Testing the Shamiri Intervention and Its Components With Kenyan Adolescents During the COVID-19 Pandemic: Outcomes of a Universal, 5-Arm Randomized Controlled Trial.

OBJECTIVE: Mental health problems are prevalent among African adolescents, but professional treatment capacity is limited. Shamiri, an efficient lay provider-delivered intervention, has significantly reduced depression and anxiety symptoms in previous randomized controlled trials (RCTs). This trial investigated effects of the full Shamiri intervention and its components (growth-only, gratitude-only, and values-only) against a study skills control. METHOD: In a 5-group RCT with adolescents from Kenyan high schools, anxiety, depression, and well-being were self-reported through 8-month follow-up. The RCT occurred immediately after an unanticipated government-mandated COVID-19 shutdown forced 3 years of schoolwork into 2 years, escalating academic pressures. RESULTS: Participants (N = 1,252; 48.72% female) were allocated to: growth (n = 249), gratitude (n = 237), values (n = 265), Shamiri (n = 250), and study skills (n = 251) conditions. Longitudinal multilevel models showed that, across all conditions, anxiety scores significantly improved at midpoint (B = -0.847), end point (B = -2.948), 1-month (B = -1.587), 3-month (B = -2.374), and 8-month (B = -1.917) follow-ups. Depression scores also improved significantly at midpoint (B = -0.796), end point (B = -3.126), 1-month (B = -2.382), 3-month (B = -2.521), and 8-month (B = -2.237) follow-ups. Well-being scores improved significantly at midpoint (B = 1.73), end point (B = 3.44), 1-month (B = 2.21), 3-month (B = 1.78), and 8-month (B = 1.59) follow-ups. Symptom reduction with Shamiri matched that of pre-COVID-19 trials, but symptom reduction with study skills far outpaced that of trials before the COVID-19-related school shutdown (31% greater anxiety reduction and 60% greater depression reduction). Thus, in contrast to previous RCTs, this COVID-19-era trial showed no significant differences between outcomes in any intervention and active control groups. CONCLUSION: Our RCT conducted during a post-COVID-19 period of heightened academic pressure produced unexpected results. Improvements in youth-reported anxiety and depression were consistent with previous trials for Shamiri, but markedly larger than in previous trials for study skills. Control interventions teaching life skills may produce mental health benefits when they convey skills of particular contextual relevance. PLAIN LANGUAGE SUMMARY: A large five-group randomized controlled trial involved comparing the Shamiri Intervention to its component interventions (growth mindset, gratitude, and values affirmation) and a study-skills control. In contrast to previous studies of Shamiri, similar effects were observed across all groups (p<.05). This trial was conducted right after an unanticipated government-mandated COVID shutdown forced three years of schoolwork into two. Benchmarking analyses against previous trials showed approximately equal effects of Shamiri over time, but a 31% greater anxiety reduction and 60% greater depression reduction for the study-skills condition; this highlights the potential of interventions teaching highly relevant life-skills for improving mental health.

Group-based psychoeducational workshop for parents in Kenya: findings from a pilot study.

Introduction: Low levels of mental health literacy amongst parents can have negative effects on youth mental wellbeing and help-seeking behaviors. Here, we explored the impact of a brief psychoeducational workshop on improving parent mental health literacy and family relationships in Kibera, a low-resource high-risk setting in Nairobi, Kenya. Methods: The workshop was designed to address this issue, and it was delivered by trained facilitators to small groups of parents (N = 72). Data was collected at baseline, post-workshop, two-week follow-up, and one-month follow-up. Results: Statistical and thematic analysis of the data revealed significant improvements in parent mental health literacy scores and family relationships, indicating the acceptability and effectiveness of this workshop. Discussion: The findings suggest that brief, group-based psychoeducational workshops can be effective in improving parent mental health literacy and family relationships, thereby addressing challenges faced by parents and youth in the Kenyan context. Future studies are needed to conclusively determine if such workshops can improve participants' own mental health or their perception of child behavior.

Costs and cost-effectiveness of Shamiri, a brief, layperson-delivered intervention for Kenyan adolescents: a randomized controlled trial.

