【摘要】 基于自我扩散理论，探索校园人际交往中大学生锻炼行为的形成机制。采用人际关系量表、体育锻炼等级量表、运动氛围量表和身体锻炼自我效能感量表，对1 308名大学生进行在线问卷调查。借助spss26.0软件包进行独立样本T检验、单因素方差分析、皮尔逊积差相关、Harman单因素共同方差偏差校验，以及Process宏程进行Bootstrap中介效应检验等。结果表明：人际关系与锻炼行为、运动氛围和锻炼自我效能感均呈显著正相关(P<0.01);人际关系显著正向预测运动氛围和锻炼自我效能感(P<0.01),运动氛围正向预测锻炼自我效能感(P<0.01),人际关系、运动氛围、锻炼自我效能感正向预测大学生锻炼行为(P<0.01);运动氛围和锻炼自我效能感在人际关系影响大学生锻炼行为间起到链式中介作用，中介效应数值和占比别为0.076(15.96%)。因此，人际关系可以通过运动氛围和锻炼自我效能感间接预测大学生体育锻炼行为。更多还原

【Abstract】 Based on the theory of self-diffusion theory, the formation mechanism of college students’ exercise behavior in campus interpersonal interaction was explored. The Interpersonal Relationship Scale, Physical Exercise Rating Scale, Exercise Atmosphere Scale and Physical Exercise Self-Efficacy Scale were used to conduct an online questionnaire survey on 1 308 college students. The independent sample t-test, one-way ANOVA, Pearson’s product variance correlation, Harman’s one-way common variance bias check, and Bootstrap mediation effect test were conducted with the help of spss2 6.0 software. The results showed that: interpersonal relationships are significantly and positively correlated with exercise behavior, exercise atmosphere, and exercise self-efficacy(P<0.01); interpersonal relationships significantly and positively predict exercise atmosphere and exercise self-efficacy(P<0.01); exercise atmosphere positively predicts exercise self-efficacy(P<0.01); interpersonal relationships, exercise atmosphere, and exercise self-efficacy positively predict college students’ exercise behaviors(P<0.01); exercise atmosphere and exercise self-efficacy play a chain mediating role between interpersonal relationships and college students’ exercise behaviors, with mediating effect values and percentages of 0.076(15.96%), respectively. Therefore, interpersonal relationships can indirectly predict college students’ physical activity behaviors through exercise atmosphere and exercise self-efficacy.更多还原
