and follow-up.

CONCLUSIONS

Overall, study quality was not significantly associated with effect size. The findings indicate that psychological interventions can effectively reduce PTSD symptoms irrespective of study quality.

Use of a Self-guided Computerized Cognitive Behavioral Tool During COVID-19: Evaluation Study

BACKGROUND

Internet-based programs can help provide accessible and inexpensive behavioral health care to those in need; however, the evaluation of these interventions has been mostly limited to controlled trials. Data regarding patterns of use and effectiveness of self-referred, open-access online interventions are lacking. We evaluated an online-based treatment designed to address stress, depression, and conflict management, the Dartmouth PATH Program, in a freely available and self-guided format during the COVID-19 pandemic.

OBJECTIVE

The primary aim is to determine users' levels of stress and depression, and the nature of problems and triggers they reported during the COVID-19 pandemic. A secondary objective is to assess the acceptability and usability of the PATH content and determine whether such a program would be useful as a stand-alone open-access resource. The final objective is understanding the high dropout rates associated with online behavioral programs by contrasting the use pattern and program efficacy of individuals who completed session one and did not return to the program with those who came back to complete more sessions.

METHODS

Cumulative anonymous data from 562 individuals were analyzed. Stress triggers, stress responses, and reported problems were analyzed using qualitative analysis techniques. Scores on usability and acceptability questionnaires were evaluated using the sign test and Wilcoxon signed rank test. Mixed-effects linear modeling was used to evaluate changes in stress and depression over time.

RESULTS

A total of 2484 users registered from April through October 2020, most of whom created an account without initiating a module. A total of 562 individuals started the program and were considered in the data analysis. The most common stress triggers individuals reported involved either conflicts with family or spouses and work or workload. The most common problems addressed in the mood module were worry, anxiousness, or stress and difficulty concentrating or procrastination. The attrition rate was high with 13% (21/156) completing the conflict module, 17% (50/289) completing session one of the mood module, and 14% (16/117) completing session one of the stress module. Usability and acceptability scores for the mood and stress modules were significantly better than average. In those who returned to complete sessions, symptoms of stress showed a significant improvement over time (P=.03), and there was a significant decrease in depressive symptoms over all time points (P=.01). Depression severity decreased on average by 20% (SD 35.2%; P=.60) between sessions one and two.

CONCLUSIONS

Conflicts with others, worry, and difficulty concentrating were some of the most common problems people used the programs to address. Individuals who completed the modules indicated improvements in self-reported stress and depression symptoms. Users also found the modules to be effective and rated the program highly for usability and acceptability. Nevertheless, the attrition rate was very high, as has been found with other freely available online-based interventions.

Discovering Common Elements of Empirically Supported Self-Help Interventions for Depression in Primary Care: a Systematic Review

BACKGROUND

Although the efficacy of self-help cognitive-behavioral therapy (CBT) for depression has been well established, its feasibility in primary care settings is limited because of time and resource constraints. The goal of this study was to identify common elements of empirically supported (i.e., proven effective in controlled research) self-help CBTs and frameworks for effective use in practice.

METHODS

Randomized controlled trials (RCTs) for self-help CBTs for depression in primary care were systematically identified in Pubmed, PsycINFO, and CENTRAL. The distillation and matching model approach was used to abstract commonly used self-help techniques (practice elements). Study contexts associated with unique combinations of intervention elements were explored, including total human support dose (total face-to-face, telephone, and personalized email contact time recommended by the protocol), effective symptom domain (depression vs. general psychological distress), and severity of depression targeted by the study. Relative contribution to intervention success was estimated for individual elements and human support by conditional probability (CP, proportion of the number of times each element appeared in a successful intervention to the number of times it was used in the interventions identified by the review).

RESULTS

Twenty-one interventions (12 successful) in 20 RCTs and 21 practice elements were identified. Cognitive restructuring, behavioral activation, and homework assignment were elements appearing in > 80% of successful interventions. The dose of human support was positively associated with the proportion of interventions that were successful in a significant linear fashion (CPs: interventions with no support, 0.20; 1-119 min of support, 0.60; 120 min of support, 0.83; p = 0.042). In addition, human support increased the probability of success for most of the extracted elements. Only social support activation, homework assignment, and interpersonal skills were highly successful (CPs ≥ 0.60) when minimal support was provided.

