Adolescent girls report low physical activity levels and poor body image and self-esteem. This study evaluated the impact of a girls' health intervention on body image, self-esteem, and physical activity enjoyment. The intervention was grounded in self-determination theory, resulting in lessons designed to promote autonomy, competence, and relatedness. The two primary components of the intervention included opportunities for girls to learn about resistance training as well as ways to improve their psychosocial health (i.e., body image, self-esteem, and physical activity enjoyment). Girls ( = 590), in the intervention ( = 12.79, = 0.69) and control group ( = 12.92, = 0.73), completed pre and post measures. A repeated measures MANOVA was conducted to assess changes in body image, self-esteem, and physical activity enjoyment. The intervention resulted in a significant increase in body esteem-appearance, = 9.23, = 0.003, and body esteem-weight, = 4.77, = 0.029, and a greater, non-significant, increase in self-esteem (3.22%), and physical activity enjoyment (4.01%) compared to the control group. This highlighted the use of the intervention for significant improvements in appearance and weight-related body image. The results support implementing psychosocial lessons, as well as physical activity, in health programming for girls.
青少年女孩报告称身体活动水平较低，身体形象和自尊较差。本研究评估了一项针对女孩的健康干预措施对身体形象、自尊和身体活动乐趣的影响。该干预措施基于自我决定理论，产生了旨在促进自主性、能力和人际关系的课程。干预措施的两个主要组成部分包括让女孩有机会学习阻力训练以及改善其心理社会健康的方法（即身体形象、自尊和身体活动乐趣）。干预组（n = 590，M = 12.79，SD = 0.69）和对照组（n = 590，M = 12.92，SD = 0.73）的女孩完成了前后测量。进行了重复测量多元方差分析以评估身体形象、自尊和身体活动乐趣的变化。与对照组相比，干预措施导致身体自尊 - 外貌显著增加，F(1, 1176) = 9.23，p = 0.003，以及身体自尊 - 体重显著增加，F(1, 1176) = 4.77，p = 0.029，自尊有更大但不显著的增加（3.22%），身体活动乐趣有更大但不显著的增加（4.01%）。这突出了该干预措施在显著改善外貌和与体重相关的身体形象方面的作用。结果支持在针对女孩的健康规划中实施心理社会课程以及身体活动。
