Psychotherapies for depression in low- and middle-income countries: a meta-analysis

Evidence Synthesis in Youth Mental Health for Low- and Middle-Income Countries-Authors' Reply

We thank Kumar et al.1 for their commentary on our meta-analysis of youth psychotherapies in LMICs.2 We appreciate the opportunity to elaborate on our findings and the points raised by Kumar et al. Kumar et al. raise the question of whether the data available are "mature" enough for a meta-analysis; we think that the answer to this question depends on the perceived purpose of a meta-analysis. If a meta-analysis were appropriate only for providing a definitive picture of the effects and moderators of an intervention, the currently available data would be insufficient; indeed, it is hard to imagine any pool of empirical studies on any question that would be mature enough to provide a definitive picture, because research is an iterative process, and new findings are continually changing the picture. In our view, every meta-analysis is simply a snapshot of the state of evidence at a particular point in time, intended to help researchers and practitioners to understand the state of the evidence, including its limitations, and to identify critical questions and gaps in knowledge that need attention in research. In the case of this meta-analysis, that means that the existing evidence base reflects issues with lack of optimal cultural adaptation and limited involvement of in-country individuals as authors. Such issues, which Kumar et al. appropriately highlight, shed light on the past and current state of our field, and can help us gain a clearer understanding of what needs to change.

Development of a digital program for training non-specialist providers to deliver a psychosocial intervention for depression: a formative study to support scaling up task-shared depression care in the United States

Task-sharing holds promise for bridging gaps in access to mental healthcare; yet there remain significant challenges to scaling up task-sharing models. This formative study aimed to develop a digital platform for training non-specialist providers without prior experience in mental healthcare to deliver a brief psychosocial intervention for depression in community settings in Texas. A 5-step development approach was employed, consisting of: blueprinting, scripting, video production and digital content creation, uploading digital content to a Learning Management System and user testing. This resulted in the development of two courses, one called Foundational Skills covering the skills to become an effective counselor, and the second called Behavioral Activation covering the skills for addressing adult depression. Twenty-one participants with a range of health-related backgrounds, including 11 with prior training in mental healthcare, completed the training and joined focus group discussions offering qualitative feedback and recommendations for improving the program's usability. Participant feedback centered around the need to make the content more interactive, to include additional engaging features, and to improve the layout and usability of the platform. The next steps will involve evaluating the training program on developing the skills of non-specialist providers and supporting its uptake and implementation.

The efficacy of cognitive behavioural therapy for depression and anxiety in multiple sclerosis: A systematic review and meta-analysis

BACKGROUND

Adults with multiple sclerosis (MS) frequently experience symptoms of depression and anxiety, which pose significant challenges. However, psychological support for these symptoms remains a major unmet healthcare need.

OBJECTIVES

To inform the evidence base for the psychological management of adults with MS, this study examined the efficacy of cognitive behavioural therapy (CBT) interventions for improving symptoms of depression and anxiety. CBT interventions teach skills for improving the relationships between an individual's thoughts, feelings, and/or behaviours. The study also examined the role of intervention and study characteristics as moderators of treatment effects.

METHODS

Medline, Embase, PsycINFO, and Cochrane Central Register of Controlled Trials were searched up to August 2024 for randomised control trials.

RESULTS

A meta-analysis of 15 clinical trials (1508 participants) was conducted, which found a medium significant treatment effect size for depression symptoms (g = 0.59, 95 % Confidence Interval [CI] [0.38, 0.80]) and a small significant treatment effect size for anxiety symptoms (g = 0.38 95 % CI [0.19, 0.57]). Moderator analyses revealed treatment effects for anxiety, but not depression, were significantly larger for studies conducted in non-Western countries compared to Western countries, and for those with smaller sample sizes.

CONCLUSIONS

CBT-based interventions appear efficacious for the management of depression and anxiety symptoms in adults with MS. However, future clinical trials with larger samples and more rigorous methodology are warranted. Further examination of intervention characteristics, including ways in which CBT is tailored and how this relates to outcomes, may help to refine interventions for people with MS.

Interpersonal Psychotherapy: A Review of Theory, History, and Evidence of Efficacy

Interpersonal psychotherapy (IPT) is an empirically validated treatment for mood disorders, anxiety disorders, eating disorders, and trauma. IPT is based on the concept of "relational frame"-that an individual's experience of psychological distress impacts those around them, and that their social support network impacts the distressed individual. This concept, along with the specific techniques and tools that flow from it and the theoretical bases of IPT (attachment and interpersonal theory) make IPT unique. In this article we review the theoretical bases of IPT (attachment and communication) and provide a brief history of IPT, as well as the evidence supporting its use for a variety of disorders. We also describe its application to groups, adolescents, and other diverse populations. Future directions for research and treatment development are proposed, particularly research in the area of combining IPT with other psychotherapeutic modalities.

Amount and frequency of psychotherapy as predictors of treatment outcome for adult depression: A meta-regression analysis

BACKGROUND

It is not clear whether the amount and frequency of psychotherapy is associated with treatment effects for adult depression. We investigated whether a number of indicators of the amount and frequency of psychotherapy were related to the treatment effects in randomized controlled trials (RCTs) comparing individual, face-to-face psychotherapy to a control group (e.g., care-as-usual [CAU] or waitlist condition [WL]).

METHODS

Four databases were systematically searched, and meta-regression analyses conducted to assess the relationship between the effect size (Hedges' g) of the treatment and number of sessions, duration of psychotherapy, total contact time with the therapist, and number of sessions per week.

RESULTS

We included 176 studies (210 comparisons) with 15,158 participants. We did not find a relationship between the effect size, and number of sessions, or total contact time. There was a small negative association between duration of treatment and the effect size, an additional week of treatment was related to a 0.014 decrease in the effect size. In addition, there was a strong association between number of sessions per week and the effect size, an increase from one to two sessions per week was related to an effect size higher by 0.596. Both associations were no longer significant when controlling for characteristics of studies.

LIMITATIONS

The current findings are correlational, future research should thus address this question in an RCT.

CONCLUSIONS

We should deliver brief therapies, and thus shorten waiting lists. More sessions, if necessary, should be delivered with higher frequency and over a shorter period of time.

Psychosocial interventions for depression among young people in Sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

Depression among young people is a global health problem due to its rising prevalence and negative physical and social outcomes. The prevalence of depression and the treatment gap among young people in Sub-Saharan Africa (SSA) is higher than global estimates. Most psychosocial interventions for adolescent and youth depression were developed in high-income countries and less is known about their effectiveness in SSA. Due to contextual differences, findings from High-Income Countries (HICs) are less applicable to SSA. Yet, no systematic review of psychosocial interventions for depression among young people in SSA has been conducted.

METHODS

A systematic literature search of four databases (Medline, Web of Science, PsycInfo, and Cochrane library) was conducted. Experimental studies published before May 2024 that evaluated the effect of psychosocial interventions on depressive symptoms among young people (aged 10-24 years) in SSA were included in the systematic review. Effect sizes (Hedge's g (g)) indicating differences between intervention and control groups were calculated using a random effects model.

RESULTS

Twenty-two eligible studies were identified for the systematic review, of which eighteen randomized control trials (RCTs) involving 2338 participants were included in the meta-analysis. The findings revealed that psychosocial interventions significantly reduced depressive symptoms (g = -1.55, 95% CI -2.48, -0.63), although heterogeneity was high (I2 = 98.8%). Subgroup analysis revealed that efficacy differed significantly by intervention type, with Cognitive Behavioural Therapy (9 studies) showing the strongest effect (g = -2.84, 95% CI -4.29; -1.38). While Wise Interventions (a form of positive psychology interventions; 2 studies) had a moderate effect (g = -0.46, 95% C.I -0.53, -0.39), Interpersonal Psychotherapy (2 studies; g = -0.08, 95% CI -1.05, 0.88) and Creative Psychological Interventions (3 studies; g = -0.29, 95% CI -1.38, 0.79) showed smaller, non-significant effects. Sensitivity analysis excluding studies at high risk of bias strengthened the effect size. Few studies assessed factors affecting intervention efficacy and showed mixed effects of age, gender, and adherence levels.

CONCLUSION

Psychosocial interventions, particularly CBT, significantly reduced depressive symptoms among young people in SSA. However, it is crucial to acknowledge the high heterogeneity which likely stems from variations in study populations and intervention delivery modalities. This highlights the need for further research to identify the specific intervention components and delivery methods that work best for distinct subpopulations. Future research should also explore how long intervention effects are maintained and factors affecting efficacy.

