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

Personalized stress optimization intervention to reduce adolescents' anxiety: A randomized controlled trial leveraging machine learning

Anxiety symptoms are among the most prevalent mental health disorders in adolescents, highlighting the need for scalable and accessible interventions. As anxiety often co-occurs with perceived stress during adolescence, stress interventions may offer a promising approach to reducing anxiety. Previous stress interventions have largely focused on the view that stress is harmful, aiming to manage and mitigate its negative effects. Stress optimization presents a novel intervention perspective, suggesting that stress can also lead to positive outcomes. However, it remains unclear whether stress optimization can effectively reduce anxiety symptoms in adolescents. We developed a single-session stress optimization intervention and investigated the conditions under which it was most effective. A large-scale randomized controlled trial was conducted (N = 1779, aged 12-18 years), with participants reporting their perceived stress, stress mindset, and anxiety over a two-month follow-up period. Machine learning is a promising approach for assessing personalized intervention effects. Conservative Bayesian causal forest analysis was employed to detect both treatment and heterogeneous intervention effects. The findings revealed that the intervention effectively reduced anxiety symptoms in the school context over a two-month follow-up (0.87 posterior probability). Furthermore, adolescents with higher anxiety and perceived stress at baseline experienced the most significant reductions in anxiety outcomes (standard deviations of -0.18 and -0.11 respectively). The single-session stress optimization intervention demonstrated potential for cost-effective scaling.

Effects of a self-affirmation intervention among Chinese adolescents during the COVID-19 pandemic: A large-scale randomized controlled trial

The COVID-19 pandemic, characterized by its highly contagious nature and devastating death toll, posed a dual threat to both physical and psychological well-being. As a potential intervention to alleviate the psychological impact, values-affirmation involves individuals engaging in the activity of writing about their core values. While its effectiveness in non-WEIRD (i.e. Western, Educated, Industrialized, Rich, Democratic) populations, notably among Chinese adults, has been confirmed, it remains largely unexplored whether the intervention can promote mental health in Chinese adolescents, especially in the context of the COVID-19 pandemic. The purpose of this study thus is to provide the first empirical evaluation of this intervention in promoting well-being and alleviating psychological distress among Chinese adolescents during the COVID-19 pandemic. A total of 2,234 students from 112 secondary schools in China were randomly assigned to an affirmation or control condition. The study found that self-affirmation intervention improved students' life satisfaction, mental health, and self-esteem, as well as buffered a decline of their purpose in life; however, no effects were found for clinical measures of depression, anxiety, and loneliness. The results suggest that self-affirmation interventions, while having limited effects on clinically relevant outcomes, can be an effective approach to boost well-being in adolescents during a major crisis, including in a more historically collectivist culture. Implications for self-affirmation theory and cultural psychology, as well as avenues for future research, are discussed.

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.

Results from a Pilot Randomized Controlled Trial of a Single-Session Growth-Mindset Intervention for Internalizing Symptoms in Autistic Youth

Autistic youth experience elevated rates of co-occurring internalizing symptoms. Interventions to treat internalizing symptoms in autistic youth are almost uniformly costly and time-intensive, blunting dissemination of intervention and highlighting the need for scalable solutions. One promising option is a relatively new class of evidence-based treatments, single-session interventions (SSIs), however, no study has examined SSIs for depression symptoms in autistic youth. Participants included 40 autistic adolescents ranging in age from 11 to 16 (Mage = 14.22, Nmale = 32). Eligible youth who agreed to participate were randomized to either the active intervention (Project Personality), or an active control designed to mimic supportive therapy. Participants and their caregiver completed questionnaires immediately before, after, and three months post intervention. All participants completed the intervention independently and largely reported enjoying it. The intervention was delivered with 100% fidelity. Findings demonstrated improvements in perceived primary control, malleability of personality, and social competence relative to the active control group immediately post-intervention. Further, results revealed improvements in self-reported depression symptoms and parent reported emotional regulation at 3-month follow up. This study was the first to assess a GM-SSI designed to treat depression symptoms in autistic adolescents. Results indicated improvements in perceived control immediately post-intervention and downstream improvements in depression. Nonetheless, we did not find improvements in symptoms of anxiety, suggesting that autistic adolescents may require modifications to the intervention to maximize benefit. Findings demonstrate the utility of GM-SSI for internalizing symptoms for autistic youth and hold considerable promise as a low-intensity and scalable intervention.

Academic Stress Interventions in High Schools: A Systematic Literature Review

The experience of academic stress is common during high school and can have significant negative consequences for students' educational achievement and wellbeing. High school students frequently report heightened levels of school-related distress, particularly as they approach high-stakes assessments. Programs designed to reduce or prevent academic stress are needed, and their delivery in school settings is ideal to improve treatment access. The current review aimed to examine the effectiveness of high school-based programs in reducing or preventing academic stress. A systematic search returned 31 eligible studies across 13 countries. Programs were categorised according to intervention type, format, and facilitator. Results showed that the methodological quality of most studies was poor, and many used an inactive control group. As predicted by theories of academic stress, the strongest evidence was for programs grounded in cognitive-behavioural therapy (CBT). There was evidence that both universal and targeted approaches can be beneficial. The unique implementation issues for these two formats are discussed. Most programs were delivered by psychologists and were generally effective, but almost all of these were CBT programs. A smaller proportion of programs delivered by teachers were effective. Therefore, future studies should evaluate the implementation success of programs to improve the rate of effective delivery by school staff. Overall, the field will benefit from more randomised controlled trials with comparisons to active control groups, larger sample sizes and longer-term follow-ups.