DISCUSSION

These findings suggest that human support is an important component in creating an evidence-informed brief self-help program compatible with primary care settings.

Feasibility and preliminary effectiveness of an online training and support program for caregivers of people with dementia in India: a randomized controlled trial

OBJECTIVES

Internet-based interventions involving elements of cognitive behavior therapy, psychoeducation, relaxation and skills training for caregivers of people with dementia have been found to be promising in Western countries. Given these outcomes, the adapted version of a multi-component online caregiver skills training and support program of the World Health Organization, called iSupport, was tested for feasibility and preliminary effectiveness in India.

METHODS

One hundred fifty-one caregivers of family members with a diagnosis of Alzheimer's disease or dementia were randomized to either the intervention arm (iSupport; n = 74) or to the control group (an education-only e-book program; n = 77). Participants were assessed using self-rated measures of depression and perceived burden, which were the primary outcome measures, at baseline and 3-month follow-up. Person-centered attitude, self-efficacy, mastery and self-rated health were also assessed.

RESULTS

Fifty-five caregivers (29 in the iSupport group and 26 in the control condition) completed the study. The recruitment and retention rate of the study were 44.67% and 36.42% respectively. No significant differences were found between the two groups at 3-month follow-up on the primary outcomes. Among the secondary outcomes, significant improvement was only seen in caregivers' person-centered attitude towards persons with dementia in the iSupport group (t = 2.228; p < 0.05).

CONCLUSIONS

Despite efforts to recruit and retain participants to the online program, this study had a low recruitment and retention rate, which require closer attention and indicates a need for further adaptations of the Indian version of the iSupport program to improve its acceptability and accessibility. The lessons learned from this study will guide the further development of caregiver training and support interventions in India. The trial was registered with the Clinical Trials Registry-India (Trial Registration No. CTRI/2017/02/007876).

Low-Intensity Interventions and EMDR Therapy

Unlike high-intensity treatment, in which clients have face-to-face contact with a mental health specialist, clients in low-intensity treatment have limited or no contact with a specialist. Instead, their treatment is usually provided through self-help procedures, which are delivered via (guided) computer programs, books, or “mHealth" apps. Other treatments sometimes considered low-intensity are brief treatments, group therapy, and interventions delivered by nonspecialists. Advantages include effectiveness, accessibility, efficiency, and affordability. Concerns related to safety, engagement, and adherence to self-help programs may be addressed by (asynchronous) therapist guidance. This article describes low-intensity treatments and their relevance for eye movement desensitization and reprocessing (EMDR) therapy. Hundreds of randomized controlled trials (RCTs) have found self-help interventions to be efficacious, with many producing the same level of results as the traditional face-to-face procedure. Guided self-help cognitive behavioral therapy is recommended for the treatment of posttraumatic stress disorder in the guidelines of both the National Institute for Health and Care Excellence and International Society of Traumatic Stress Studies. Only three self-help-EMDR RCTs have been conducted. This author advocates for reconceptualizing EMDR group therapy as “guided self-help-EMDR therapy,” because it is a highly manualized, heavily scripted treatment in which the client works independently on their own material. In this respect, it offers an excellent template for the future development of efficacious low-intensity EMDR interventions. Developing safe, easy-to-use, affordable, and readily available low-intensity interventions will make effective EMDR treatment available to many millions of people around the world.

Telephone delivery of psychological interventions: Balancing protocol with patient-centred care

Common mental health problems of anxiety and depression affect significant proportions of the global population. Within the UK, and increasingly across western countries, a key policy response has been the introduction of high volume, low intensity psychological assessment and treatment services, such as the NHS's Improving Access to Psychological Therapies (IAPT) service, the largest service delivery model yet to be implemented at a national level (England). IAPT may be delivered in face-to-face meetings or over the telephone, as well as through other media. In order to increase access and achieve wide reach with efficient use of resources, IAPT's service models utilise relatively structured and standardised protocols, whilst aiming simultaneously to deliver a tailored and personalised experience for patients. Previous research has revealed that this can be a challenging balance for front-line practitioners to strike. Here we report research into the telephone delivery of guided self-help, low intensity interventions within IAPT, examining the challenges faced in remote delivery when combining structure with personalisation during assessment and treatment sessions. We show the ways in which the lack of flexibility in adhering to a system-driven structure can displace, defer or disrupt the emergence of the patient's story, thereby compromising the personalisation and responsiveness of the service. Our study contributes new insights to our understanding of the association between personalisation, engagement and patient experience within high volume, low-intensity psychological treatment services. Our research on the telephone delivery of IAPT is particularly timely in view of the current global Covid-19 health crisis, as a result of which face-to-face delivery of IAPT has had to be (temporarily) suspended.