Exploring the Association between Serum B Vitamins, Homocysteine and Mental Disorders: Insights from Mendelian Randomization

Previous studies show that B vitamins and homocysteine (Hcy) may be associated with mental disorders, but the accurate causal relationship remains unclear. This study aimed to elucidate the potential causal relationship of serum B vitamins and Hcy levels with five common mental disorders through a two-sample Mendelian randomization (MR) study. In this MR analysis, 50 single-nucleotide polymorphisms (SNPs)-13 related to folate, 17 to vitamin B6, 8 to vitamin B12 and 12 to Hcy-were obtained from a large-scale Genome-Wide Association Studies (GWAS) database and employed as instrumental variables (IVs). The MR analyses were conducted using the inverse variance weighted (IVW), weighted median (WM), MR-Egger methods and sensitivity analyses were further performed to test the robustness. This MR study found a suggestive causal relationships between serum vitamin B12 levels and the risk of anxiety disorders (odds ratio (OR): 1.34, 95% confidence interval (CI): 1.01-1.78, p = 0.046) and bipolar affective disorders (OR: 1.85, 95% CI: 1.16-2.96, p = 0.010). However, folate, vitamin B6 and Hcy levels may not be causally associated with the risk of mental disorders. In conclusion, this study reveals that elevated serum vitamin B12 levels might suggestively increase the risk of anxiety and bipolar affective disorders, even though horizontal pleiotropy cannot be completely eliminated. The potential implications of our results warrant validation in larger GWAS based on diverse populations.

A Glossary of Distress Expressions Among Kannada-Speaking Urban Hindu Women

People's lived experiences of distress are complex, personal, and vary widely across cultures. So, too, do the terms and expressions people use to describe distress. This variation presents an engaging challenge for those doing intercultural work in transcultural psychiatry, global mental health, and psychological anthropology. This article details the findings of a study of common distress terminology among 63 Kannada-speaking Hindu women living in Mysuru, the second largest city in the state of Karnataka, South India. Very little existing scholarship focuses on cultural adaptation for speakers of Dravidian languages like Kannada; this study aims to fill this gap and support greater representation of this linguistic family in research on mental health, idioms of distress, and distress terminology. Between 2018 and 2019, we conducted a 3-phase study consisting of interviews, data reduction, and focus group discussions. The goal was to produce a non-exhaustive list of common Kannada distress terms that could be used in future research and practice to translate and culturally adapt mental health symptom scales or other global mental health tools.

Cost-Effectiveness of Digital Mental Health Versus Usual Care During Humanitarian Crises in Lebanon: Pragmatic Randomized Trial

BACKGROUND

There is evidence from meta-analyses and systematic reviews that digital mental health interventions for depression, anxiety, and stress-related disorders tend to be cost-effective. However, no such evidence exists for guided digital mental health care in low and middle-income countries (LMICs) facing humanitarian crises, where the needs are highest. Step-by-Step (SbS), a digital mental health intervention for depression, anxiety, and stress-related disorders, proved to be effective for Lebanese citizens and war-affected Syrians residing in Lebanon. Assessing the cost-effectiveness of SbS is crucial because Lebanon's overstretched health care system must prioritize cost-effective treatment options in the face of continuing humanitarian and economic crises.

OBJECTIVE

This study aims to assess the cost-effectiveness of SbS in a randomized comparison with enhanced usual care (EUC).

METHODS

The cost-effectiveness analysis was conducted alongside a pragmatic randomized controlled trial in 2 parallel groups comparing SbS (n=614) with EUC (n=635). The primary outcome was cost (in US $ for the reference year 2019) per treatment response of depressive symptoms, defined as >50% reduction of depressive symptoms measured using the Patient Health Questionnaire (PHQ). The secondary outcome was cost per remission of depressive symptoms, defined as a PHQ score <5 at last follow-up (5 months post baseline). The evaluation was conducted first from the health care perspective then from the societal perspective.

RESULTS

Taking the health care perspective, SbS had an 80% probability to be regarded as cost-effective compared with EUC when there is a willingness to pay US $220 per additional treatment response or US $840 per additional remission. Taking the wider societal perspective, SbS had a >75% probability to be cost-saving while gaining response or remission.

CONCLUSIONS

To our knowledge, this study is the first cost-effectiveness analysis based on a large randomized controlled trial (n=1249) of a guided digital mental health intervention in an LMIC. From the principal findings, 2 implications flowed, from the (1) health care perspective and (2) wider societal perspective. First, our findings suggest that SbS is associated with greater health benefits, albeit for higher costs than EUC. It is up to decision makers in health care to decide if they find the balance between additional health gains and additional health care costs acceptable. Second, as seen from the wider societal perspective, there is a substantial likelihood that SbS is not costing more than EUC but is associated with cost-savings as SBS participants become more productive, thus offsetting their health care costs. This finding may suggest to policy makers that it is in the interest of both population health and the wider Lebanese economy to implement SbS on a wide scale. In brief, SbS may offer a scalable, potentially cost-saving response to humanitarian emergencies in an LMIC.

Adapting brief problem-solving therapy for pregnant women experiencing depressive symptoms and intimate partner violence in rural Ethiopia

OBJECTIVE

To adapt an evidence-based psychological intervention for pregnant women experiencing depressive symptoms and intimate partner violence (IPV) in rural Ethiopia.

METHOD

We conducted a desk review of contextual factors in Sodo, Ethiopia, followed by qualitative interviews with 16 pregnant women and 12 antenatal care (ANC) providers. We engaged stakeholders through participatory theory of change (ToC) workshops, to select the intervention and articulate a programme theory. We used "ADAPT" guidance to adapt the intervention to the context, before mapping potential harms in a "dark logic model".

RESULTS

Brief problem-solving therapy developed for South Africa was the most contextually relevant model. We adapted the delivery format (participants prioritised confidentiality and brevity) and training and supervision (addressing IPV). Consensus long-term outcomes in our ToC were ANC providers skilled in detecting and responding to emotional difficulties and IPV, women receiving appropriate support, and emotional difficulties improving. Our dark logic model highlighted the risk of more severe IPV and mental health symptoms not being referred appropriately.

CONCLUSION

Although intervention adaptation is recommended, the process is rarely reported in depth. We comprehensively describe how contextual considerations, stakeholder engagement, programme theory, and adaptation can tailor psychological interventions for the target population in a low-income, rural setting.

Designing an App to Support Measurement-Based Peer Supervision of Frontline Health Workers Delivering Brief Psychosocial Interventions in Texas: Multimethod Study

BACKGROUND

The unmet need for mental health care affects millions of Americans. A growing body of evidence in implementation science supports the effectiveness of task sharing in the delivery of brief psychosocial interventions. The digitization of training and processes supporting supervision can rapidly scale up task-shared interventions and enable frontline health workers (FLWs) to learn, master, and deliver interventions with quality and support.

OBJECTIVE

We aimed to assess the perceived feasibility and acceptability of a novel mobile and web app designed and adapted to support the supervision, training, and quality assurance of FLWs delivering brief psychosocial interventions.

METHODS

We followed human-centered design principles to adapt a prototype app for FLWs delivering brief psychosocial interventions for depression, drawing from an app previously designed for use in rural India. Using a multimethod approach, we conducted focus group sessions comprising usability testing and group interviews with FLWs recruited from a large health system in Texas to assess the feasibility and acceptability of the app. The positive System Usability Scale was used to determine the app's overall usability. We also calculated the participants' likelihood of recommending the app to others using ratings of 0 to 10 from least to most likely (net promoter score). Focus group transcripts were coded and analyzed thematically, and recommendations were summarized across 4 key domains.

RESULTS

A total of 18 FLWs varying in role and experience with client care participated in the study. Participants found the app to be usable, with an average System Usability Scale score of 72.5 (SD 18.1), consistent with the industry benchmark of 68. Participants' likelihood of recommending the app ranged from 5 to 10, yielding a net promoter score of 0, indicating medium acceptability. Overall impressions of the app from participants were positive. Most participants (15/18, 83%) found the app easy to access and navigate. The app was considered important to support FLWs in delivering high-quality mental health care services. Participants felt that the app could provide more structure to FLW training and supervision processes through the systematic collection and facilitation of performance-related feedback. Key concerns included privacy-related and time constraints regarding implementing a separate peer supervision mechanism that may add to FLWs' workloads.

CONCLUSIONS

We designed, built, and tested a usable, functional mobile and web app prototype that supports FLW-delivered psychosocial interventions in the United States through a structured supervision mechanism and systematic collection and review of performance measures. The app has the potential to scale the work of FLWs tasked with delivering these interventions to the hardest-to-reach communities they serve. The results of this project will inform future work to evaluate the app's use and efficacy in real-world settings to support task-shared mental health programs across the United States.

Cultural adaptation of INDIGO mental health stigma reduction interventions using an ecological validity model in north India

Background

The International Study of Discrimination and Stigma Outcomes (INDIGO) Partnership is a multi-country international research program in seven sites across five low- and middle-income countries (LMICs) in Africa and Asia to develop, contextually adapt mental health stigma reduction interventions and pilot these among a variety of target populations. The aim of this paper is to report on the process of culturally adapting these interventions in India using an established framework.

Methods

As part of this larger program, we have contextualized and implemented these interventions from March 2022 to August 2023 in a site in north India. The Ecological Validity Model (EVM) was used to guide the adaptation and contextualization process comprising eight dimensions.

Findings

Six dimensions of the Ecological Validity Model were adapted, namely language, persons, metaphors, content, methods, and context; and two dimensions, namely concepts and goals, were retained.

Conclusion

Stigma reduction strategies with varied target groups, based on culturally appropriate adaptations, are more likely to be acceptable to the stakeholders involved in the intervention, and to be effective in terms of the program impact.

