This study investigated the corresponding change between psycho-social predictors and physical activity (PA) behavior and if these relationships were dependent on the stages of change from the Transtheoretical Model in Minority American adolescents. We conducted a longitudinal field study with N = 357 students aged 13-18 years (M = 14.24 years, SD = 0.88); predominantly Filipino (61.2%) using a test-retest design assessing psycho-social PA predictors (enjoyment, self-efficacy, family support, friends' support, knowledge, stage of change) and moderate-to-vigorous physical activity (MVPA) at two time points over six months. Hierarchical regression results indicated that a positive change of enjoyment, knowledge about PA and family support predicted a change of MVPA, independently of stage. The time-varying covariation showed the importance of the current stage of change for enjoyment, self-efficacy and support of friends for a change of MVPA. Overall, our findings suggest that an individual's current stage of change should be considered to determine individually appropriate starting points and goals for designing interventions to promote PA among Minority American adolescents.
本研究调查了少数族裔美国青少年在跨理论模型改变阶段中，心理社会预测因素与身体活动（PA）行为之间的相应变化，以及这些关系是否取决于改变阶段。我们对 357 名 13-18 岁（M=14.24 岁，SD=0.88）的学生进行了一项纵向现场研究，主要是菲律宾裔（61.2%），采用测试-重测设计评估心理社会 PA 预测因素（享受、自我效能、家庭支持、朋友支持、知识、改变阶段）和六个月内两次的中等至剧烈体力活动（MVPA）。层次回归结果表明，享受、PA 知识和家庭支持的积极变化独立于阶段预测 MVPA 的变化。时变协方差表明，对于享受、自我效能和朋友支持的当前变化阶段对于 MVPA 的变化很重要。总的来说，我们的发现表明，应该考虑个体当前的改变阶段，以确定设计干预措施以促进少数族裔美国青少年进行 PA 的个别适当起点和目标。
