The purpose of this study was to examine cognitive constructs from the theory of planned behavior (i.e., attitude, perceived behavioral control, and intention) as potential mediators of the relationship between selected social influence constructs (i.e., subjective norm, social support, and cohesion) and adherence to structured exercise classes. Sixty-two participants completed self-administered questionnaires during the fourth week (social influence constructs) and eighth week (cognitive constructs) of a 12-week exercise program. Exercise adherence was monitored during weeks 9 through 12 using perceived intensity and attendance. Pearson correlations indicated that social support correlated with perceived behavioral control, whereas cohesion correlated with attitude. Path analysis supported two distinct paths from social influence to exercise adherence: (a) social support-->perceived behavioral control-->intention-->exercise adherence, and (b) cohesion-->attitude-->intention-->exercise adherence. Discussion focuses on the theoretical importance of these findings, conceptual and measurement issues regarding subjective norm, and suggestions for future research.
本研究的目的是检验计划行为理论中的认知结构（即态度、感知行为控制和意图），作为所选社会影响结构（即主观规范、社会支持和凝聚力）与坚持参加结构化健身课程之间关系的潜在中介变量。62名参与者在一项为期12周的锻炼计划的第四周（社会影响结构）和第八周（认知结构）完成了自填式问卷。在第9周到第12周期间，使用感知强度和出勤情况来监测锻炼坚持情况。皮尔逊相关性分析表明，社会支持与感知行为控制相关，而凝聚力与态度相关。路径分析支持了从社会影响到锻炼坚持的两条不同路径：（a）社会支持→感知行为控制→意图→锻炼坚持，以及（b）凝聚力→态度→意图→锻炼坚持。讨论集中在这些发现的理论重要性、关于主观规范的概念和测量问题，以及对未来研究的建议。