Effectiveness of a supportive care program via a smartphone application on the quality of life and care burden among family caregivers of patients with major depressive disorder: a randomized controlled trial

BACKGROUND

The majority of patients with major depressive disorder require care that has generally affected caregivers' lives. Providing care could cause negative experiences as a care burden and deteriorate quality of life. However, there is a lack of evidence about caregiver training-based informatics and its impact on the caregiver's life.

METHODS

This experimental study was carried out in Mashhad, Iran. A total of 60 primary family caregivers of patients with major depressive disorder were included in the study between February and July 2021. The quadruple block randomization method was used to allocate the participants into control and intervention groups. In the intervention group, family caregivers used the application with weekly phone calls for one month. The app contains the most important points of patient care and has the possibility of communicating with the nurse. The Novak and Guest Care Burden Inventory and the short form of the World Health Organization Quality of Life Questionnaire were completed before and after the intervention. Data analysis was performed using chi-squared tests, independent sample t tests, and analysis of covariance.

RESULTS

At baseline, the mean scores of care burden and quality of life were homogeneous between the two groups. After the intervention, the mean scores of care burden and quality of life were significantly reduced and improved in the intervention group compared with the control group (p < 0.001).

CONCLUSIONS

Using the application with the ability to communicate with the caregiver, along with educational support, helps to strengthen the relationship between the family caregiver and the nurse. Despite the effectiveness of the present intervention, before including this form of implementation of support in care programs, it is necessary to evaluate its other positive aspects in future studies.

Effectiveness of psychosocial interventions on the psychological outcomes of parents with preterm infants: A systematic review and meta-analysis

BACKGROUND

Parents of preterm infants are often thrown unexpectedly into the care of their vulnerable infant, causing them to be stressed and overwhelmed. Social support has been previously highlighted as a crucial factor in helping parents cope with stress. Several psychosocial interventions have thus been developed to support parents of preterm babies, which warrant further investigations.

OBJECTIVES

To evaluate the effectiveness of psychosocial interventions in reducing stress (primary outcome), anxiety, depression, pediatric medical traumatic stress (PMTS) and increasing social support among parents with preterm infants.

METHODS

A systematic-review and meta-analysis were conducted. Eight electronic databases were searched for relevant studies from their respective inception dates till September 2023. Meta-analysis was performed with RevMan, using the random-effects model. Heterogeneity was investigated using Cochran Q and I2 tests, and publication bias was assessed using funnel plots. Subgroup analyses were conducted for follow-up measurement, gender of parent, type of intervention provider, and setting.

FINDINGS

Eighteen studies were included in this review, and all studies were meta-analysed. Participants who received psychosocial interventions reported significantly lower stress and depression in comparison to control group participants. Psychosocial interventions delivered by psychologists and trained researchers were more effective compared to the nurses. The GRADE assessment indicated that the certainty of evidence for all outcomes were very low.

CONCLUSION

Psychosocial interventions effectively reduce stress and depression levels in parents with preterm infants. Our findings encourage the implementation of psychosocial interventions to improve parental psychological wellbeing. Future higher quality trials are needed to measure psychological outcomes among parents, especially fathers.

Psychotherapy for adult depression in low- and middle-income countries: an updated systematic review and meta-analysis

Previous meta-analyses on psychotherapy for adult depression have found a larger treatment effect in non-Western trials compared to Western trials (i.e. North America, Europe, and Australia). However, factors contributing to this difference remain unclear. This study investigated different study characteristics between Western and non-Western trials and examined their association with effect size estimates. We systematically searched PubMed, PsycINFO, Embase, and Cochrane Library (01-09-2022). We included randomized-controlled trials (RCTs) that compared psychotherapy with a control condition. The validity of included RCTs was assessed by the Cochrane risk of bias assessment tool (RoB 1). Effect sizes were pooled using the random-effects model. Subgroup analyses and meta-regressions were also conducted. We identified 405 eligible trials, among which 105 trials (117 comparisons, 16 304 participants) were from non-Western countries. We confirmed that non-Western trials had a larger treatment effect (g = 1.10, 95% CI 0.90-1.31) than Western trials (g = 0.57, 95% CI 0.52-0.62). Trials from non-Western countries also had more usual care controls, higher risk of bias, larger sample sizes, lower mean ages, younger adults, more group-based interventions, and other recruitment methods (e.g. systematic screening; p < 0.05). The larger effect sizes found in non-Western trials were related to the presence of wait-list controls, high risk of bias, cognitive-behavioral therapy, and clinician-diagnosed depression (p < 0.05). The larger treatment effects observed in non-Western trials may result from the high heterogeneous study design and relatively low validity. Further research on long-term effects, adolescent groups, and individual-level data are still needed.

Primary-level and community worker interventions for the prevention of mental disorders and the promotion of well-being in low- and middle-income countries

BACKGROUND

There is a significant research gap in the field of universal, selective, and indicated prevention interventions for mental health promotion and the prevention of mental disorders. Barriers to closing the research gap include scarcity of skilled human resources, large inequities in resource distribution and utilization, and stigma.

OBJECTIVES

To assess the effectiveness of delivery by primary workers of interventions for the promotion of mental health and universal prevention, and for the selective and indicated prevention of mental disorders or symptoms of mental illness in low- and middle-income countries (LMICs). To examine the impact of intervention delivery by primary workers on resource use and costs.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, Global Index Medicus, PsycInfo, WHO ICTRP, and ClinicalTrials.gov from inception to 29 November 2021.

SELECTION CRITERIA

Randomized controlled trials (RCTs) of primary-level and/or community health worker interventions for promoting mental health and/or preventing mental disorders versus any control conditions in adults and children in LMICs.

DATA COLLECTION AND ANALYSIS

Standardized mean differences (SMD) or mean differences (MD) were used for continuous outcomes, and risk ratios (RR) for dichotomous data, using a random-effects model. We analyzed data at 0 to 1, 1 to 6, and 7 to 24 months post-intervention. For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥ 0.80 large clinical effects. We evaluated the risk of bias (RoB) using Cochrane RoB2.

MAIN RESULTS

Description of studies We identified 113 studies with 32,992 participants (97 RCTs, 19,570 participants in meta-analyses) for inclusion. Nineteen RCTs were conducted in low-income countries, 27 in low-middle-income countries, 2 in middle-income countries, 58 in upper-middle-income countries and 7 in mixed settings. Eighty-three RCTs included adults and 30 RCTs included children. Cadres of primary-level workers employed primary care health workers (38 studies), community workers (71 studies), both (2 studies), and not reported (2 studies). Interventions were universal prevention/promotion in 22 studies, selective in 36, and indicated prevention in 55 RCTs. Risk of bias The most common concerns over risk of bias were performance bias, attrition bias, and reporting bias. Intervention effects 'Probably', 'may', or 'uncertain' indicates 'moderate-', 'low-', or 'very low-'certainty evidence. *Certainty of the evidence (using GRADE) was assessed at 0 to 1 month post-intervention as specified in the review protocol. In the abstract, we did not report results for outcomes for which evidence was missing or very uncertain. Adults Promotion/universal prevention, compared to usual care: - probably slightly reduced anxiety symptoms (MD -0.14, 95% confidence interval (CI) -0.27 to -0.01; 1 trial, 158 participants) - may slightly reduce distress/PTSD symptoms (SMD -0.24, 95% CI -0.41 to -0.08; 4 trials, 722 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD -0.69, 95% CI -1.08 to -0.30; 4 trials, 223 participants) Indicated prevention, compared to usual care: - may reduce adverse events (1 trial, 547 participants) - probably slightly reduced functional impairment (SMD -0.12, 95% CI -0.39 to -0.15; 4 trials, 663 participants) Children Promotion/universal prevention, compared to usual care: - may improve the quality of life (SMD -0.25, 95% CI -0.39 to -0.11; 2 trials, 803 participants) - may reduce adverse events (1 trial, 694 participants) - may slightly reduce depressive symptoms (MD -3.04, 95% CI -6 to -0.08; 1 trial, 160 participants) - may slightly reduce anxiety symptoms (MD -2.27, 95% CI -3.13 to -1.41; 1 trial, 183 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD 0, 95% CI -0.16 to -0.15; 2 trials, 638 participants) - may slightly reduce anxiety symptoms (MD 4.50, 95% CI -12.05 to 21.05; 1 trial, 28 participants) - probably slightly reduced distress/PTSD symptoms (MD -2.14, 95% CI -3.77 to -0.51; 1 trial, 159 participants) Indicated prevention, compared to usual care: - decreased slightly functional impairment (SMD -0.29, 95% CI -0.47 to -0.10; 2 trials, 448 participants) - decreased slightly depressive symptoms (SMD -0.18, 95% CI -0.32 to -0.04; 4 trials, 771 participants) - may slightly reduce distress/PTSD symptoms (SMD 0.24, 95% CI -1.28 to 1.76; 2 trials, 448 participants).

AUTHORS' CONCLUSIONS

The evidence indicated that prevention interventions delivered through primary workers - a form of task-shifting - may improve mental health outcomes. Certainty in the evidence was influenced by the risk of bias and by substantial levels of heterogeneity. A supportive network of infrastructure and research would enhance and reinforce this delivery modality across LMICs.

