The present study investigated the relationship between internal locus of control and the perceived impact of Instagram fitspiration images on the self with media literacy as the mediating role in this relationship. This study also examined the importance of body mass index (BMI) as a moderating factor in the mediated model, where higher BMIs could weaken the relationship between internal locus of control and the perceived effect of fitspiration images mediated through media literacy. A sample of 321 Malaysian university students who were fitspiration viewers filled out a self-report questionnaire assessing internal locus of control, media literacy, perceived effect of fitspiration images on self, body satisfaction and BMI. The data analysis was performed using SPSS PROCESS macro. Results show that internal locus of control is negatively associated with the perceived impact of fitspiration images on self, mediated by media literacy. However, BMI moderates the mediated relationship such that the negative relationship between internal locus of control and the perceived effect of fitspiration images through media literacy does not exert an effect on those with high BMI. These results accentuate the value of incorporating a potential mediator and moderator into the direct relationship between internal locus of control and perceived effect of media ideals on self to provide an enhanced understanding of this process and offer practical insights about the protective role of media literacy and negative effects of high BMI.
本研究调查了内部控制点与对 Instagram 健身励志图片对自身影响的感知之间的关系，其中媒体素养作为中介变量在这种关系中发挥作用。本研究还探讨了体重指数（BMI）作为中介模型中调节因素的重要性，其中较高的 BMI 可能会削弱内部控制点与通过媒体素养中介的健身励志图片感知效果之间的关系。本研究的样本包括 321 名马来西亚大学生，他们是健身励志图片的观看者，填写了一份自我报告问卷，评估内部控制点、媒体素养、对健身励志图片对自身影响的感知、身体满意度和 BMI。数据分析使用 SPSS PROCESS 宏进行。结果表明，内部控制点与对健身励志图片对自身影响的感知呈负相关，这是由媒体素养介导的。然而，BMI 调节了中介关系，使得内部控制点与通过媒体素养感知健身励志图片效果之间的负相关关系对 BMI 较高的人没有影响。这些结果强调了在内部控制点和对自我的媒体理想感知的直接关系中纳入潜在的中介和调节因素的重要性，以提供对这一过程的更深入理解，并提供关于媒体素养的保护作用和高 BMI 的负面影响的实际见解。
