Internet addiction is a growingly prevalent behavioral addiction that causes numerous psychosocial problems. Investigating the causes and consequences of Internet addiction is fundamental to comprehend and prevent it. Therefore, the current study provided protective and promotive factors for undesired effects of social exclusion on Internet addiction. The study examined a moderated mediation model to test whether mindfulness moderated the mediating role of self-forgiveness in the association between social exclusion and Internet addiction among young adults. The participants of the present study included 358 undergraduate students attending a state university in Turkey. They ranged in age from 20 to 28 years (M = 21.89, SD = 1.95). The participants comprised 206 (57.5%) female and 152 (42.5%) male college young adults. Overall, the study findings indicated that self-forgiveness mediated the relationship between social exclusion and Internet addiction, and mindfulness moderated the mediating role of self-forgiveness in this association. Contending with negative outcomes of social exclusion and Internet addiction, and mitigating and buffering roles of self-forgiveness and mindfulness provide important implications to design prevention and intervention services for reducing Internet-related addictive behaviors.

网络成瘾是一种日益普遍的行为成瘾，会导致许多心理社会问题。调查网络成瘾的原因和后果是理解和预防它的基础。因此，目前的研究为社会排斥对网络成瘾的不良影响提供了保护和促进因素。该研究检查了一个有调节的中介模型，以测试正念是否调节了自我宽恕在年轻人社会排斥和网络成瘾之间的关联中的中介作用。本研究的参与者包括就读于土耳其一所国立大学的 358 名本科生。他们的年龄从 20 岁到 28 岁不等（M  = 21.89，SD = 1.95)。参与者包括 206 名 (57.5%) 女性和 152 名 (42.5%) 男性大学生。总体而言，研究结果表明，自我宽恕在社会排斥和网络成瘾之间起中介作用，而正念在这种关联中调节了自我宽恕的中介作用。应对社会排斥和网络成瘾的负面结果，以及减轻和缓冲自我宽恕和正念的作用，为设计预防和干预服务以减少与网络相关的成瘾行为提供了重要意义。