Digital interventions for common mental disorders in low- and middle-income countries: A systematic review and meta-analysis

Background

In low-resource settings, e-mental health may substantially increase access to evidence-based interventions for common mental disorders. We conducted a systematic literature search to identify randomised trials examining the effects of digital interventions with or without therapeutic guidance compared to control conditions in individuals with anxiety and/or depression symptoms in low- and middle-income countries (LMICs).

Methods

The main outcome was the reduction in symptoms at the post-test. Secondary outcomes included improvements in quality of life and longer-term effects (≥20 weeks post-randomisation). The effect size Hedges' g was calculated using the random effects model.

Results

A total of 21 studies (23 comparisons) with 5.296 participants were included. Digital interventions were more effective than controls in reducing symptoms of common mental disorders at the post-test (g = -0.89, 95% confidence interval [CI] -1.26 to -0.52, p < 0.001; NNT = 2.91). These significant effects were confirmed when examining depressive (g = -0.77, 95% CI -1.11; -0.44) and anxiety symptoms separately (g = -1.02, 95% CI -1.53 to -0.52) and across all other sensitivity analyses. Digital interventions also resulted in a small but significant effect in improving quality of life (g = 0.32, 95% CI 0.19 to 0.45) at the post-test. Over the longer term, the effects were smaller but remained significant for all examined outcomes. Heterogeneity was moderate to high in all analyses. Subgroup and meta-regression analyses did not result in significant outcomes in any of the examined variables (e.g., guided vs. unguided interventions).

Conclusions

Digital interventions, with or without guidance, may effectively bridge the gap between treatment supply and demand in LMICs. Nevertheless, more studies are needed to draw firm conclusions regarding the magnitude of the effects of digital interventions.

Assessing ad-hoc adaptations' alignment with therapeutic goals: a qualitative study of lay counselor-delivered family therapy in Eldoret, Kenya

BACKGROUND

A key question in implementation science is how to balance adaptation and fidelity in translating interventions to new settings. There is growing consensus regarding the importance of planned adaptations to deliver interventions in contextually sensitive ways. However, less research has examined ad-hoc adaptations, or those that occur spontaneously in the course of intervention delivery. A key question is whether ad-hoc adaptations ultimately contribute to or detract from intervention goals. This study aimed to (a) identify ad-hoc adaptations made during delivery of a family therapy intervention and (b) assess whether they promoted or interrupted intervention goals.

METHODS

Tuko Pamoja (Swahili: "We are Together") is an evidence-informed family therapy intervention aiming to improve family dynamics and mental health in Kenya. Tuko Pamoja employs a task-shifting model, delivered by lay counselors who are afforded a degree of flexibility in presenting content and in practices they use in sessions. We used transcripts of therapy sessions with 14 families to examine ad-hoc adaptations used by counselors. We first identified and characterized ad-hoc adaptations through a team-based code development, coding, and code description process. Then, we evaluated to what extent ad-hoc adaptations promoted the principles and strategies of the intervention ("TP-promoting"), disrupted them ("TP-interrupting"), or neither ("TP-neutral"). To do this, we first established inter-coder agreement on application of these categories with verification by the intervention developer. Then, coders categorized ad-hoc adaptation text segments as TP-promoting, TP-interrupting, or TP-neutral.

RESULTS

Ad-hoc adaptations were frequent and included (in decreasing order): incorporation of religious content, exemplars/role models, community dynamics and resources, self-disclosure, and metaphors/proverbs. Ad-hoc adaptations were largely TP-promoting (49%) or neutral (39%), but practices were TP-interrupting 12% of the time. TP-interrupting practices most often occurred within religious content and exemplars/role models, which were also the most common practices overall.

CONCLUSION

Extra attention is needed during planned adaptation, training, and supervision to promote intervention-aligned use of common ad-hoc adaptation practices. Discussing them in trainings can provide guidance for lay providers on how best to incorporate ad-hoc adaptations during delivery. Future research should evaluate whether well-aligned ad-hoc adaptations improve therapeutic outcomes.

Psychological treatment of depression: A systematic overview of a 'Meta-Analytic Research Domain'

BACKGROUND

Over the past 16 years, we have developed a 'Meta-analytic Research Domain' (MARD) of all randomized trials of psychological treatments of depression. A MARD is a living systematic review of a research field, that cannot be otherwise covered by one (network) meta-analysis and includes multiple PICOs. In this paper we give an overview of the findings of this MARD.

METHODS

A narrative review of the results of the 118 meta-analyses on psychotherapies for depression that were published within our MARD.

RESULTS

Most research has been conducted on cognitive-behavioral therapy (CBT), but several other psychotherapies are also effective, with few differences between therapies. They can be effectively delivered in individual, group, telephone and guided self-help format and are effective in many different target groups and across different age groups, although the effects are significantly smaller in children and adolescents. Psychotherapies have comparable effects as pharmacotherapy at the short term but are probably more effective at the longer term. Combined treatment is more effective than either psychotherapy or pharmacotherapy alone at the short, but also at the longer term.

LIMITATIONS

We did not summarize all published meta-analyses (protocols, methodological studies) and have not compared our results to those found in other meta-analyses on comparable subjects.

CONCLUSION

Psychotherapies can contribute considerably to a reduction of the disease burden of depression. MARDs are an important next step in the aggregation of knowledge from randomized controlled trials in psychological treatments of depression as well as in other healthcare sectors.

Health status and quality of life in comorbid physical multimorbidity and depression among adults aged ⩾50 years from low- and middle-income countries

BACKGROUND

Data on the clinical and functional significance of comorbid depression in physical multimorbidity in middle-aged and older adults and from low- and middle-income countries (LMICs) are lacking.

AIMS

This study aims to determine the association of comorbid depression in physical multimorbidity with health outcomes and quality of life among adults aged ⩾50 years from six LMICs.

METHODS

Cross-sectional, nationally representative data from the Study on Global Ageing and Adult Health were analyzed. DSM-IV Depression was based on past 12-month symptoms. Eleven chronic physical conditions were assessed. Health status was based on scales ranging from 0 (best) to 100 (worse). The quality of life (8-item WHO Quality of Life) scale ranged from 0 (worse) to 100 (best). Multivariable linear regression analyses were conducted.

RESULTS

Data on 34,129 individuals aged ⩾50 years [mean (SD) age 62.4 (16.0) years; 52.1% females] were analyzed. Among people with physical multimorbidity, having comorbid depression was associated with significantly worse health status in terms of sleep/energy (β = 14.71: 95% CI [12.23, 17.20]), self-care (13.23: [8.66, 17.82]), pain/discomfort (13.03: [9.59, 16.47]), mobility (11.06: [6.91, 15.21]), cognition (10.41: [7.31, 13.50]), perceived stress (8.35: [4.71, 11.99]), interpersonal activities (7.81: [3.71, 11.91]), and lower quality of life (-8.81: [-10.74, -6.88]).

CONCLUSIONS

Comorbid depression in physical multimorbidity was associated with lower quality of life and poorer scores in multiple domains of health status. Treatment of depression in people with physical multimorbidity may potentially lead to better clinical outcomes, but future studies are needed to determine the most effective intervention to address this comorbidity in LMICs.

An Online Mindfulness Intervention for International Students: A Randomized Controlled Feasibility Trial

Background

Student mobility across borders poses challenges to health systems at the university and country levels. International students suffer from stress more than their local peers, however, do not seek help or underutilize existing help offers. Some barriers to help-seeking among international students are insufficient information regarding the health offers, stigma, and language, which might be overcome via culturally adapted internet and mobile-based interventions (IMI).

Method

A randomized controlled feasibility trial with a parallel design assessed the feasibility and potential efficacy of an online mindfulness intervention adapted for international university students. Participants were randomized into either an adapted online mindfulness intervention (StudiCareM-E) (IG, n = 20) or a waitlist control group (WL, n = 20). Participants were assessed at baseline (t0) and eight-week post-randomization (t1). The feasibility of StudiCareM-E was evaluated regarding intervention adherence, client satisfaction, and potential negative effects. The potential efficacy of StudiCareM-E was measured by means of the level of mindfulness, perceived stress, depression, anxiety, presenteeism, and wellbeing. Efficacy outcomes were evaluated with regression models on the intention-to-treat (ITT) sample (n = 40), adjusting for the baseline values.

Results

Participants' formative feedback suggested improvements in the content of the IMI. There were no crucial negative effects compared to WL. Assessment dropout was 35% (IG: 50%: WL: 20%), and intervention dropout was 60%. StudiCareM-E yielded significant improvements in mindfulness (β = .34), well-being (β = .37), and anxiety (β = -.42) compared to WL.

Conclusion

StudiCareM-E might be used among culturally diverse international student populations to improve their well-being. Future studies might carefully inspect the extent of the adaptation needs of their target group and design their interventions accordingly.

Study protocol of DIVERGE, the first genetic epidemiological study of major depressive disorder in Pakistan

INTRODUCTION

Globally, 80% of the burdenof major depressive disorder (MDD) pertains to low- and middle-income countries. Research into genetic and environmental risk factors has the potential to uncover disease mechanisms that may contribute to better diagnosis and treatment of mental illness, yet has so far been largely limited to participants with European ancestry from high-income countries. The DIVERGE study was established to help overcome this gap and investigate genetic and environmental risk factors for MDD in Pakistan.

