Addressing Youth-Focused Research Questions in a Community Context: Collecting and Integrating Mixed Methods Data at Multiple Ecological Levels with the PhotoStories Project.

Research seeking to understand and improve social conditions for marginalized youth would benefit from merging complex mixed methods research designs emphasizing multilevel data and participatory-social justice principles. We contribute to mixed methods research by introducing a multilevel, participatory-social justice mixed methods design that accomplishes this task and by illustrating its real-world application via PhotoStories, a multistage study aimed at understanding youths' community-based experiences and emotional well-being. During the project's three phases (preparation, training, and dissemination) we obtained and integrated quantitative and qualitative data at multiple ecological levels. Additionally, we examined youth perceptions about their participation, an important outcome given our participatory-social justice focus. We also provide lessons learned and recommendations for investigators seeking to use similar approaches for youth-focused research.