BACKGROUND: Low- and middle-income countries (LMICs) have the highest socio-economic burden of mental health disorders, yet the fewest resources for treatment. Recently, many intervention strategies, including the use of brief, scalable interventions, have emerged as ways of reducing the mental health treatment gap in LMICs. But how do decision makers prioritize and optimize the allocation of limited resources? One approach is through the evaluation of delivery costs alongside intervention effectiveness of various types of interventions. Here, we evaluate the cost-effectiveness of Shamiri, a group- and school-based intervention for adolescent depression and anxiety that is delivered by lay providers and that teaches growth mindset, gratitude, and value affirmation. METHODS: We estimated the cost-effectiveness of Shamiri using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) guidelines for economic evaluations. Changes in depression and anxiety were estimated using the Patient Health Questionnaire (PHQ-8) and Generalized Anxiety Disorder questionnaire (GAD-7) at treatment termination and 7-month follow-up using two definitions of treatment benefit. Cost-effectiveness metrics included effectiveness-cost ratios and cost per number needed to treat. RESULTS: Base case cost assumptions estimated that delivering Shamiri cost $15.17 (in 2021 U.S. dollars) per student. A sensitivity analysis, which varied cost and clinical change definitions, estimated it cost between $48.28 and $172.72 to help 1 student in Shamiri, relative to the control, achieve reliable and clinically significant change in depression and anxiety by 7-month follow-up. CONCLUSIONS: Shamiri appears to be a low-cost intervention that can produce clinically meaningful reductions in depression and anxiety. Lay providers can deliver effective treatment for a fraction of the training time that is required to become a licensed mental health provider (10 days vs. multiple years), which is a strength from an economic perspective. Additionally, Shamiri produced reliable and clinically significant reductions in depression and anxiety after only four weekly sessions instead of the traditional 12-16 weekly sessions necessary for gold-standard cognitive behavioral therapy. The school setting, group format, and economic context of a LMIC influenced the cost per student; however, broader conclusions about the cost-effectiveness of Shamiri have yet to be determined due to limited economic evaluations of mental health programs in LMICs.

The network approach: A path to decolonize mental health care.

The violent colonial history of psychiatry in Africa prevents individuals from help-seeking. Because of this history, mental health care is now stigmatized, and clinical research, practice, and policy fail to capture the salient features of distress across African communities. If we are to transform mental health care for all, we must adopt decolonizing frameworks to ensure mental health research, practice, and policy are enacted in a manner that is ethical, democratic, critical, and serves the needs of local communities. Here, we present that the network approach to psychopathology as an invaluable tool in achieving this purpose. The network approach recognizes mental health disorders not as discrete entities, but rather as dynamic networks that are made of psychiatric symptoms (called nodes) and the relationships between these symptoms (called edges). This approach can pave a path to decolonizing mental health care by alleviating stigma, allowing context-based understanding of mental health and mental health problems, opening new avenues for (low-cost) mental health care and empowering local researchers to pioneer context-based knowledge production and treatment.

Centering decriminalization of suicide in low - and middle - income countries on effective suicide prevention strategies.

Globally, over 800,000 people die by suicide every year. For every one completed suicide, 20 more attempts have been made. As previous attempts are one of the strongest predictors of future suicide, help-seeking in moments of crisis, particularly after an attempt, may have important implications for suicide prevention. Unfortunately, the criminalization of suicide in several countries hinders help-seeking, increases the stigmatization of those who attempt suicide and obstructs the accurate tracking of suicides. Here, we highlight the negative effects of suicide criminalization and discuss evidence-based strategies for suicide prevention such as means restriction, improved mental health literacy and access to psychosocial support, and responsible media coverage of suicides.

Depression and anxiety symptoms amongst kenyan adolescents: Psychometric Properties, Prevalence Rates and Associations with Psychosocial Wellbeing and Sociodemographic factors.

This study assessed the psychometric properties of standard Western-derived instruments, the prevalence of depression and anxiety symptoms, and their associations with sociodemographic and wellbeing variables in a large sample of Kenyan adolescents. Self-report measures of depression (PHQ-8) and anxiety (GAD-7) symptoms, social support, gratitude, happiness, optimism, and perceived control were administered to 2,192 Kenyan youths (57.57% female) aged 12-19. Both the PHQ-8 (α = 0.78) and GAD-7 (α = 0.82) showed adequate internal consistency. EFA with a sub-sample (N = 1096) yielded a 1-factor structure for both PHQ-8 and GAD-7, a subsequent CFA conducted on the basis of a 1-factor model on another sub-sample (N = 1096) yielded good and moderate goodness of fit, respectively, for the PHQ-8 (χ2 = 76.73; p < 0.001; RMSEA = 0.05; CFI = 0.96; TLI = 0.95) and the GAD-7 (χ2 = 88.19; p < 0.001; RMSEA = 0.07; CFI = 0.97; TLI = 0.95). Some 28.06% and 30.38% of participants met the clinical cut-off for depressive and anxiety symptoms, respectively. Social support, gratitude, happiness, and perceived control were negatively associated with both depression and anxiety symptoms. Older adolescents reported higher symptoms while adolescents with more siblings reported lower symptoms. The western-derived PHQ and GAD met conventional psychometric standards with adolescents in Kenya; depression and anxiety symptoms showed relatively high prevalence and significant associations with important psychosocial and sociodemographic factors.