METHODS

DIVERGE aims to enrol 9000 cases and 4000 controls in hospitals across the country. Here, we provide the rationale for DIVERGE, describe the study protocol and characterise the sample using data from the first 500 cases. Exploratory data analysis is performed to describe demographics, socioeconomic status, environmental risk factors, family history of mental illness and psychopathology.

RESULTS AND DISCUSSION

Many participants had severe depression with 74% of patients who experienced multiple depressive episodes. It was a common practice to seek help for mental health struggles from faith healers and religious leaders. Socioeconomic variables reflected the local context with a large proportion of women not having access to any education and the majority of participants reporting no savings.

CONCLUSION

DIVERGE is a carefully designed case-control study of MDD in Pakistan that captures diverse risk factors. As the largest genetic study in Pakistan, DIVERGE helps address the severe underrepresentation of people from South Asian countries in genetic as well as psychiatric research.

Psychotherapy for comorbid depression and somatic disorders: a systematic review and meta-analysis

BACKGROUND

The treatment of depression in patients with somatic disorders is crucial, given its negative impact on quality of life (QoL), functioning, and even on the somatic disease prognosis. We aimed to examine the most updated evidence on the effects of psychotherapy in patients with depression and somatic disorders, including HIV, oncological, cardiometabolic, and neurological disorders.

METHODS

We conducted a meta-analysis of 75 randomized trials (8209 participants) of psychotherapy for adults with somatic disorders and a diagnosis or elevated symptoms of depression. Outcomes included depression, QoL, somatic health-related outcomes, and mortality.

RESULTS

Psychotherapy significantly reduced the severity of depression at post-treatment across all categories of somatic disorders (Hedges'g = 0.65; 95% CI 0.52-0.79), with sustained effects at 6-11 months (g = 0.38; 95% CI 0.22-0.53) and at 12 months follow-up or longer (g = 0.13; 95% CI 0.04-0.21). Psychotherapy also showed significant effects on QoL (g = 0.26; 95% CI 0.17-0.35), maintained up to 11 months follow-up (g = 0.25; 95% CI 0.16-0.34). No significant effects were observed on the most frequently reported somatic health-related outcomes (glycemic control, pain), and neither on mortality. Heterogeneity in most analyses was very high, and only 29 (38%) trials were rated at low risk of bias (RoB).

CONCLUSIONS

Psychotherapy may be an effective treatment option for patients with depression and somatic disorders, with long-term effects on depression severity and QoL. However, these results should be interpreted with caution due to heterogeneity and RoB.

Psychological treatment of perinatal depression: a meta-analysis

BACKGROUND

Depression during pregnancy and after the birth of a child is highly prevalent and an important public health problem. Psychological interventions are the first-line treatment and, although a considerable number of randomized trials have been conducted, no recent comprehensive meta-analysis has evaluated treatment effects.

METHODS

We used an existing database of randomized controlled trials of psychotherapies for adult depression and included studies aimed at perinatal depression. Random effects models were used in all analyses. We examined the effects of the interventions in the short and long term, and also examined secondary outcomes.

RESULTS

Forty-three studies with 49 comparisons and 6270 participants between an intervention and control group were included. The overall effect size was g = 0.67 [95% confidence interval (CI) 0.45~0.89; numbers needed-to-be-treated = 4.39] with high heterogeneity (I2 = 80%; 95% CI 75~85). This effect size remained largely unchanged and significant in a series of sensitivity analyses, although some publication bias was found. The effects remained significant at 6-12 months follow-up. Significant effects were also found for social support, anxiety, functional limitations, parental stress and marital stress, although the number of studies for each outcome was low. All results should be considered with caution because of the high levels of heterogeneity in most analyses.

CONCLUSIONS

Psychological interventions are probably effective in the treatment of perinatal depression, with effects that last at least up to 6-12 months and probably also have effects on social support, anxiety, functional impairment, parental stress, and marital stress.

Two decades of digital interventions for anxiety disorders: a systematic review and meta-analysis of treatment effectiveness

BACKGROUND

Digital interventions for anxiety disorders are a promising solution to address barriers to evidence-based treatment access. Precise and powerful estimates of digital intervention effectiveness for anxiety disorders are necessary for further adoption in practice. The present systematic review and meta-analysis examined the effectiveness of digital interventions across all anxiety disorders and specific to each disorder v. wait-list and care-as-usual controls.

METHODS

A systematic search of bibliographic databases identified 15 030 abstracts from inception to 1 January 2020. Forty-seven randomized controlled trials (53 comparisons; 4958 participants) contributed to the meta-analysis. Subgroup analyses were conducted by an anxiety disorder, risk of bias, treatment support, recruitment, location and treatment adherence.

RESULTS

A large, pooled effect size of g = 0.80 [95% Confidence Interval: 0.68-0.93] was found in favor of digital interventions. Moderate to large pooled effect sizes favoring digital interventions were found for generalized anxiety disorder (g = 0.62), mixed anxiety samples (g = 0.68), panic disorder with or without agoraphobia (g = 1.08) and social anxiety disorder (g = 0.76) subgroups. No subgroups were significantly different or related to the pooled effect size. Notably, the effects of guided interventions (g = 0.84) and unguided interventions (g = 0.64) were not significantly different. Supplemental analysis comparing digital and face-to-face interventions (9 comparisons; 683 participants) found no significant difference in effect [g = 0.14 favoring digital interventions; Confidence Interval: -0.01 to 0.30].

CONCLUSION

The precise and powerful estimates found further justify the application of digital interventions for anxiety disorders in place of wait-list or usual care.

Meta-analysis: The Effectiveness of Youth Psychotherapy Interventions in Low- and Middle-Income Countries

OBJECTIVE

Because most youth psychotherapies are developed and tested in high-income countries, relatively little is known about their effectiveness or moderators in low- and middle-income countries (LMICs). To address this gap, we conducted a meta-analysis of randomized controlled trials (RCTs) testing psychotherapies for youth with multiple psychiatric conditions in LMICs, and we tested candidate moderators.

METHOD

We searched 9 international databases for RCTs of youth psychotherapies in LMICs published through January 2021. The RCTs targeted elevated symptoms of youth anxiety (including post-traumatic stress disorder [PTSD] and obsessive-compulsive disorder), depression, conduct problems, and attention problems. Using robust variance estimation, we estimated the pooled effect sizes (Hedges g) at post treatment and follow-up for intervention vs control conditions.

RESULTS

Of 5,145 articles identified, 34 articles (with 43 treatment-control comparisons and 4,176 participants) met methodological standards and were included. The overall pooled g with winsorized outliers was 1.01 (95% CI = 0.72-1.29, p < .001) at post treatment and 0.68 (95% CI = 0.29-1.07, p = .003) at follow-up. Interventions delivered by professional clinicians significantly outperformed those delivered by lay providers (g = 1.59 vs 0.53), but all interventions for conduct problems were delivered by professionals, and the difference for interventions targeting internalizing problems (g = 1.33 vs .53) was not significant. Interventions developed non-locally were more effective if they were not adapted to local contexts than if they were adapted locally (g = 2.31 vs 0.66), highlighting a need for further research on effective adaptations. Significant risk of bias was identified.

CONCLUSION

Overall, pooled effects of youth psychotherapies in LMICs were markedly larger than those in recent comparable non-LMIC meta-analyses, which have shown small-to-medium effects for youth psychotherapies. Findings highlight the potential benefits of youth psychotherapies in LMICs, as well as a need for more RCTs and improved study quality.

Guided digital health intervention for depression in Lebanon: randomised trial

BACKGROUND

Most people with mental disorders in communities exposed to adversity in low-income and middle-income countries (LMICs) do not receive effective care. Digital mental health interventions are scalable when digital access is adequate, and can be safely delivered during the COVID-19 pandemic.

OBJECTIVE

To examine the effects of a new WHO-guided digital mental health intervention, Step-by-Step, supported by a non-specialist helper in Lebanon, in the context of concurring economic, humanitarian and political crises, a large industrial disaster and the COVID-19 pandemic.

METHODS

We conducted a single-blind, two-arm pragmatic randomised trial, comparing guided Step-by-Step with enhanced care as usual (ECAU) among people suffering from depression and impaired functioning. Primary outcomes were depression (Patient Health Questionnaire 9 (PHQ-9)) and impaired functioning (WHO Disability Assessment Schedule-12 (WHODAS)) at post-treatment.

FINDINGS

680 people with depression (PHQ-9>10) and impaired functioning (WHODAS>16) were randomised to Step-by-Step or ECAU. Intention-to-treat analyses showed effects on depression (standardised mean differences, SMD: 0.71; 95% CI: 0.45 to 0.97), impaired functioning (SMD: 0.43; 95% CI: 0.21 to 0.65), post-traumatic stress (SMD: 0.53; 95% CI: 0.27 to 0.79), anxiety (SMD: 0.74; 95% CI: 0.49 to 0.99), subjective well-being (SMD: 0.37; 95% CI: 0.12 to 0.62) and self-identified personal problems (SMD: 0.56; 95% CI 0.29 to 0.83). Significant effects on all outcomes were retained at 3-month follow-up.