Community-based models of care for adolescent and adult depression, suicidal behavior, anxiety, trauma, and substance use in Africa: a scoping review

Background

Community-based care (CBC), where care is delivered outside of the traditional health facility setting, has been proposed to narrow the mental health (MH) and substance use (SU) treatment gap in Africa.

Objective

This scoping review aims to comprehensively summarize CBC models addressing adolescent and adult MH (depression, anxiety, trauma, suicidal behavior) and (non-tobacco) SU problems in Africa.

Methods

We searched PsycINFO, Embase, Scopus, CINAHL, and Medline Ovid. Studies and protocols were included if they reported on CBC intervention's effects on MH or SU symptoms/ diagnoses, acceptability, feasibility, or patient engagement in care, regardless of whether the intervention itself was designed specifically for MH or SU.

Results

Among 11,477 screened publications, 217 were eligible. Of the unique intervention studies (n = 206), CBC models were classified into the following approaches (non-mutually exclusive): psychotherapeutic (n = 144), social (n = 81), lifestyle/physical health (n = 55), economic (n = 26), and psychopharmacological (n = 2). While quantitative results suggest possible efficacy of CBC models, description of CBC location was often poor. Fewer interventions addressed suicidal behavior (n = 12), the needs of adolescents (n = 49), or used traditional healers or religious figures as providers (n = 3).

Conclusion

Many CBC models have been tested on MH and SU in Africa and should be critically appraised and meta-analyzed in subsequent reviews, where possible.

An app-based training for adolescents with problematic digital-media use and their parents (Res@t digital): protocol for a cluster-randomized clinical trial

Background

Digital media-use disorders (DMUD) in adolescents are a rising phenomenon associated with psychological distress, comorbid mental disorders, and high burden on affected families. Since the ICD-11 introduced criteria for gaming disorder, these can now be transferred to describe additional DMUD associated with social media platforms and streaming services. Most evidence for effective treatments comes from cognitive-behavioral therapy (CBT). However, interventions based on theoretical models for adolescents and their parents are widely missing, leading to a significant clinical gap.

Methods

Res@t digital (Resource-Strengthening Training for Adolescents with Problematic Digital-Media Use and their Parents) is the app-based translation of the first model-based digital intervention for adolescents with DMUD and their parents based on CBT. It comprises separate but content-related modules for adolescents (Res@t-A) and parents (Res@t-P), applying multimodal techniques. The effectiveness of Res@t will be evaluated within a multicenter cluster-randomized controlled evaluator-blinded pre-post follow-up trial with the waitlist control group (CG). In addition to the Res@t program in the intervention group, both groups will receive treatment as usual within primary child and adolescent psychiatric/psychotherapeutic healthcare. The primary outcome addresses DMUD symptom reduction after 10 weeks. Secondary outcomes are related to a reduction in psychological and family-related problems and an increase in parental self-efficacy. All outcomes will be assessed using standardized self-report measures. A total of 1,334 participating adolescent-parent dyads from a large clinical network throughout Germany are planned to be included in the primary analyses based on an intention-to-treat approach, applying linear mixed models.

Discussion

Assuming superiority of Res@t over the control condition, the intervention has the potential to provide evidence-based treatment for a significant number of help-seeking families, supporting local healthcare structures and resources. It is a promising program for practicable implementation and flexible use in different settings.

A roadmap to address stress in graduate students: How to develop and disseminate a student-led single-session evidence based intervention

Objective: This manuscript describes an evidence-based, student-led, single-session group intervention to support emotional wellbeing among graduate students. The present objective is to provide a roadmap for other universities. Participants: Key participants include clinical psychology graduate students (leader and workshop facilitators), faculty supervisor, representatives from receiving departments or schools, and institutional advocates. Methods: The two-hour workshop was based on four core transdiagnostic cognitive behavioral skills, including psychoeducation about emotions, mindful emotional awareness, cognitive flexibility, and behavior change. The workshop was designed and continues to be led by trained graduate students. Results: Key steps and lessons learned are presented for the exploration, preparation, implementation, and sustainment phases. Conclusions: This program has the potential to be flexibly replicated at other universities to assist with graduate student mental health. It provides unique supports for recipients and unique training opportunities for student facilitators.

