Structural equation modeling (SEM) was used to examine the media-tion effect of refusal self-efficacy of internet use on the relation between depression and IA, whereas moderated mediation model was conducted by using the PROCESS macro for SPSS.The findings showed that refusal self-efficacy of internet use could partially medi-ate the effect of depression on IA. Actual and virtual social support moderated the indi-rect relationship between depression and IA via refusal self-efficacy of internet use. The results not only corresponded with TTI, and were also consistent with the buffering hy-pothesis.The study aimed to improve junior high school students’ ability to avoid IA when they were suffering from depression. The Moderated mediation model provided a com-prehensive understanding of how depression, actual social support, virtual social support and refusal self-efficacy of internet use work together to affect IA. Theoretical and practical implications were discussed.憂鬱情緒現實社會支持虛擬社會支持拒網自我效能網路成癮depressionactual social supportvirtual social supportrefusal self-efficacy of internet useinternet addiction學術論文