CONCLUSIONS

Guided digital mental health interventions can be effective in the treatment of depression in communities exposed to adversities in LMICs, although some uncertainty remains because of high attrition.

CLINICAL IMPLICATIONS

Guided digital mental health interventions should be considered for implementation in LMICs.

What matters in mental health care? A co-design approach to developing clinical supervision tools for practitioner competency development

Background

Specialised mental health (MH) care providers are often absent or scarcely available in low resource and humanitarian settings (LRHS), making MH training and supervision for general health care workers (using task-sharing approaches) essential to scaling up services and reducing the treatment gap for severe and common MH conditions. Yet, the diversity of settings, population types, and professional skills in crisis contexts complicate these efforts. A standardised, field tested instrument for clinical supervision would be a significant step towards attaining quality standards in MH care worldwide.

Methods

A competency-based clinical supervision tool was designed by Médecins Sans Frontières (MSF) for use in LRHS. A systematic literature review informed its design and assured its focus on key clinical competencies. An initial pool of behavioural indicators was identified through a rational theoretical scale construction approach, tested through waves of simulation and reviewed by 12 MH supervisors in seven projects where MSF provides care for severe and common MH conditions.

Results

Qualitative analysis yielded two sets of competency grids based on a supervisee's professional background: one for 'psychological/counselling' and another for 'psychiatric/mhGAP' practitioners. Each grid features 22-26 competencies, plus optional items for specific interventions. While the structure and content were assessed as logical by supervisors, there were concerns regarding the adequacy of the tool to field reality.

Conclusions

Humanitarian settings have specific needs that require careful consideration when developing capacity-building strategies. Clinical supervision of key competencies through a standardised instrument represents an important step towards ensuring progress of clinical skills among MH practitioners.

School-based group interpersonal therapy for adolescents with depression in rural Nepal: a mixed methods study exploring feasibility, acceptability, and cost

Background

Adolescents with depression need access to culturally relevant psychological treatment. In many low- and middle-income countries treatments are only accessible to a minority. We adapted group interpersonal therapy (IPT) for adolescents to be delivered through schools in Nepal. Here we report IPT's feasibility, acceptability, and cost.

Methods

We recruited 32 boys and 30 girls (aged 13-19) who screened positive for depression. IPT comprised of two individual and 12 group sessions facilitated by nurses or lay workers. Using a pre-post design we assessed adolescents at baseline, post-treatment (0-2 weeks after IPT), and follow-up (8-10 weeks after IPT). We measured depressive symptoms with the Depression Self-Rating Scale (DSRS), and functional impairment with a local tool. To assess intervention fidelity supervisors rated facilitators' IPT skills across 27/90 sessions using a standardised checklist. We conducted qualitative interviews with 16 adolescents and six facilitators post-intervention, and an activity-based cost analysis from the provider perspective.

Results

Adolescents attended 82.3% (standard deviation 18.9) of group sessions. All were followed up. Depression and functional impairment improved between baseline and follow-up: DSRS score decreased by 81% (95% confidence interval 70-95); functional impairment decreased by 288% (249-351). In total, 95.3% of facilitator IPT skills were rated superior/satisfactory. Adolescents found the intervention useful and acceptable, although some had concerns about privacy in schools. The estimate of intervention unit cost was US $96.9 with facilitators operating at capacity.

Conclusions

School-based group IPT is feasible and acceptable in Nepal. Findings support progression to a randomised controlled trial to assess effectiveness and cost-effectiveness.

Evaluation of competency-driven training for facilitators delivering a psychological intervention for children in Lebanon: a proof-of-concept study

AIMS

The mounting evidence for effective delivery of psychological interventions by non-specialists in low- and middle-income settings has led to a rapid expansion of mental health and psychosocial support trainings globally. As such, there is a demand for strategies on how to train and implement these services to attain adequate quality. This study aims to evaluate the added value of a competency-driven approach to training of facilitators for a group intervention for children with severe emotional distress in Lebanon.

METHODS

In a controlled before and after study, 24 trainees were randomly allocated to participate in either a competency-driven training (CDT) or training-as-usual (TAU) (1 : 1) for a psychological intervention for children with severe emotional distress. We assessed the change in demonstrated competencies, using standardised role-plays, before and after the training. Measures included the 13-item Working with children-Assessment of Competencies Tool (WeACT), the 15-item ENhancing Assessment of Common Therapeutic factors (ENACT) and the 6-item Group facilitation: Assessment of Competencies Tool (GroupACT). The trainer in the experimental arm used pre-training and during training competency assessment scores to make real-time adjustment to training delivery. Due to COVID-19 pandemic restrictions, all activities were done remotely.

RESULTS

CDT resulted in significantly better outcomes on increasing competencies on the WeACT (repeated measures analysis of variance; F_{(1, 22)} = 6.49, p < 0.018) and on the GroupACT (Mann-Whitney U = 22, p < 0.003), though not statistically significant on the ENACT. There is no significant between-group difference on the reduction of harmful behaviours, mainly because both forms of training appear equally successful in eliminating such behaviours.

CONCLUSIONS

This proof-of-concept study demonstrates the potential of CDT, using standardised assessment of trainee competencies, to contribute to better training outcomes without extending the duration of training. CDT can result in up to 18% greater increase in adequate competency, when compared to TAU. The study also yields recommendations for further enhancing the benefits of competency-driven strategies. A fully powered trial is needed to confirm these findings.

Fairburn C. EMPOWER: Toward the Global Dissemination of Psychosocial Interventions

Even before the COVID-19 pandemic, the needs for care of persons with mental illness remained largely unmet worldwide, testifying to the inadequacy of current approaches to mental health care and their unsuitability for the rising demand. One hurdle to improved access to quality care is the reliance on expensive specialist providers, particularly for the delivery of psychosocial interventions. This article describes EMPOWER, a not-for-profit program that builds on the clinical science demonstrating the effectiveness of brief psychosocial interventions for a range of psychiatric conditions; implementation science demonstrating the effectiveness of delivery of these interventions by non-specialist providers (NSPs); and pedagogical science demonstrating the effectiveness of digital approaches for training and quality assurance. The EMPOWER program leverages digital tools for training and supervising NSPs, designing competency-based curricula, assessing treatment-specific competencies, implementing measurement-based peer supervision for support and quality assurance, and evaluating impacts to enhance the effectiveness of the delivery system.

Effects of a WHO-guided digital health intervention for depression in Syrian refugees in Lebanon: A randomized controlled trial

BACKGROUND

Most displaced people with mental disorders in low- and middle-income countries do not receive effective care, and their access to care has deteriorated during the Coronavirus Disease 2019 (COVID-19) pandemic. Digital mental health interventions are scalable when digital access is adequate, and they can be safely delivered during the COVID-19 pandemic. We examined whether a new WHO-guided digital mental health intervention, Step-by-Step, in which participants were supported by a nonspecialist helper, was effective in reducing depression among displaced people in Lebanon.

METHODS AND FINDINGS

We conducted a single-blind, 2-arm pragmatic randomized clinical trial, comparing guided Step-by-Step with enhanced care as usual (ECAU) among displaced Syrians suffering from depression and impaired functioning in Lebanon. Primary outcomes were depression (Patient Health Questionnaire, PHQ-9) and impaired functioning (WHO Disability Assessment Schedule-12, WHODAS) at posttreatment. Secondary outcomes included subjective well-being, anxiety, post-traumatic stress, and self-described problems. A total of 569 displaced people from Syria with depression (PHQ-9 ≥ 10) and impaired functioning (WHODAS > 16) were randomized to Step-by-Step (N = 283; lost to follow-up: N = 167) or ECAU (N = 286; lost to follow-up: 133). Participants were considered to be lost to follow-up when they did not fill in the outcome measures at posttest or follow-up. Recruitment started on December 9, 2019 and was completed on July 9, 2020. The last follow-up assessments were collected in December 2020. The study team had access to the online platform, where they could see treatment arm assignment for each participant. All questionnaires were completed by participants online. Intention-to-treat (ITT) analyses showed intervention effects on depression (standardized mean differences [SMDs]: 0.48; 95% CI: 0.26; 0.70; p < 0.001), impaired functioning (SMD: 0.35; 95% CI: 0.14; 0.56; p < 0.001), post-traumatic stress (SMD: 0.36; 95% CI: 0.16; 0.56; p < 0.001), anxiety (SMD: 0.46; 95% CI: 0.24; 0.68; p < 0.001), subjective well-being (SMD: 0.47; 95% CI: 0.26; 0.68; p < 0.001), and self-identified personal problems (SMD: 0.49; 95% CI 0.28; 0.70; p < 0.001). Significant effects on all outcomes were maintained at 3 months follow-up. During the trial, one serious adverse event occurred, unrelated to the intervention. The main limitation of the current trial is the high dropout rate.

CONCLUSIONS

In this study, we found that a guided, digital intervention was effective in reducing depression in displaced people in Lebanon. The guided WHO Step-by-Step intervention we examined should be made available to communities of displaced people that have digital access.

Association of Task-Shared Psychological Interventions With Depression Outcomes in Low- and Middle-Income Countries: A Systematic Review and Individual Patient Data Meta-analysis

Importance

Task sharing, the training of nonspecialist workers with no formal experience in counseling, is a promising strategy for addressing the large gap in treatment for depression in low- and middle-income countries (LMICs).