CanDirect: Effectiveness of a Telephone-Supported Depression Self-Care Intervention for Cancer Survivors

PURPOSE

Depression in post-treatment cancer survivors is common and can impair quality of life. CanDirect is a novel, telephone-delivered depression self-care intervention for cancer survivors. We conducted a randomized controlled superiority trial to compare CanDirect with usual care (UC) in this population.

METHODS

Participants completing cancer treatment within the past 10 years who had mild-moderate depressive symptoms with or without major depression were recruited from clinical and community settings in Quebec and Ontario. Permuted block random assignment allocated participants to CanDirect plus UC or to UC alone. Assessments of depression severity (Center for Epidemiological Studies-Depression scale [CES-D]; primary outcome) and secondary outcomes health-related quality of life (Short Form Survey-12 mental and physical component summaries), anxiety symptoms (Hospital Anxiety and Depression Scale), activation (Patient Activation Measure), depression diagnosis (Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-IV), and health services (self-report) were conducted at baseline, as well as 3 and 6 months (primary time point). Analyses of outcomes were adjusted for covariates using linear regression and missing data by inverse probability weighting.

RESULTS

Participants recruited between September 2016 and October 2018 were randomly assigned to CanDirect (n = 121) or UC (n = 124). Among 245 participants randomly assigned, 218 (89.0%) completed the primary outcome at 6 months. CanDirect participants reported less severe depressive symptoms on the CES-D than UC participants at 6 months, adjusted effect size (ES) 0.61 (95% CI, 0.33 to 0.88). CanDirect participants also had significantly greater quality of life, lower anxiety, more activation, and lower rates of depression diagnoses, compared with UC. Exploratory analysis suggested that sex was a modifier of the primary outcome (interaction term P value = .03); the intervention was less effective in men (ES, 0.12; 95% CI, -0.45 to 0.69).

CONCLUSION

The findings suggest that CanDirect is an effective method of managing mild-moderate depression symptoms in cancer survivors.

Reducing Test Anxiety and Related Symptoms Using a Biofeedback Respiratory Practice Device: A Randomized Control Trial

Test Anxiety is a widespread psychological phenomenon. With prevalence rates of 20-40 percent of university students, it impedes adaptive functioning and life quality. Many available treatments for Test Anxiety involve the intervention of clinicians and usually a few months are required before symptom reduction is reported. The present randomized controlled trial examined a simple behavioral intervention-the use of breathing tools-as an exclusive therapy for Test Anxiety. Specifically, the efficacy of a biofeedback respiratory practice device was examined. 34 students were assigned to 3 treatment groups during their exam period: Biofeedback device group, self-directed breathing exercise group, and psychoeducation group. Self-report measures of Test Anxiety were collected pre- and post-intervention. Participants also reported additional exploratory measures such as depression and anxiety, quality of life, and their perceived adaptive functioning post-intervention. The results reveal that only participants from the biofeedback device group reported a significant reduction in Test Anxiety symptoms (p's < 0.05). Participants from the biofeedback device group also reported a decrease in depression and anxiety symptoms and an increase in psychological wellbeing (p's < 0.05), a subscale of the quality of life questionnaire. Findings support the notion that using biofeedback respiratory devices may reduce students' Test Anxiety symptoms. Indications for further research are discussed.

24-Month Outcomes of Primary Care Web-Based Depression Prevention Intervention in Adolescents: Randomized Clinical Trial

Background

Adolescent depression carries a high burden of disease worldwide, but access to care for this population is limited. Prevention is one solution to curtail the negative consequences of adolescent depression. Internet interventions to prevent adolescent depression can overcome barriers to access, but few studies examine long-term outcomes.

Objective

This study compares CATCH-IT (Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training), an internet-based intervention, to a general health education active control for depression onset at 12 and 24 months in adolescents presenting to primary care settings.

