PURPOSE
This study aimed to develop and validate the Girls' Disinclination for Physical Activity Scale (G-DAS)and implement the scale along with an objective measure of physical activity (PA) in a longitudinal sample of adolescent girls.
METHODS
Participants were non-Hispanic White girls who were assessed at ages 13 years (n=151) and 15 years (n=98). Girls completed the G-DAS and the Physical Activity Enjoyment Scale and wore an accelerometer for 7 days.
RESULTS
Results supported a five-factor solution for the GDAS;factors represented reasons for disliking PA including low perceived competence, lack of opportunities, high perceived exertion, concern about physical appearance,and threats to girls' gender identity. Data supported the reliability and validity of the G-DAS. Low perceived competence was the most common reason girls reported disliking PA and predicted a decreased likelihood of maintaining sufficient PA across ages 13 to 15 years.
CONCLUSION
Developing PA-related skills prior to adolescence may reduce declines in adolescent girls' PA.
目的
本研究旨在开发和验证女孩不喜欢体育活动量表（G-DAS），并在青少年女孩的纵向样本中使用该量表和客观的体力活动（PA）测量方法。
方法
参与者是非西班牙裔白人女孩，在 13 岁（n=151）和 15 岁（n=98）时进行评估。女孩们完成了 G-DAS 和体育活动享受量表，并佩戴加速度计 7 天。
结果
结果支持 G-DAS 的五因素解决方案；这些因素代表了不喜欢 PA 的原因，包括低感知能力、缺乏机会、高感知努力、对身体外观的担忧以及对女孩性别认同的威胁。数据支持 G-DAS 的可靠性和有效性。低感知能力是女孩报告不喜欢 PA 的最常见原因，并且预测了在 13 岁到 15 岁之间保持足够 PA 的可能性降低。
结论
在青春期之前发展与 PA 相关的技能可能会减少青少年女孩 PA 的下降。