Objective

To examine the outcomes and moderators of task-shared psychological interventions associated with depression severity, response, and remission.

Data Sources

Systematic literature searches in PubMed, Embase, PsycINFO, and Cochrane Library up to January 1, 2021.

Study Selection

Randomized clinical trials (RCTs) of task-shared psychological interventions compared with control conditions for adults with depressive symptoms in LMICs were included.

Data Extraction and Synthesis

Two researchers independently reviewed the titles, abstracts, and full text of articles from an existing generic meta-analytic database that includes all RCTs on psychotherapy for depression. A systematic review and individual patient data (IPD) meta-analysis was used to estimate the outcomes of task-shared psychological interventions across patient characteristics using mixed-effects models. Procedures for abstracting data and assessing data quality and validity followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline.

Main Outcomes and Measures

Primary outcome was reduction in depression symptom severity measured by the 9-item Patient Health Questionnaire (PHQ-9). Response and remission rates were also estimated.

Results

Of 13 eligible trials, 11 (4145 participants) contributed IPD. Task-shared psychological interventions were associated with a greater decrease in depressive symptom severity than control conditions (Hedges g, 0.32; 95% CI, -0.26 to -0.38). Participants in the intervention groups had a higher chance of responding (odds ratio, 2.11; 95% CI, 1.60 to 2.80) and remitting (odds ratio, 1.87; 95% CI, 1.20 to 1.99). The presence of psychomotor symptoms was significantly associated with the outcomes of task-shared psychological interventions (β [SE], -1.21 [0.39]; P = .002). No other significant associations were identified. Heterogeneity among the trials with IPD was 74% (95% CI, 53%-86%).

Conclusions and Relevance

In this meta-analysis of IPD, task-shared psychological interventions were associated with a larger reduction in depressive symptom severity and a greater chance of response and remission than control conditions. These findings show potential for the use of task-sharing of psychological interventions across different groups of patients with depression. Further research would help identify which people are most likely to benefit and strengthen larger-scale implementation of this strategy to address the burden of depression in LMICs.

The silent burden: a landscape analysis of common perinatal mental disorders in low- and middle-income countries

BACKGROUND

Mental health has long fallen behind physical health in attention, funding, and action-especially in low- and middle-income countries (LMICs). It has been conspicuously absent from global reproductive, maternal, newborn, child, and adolescent health (MNCAH) programming, despite increasing awareness of the intergenerational impact of common perinatal mental disorders (CPMDs). However, the universal health coverage (UHC) movement and COVID-19 have brought mental health to the forefront, and the MNCAH community is looking to understand how to provide women effective, sustainable care at scale. To address this, MOMENTUM Country and Global Leadership (MCGL) commissioned a landscape analysis in December 2020 to assess the state of CPMDs and identify what is being done to address the burden in LMICs.

METHODS

The landscape analysis (LA) used a multitiered approach. First, reviewers chose a scoping review methodology to search literature in PubMed, Google Scholar, PsychInfo, and Scopus. Titles and abstracts were reviewed before a multidisciplinary team conducted data extraction and analysis on relevant articles. Second, 44 key informant interviews and two focus group discussions were conducted with mental health, MNCAH, humanitarian, nutrition, gender-based violence (GBV), advocacy, and implementation research experts. Finally, reviewers completed a document analysis of relevant mental health policies from 19 countries.

RESULTS

The LA identified risk factors for CPMDs, maternal mental health interventions and implementation strategies, and remaining knowledge gaps. Risk factors included social determinants, such as economic or gender inequality, and individual experiences, such as stillbirth. Core components identified in successful perinatal mental health (PMH) interventions at community level included stepped care, detailed context assessments, task-sharing models, and talk therapy; at health facility level, they included pre-service training on mental health, trained and supervised providers, referral and assessment processes, mental health support for providers, provision of respectful care, and linkages with GBV services. Yet, significant gaps remain in understanding how to address CPMDs.

CONCLUSION

These findings illuminate an urgent need to provide CPMD prevention and care to women in LMICs. The time is long overdue to take perinatal mental health seriously. Efforts should strive to generate better evidence while implementing successful approaches to help millions of women "suffering in silence."

Preliminary results of adapting the stepped care model for depression management in Vietnam

BACKGROUND

Depression is the leading burden of mental disease, especially in low-and-middle-income countries like Vietnam. The Stepped Care Model is a promising approach to managing depression in the community with low resources. This is the first study that implemented the adapted Stepped Care Model for depression management in the Vietnamese context and evaluated the initial effectiveness of this community-based intervention in the Thai Nguyen community.

MATERIALS AND METHODS

A quasi-experimental study with a 3-month follow-up was conducted in 10 selected communes in Thai Nguyen province. The most important modifications in the Stepped Care Model for depression management were the screening focused on the high-risk individuals living in the community; the combination of 8-session group psychotherapy with animation activities at commune health stations (CHS); and using psychotherapy as first-line treatment. From August 2020 to January 2021, quantitative data were collected using the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form. The descriptive analyses were performed to describe the demographic characteristics and the change in the questionnaires' mean score at the baseline and 3-month follow-up.

RESULTS

A total of 1,891 people were approached in the community, of which 359 voluntary people met the study criteria and attended group psychotherapy. During group psychotherapy, the average PHQ-9 scores gradually decreased, and after the 8th session, this figure dropped by 2.65 times compared to the beginning. After 3 months, the percentage of the group with mild-moderate depression shrank from 95.5 to 9.3%, and there were no more severe cases. Moreover, life satisfaction increased by 32% and the anxiety level significantly dropped according to Q-LES-Q-SF and GAD-7 accordingly.

CONCLUSION

The preliminary results after 3-month follow-up showed that the Stepped Care Model with group psychotherapy at the CHS was promising to manage the depression in the community. This task shifting approach with limited resources should be further disseminated and studied for long-term effectiveness in low-and-middle-income countries like Vietnam.

Cost-effectiveness of psychological intervention within services for depression delivered by primary care workers in Nepal: economic evaluation of a randomized control trial

BACKGROUND

Integrating services for depression into primary care is key to reducing the treatment gap in low- and middle-income countries. We examined the value of providing the Healthy Activity Programme (HAP), a behavioral activation psychological intervention, within services for depression delivered by primary care workers in Chitwan, Nepal using data from the Programme for Improving Mental Health Care.

METHODS

People diagnosed with depression were randomized to receive either standard treatment (ST), comprised of psychoeducation, antidepressant medication, and home-based follow up, or standard treatment plus psychological intervention (T + P). We estimated incremental costs and health effects of T + P compared to ST, with quality adjusted life years (QALYs) and depression symptom scores over 12 months as health effects. Nonparametric uncertainty analysis provided confidence intervals around each incremental effectiveness ratio (ICER); results are presented in 2020 international dollars.

RESULTS

Sixty participants received ST and 60 received T + P. Implementation costs (ST = $329, T + P = $617) were substantially higher than service delivery costs (ST = $18.7, T + P = $22.4) per participant. ST and T + P participants accrued 46.5 and 49.4 QALYs, respectively. The ICERs for T + P relative to ST were $4422 per QALY gained (95% confidence interval: $2484 to $9550) - slightly above the highly cost-effective threshold - and -$53.21 (95% confidence interval: -$105.8 to -$30.2) per unit change on the Patient Health Questionnaire.

CONCLUSION

Providing HAP within integrated depression services in Chitwan was cost-effective, if not highly cost-effective. Efforts to scale up integrated services in Nepal and similar contexts should consider including evidence-based psychological interventions as a part of cost-effective mental healthcare for depression.

A Meta-analytic Review: Psychological Treatment of Subthreshold Depression in Children and Adolescents

OBJECTIVE

Subthreshold depression has been found to be associated with considerable impairment and an increased risk of developing major depression. Although several randomized trials have examined the effects of psychological interventions for subthreshold depression in children and adolescents, no meta-analysis has integrated the results of these trials.

METHOD

We searched 4 bibliographic databases and included randomized trials comparing psychological interventions with control conditions in children and adolescents scoring above a cut-off of a depression questionnaire but not meeting diagnostic criteria for major depression (or persistent depressive disorder) according to a diagnostic interview. Effect sizes and incidence rates of major depression were pooled with random effects meta-analyses.

RESULTS

A total of 12 trials with 1,576 children and adolescents met inclusion criteria. The overall effect size indicating the difference between treatment and control at post-test was g = 0.38 (95% CI = 0.14-0.63), which corresponds to a number-needed-to-treat (NNT) of 8.4. Heterogeneity was moderate to high (I² = 61; 95% CI = 28-79), and there was significant risk of publication bias (p < .04). The 2 studies in children less than 12 years of age showed nonsignificant effects (g = 0.01; 95% CI = -1.16 to 1.18). We found no significant effect on the incidence of major depression at follow-up (relative risk = 0.52; 95% CI = 0.25-1.08), although this may be related to low statistical power.

CONCLUSION

Interventions for subthreshold depression may have positive acute effects in adolescents. There is currently insufficient evidence, however, that these interventions are effective in children less than 12 years of age, or that they prevent the onset of major depression at follow-up.