Methods

A 2-site randomized trial, blinded to the principal investigators and assessors, was conducted comparing Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training to health education to prevent depressive episodes in 369 adolescents (193 youths were randomly assigned to Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training and 176 to health education) with subthreshold depressive symptoms or prior depressive episodes. Participants were recruited from primary care settings in the United States. The primary outcome was the occurrence of a depressive episode, determined by the Depression Symptom Rating. The secondary outcome was functioning, measured by the Global Assessment Scale.

Results

In intention-to-treat analyses, the adjusted hazard ratio favoring Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training for first depressive episode was not statistically significant at 12 months (hazard ratio 0.77, 95% CI 0.42-1.40, P=.39) and 24 months (hazard ratio 0.87, 95% CI 0.52-1.47, P=.61). Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal Training provided preventive benefit for first depressive episode for those with mild hopelessness or at least moderate paternal monitoring at baseline. Global Assessment Scale scores improved comparably in both groups (intention-to-treat).

Conclusions

A technology-based intervention for adolescent depression prevention implemented in primary care did not have additional benefit at 12 or 24 months. Further research is necessary to determine whether internet interventions have long-term benefit.

Psychological interventions for depression among informal caregivers of older adult populations: protocol of a systematic review and meta-analysis of randomised controlled trials

INTRODUCTION

Increased life expectancy has led to an increased demand for family members to provide informal care for their older relatives in the home. Many studies suggest informal caregivers are at greater risk of experiencing symptoms of depression. However, there is a lack of research examining the effectiveness of psychological interventions targeting these symptoms alongside clinical and methodological moderators potentially associated with intervention effectiveness. This review aims to address this gap and will inform the development of a psychological intervention targeting depression among adult-child caregivers of older parents, given many studies show that among informal caregivers of older adults, adult children experience specific difficulties and needs for psychological support. Further, the lack of studies targeting adult children specifically necessitates conducting this review targeting caregivers of older adults in general.

METHODS AND ANALYSIS

Randomised controlled trials of psychological interventions targeting symptoms of depression among informal caregivers will be identified via a systematic search of electronic databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica DataBase, PsycINFO, Cochrane Library and Web of Science) and supplemented by handsearching of previous systematic reviews, reference and forward citation checking, and expert contact. If possible, a meta-analysis will be conducted to examine the: (1) effectiveness of psychological interventions for depression among informal caregivers of older adults, (2) effectiveness of psychological interventions for secondary outcomes such as anxiety, stress, caregiver burden, psychological distress, quality of life, well-being and self-efficacy and (3) moderating effects of clinical and methodological factors on effectiveness.

ETHICS AND DISSEMINATION

Ethical approval will not be necessary for this study given primary data will not be collected. Results will inform the development of a psychological intervention for adult-child caregivers of older parents and will be disseminated through publication in peer-reviewed journals and conference presentations.

Examining the effectiveness of an online program to cultivate mindfulness and self-compassion skills (Mind-OP): Randomized controlled trial on Amazon's Mechanical Turk

OBJECTIVES

The demand for effective psychological treatments for depression, anxiety, and heightened stress is far outstripping their supply. Accordingly, internet delivered, self-help interventions offer hope to many people, as they can be easily accessed and at a fraction of the price of face-to-face options. Mindfulness and self-compassion are particularly exciting approaches, as evidence suggests interventions that cultivate these skills are effective in reducing depression, anxiety, and heightened stress. We examined the effectiveness of a newly developed program that combines mindfulness, self-compassion, and goal-setting exercises into a brief self-guided intervention (Mind-OP). The secondary aim of this study was to investigate the feasibility of conducting a randomized-controlled trial entirely on a popular crowdsourcing platform, Amazon's Mechanical Turk (MTurk).

METHODS

We randomized 456 participants reporting heightened depression, anxiety, or stress to one of two conditions: the 4-week Mind-OP intervention (n = 227) or to an active control condition (n = 229) where participants watched nature videos superimposed onto relaxing meditation music for four consecutive weeks. We administered measures of anxiety, depression, perceived stress, dispositional and state mindfulness, self-compassion, and nonattachment.

RESULTS

Intent-to-treat and per-protocol analyses revealed that, compared to participants in the control condition, participants in the Mind-OP intervention condition reported significantly less anxiety and stress at the end of the trial, as well as significantly greater mindfulness, self-compassion, and nonattachment.

