目的:从两方面考察一项大学生身体活动促进研究的干预效果:1)干预是否改变了假想的调节变量;2)调节变量的改变是否与行为变化有关.方法:准实验设计.大学一年级学生被随机分为旨在促进身体活动的干预组和控制组.在学期初及干预后第8周,测量所有学生的身体活动结果和5个相关调节变量.结果:干预在女生的2个调节变量(自我效能创造时间锻炼方面,自我效能坚持不懈方面)上有显著性影响;而在男生的调节变量上无显著性影响.女生的3个调节变量变化得分(来自朋友的社会支持,来自家人的社会支持以及自我效能消极情感方面)是解释身体活动变化的回归分析中的显著性贡献因子,男生的身体活动变化中的2个显著性贡献因子分别是来自朋友的社会支持变化得分,自我效能坚持不懈方面的变化得分.结论:干预引起的女生的调节变量的显著改变与身体活动变化之间并没有显著性关联.干预研究的有效性没有得到验证.今后要在变量选择的多样性、测量过程的准确性、干预内容及相关理论方面进行改进.

This study evaluated the intervention effects of physical activity promotion of college students from two aspects： 1. Whether the intervention changed hypothesized mediators, 2. Whether the changes in mediators were associated with behavior change. Quasi-experimental design. First year college students were randomly divided into an intervention group targeting to promote physical activity and control group. At the beginning of semester and eighth week after intervention, physical activity outcome and five hypothesized mediators of both groups were assessed. The result showed that for female students ,the intervention bad significant effects on two of mediators including self-efficacy for making exercise time and self-efficacy for resisting relapse. For male students,there was no significant intervention on each mediator. For female students, significant contributors to regressions explaining physical activity change were social support from friends and family, and change in self-efficacy for negative effects. For male students, significant explanatory variables including change in social support from friends and change in self-efficacy for resisting relapse. It concluded that there was no significant correlation between significant change in mediators produced by intervention and physical activity outcome change of female students. The intervention effect was not supported. Further study should be done in improvement of variable choice ,measurement ,intervention and relevant theories.
