Alternative Delivery Platforms for Expanding Evidence-based Mental Health Interventions for Youth in Sierra Leone: A Pilot Study

Advancing sustainable implementation of an evidence-based mental health intervention in Sierra Leone's schools: protocol for a hybrid type 3 implementation-effectiveness trial

BACKGROUND

Mental health disorders among youth contribute substantially to the global burden of disease, which is exacerbated in low- and middle-income countries (LMICs) due to large mental health treatment gaps. In Sierra Leone, a West African country with a long history of complex adversity, the mental health treatment gap is estimated at 98%. Implementing innovative mental health interventions that can be sustained at scale is a priority. The Youth Readiness Intervention (YRI) is an evidence-based mental health intervention for youth that can be delivered feasibly by lay health workers/nonspecialists. Using mobile-based technologies to assist implementation could improve the reach and sustainability of the YRI in Sierra Leone. This study aims to train teachers to deliver the YRI in Sierra Leone's secondary schools and test the feasibility, acceptability, cost, and fidelity to the YRI of a mobile-based supervision model compared with standard, in-person supervision.

METHODS

We will conduct a hybrid type 3 implementation-effectiveness cluster randomized trial to assess the feasibility, acceptability, costs and fidelity to the YRI implemented by teachers receiving mobile-based supervision vs. standard supervision. Enrolled schools (N = 50) will be randomized to YRI + mobile supervision (N = 20), YRI + standard supervision (N = 20) or waitlist control (N = 10). We will recruit and enroll four teachers per intervention-condition school (N = 160) and 1200 youth. We will collect data on implementation outcomes among teachers, principals and youth via a mixed methods approach at baseline and post-intervention. We will also collect quantitative data on youth mental health and functioning as secondary outcomes at baseline and post-intervention, as well as cost-effectiveness data at 12-month follow-up.

DISCUSSION

Study findings have the potential to expand the reach of mental health services among youth in low-resource settings via a teacher workforce. The use of mobile tools, if successful, could support further scale out and sustainment of the YRI to other regions of Sierra Leone and West Africa more broadly, which could help address the mental health treatment gap.

The adaptation of a youth mental health intervention to a peer-delivery model utilizing CBPR methods and the ADAPT-ITT framework in Sierra Leone

Low- and middle-income countries (LMICs) carry a significant proportion of the global burden of untreated mental health disorders. Peer-delivered programs offer LMICs with limited mental health professionals an opportunity to increase mental health service access. This study describes the process of adapting a lay-worker-delivered evidence-based youth mental health intervention to a peer-delivery model in Sierra Leone using participatory methods. We convened Youth Community Advisory Boards (YCABs) as partners to develop a peer-delivery model for an evidence-based intervention. In collaboration with YCABs, the Assessment, Decision, Administration, Production, Topical experts, Integration, Training, Testing (ADAPT-ITT) framework was applied to guide the adaptation. The ADAPT-ITT framework is an eight-step process to adapt evidence-based interventions. The ADAPT-ITT framework facilitated the adaptation of the Youth Readiness Intervention (YRI), an evidence-based mental health program intervention that has been delivered by adult lay-workers to the youth peer-delivery platform in Sierra Leone. The YCABs identified program modifications, including the incorporation of storytelling, refinement of metaphors, and alterations to make delivery more accessible to low-literacy youth with particular attention to gender. YCABs also provided recommendations on how to support youth facilitators in providing psychosocial support, emphasizing self-care and boundary setting to ensure high-quality intervention delivery and do-no-harm principles. Study findings suggest that the ADAPT-ITT framework can be feasibly applied to guide the intervention adaptation process in LMICs. The use of participatory methods generated modifications that reflected youth experiences, needs, and concerns as facilitators and participants. Next steps include refinement and pilot testing of the adapted intervention.

Global Mental Health: Where We Are and Where We Are Going

PURPOSE OF REVIEW

To summarize recent findings in global mental health along several domains including socioeconomic determinants, inequities, funding, and inclusion in global mental health research and practice.

RECENT FINDINGS

Mental illness continues to disproportionately impact vulnerable populations and treatment coverage continues to be low globally. Advances in integrating mental health care and adopting task-shifting are accompanied by implementation challenges. The mental health impact of recent global events such as the COVID-19 pandemic, geo-political events, and environmental change is likely to persist and require coordinated care approaches for those in need of psychosocial support. Inequities also exist in funding for global mental health and there has been gradual progress in terms of building local capacity for mental health care programs and research. Lastly, there is an increasing effort to include people with lived experiences of mental health in research and policy shaping efforts. The field of global mental health will likely continue to be informed by evidence and perspectives originating increasingly from low- and middle-income countries along with ongoing global events and centering of relevant stakeholders.

Exploring Naturalistic Diffusion of an Evidence-Based Mental Health Intervention across Peer Networks of Youth in Sierra Leone

BACKGROUND

Understanding the mechanisms by which evidence-based interventions (EBIs) for mental health are naturally diffused among youth in low-and middle-income countries-particularly those with histories of violence and civil unrest-can illuminate which intervention elements are most transferrable and inform scale-up decisions that support youth adjustment. This study explored the diffusion of an evidence-based mental health intervention-the Youth Readiness Intervention (YRI)-among peer networks of Sierra Leonean youth (aged 18-30) who participated in a trial of the intervention as integrated into youth entrepreneurship programs.

METHODS

Trained research assistants recruited index participants who had completed the YRI integrated within entrepreneurship training (N = 165) and control index participants (N = 165). Index participants nominated three of their closest peers. Nominated peers were recruited and enrolled in the current study (N = 289). A sub-sample of index participants and peers participated in dyadic interviews (N = 11) and focus group discussions (N = 16). Multivariate regression analysis compared YRI knowledge levels among YRI participants' peers relative to control participants' peers.

RESULTS

Qualitative findings supported the diffusion of several YRI skills and components across peer networks (i.e., progressive muscle relaxation and diaphragmatic breathing). Quantitative findings indicated that YRI knowledge was significantly higher for YRI participants' peers (β = 0.02, p < 0.00) compared to control participants' peers.

CONCLUSION

Findings suggest that diffusion of evidence-based intervention components can occur naturally among peers in post-conflict LMIC settings. Developing tools to promote the diffusion of the most transferrable EBI components across peer networks could help maximize the benefits of mental health interventions for youth adjustment and resilience in post-conflict settings.
