To examine social cognitive factors associated with physical activity (PA) among preadolescent girls.
Social cognitive theory was used to examine PA in girls (N=90; 71% African American) participating in Girls on the Run. Multiple regressions explored factors associated with PA at posttesting and 3-month follow-up.
Significant increases in PA, social influences, and self-efficacy were found, which were sustained at 3-month follow-up. Self-efficacy and social influences had the strongest relations to PA at posttest; self-efficacy remained the strongest predictor of PA at 3-month follow-up.
Social support and self-efficacy are important targets of PA interventions in preadolescent girls.
研究青春期前女孩身体活动（PA）相关的社会认知因素。
运用社会认知理论对参与“女孩跑步”项目的女孩（N = 90；71%为非裔美国人）的身体活动进行研究。多元回归分析探讨了后测及3个月随访时与身体活动相关的因素。
身体活动、社会影响和自我效能显著增加，并在3个月随访时持续存在。后测时，自我效能和社会影响与身体活动的关系最为密切；在3个月随访时，自我效能仍然是身体活动最强的预测因素。
社会支持和自我效能是青春期前女孩身体活动干预的重要目标。
