This research, based on a case study of vulnerable children in Korea, used a mixed methods transformative approach to explore strategies to support and help disadvantaged children. The methodological approach includes three phases: a mixed methods contextual analysis, a qualitative dominant analysis based on Sen's capability approach and critical communicative methodology to identify relevant value systems that support and impede resilience, and an action research approach to develop and implement the interventions. The adoption of mixed methods extends understandings of how to design, implement, and evaluate programs for vulnerable children.
