Abstract

The current study served as a practical and substantive guide to establishing longitudinal measurement invariance of psychosocial measures commonly used in adolescent physical activity (PA) research. Psychosocial data on an initial sample of 878 adolescents (ages 11 - 15) recruited through primary care providers were provided at baseline, 6, 12, and 24 months. The target measures included family support, peer support, decisional balance (pros, cons), self-efficacy, and behavioral strategies. Five of the six psychosocial measures exhibited strict longitudinal measurement invariance, with the 6th measure (self-efficacy) exhibiting strong longitudinal measurement invariance. These findings support the equivalence of these measures across time, and provide the foundation to substantively interpret group differences and associations involving these measures and PA.

摘要

本研究为在青少年身体活动(PA)研究中常用的心理社会测量方法建立纵向测量不变性提供了实用且实质性的指导。通过初级保健提供者招募的878名青少年(年龄11 - 15岁)的初始样本的心理社会数据在基线、6个月、12个月和24个月时提供。目标测量包括家庭支持、同伴支持、决策平衡(益处、弊端)、自我效能感和行为策略。六项心理社会测量中的五项表现出严格的纵向测量不变性,第六项测量(自我效能感)表现出强纵向测量不变性。这些发现支持了这些测量在不同时间的等效性,并为实质性解释涉及这些测量与身体活动的组间差异和关联提供了基础。
