目的 评估社会支持和计划行为理论 (TPB) 在解释青春期女孩身体活动方面的构建。方法 1797 名八年级女生完成了一项调查，衡量社会供给、家庭支持、TPB 结构、中度至剧烈体育活动 (MVPA) 和团队运动参与 (TSI)。结果 结构方程模型 (SEM) 表明 TPB 结构和社会规定对意图具有统计显着的直接影响；社会供给、家庭支持和 MVPA 意愿；以及对 TSI 的社会供给和家庭支持。结论 在此样本中，社会变量在解释 TSI 方面比在解释 MVPA 方面发挥更大的作用。
OBJECTIVE To evaluate social support and theory of planned behavior (TPB) constructs in explaining physical activity in adolescent girls. METHODS One thousand seven hundred ninety-seven 8th-grade girls completed a survey measuring social provisions, family support, TPB constructs, moderate-to-vigorous physical activity (MVPA), and team sport involvement (TSI). RESULTS Structural equation modeling (SEM) indicated statistically significant direct effects from TPB constructs and social provisions to intention; social provisions, family support, and intention to MVPA; and social provisions and family support to TSI. CONCLUSIONS Social variables play a greater role in explaining TSI than in explaining MVPA in this sample.
