This study evaluates a 17-session psychosocial intervention based on the Sports Education model for preadolescents from an ethnic minority community facing socio-educational exclusion. Using a pre-test/post-test design, the program significantly improved subjective well-being (increased positive affect, d = 0.80; decreased negative affect, d = 1.14) and reduced externalizing problems, including aggressiveness (d = 0.62) and behavioral difficulties (d = 0.79). Findings support the effectiveness of structured physical activity programs in fostering mental health and social adjustment among highly vulnerable youth, highlighting the value of evidence-based, holistic interventions in disadvantaged school settings.