Long-term health outcomes of adolescent character strength interventions: 3- to 4-year outcomes of three randomized controlled trials of the Shamiri program.

BACKGROUND: Adolescents in low- and middle-income countries in need of mental health care often do not receive it due to stigma, cost, and lack of mental health professionals. Culturally appropriate, brief, and low-cost interventions delivered by lay-providers can help overcome these barriers and appear effective at reducing symptoms of depression and anxiety until several months post-intervention. However, little is known about whether these interventions may have long-term effects on health, mental health, social, or academic outcomes. METHODS: Three previous randomized controlled trials of the Shamiri intervention, a 4-week, group-delivered, lay-provider-led intervention, have been conducted in Kenyan high schools. Shamiri teaches positively focused intervention elements (i.e., growth mindset and strategies for growth, gratitude, and value affirmation) to target symptoms of depression and anxiety and to improve academic performance and social relationships, by fostering character strengths. In this long-term follow-up study, we will test whether these mental health, academic, social, and character-strength outcomes, along with related health outcomes (e.g., sleep quality, heart-rate variability and activity level measured via wearables, HIV risk behaviors, alcohol and substance use), differ between the intervention and control group at 3-4-year follow-up. For primary analyses (Nanticipated = 432), youths who participated in the three previous trials will be contacted again to assess whether outcomes at 3-4-year-follow-up differ for those in the Shamiri Intervention group compared to those in the study-skills active control group. Multi-level models will be used to model trajectories over time of primary outcomes and secondary outcomes that were collected in previous trials. For outcomes only collected at 3-4-year follow-up, tests of location difference (e.g., t-tests) will be used to assess group differences in metric outcomes and difference tests (e.g., odds ratios) will be used to assess differences in categorical outcomes. Finally, standardized effect sizes will be used to compare groups on all measures. DISCUSSION: This follow-up study of participants from three randomized controlled trials of the Shamiri intervention will provide evidence bearing on the long-term and health and mental health effects of brief, lay-provider-delivered character strength interventions for youth in low- and middle-income countries.

Single-session interventions for adolescent anxiety and depression symptoms in Kenya: A cluster-randomized controlled trial.

OBJECTIVE: Expanding mental healthcare for adolescents in low-income regions is a global health priority. Group interventions delivered by lay-providers may expand treatment options. Brief, positively-focused interventions conveying core concepts of adaptive functioning may help reduce adolescent symptoms of mental illness. In this trial, we tested three such interventions (growth mindset, gratitude, and value affirmation) as separate single-session interventions. METHOD: Consenting adolescents (N = 895; Mage = 16.00) from two secondary schools in Kenya were randomized by classroom (24 classrooms; Mclass = 37.29 students) into single-session interventions: growth (N = 240), gratitude (N = 221), values (N = 244), or an active study-skills control (N = 190). Mixed-effects models controlling for age and gender were used to estimate individual-level intervention effects on anxiety and depression symptoms. RESULTS: Within the universal sample, the values intervention produced greater reductions in anxiety symptoms than the study-skills control (p < .05; d = 0.31 [0.13-0.50]). Within the clinical sub-sample (N = 299), the values (p < .01; d = 0.49 [0.09-0.89]) and growth interventions (p < .05; d = 0.39 [0.01-0.76]) produced greater reductions in anxiety symptoms. There were no significant effects on depression. CONCLUSIONS: The values intervention reduced anxiety for the full sample, as did the growth mindset and values interventions for symptomatic youths. Future efforts should examine durability of these effects over time.

Designing Culturally and Contextually Sensitive Protocols for Suicide Risk in Global Mental Health: Lessons From Research With Adolescents in Kenya.

In cross-cultural psychological treatment research, investigators must ensure that protocols for addressing risk are culturally tailored and feasible, while also protecting against harm. Guidelines including the Belmont Report1 and the Declaration of Helsinki2 emphasize respecting participants' autonomy and right to equitable treatment, minimizing harm and maximizing benefit, while considering unique circumstances, local laws and regulations, and cultures. They highlight the importance of supervision from qualified health professionals,2 and special protections for children.1 Suicide risk poses distinctive challenges for cross-cultural research; actions that protect participants in one cultural context may harm participants in another. For example, because suicide attempts are illegal in many countries (eg, Kenya, Gambia, Nigeria), involving law enforcement, or others who may report to them, can generate penalties and incriminate those at risk. Upholding the Belmont and Helsinki principles can therefore require adapting strategies for different cultural contexts. This Commentary outlines strategies for applying principles of ethical risk management3,4 that prioritize sensitivity to context. We focus on addressing participant suicide risk during clinical research in low-resource and high-stigma settings, presenting the example of risk among adolescents in Kenya.5,6.

