This article describes a study of a soccer and life skills programme for youth in South Africa: Buffalo City Soccer School (BCSS). The study aimed to provide insight into the programme’s mechanisms, and evaluate participants’ perceptions of the programme’s impact. Individual semi-structured interviews were conducted with 10 male BCSS participants. Interview data were analysed for thematic content, and the theoretical perspectives of Witt and Crompton ((1997) The protective factors framework: A key to programming for benefits and evaluating for results. Journal of Park and Recreation Administration 15: 1–18), Gambone and Arbreton ((1997) Safe Havens: The Contributions of Youth Organizations to Healthy Adolescent Development. Philadelphia, PA: Public/Private Ventures) and Pawson ((2006) Evidence-Based Policy: A Realist Perspective. London: SAGE) were used to interpret these themes. These perspectives highlighted key processes and mechanisms within the BCSS programme that have led to positive personal impacts: a sense of family and a sense of safety and belonging. Bandura’s ((1986) Social Foundations of Thought and Action: A Social Cognitive Theory. Englewood Cliffs, NJ: Prentice Hall) concepts of perceived self-efficacy and agency in adolescent development (Bandura A (2006) Adolescent development from an agentic perspective. In: Pajares F and Urdan T (eds) Self-Efficacy Beliefs of Adolescents. Greenwich, CT: Information Age Publishing, pp. 1–43) help make sense of these personal impacts. This study contributes to the identification of the mechanisms through which sport can provide a context for the development of youth.
