Bidirectional Associations across Time between Entitativity, Positive Affect, Generosity, and Religiousness in Adolescents Training with a Religiously Affiliated Charity Marathon Team

Numerous studies have established that participation in regular physical activity provides physical, cognitive, and affective benefits to adolescents, but fewer studies have examined how athletic involvement might affect character, social, or religious developmental markers of psychosocial functioning. The purpose of this study is to examine the bidirectional associations between entitativity (group closeness), positive affect, generosity, and religiousness across time among adolescents and emerging adults involved in charitable marathon training. We collected data from 396 adolescents and emerging adults who trained for half/full marathons with a religiously affiliated charity team. Participants completed measures at three occasions over 18 weeks (pre-training, mid-training, post-race). We conducted cross-lagged path analysis of latent factors to study concurrent and longitudinal effects of intrinsic religiousness, positive affectivity, and entitativity on interpersonal generosity and fundraising. Participants who reported higher levels of pre-training generosity were more likely to experience positive affect during training, which predicted higher levels of post-race generosity. Likewise, the internalization of religious ideas, reflected in increased intrinsic religiousness during training, was associated with higher post-race generosity. Overall, results support the potential of charitable sporting events to promote positive psychosocial developmental outcomes.
