Problematic Internet use (PIU) has been empirically identified as a risk factor for future psychotic-like experiences (PLEs) among adolescents. This study aimed to examine the short-term predictive role of PIU on PLEs in adolescents and investigate their underlying mechanisms, focusing on the mediating role of sleep disturbance and the moderating role of psychological resilience. A total of 27,260 Chinese adolescents (52.2 % males, Mean = 14.33 ± 1.49) were included for analyses in this two-wave longitudinal study conducted six months apart. The baseline survey (time 1, T1) was between December 17 and 26, 2021, and the follow-up survey (time 2, T2) was between May 17 and June 5, 2022. Participants reported their socio-demographics, T1 PIU, T1 sleep disturbance, T1 resilience, T1 PLEs, T2 PLEs, and T2 negative life events. After controlling for socio-demographics, T1 PLEs, and T2 negative life events, T1 PIU exacerbated T2 PLEs directly and indirectly through T1 sleep disturbance, with T1 resilience moderating both parts of the mediation pathway. These findings provide novel insights into the mechanisms linking PIU to PLEs among adolescents and offer valuable implications for clinical practice and school policy. age