CONCLUSIONS

Mind-OP appears effective in reducing anxiety symptoms and perceived stress among MTurk participants. We highlight issues (e.g., attrition) related to feasibility of conducting randomized trials on crowdsourcing platforms such as MTurk.

The Therapeutic Alliance in Digital Mental Health Interventions for Serious Mental Illnesses: Narrative Review

BACKGROUND

Digital mental health interventions offer unique advantages, and research indicates that these interventions are effective for a range of mental health concerns. Although these interventions are less established for individuals with serious mental illnesses, they demonstrate significant promise. A central consideration in traditional face-to-face therapies is the therapeutic alliance, whereas the nature of a digital therapeutic alliance and its relationship with outcomes requires further attention, particularly for individuals with serious mental illnesses.

OBJECTIVE

This narrative review aims to encourage further consideration and critical evaluation of the therapeutic alliance in digital mental health, specifically for individuals with serious mental illnesses.

METHODS

A narrative review was conducted by combining 3 main areas of the literature: the first examining the evidence for digital mental health interventions for serious mental illnesses, the second illuminating the nature and role of the therapeutic alliance in digital interventions, and the third surrounding practical considerations to enhance a digital therapeutic alliance.

RESULTS

Results indicated that a therapeutic alliance can be cultivated in digital interventions for those with serious mental illnesses, but that it may have unique, yet-to-be-confirmed characteristics in digital contexts. In addition, a therapeutic alliance appears to be less directly associated with outcomes in digital interventions than with those in face-to-face therapies. One possibility is that the digital therapeutic alliance is associated with increased engagement and adherence to digital interventions, through which it appears to influence outcomes. A number of design and implementation considerations may enhance the digital therapeutic alliance, including human support and technological features.

CONCLUSIONS

More research is required to further understand the nature and specific role of a therapeutic alliance in digital interventions for serious mental illnesses, particularly in informing their design. This review revealed several key research priorities to advance the therapeutic alliance in digital interventions.

A comparison of electronically-delivered and face to face cognitive behavioural therapies in depressive disorders: A systematic review and meta-analysis

BACKGROUND

Cognitive behavioural therapy (CBT) is a widely used treatment for depression. However, limited resource availability poses several barriers to patients seeking access to care, including lengthy wait times and geographical limitations. This has prompted health care services to introduce electronically delivered CBT (eCBT) to facilitate access. Although previous reviews have compared the effects of eCBT to face-to-face CBT, there is an overall lack of adequately powered and up-to-date evidence in the literature to provide a reliable comparison between the two modes of administration. The purpose of this study is to evaluate the effects of eCBT compared to face-to-face CBT through a systematic review of the literature.

METHODS

To be eligible for this review, studies needed to be randomized controlled trials evaluating the clinical effectiveness of any form of eCBT compared to face-to-face CBT. These encompassed studies evaluating a wide range of outcomes including severity of symptoms, adverse outcomes, clinically relevant outcomes, global functionality, participant satisfaction, quality of life, and affordability. There were no restrictions on participant age or sex.We searched MEDLINE, EMBASE, Psych Info, Cochrane CENTRAL and CINAHL databases from inception to February 20th, 2020 using a comprehensive search strategy. All stages of literature screening and data extraction were completed independently in duplicate. Data extraction and risk of bias analyses, including GRADE ratings, were conducted on studies meeting inclusion criteria. Qualitative measures are reported in a narrative summary. We pooled quantitative data in meta-analyses to provide an estimated summary effect. This review adheres to PRISMA reporting guidelines.

FINDINGS

In total, we included 17 studies in our analyses. Our results demonstrated that eCBT was more effective than face-to-face CBT at reducing depression symptom severity (Standardized mean difference [SMD]: -1.73; 95% confidence interval [CI]: -2.72, -0.74; GRADE: moderate quality of evidence). There were no significant differences between the two interventions on participant satisfaction (SMD 0.13 95%; CI -0.32, 0.59; GRADE: low quality of evidence). One RCT reported eCBT to be less costly than face-to-face CBT (GRADE: low quality of evidence). Results did not differ when stratified by subgroups such as participant age and study location.

