Evidence supporting the effectiveness of a developmental-focused youth sport (DYS) program designed exclusively for elementary school aged girls is mounting. The purpose of this study was to evaluate the impact of on the Girls on the Run program on psychological and physical assets among 3rd- to 5th-grade girls.
A longitudinal quasi-experimental study was conducted to evaluate intervention effects among 877 participants categorized into 1 of 3 groups (never, newly, and previously exposed). A 64-item self-report survey measured developmental assets at 3 time-points. Nested random effects ANOVA models were used to compare demographic factors and psychological and physical assets between exposure groups and to compare longitudinal differences in these assets.
After adjustment for multiple comparisons, previous program participants had significantly higher physical activity commitment (P = .006) and physical activity levels (P = .047) at preintervention than never exposed. From pre- to postintervention body image improved in newly exposed participants (P = .03). Physical activity increased from preintervention to follow-up among never and newly exposed participants (all P < .05).
Although we were unable to fully confirm the study hypotheses, the results of the current study provide new evidence to support future long-term studies examining the effectiveness of an innovative DYS program for 3rd- to 5th-grade girls.
支持专门为小学适龄女孩设计的以发展为重点的青少年体育（DYS）项目有效性的证据越来越多。本研究的目的是评估“女孩奔跑”项目对三至五年级女孩心理和身体资产的影响。
进行了一项纵向准实验研究，以评估877名参与者（分为三组：从未参与、新参与和曾参与）中的干预效果。一项64项自我报告调查在三个时间点测量发展资产。嵌套随机效应方差分析模型用于比较暴露组之间的人口统计学因素、心理和身体资产，并比较这些资产的纵向差异。
在对多重比较进行调整后，曾参与项目的参与者在干预前的身体活动承诺（P = .006）和身体活动水平（P = .047）显著高于从未参与的参与者。新参与项目的参与者从干预前到干预后身体形象得到改善（P = .03）。从未参与和新参与项目的参与者从干预前到随访期间身体活动增加（所有P < .05）。
尽管我们无法完全证实研究假设，但本研究结果为未来长期研究提供了新证据，以检验一项针对三至五年级女孩的创新DYS项目的有效性。