Testing the effects of the Shamiri Intervention and its components on anxiety, depression, wellbeing, and academic functioning in Kenyan adolescents: study protocol for a five-arm randomized controlled trial.

BACKGROUND: Treatments for youth mental disorders are a public health priority, especially in sub-Saharan Africa (SSA), where treatment options remain limited due to high cost, elevated stigma, and lack of trained mental health professionals. Brief, accessible, and non-stigmatizing community-based interventions delivered by lay providers may help address treatment needs in SSA. One such intervention, the Shamiri Intervention, consisting of three elements (growth mindset, gratitude, and value affirmation) has been tested in randomized controlled trials with school-going Kenyan adolescents. This three-element Shamiri Intervention has been shown to significantly reduce depression and anxiety symptoms and improve social support and academic performance relative to a control group. In this trial, we aim to investigate the effects of each element of the Shamiri Intervention. METHODS: In this five-arm randomized controlled trial, we will test each of the intervention components (growth mindset, gratitude, and value affirmation) against the full Shamiri Intervention and against a study skills control intervention. Students (Nplanned = 1288) at participating secondary schools who are interested in participating in this universal intervention will be randomized in equal numbers into the five groups. The students will meet in groups of 8-15 students led by local high school graduate lay providers. These lay providers will receive a brief training, plus expert supervision once a week throughout the intervention delivery. Multi-level models will be used to compare trajectories over time of the primary outcomes (depressive symptoms, anxiety symptoms, academic performance, and wellness) and secondary outcomes in each intervention group to the control group. Multi-level models will also be used to compare trajectories over time of the primary outcomes (depressive symptoms, anxiety symptoms, academic performance, and wellness) and secondary outcomes of participants in the single-element interventions compared to the full Shamiri Intervention. Finally, effect sizes (calculated as mean gain scores) will be used to compare all groups on all measures. DISCUSSION: This trial will shed light on the mechanisms and outcomes targeted by each individual intervention, helping prioritize which mental health interventions are most important to disseminate.

Effect of Shamiri Layperson-Provided Intervention vs Study Skills Control Intervention for Depression and Anxiety Symptoms in Adolescents in Kenya: A Randomized Clinical Trial.

Importance: Low-cost interventions for adolescent depression and anxiety are needed in low-resource countries such as those in Sub-Saharan Africa. Objective: To assess whether Shamiri, a 4-week layperson-delivered group intervention that teaches growth mindset, gratitude, and value affirmation, can alleviate depression and anxiety symptoms in symptomatic Kenyan adolescents. Design, Setting, and Participants: This school-based randomized clinical trial included outcomes assessed at baseline, posttreatment, and 2-week and 7-month follow-up from 4 secondary schools in Nairobi and Kiambu County, Kenya. Adolescents aged 13 to 18 years with elevated symptoms on standardized depression or anxiety measures were eligible. Intent-to-treat analyses were used to analyze effects. Recruitment took place in June 2019; follow-up data were collected in August 2019 and February 2020. Intervention: Adolescents were randomized to the Shamiri intervention or to a study skills control. All adolescents in both conditions met in groups (mean group size, 9) for 60 minutes per week for 4 weeks. Main Outcomes and Measures: Primary outcomes were depression (Patient Health Questionnaire-8 item) and anxiety (Generalized Anxiety Disorder-7 item) symptoms. Analyses of imputed data were hypothesized to reveal significant reductions in depression and anxiety symptoms for adolescents assigned to Shamiri compared with those in the study skills group. Results: Of 413 adolescents, 205 (49.6%) were randomized to Shamiri and 208 (50.4%) to study skills. The mean (SD) age was 15.5 (1.2) years, and 268 (65.21%) were female. A total of 307 youths completed the 4-week intervention. Both Shamiri and study skills were rated highly useful (4.8/5.0) and reduced symptoms of depression and anxiety, but analyses with imputed data revealed that youths receiving Shamiri showed greater reductions in depressive symptoms at posttreatment (Cohen d = 0.35 [95% CI, 0.09-0.60]), 2-week follow-up (Cohen d = 0.28 [95% CI, 0.04-0.54]), and 7-month follow-up (Cohen d = 0.45 [95% CI, 0.19-0.71]) and greater reductions in anxiety symptoms at posttreatment (Cohen d = 0.37 [95% CI, 0.11-0.63]), 2-week follow-up (Cohen d = 0.26 [95% CI, -0.01 to 0.53]), and 7-month follow-up (Cohen d = 0.44 [95% CI, 0.18-0.71]). Conclusions and Relevance: Both the Shamiri intervention and a study skills control group reduced depression and anxiety symptoms; the low-cost Shamiri intervention had a greater effect, with effects lasting at least 7 months. If attrition is reduced and the clinical significance of outcome differences is established, this kind of intervention may prove useful in other global settings where there are limited resources, mental illness stigma, or a shortage of professionals and limited access to mental health care.