INTERPRETATION

Although we found eCBT to have moderate evidence of effectiveness in reducing symptoms of depression, high heterogeneity among studies precludes definitive conclusions for all outcomes. With the current reliance and accessibility of technology to increasing number of people worldwide, serious consideration in utilizing technology should be given to maximize accessibility for depression treatments. Our results found eCBT is at least as effective as face to face CBT, thus eCBT should be offered if preferred by patients and therapists.

Protecting the Mental Health of Small-to-Medium Enterprise Owners: A Randomized Control Trial Evaluating a Self-Administered Versus Telephone Supported Intervention

OBJECTIVE

Small-medium enterprises (SMEs) are under-represented in occupational health research. Owner/managers face mental ill-health risks/exacerbating factors including financial stress and long working hours. This study assessed the effectiveness of a workplace mental health and wellbeing intervention specifically for SME owner/managers.

METHODS

Two hundred ninety seven owner/managers of SMEs were recruited and invited to complete a baseline survey assessing their mental health and wellbeing and were then randomly allocated to one of three intervention groups: (1) self-administered, (2) self-administered plus telephone, or (3) an active control condition. After a four-month intervention period they were followed up with a second survey.

RESULTS

Intention to treat analyses showed a significant decrease in psychological distress for both the active control and the telephone facilitated intervention groups, with the telephone group demonstrating a greater ratio of change.

CONCLUSION

The provision of telephone support for self-administered interventions in this context appears warranted.

An examination of dysfunctional attitudes and extreme response styles as predictors of relapse in guided internet-based cognitive behavioral therapy for depression

OBJECTIVES

Internet-based cognitive behavioral therapy (iCBT) is an effective treatment option for depression, but its long-term effects are not well understood. We investigate for whom iCBT may have more enduring effects by evaluating dysfunctional attitudes as predictors of relapse.

METHODS

The sample consists of 31 iCBT responders (20 women, average age 31.6) who were followed for 1 year.

RESULTS

Higher Dysfunctional Attitudes Scale scores predicted higher risk of relapse (hazard ratio = 1.98). This relation remained significant when controlling for high style (dysfunctional) or content (functional) responses. Having relatively more positive extreme responses on style rather than content items did not predict risk of relapse.

CONCLUSIONS

Our results were consistent with the value of differentiating an extreme style of responding from otherwise endorsing belief in dysfunctional attitudes. Research that refines our understanding of patients' individual risk for relapse has the potential to inform how treatment might be individually tailored.

Effectiveness and acceptability of cognitive-behavioural therapy based interventions for maternal peripartum depression: a systematic review, meta-analysis and thematic synthesis protocol

INTRODUCTION

Peripartum depression is a common mental health difficulty associated with a range of negative impacts for the mother, infant and wider family. This review will examine the effectiveness of cognitive-behavioural therapy (CBT) based interventions for peripartum depression. Secondary aims are to explore the effect of CBT-based interventions targeted at peripartum depression on novel secondary outcomes and moderators potentially associated with effectiveness. To date, there has been little examination of effect on important secondary outcomes (eg, anxiety, stress and parenting), nor clinical and methodological moderators. Further, this review aims to explore the acceptability of CBT-based interventions for women with peripartum depression and examine important adaptations for this population.

METHODS AND ANALYSIS

Electronic databases (e.g., MEDLINE; ISI Web of Science; CINAHL; CENTRAL; Prospero; EMBASE; ASSIA; PsychINFO; SCOPUS; And Swemed+) will be systematically searched. Database searches will be supplemented by expert contact, reference and citation checking, and grey literature. Primary outcomes of interest will be validated measures of symptoms of depression. A proposed meta-analysis will examine: (1) the overall effectiveness of psychological interventions in improving symptoms of depression (both self-reported and diagnosed major depression) in the peripartum period; (2) the impact of interventions on secondary outcomes (eg, anxiety, stress and parenting); (3) clinical and methodological moderators associated with effectiveness. A thematic synthesis will be conducted on qualitative data exploring the acceptability of CBT-based intervention for postpartum depression including participants' experience and perspectives of the interventions, satisfaction, barriers and facilitators to intervention use, intervention relevance to mothers' situations and suggestions for improvements to tailor interventions to the peripartum client group.

ETHICS AND DISSEMINATION

Formal ethical approval is not required by the National Ethical Review Board in Sweden as primary data will not be collected. The results will be disseminated through a peer-reviewed publication and inform the development of a new psychological intervention for peripartum depression. This study including protocol development will run from March 2019 to March 2020.

