Abstract：
The present study examines the mediating effect of psychological factors in the structural relationships between social and physical environmental factors and the amount of physical activity among undergraduate students at Universiti Sains Malaysia. The sample consisted of 422 students with a mean age of 20.2 years (SD = 1.27). The majority of the students were female (69.7%) and Malay (81.3%). Standardized scales were used to measure the total amount of physical activity and all the study variables. The final SEM had a good fit to the data: CFI = 0.968, TLI = 0.948, SRMR = 0.036, RMSEA (90%CI) = 0.046 (0.025, 0.065), RMSEA p-value = 0.609 with 11 paths relationships. Family support had a significant effect on perceived benefits and perceived barriers. The effect of friend support on physical activity was significantly mediated by perceived benefits, self-efficacy, and psychological needs satisfaction. The effect of the availability of exercise facilities on physical activity was significantly mediated by perceived benefits and psychological needs satisfaction. Furthermore, psychological needs satisfaction mediated the effect of perceived benefits, perceived barriers, and self-efficacy on physical activity. The study findings illustrated that the application of the social-ecological model and psychological factors is important in order to understand and promote positive physical activity behaviour.
摘要：
本研究考察了心理因素在社会和物理环境因素之间的结构关系中的中介作用，以及马来西亚大学本科生的体育活动量。样本由422名学生组成，平均年龄为20.2岁（SD=1.27）。大多数学生是女性（69.7％）和马来人（81.3％）。标准化量表用于测量身体活动的总量和所有研究变量。最终的SEM对数据有很好的拟合:CFI=0.968,TLI=0.948,SRMR=0.036,RMSEA(90CI)=0.046(0.025,0.065),RMSEAp值=0.609，有11条路径关系。家庭支持对感知利益和感知障碍有显著影响。朋友支持对身体活动的影响是由感知到的好处显著介导的，自我效能感,心理需要满足。运动设施的可用性对身体活动的影响显着通过感知收益和心理需求满意度来调节。此外，心理需求满意度是感知利益的中介效应，感知障碍，和身体活动的自我效能感。研究结果表明，社会生态模型和心理因素的应用对于理解和促进积极的体育活动行为很重要。
