Abstract
BACKGROUND: Mental health problems disproportionately affect young people in developing countries. However, there is limited research on help-seeking behaviours and the social support systems that improve mental wellbeing among vulnerable youth populations. OBJECTIVE: This mixed-methods study aimed to examine the relationship between social support reciprocity and mental health among young informal construction workers in Nigeria, a population at high-risk for occupational and socioeconomic stressors. METHODS: A cross-sectional survey was administered to 686 informal workers to measure reciprocity, mental health-related quality of life, and covariates. In-depth interviews with 32 participants provided qualitative context. RESULTS: Quantitative analyses showed 25% of participants reported poor mental health. Reciprocity positively predicted mental health after controlling for covariates. Qualitative findings revealed reciprocity occurs directly between individuals as well as indirectly through trade unions and religious groups. Indirect exchanges through groups helped address limitations of direct support due to limited resources. CONCLUSIONS: This study fills important gaps in understanding how social relationships impact mental health in developing country contexts. Findings emphasize the role of collective action and community-based support systems in promoting mental wellbeing among vulnerable populations. Insights can inform culturally relevant, systems-level mental health interventions.