Effect of a lay counselor delivered integrated maternal mental health and early childhood development group-based intervention in Siaya County, Kenya: A quasi-experimental longitudinal study

BACKGROUND

Maternal mental health is linked to early childhood development; yet there is a gap in evidence-based interventions for low-resource settings. This study estimates the impact of 'Integrated Mothers and Babies Course and Early Childhood Development' (iMBC/ECD), a cognitive-behavioral, group-based intervention, on maternal depression and early childhood social-emotional development in Siaya County, Kenya.

METHODS

This quasi-experimental study enrolled 417 pregnant women and mothers of children under age 2 across two sub-counties in Siaya County. The intervention area had 193 women in 23 groups implementing iMBC/ECD and the control area had 224 women in 30 groups exposed to ECD only content. Mother/index child dyads were followed for two years. To estimate the causal treatment effect from the non-randomized design, we implemented the propensity score weighting method with inverse probability weights.

RESULTS

At baseline, 10.2% of participants endorsed moderate/severe depressive symptoms. At 14-months post-intervention, 7.4% endorsed moderate/severe depression. Overall, iMBC/ECD intervention did not have a significant impact on reducing maternal depression or improving children's social and emotional development. However, sub-group analyses revealed that iMBC/ECD was associated with lowered depressive symptoms among women with no/low education, four or more children and/or no experience of intimate partner violence in the past year. Women with high program attendance (more than half of 14 sessions) also experienced consistently fewer depressive symptoms compared to those with lower attendance.

LIMITATIONS

Non-randomized study, sub-group analyses are exploratory.

CONCLUSIONS

The iMBC/ECD program may have the potential to improve maternal mental health and early child development for more targeted vulnerable populations.

PW-led interventions show promising benefits in improving outcomes for CMDs, PND, PTS, harmful alcohol/substance use, and dementia carers in LMICs.

Psychological treatment of depression in institutional settings: A meta-analytic review

BACKGROUND

Many depressed patients are treated in institutional settings. The number of studies focusing on psychotherapies for depressed patients in institutional settingsis limited, and only a few up-to-date meta-analyses have integrated the results of these studies.

METHODS

We conducted a meta-analysis of 32 randomized trials with 37 comparisons between psychotherapy and control conditions, examining the effects of psychotherapy for adult patients in institutional settings with depressive disorders.

RESULTS

We found that psychotherapy had a significant, small to moderate effect on depressive symptoms (g=0.42; 95% CI: 0.29~0.56), with low to moderate heterogeneity (I²=33; 95% CI: 0~55). The effects remained small but significant after adjustment for publication bias (g=0.27; 95% CI: 0.12~0.42) and in the studies with low risk of bias (g=0.32; 95% CI: 0.11~0.52). The effects were largely retained at 9 to 15 months follow-up and still significant, again after adjustment for publication bias and in studies with low risk of bias. We found no significant difference across types of institutional settings, including psychiatric inpatient settings and nursing homes, although no studies with a low risk of bias were available in nursing homes.

LIMITATIONS

We included different types of institutional settings, although we did not find a significant difference between settings. The number of studies was small and risk of bias was high in a considerable number of trials.

CONCLUSIONS

This meta-analysis provides evidence for a small to moderate and sustained effect of psychotherapy in patients in institutional settings with depression.

Interpersonal Psychotherapy-Adolescent Skills Training With Youth From Asian American and Immigrant Families: Cultural Considerations and Intervention Process

Although research has identified effective evidence-based depression prevention interventions for diverse youth, little is known about how the intervention process unfolds with immigrant family youth. This study utilized a qualitative approach to explore cultural and clinical differences in the implementation of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST) in two schools, one serving youth from primarily immigrant, Asian American families and the second, youth from mostly nonimmigrant, non-Hispanic White families. A total of 131 IPT-AST sessions were audio recorded, transcribed, and coded for presence and patterns of cultural and clinical constructs. Results revealed that sessions with immigrant family youth were more likely to contain discussions of interpersonal problems characterized by estrangement, goals of spending time together with important others, mentions of emotion suppression and academic achievement expectations, conversations about acculturation, differences in value orientation, and discomfort with implementing new intervention skills. Dialogue from interventionist and youth exchanges is presented to illustrate how these themes emerged and were addressed by interventionists in a culturally responsive manner. The study highlights how IPT-AST with immigrant family and Asian American youth may unfold differently compared to youth from nonimmigrant families. Implications of findings for providers are discussed.

Lay-delivered talk therapies for adults affected by humanitarian crises in low- and middle-income countries

BACKGROUND

Published by the World Health Organization (WHO) and United Nations High Commissioner for Refugees (UNHCR) in 2015, the mental health Gap Action Programme Humanitarian Intervention Guide (mhGAP-HIG) recommends brief versions of structured psychological interventions for people experiencing symptoms of common mental disorders (CMDs). mhGAP-HIG acknowledges a growing body of evidence suggesting these interventions can be delivered by lay workers to people affected by humanitarian crises in low- and middle-income countries (LMICs). However, there has not yet been a systematic review and synthesis of this evidence. This paper reports the results of a systematic review of qualitative, quantitative, and mixed-methods studies assessing the implementation and/or effectiveness of talk therapies for CMDs when provided by lay workers in LMICs to adults who have survived or are currently living in humanitarian situations.

METHODS

Seven electronic databases were searched: MEDLINE, Embase, PsycINFO, PsycEXTRA, Global Health, Cochrane Library, and ClinicalTrials.gov . We also hand-searched the contents pages of three academic journals, reference lists of 30 systematic reviews, and online resource directories of two mental health networks. A preliminary list of included studies was circulated to topical experts for review, and all included studies were backward and forward searched. All titles, abstracts, and full-texts were independently double-screened. Quality appraisal and data extraction were carried out by a single reviewer and checked by a second reviewer, using standardised tools. Any disagreements were discussed and referred to a third reviewer as needed.

RESULTS

We identified 23 unique studies and carried out a narrative synthesis of patient and implementation outcome data. Every evaluation of the effectiveness of lay-delivered talk therapies for adults affected by humanitarian crises in LMICs showed some treatment effect for at least one CMD, and often multiple CMDs. Implementation research generally found these interventions to be acceptable, appropriate and feasible to implement, with good fidelity to manualised therapies.

CONCLUSION

Although results are promising, particularly for individually-delivered talk therapies based on cognitive behavioural therapy techniques, there is a high degree of heterogeneity in this literature. We make several recommendations on how to improve the quality and generalisability of research on this topic, to facilitate further evidence synthesis.

Care-as-usual control groups across different settings in randomized trials on psychotherapy for adult depression: a meta-analysis

BACKGROUND

Care-as-usual (CAU) is often used as a control condition in psychotherapy research, but it may vary considerably what that entails, ranging from no treatment, to routine treatment in primary care, general medical care, perinatal care, and specialized mental health care.

METHODS

We conducted a meta-analysis of trials comparing psychotherapy for depression to CAU, with a focus on the different categories of CAU and countries where the studies were conducted. We used an existing database of randomized trials on psychotherapy for depression that is updated every year.

RESULTS

A total of 140 studies with 15 419 patients were included. We found no significant differences in effects between categories of CAU (effect sizes ranging from g = 0.43 for CAU in primary care to g = 0.73 for no treatment), but heterogeneity was high in all CAU categories. After stratifying effects across specific countries (within CAU categories) we found that heterogeneity was considerably lower and there were several significant differences between countries. Overall, effects were larger in non-Western countries (g = 0.84 to 1.28) compared to those in Western countries (g = 0.52; p for difference = 0.002). Effects were smaller in studies with risk of bias (p = 0.01).

CONCLUSIONS

There are no significant differences between major categories of CAU when compared to psychotherapy conditions in randomized trials. However, effects of psychotherapy differ considerably across CAU conditions in specific countries. CAU therefore is a heterogeneous control condition in psychotherapy research.

Identifying challenges and recommendations for advancing global mental health implementation research: A key informant study of the National Institute of Mental Health Scale-Up Hubs

OBJECTIVE

This study explored perspectives of researchers working with the National Institute of Mental Health (NIMH) Scale-Up Hubs, consisting of research partnerships for scaling up mental health interventions in low- and middle-income countries (LMICs), to: 1) identify common barriers to conducting impactful research on the implementation of evidence-based mental health services; and 2) provide recommendations to overcome these implementation challenges.

METHODS

A sequential qualitative approach was employed. First, an open-ended survey was distributed to the 10 Scale-Up Hubs and NIMH program staff asking informants to identify challenges in conducting mental health implementation research in LMICs. Second, survey findings guided an in-person workshop to generate implementation recommendations to inform the field.

RESULTS

In total, 46 respondents completed surveys, and 101 researchers attended the workshop. The workshop produced implementation recommendations for low-resource settings: 1) identifying impact of research on policy and practice; 2) sustaining careers of early researchers in global mental health; 3) engaging policymakers and donors to value mental health research; 4) supporting the workforce for delivering evidence-based treatments for mental disorders; and 5) promoting sustainability of programs.

CONCLUSIONS

These findings can strengthen collaboration between researchers and key stakeholders, and highlight important targets for improving mental health implementation research in LMICs.