The (cost) effectiveness of guided internet-based self-help CBT for dialysis patients with symptoms of depression: study protocol of a randomised controlled trial

BACKGROUND

Only a minority of dialysis patients with depressive symptoms are diagnosed and receive treatment. Depressive symptoms are highly prevalent in this population and are associated with adverse clinical outcomes. Underlying factors for this undertreatment may be the lack of evidence for the safety and effectivity of antidepressant medication, the reluctance of patients to adhere to antidepressant medication, the lack of mental healthcare provision in somatic healthcare environments and end-stage renal disease (ESRD) related physical limitations that complicate face-to-face psychotherapy. Guided Internet-based self-help treatment has demonstrated to be effective for depressive symptoms in other chronic patient populations and may overcome these barriers. The aim of this study is to investigate the (cost) effectiveness of a guided Internet-based self-help intervention for symptoms of depression in dialysis patients.

METHODS

This study is a cluster randomized controlled trial (RCT) that investigates the effectiveness of a 5-week Internet-based self-help Problem Solving Therapy (PST) for depressive symptoms in dialysis patients. Depressive symptoms will be measured using the Beck Depression Inventory - second edition (BDI-II), with a cut-off score of ≥10. We aim to include 206 dialysis patients with depressive symptoms who will be cluster randomized to the intervention or the Care as Usual (CAU) control group. Secondary outcomes will include anxiety symptoms, quality of life, economic costs and clinical outcomes, such as inflammatory factors and hair cortisol levels. Assessments will take place at baseline (T0), 2 weeks after intervention (T1) and 6 months (T2), 12 months (T3) and 18 months (T4) after intervention. The control group will be measured at the same time points. Analysis will be based on the intention-to-treat principle. Mixed models will be used to assess the changes within each condition between pre-treatment and post-treatment.

DISCUSSION

If demonstrated to be (cost) effective, Internet-based PST will offer new possibilities to treat dialysis patients with depressive symptoms and to improve their quality of care.

Modelling changes in anxiety and depression during low-intensity cognitive behavioural therapy: An application of growth mixture models

OBJECTIVES

Research largely supports the clinical effectiveness of low-intensity cognitive behavioural therapy (LICBT) for mild-to-moderate anxiety and depression, delivered by psychological well-being practitioners (PWPs). Knowledge regarding the predictors of treatment response, however, is relatively limited. The primary aim of this study was to model the heterogeneity in longitudinal changes in anxiety and depression throughout LICBT provided by PWPs in Northern Ireland (NI), and to explore associations between pre-treatment variables and differences in treatment response.

METHODS

Growth mixture modelling (GMM) techniques were employed to examine changes in psychological status in clients (N = 253) over the first six sessions of treatment, to identify divergent early response trajectories. A series of pre-treatment variables were used to predict class membership using chi-square tests and binary logistic regression models.

RESULTS

There was one class representing improvement and one representing no improvement for both anxiety and depression. Class membership was predictive of treatment outcome. Pre-treatment variables associated with less improvement included unemployment, risk of suicide, neglect of self or others, using medication, receiving previous or concurrent treatments, a longer duration of difficulties, and comorbidities.

CONCLUSIONS

Findings indicate most of the sample populated an 'improvers' class for both depression and anxiety. Pre-treatment variables identified as predictive of poor treatment response may need to be considered by practitioners in potential triage referral decision policies, supporting cost-effective and efficient services. Further research around predictors of clinical outcome is recommended.

PRACTITIONER POINTS

Most of the sample belonged to an 'improvers' class. Several pre-treatment variables predicted poor treatment response (unemployment, suicide risk, neglect, medication, previous or concurrent treatments, longer duration of difficulties, and comorbidities). Few studies have utilized GMM to determine predictors of outcome following LICBT Regarding pre-treatment variables, the possibility of self-report bias cannot be excluded. The time period was relatively short, although represented the optimum number of sessions recommended for LICBT. The lack of a control group and random allocation were the main limitations.

"Unrigging the support wheels" - A qualitative study on patients' experiences with and perspectives on low-intensity CBT

Background

Low-intensity treatments imply reduced therapist contact due to an emphasis on self-help and the use of technologies to deliver treatment. The role of the remoteness, the reduced therapist contact, and the interplay of these components has not been differentiated from a patients’ perspective so far. This study’s purpose is to capture patients’ experiences with telephone-based self-help cognitive behavioural therapy (tel-CBT).