Conducting global mental health research: lessons learned from Kenya.

Mental health disorders are prevalent among youth and adolescents in low- and middle-income countries, and access to evidence-based treatments is poor. Although there is a great need for high-quality research to serve young people in low- and middle-income countries, there is limited guidance available for researchers who wish to conduct such work. Here, we describe our process of conducting school-based youth mental health work in Kenya over the last several years. We focus on five key lessons we learned that could guide future global mental health work with youth: (a) reducing stigma with strengths-focused interventions, (b) expanding access by working in schools, (c) generating buy-in from local stakeholders, (d) adapting the intervention via multicultural collaboration, and (e) applying insights from low- and middle-income countries to serve young people in high-income countries. We conclude by discussing how these lessons, and those shared by other teams, can be applied to help reduce the treatment gap for young people around the world.

The Shamiri group intervention for adolescent anxiety and depression: study protocol for a randomized controlled trial of a lay-provider-delivered, school-based intervention in Kenya.

BACKGROUND: Developing low-cost, socio-culturally appropriate, and scalable interventions for youth depression and anxiety symptoms in low-income regions such as countries in sub-Saharan Africa is a global mental health priority. We developed and intend to evaluate one such intervention for adolescent depression and anxiety in Kenya. The intervention, named Shamiri (a Swahili word for "thrive"), draws upon evidence-based components of brief interventions that involve nonclinical principles rather than treatment of psychopathology (e.g., growth mindset, gratitude, and virtues). METHODS: Four hundred twenty Kenyan adolescents (ages 13-18) with clinically elevated depression and/or anxiety symptoms will be randomized to either the 4-week Shamiri group intervention or a group study-skills control intervention of equal duration and dosage. Participating adolescents will meet in groups of 8-15, led by a high-school graduate trained to deliver Shamiri as a lay-provider. Adolescents will self-report primary outcome measures (depression-measured by the PHQ-8, and anxiety symptoms-measured by the GAD-7) and secondary outcome measures (perceived social support, perceived academic control, self-reported optimism and happiness, loneliness, and academic grades) at the 2-week intervention midpoint, 4-week post-intervention endpoint, and 2-week post-intervention follow-up. We predict that adolescents in the Shamiri group, when compared to the study-skills control group, will show greater improvements in primary outcomes and secondary outcomes. DISCUSSION: Results may suggest that a brief, lay-provider delivered, school-based intervention may reduce depression and anxiety symptoms, improving academic outcomes and other psychosocial outcomes in adolescents with clinically-elevated symptoms in sub-Saharan Africa.

Single-session digital intervention for adolescent depression, anxiety, and well-being: Outcomes of a randomized controlled trial with Kenyan adolescents.

BACKGROUND: Adolescent depression and anxiety symptoms are prevalent in sub-Saharan African countries, yet treatment options are scarce, and stigma limits help-seeking. Brief, computerized single-session interventions (SSIs) that contain empirically supported stigma-reducing elements may help expand access to treatment. We developed and evaluated such an intervention for Kenyan adolescents. METHOD: High school students (N = 103, age 13-18) were randomized to a digital SSI Shamiri-Digital (Shamiri means "thrive" in Kiswahili) or a study-skills control intervention. Shamiri-Digital consisted of reading and writing activities about 3 concepts: growth mindset, gratitude, and value affirmation. Both Shamiri-Digital and the study-skills control condition were delivered electronically in schools. RESULTS: Compared to the control, Shamiri-Digital produced a greater reduction in adolescent depressive symptoms in both the full sample (p = .028, d = 0.50) and a subsample of youths with moderate to severe depression symptoms (p = .010, d = 0.83) from baseline to 2-week follow-up. The effects exceed the mean effects reported in meta-analyses of full-length, face-to-face psychotherapy for youth depression. There were no significant effects on anxiety symptoms, well-being, or happiness. CONCLUSION: This is the first report that a brief, computerized SSI may reduce depressive symptoms in adolescents in sub-Saharan Africa. Replication trials with extended follow-ups will help gauge the strength and durability of these effects. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