Effectiveness of school-based psychological interventions for the treatment of depression, anxiety and post-traumatic stress disorder among adolescents in sub-Saharan Africa: A systematic review of randomized controlled trials

BACKGROUND

Mental disorders among adolescents represent a high burden and early onset. They compromise their physical health, survival, and future potential. On the other hand, young people have inadequate access to essential health services in sub-Saharan Africa. We aimed to review school-based psychological interventions, contents, delivery, and evidence of effectiveness designed to treat depression, anxiety, or posttraumatic stress symptoms among adolescents and young adults aged 10-24.

METHOD

We searched articles on the following databases: PubMed, Scopus, Embase, and Science Direct from 17/10/2022 to 30/12/2022. Furthermore, relevant studies were searched from advanced google scholar, google and identified reference lists. We used MeSH browser for key words: psychological interventions, depression, anxiety, posttraumatic stress disorder and lists of Sub-Saharan Africa countries. We combined words using standard Boolean operators (OR, AND). The quality of studies was evaluated using the Cochrane Collaboration's risk of bias tool and the results were presented as a narrative synthesis since the interventions were very heterogenous.

RESULTS

Fourteen randomized controlled trials were included for systematic review and more than half (57.14%) were from Kenya and Nigeria. Common school-based psychological interventions were cognitive behavioral therapy and Shamiri interventions (an intervention that focuses on youths to cultivate a growth mindset, practice gratitude and take the value). More than half (57.14%) of the interventions were delivered by non-specialists like teachers, lay providers and community health workers. Nearly one-fifth of the interventions were used individual modality. School-based psychological interventions provided by non-specialists also produced a greater reduction in adolescents' depressive, anxiety, and post-traumatic stress symptoms compared to the control groups.

CONCLUSION

Cognitive behavioral therapy and Shamiri interventions were the common treatment delivered in school settings. The range of interventions could be effectively delivered by non- professionals that promote task-shifting of psychological interventions from very scarce mental health specialists in these countries.

Sense of purpose interventions for depression and anxiety in youth: A scoping review and cross-cultural youth consultation

BACKGROUND/OBJECTIVES

To investigate the effectiveness, feasibility, and acceptability of sense of purpose (SOP) interventions in preventing or reducing anxiety or depression in youth aged 14-24 years.

METHODS

A systematic search was conducted of the academic (PubMed/MEDLINE, PsycINFO, EMBASE) and grey literature. We also consulted two SOP experts and an Australian and Indian youth advisory group with lived experience of anxiety and/or depression. Consultations focused on the feasibility and acceptability of reviewed interventions.

RESULTS

The search identified 25 studies reporting on 4408 participants from six countries (64.0 % of studies in the US). Multi-component interventions targeting several SOP components (i.e., value clarification, goal setting, gratitude enhancement) reported, on average, moderate reductions in depression and anxiety symptoms in youth. Interventions were generally more effective at reducing depression than anxiety symptoms. In terms of sub-populations or groups, there was some evidence for greater intervention effectiveness among youth with prior therapy experience, extraverted personalities, and those with already elevated anxiety/depression symptoms. Youth advisors and experts opined that group interventions were most acceptable to young people.

LIMITATIONS

This review was limited to a recent 10-year timeframe and publications in English, potentially excluding relevant studies published prior to 2011 or in other languages.

CONCLUSIONS

Fostering SOP can lead to better psychological wellbeing in youth. Potential harms resulting from interventions can occur without adequate consideration for a person's readiness for purpose discovery, environmental barriers, and familial and cultural settings. Further research in more diverse populations is required to determine who benefits and in what contexts.

Efficacy of school-based interventions for mental health problems in children and adolescents in low and middle-income countries: A systematic review and meta-analysis

Background

Implementation of interventions to treat child and adolescent mental health problems in schools could help fill the mental health care gap in low- and middle-income countries (LMICs). Most of the evidence available come from systematic reviews on mental health prevention and promotion, and there is less evidence on treatment strategies that can be effectively delivered in schools. The aim of this review was to identify what school-based interventions have been tested to treat children and adolescents in LMICs, and how effective they are.

Methods

We conducted a systematic review including seven electronic databases. The search was carried out in October 2022. We included randomised or non-randomised studies that evaluated school-based interventions for children or adolescents aged 6-18 years living in LMICs and who had, or were at risk of developing, one or more mental health problems.

Results

We found 39 studies with 43 different pairwise comparisons, treatment for attention-deficit and hyperactivity (ADHD), anxiety, depression, and posttraumatic stress disorder (PTSD), Conduct disorder (CD). Pooled SMD were statistically significant and showed that, overall, interventions were superior to comparators for PTSD (SMD = 0.61; 95% CI = 0.37-0.86), not statistically significant for anxiety (SMD = 0.11; 95% CI = -0.13 to 0.36), ADHD (SMD = 0.36; 95% CI = -0.15 to 0.87), and for depression (SMD = 0.80; 95% CI = -0.47 to 2.07). For CD the sample size was very small, so the results are imprecise.

Conclusion

A significant effect was found if we add up all interventions compared to control, suggesting that, overall, interventions delivered in the school environment are effective in reducing mental health problems among children and adolescents.

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.
