School burnout is a worldwide issue that affects adolescents at every academic level. Despite the significant impact of this issue on adolescents' mental health and academic performance, few studies have examined its influence on mind wandering and its underlying mechanisms. This research endeavors to address this knowledge gap by examining the mediating role of Internet addiction in the relationship between school burnout and mind wandering and the moderating role of resilience among 2329 Chinese adolescents (Mage = 14.9 years, SD = 1.73) through an online questionnaire assessment. Participants completed measures of school burnout, Internet addiction, resilience, and mind wandering, which were analyzed using structural equation modeling (SEM) with SPSS 23.0 and Mplus 8.0. Results demonstrated that school burnout was positively linked with mind wandering, while Internet addiction mediated this relationship. Additionally, resilience moderated the association between Internet addiction and mind wandering. These findings significantly improve our comprehension of the consequences of mind wandering and offer valuable insights into possible intervention approaches for adolescents experiencing this phenomenon.
