Developing & Testing the Feasibility of a Sports-based Mental Health Promotion Intervention for Adolescents in Nepal: a Community Engagement Approach

Depression and anxiety are the leading contributors to the global burden of disease among young people, accounting for over a third (34.8%) of years lived with disability, and contributing significantly to excess mortality through suicide. Adolescence is the peak age of onset for most mental health conditions, with approximately 50% of lifetime mental health conditions having their onset by mid-adolescence. Adolescent depression in turn predicts several adverse life trajectories, such as failure to complete secondary school, unemployment and unplanned pregnancy or parenthood. Early intervention programmes for adolescents can promote mental health, prevent mental disorders, and prevent risky behaviours and other unhealthy lifestyle choices. These programmes have the potential to make positive contributions to adolescents' health, and to their health in later life. One such intervention is mental health promotion, which focuses on improving positive behaviors and characteristics that protect mental health. Mental health promotion is a strategy to improve the positive behaviors and characteristics that protect mental health

A pilot trial will be conducted to assess the feasibility, acceptability and utility of the intervention and trial design; safety and delivery of the intervention in the community settings; and to identify issues around training, supervision and outcomes measures. A household survey will be conducted at baseline and end line data collection points. After a baseline data collection, the implemention of the intervention will be conducted for around 10 months' period, and then collect the follow-up (end line) data with adolescents.

A parallel-group, two-arm, superiority, cluster-randomised controlled trial with 1:1 allocation to intervention and control arms will be done. In total there will be four clusters (2 control and 2 intervention clusters). The unit of randomization will be a geographic village cluster of ~1000 people (approx 160 adolescents in each cluster). Clusters will be separated geographically which will mitigate risk of contamination in the control arm. A researcher will visit each household in the clusters and ask if there are any adolescents living in the household. Where appropriate consent is obtained, the researcher will then interview eligible adolescents using a smartphone or tablet pre-programmed with the survey. The main trial analysis will be a cross-sectional comparison of data from the endline survey, adjusted for baseline differences. Intervention activities will be open to all adolescents aged 12-19 living in the community to participate. The acceptability of the intervention, randomisation, tools, uptake, utility of the intervention, facilitators' fidelity to the manual, mental health outcome trends, and cost of design and delivery of the intervention will be assessed. The intervention process data will be also collected. This will include FGDs and interviews with adolescents and their parents, facilitators and trainers to explore feasibility and acceptability of the intervention and study procedures.
