Background: Developmentally-focused youth sport (DYS) programs combine sport and life skills to provide youth with opportunities for developing psychological and physical assets. Intervention dose may be associated with greater asset development. The purpose of this study was to evaluate the role of intervention dose on psychological and physical assets among 3rd-5th grade girls enrolled in the evaluation study of the Girls on the Run DYS program.

Methods: As part of a larger longitudinal quasi-experimental study, sub-analyses were conducted to evaluate the role of intervention dose among 1,027 participants categorized into one of three intervention exposure groups (never, one, ≥ two times). A 64-item self-report survey measured psychological (self-esteem, body image, and physical activity commitment) and physical (physical activity) assets at pre-intervention. Nested random effects ANOVA models were used to compare pre-intervention assets between groups.

Results: After adjustment for multiple comparisons, white girls who participated in the program ≥2 times had higher self-esteem (p=.027) when compared to never exposed white girls. There was no difference in self-esteem by intervention dose in non-white girls. Physical activity levels in non-white girls who had participated in the program once before were significantly higher than non-white girls who had never participated (p=.009). There was no significant difference in body size discrepancy by intervention dose.

Conclusions: Results suggest that the role of intervention dose on psychological and physical assets varies by developmental outcome. This study provides further evidence to support the effectiveness of Girls on the Run among 3rd-5th grade girls.