Methods

A subsample of mildly to moderately depressed patients (N = 13) who finished tel-CBT as part of a larger randomised controlled trial (RCT) in routine care were interviewed using a semi-structured questionnaire. Interviews were audiotaped, transcribed verbatim, and independently coded by two coders blind to treatment outcome. Using qualitative content analysis with deductive and inductive procedures, a two-level category system was established.

Results

The category system contains four category clusters regarding expectations, self-help related aspects, telephone-related aspects, and implications for patients’ treatment pathway, and subsumes a total of 15 categories. Self-help related aspects circulate around the interplay between written materials and professional input, trust and support in the therapeutic relationship and its relation to the initial personal contact, as well as CBT principles. Telephone-related aspects entail perceived advantages and disadvantages of the telephone on an organisational and content level as well as a discourse around distance and closeness in the interaction. Although patients raised doubts regarding the long-term effect of the intervention on symptomatology, patients expressed satisfaction with the treatment and reported an immediate as well as a longer lasting personal impact of the treatment. These results indicate user acceptance with tel-CBT.

Conclusions

This qualitative analysis captures patients’ experiences with tel-CBT and the perceived helpfulness of the diverse treatment components. This can facilitate refining aspects of low-intensity treatments and might improve dissemination.

Supporting children with burns: Developing a UK parent-focused peer-informed website to support families of burn-injured children

BACKGROUND

Children's burn injuries can have a significant psychosocial impact on parents. However, the stress involved in caring for a child following a burn can often go unrecognized and does not necessarily prompt help seeking by parents.

OBJECTIVE

It is common for adults to seek health-related support and information via the Internet. Many benefit from immediate and easy access to online psychological interventions. A prototype burn-specific, parent-focused, peer-informed, supportive website, designed to provide easy access to information and psychoeducation, was created and tested for acceptability.

PATIENT INVOLVEMENT

Using a partnership-based method of website development, parents and professionals (clinical, academic and support organizations) were recruited and their particular expertise was acknowledged and valued. A participatory action approach was adopted to determine the acceptability of the website for parents/carers.

METHODS

31 participants (9 parents, 22 professionals) tested a prototype version of the website. Data was collected using the eHealth Impact Questionnaire and the concurrent think-aloud protocol.

RESULTS

Parents and professionals had favorable opinions of the website. Parents' ratings tended to be more favorable than professionals', which was significant for the information and presentation. Participants' thoughts were categorized into seven topics: need, structure/navigation, trust/relevance, language/comprehension, therapeutic content, mode of delivery, and suggested improvements.

DISCUSSION

Many practical and psychological barriers can prevent parents of burn-injured children accessing psychosocial support and contribute to a feeling of isolation. Participants felt that the website would be a valuable addition to UK pediatric burn care. The existence of an accessible resource could help to normalize parents' experience of their child's injury and reduce their perceived isolation, although peer interaction is not provided by the website.

PRACTICAL VALUE

This online resource, hosting information and peers' personal experiences, offers promising and exciting opportunities to empower parents whilst providing accessible supportive advice to encourage self-care and formal/informal support seeking when necessary.

Mental Health Promotion Intervention for Nurses Working in German Psychiatric Hospital Departments: A Pilot Study

This pilot study aimed to implement a mental health promotion program to support nurses working in Psychiatric hospital departments. Eighty-six nurses working in psychiatric hospitals were randomized to either an intervention group (IG) or a waitlist control group (WCG). The intervention took place in groups over a period of 12 weeks. Training content included, i.e. work-related stress management training, problem solving techniques, and solution-focused counseling. Outcomes were measured at four times (baseline and three follow-up measurements). Perceived stress, coping skills, emotion regulation skills and changes in patient relationships were included as outcome measurements. Psychiatric nurses in the IG reported significant changes in perceived job stress, emotion regulation skills, resilience, and self-efficacy after the intervention. In addition, scores on quality of patient-relationship were significantly higher after the intervention (e.g. support, conflict management; p < 0.05). No comparable results could be found in the WCG. A mental health promotion intervention for psychiatric nurses was successfully implemented. Further research is necessary to generalize these pilot study findings.
