Abstract :Objective: This study aimed to examine the mediating role of sleep quality in the relationship between digital game addiction and cyberbullying behaviours among adolescents. Materials and Methods: The study employed a cross-sectional and correlational design and was carried out between May 1 and June 20, 2025. A total of 504 adolescents aged between 15 and 18 and residing in an eastern province of Türkiye participated in the study. Data collection tools included the Socio-Demographic Information Form, Digital Game Addiction Scale, Pittsburgh Sleep Quality Index (PSQI), and the Cyberbullying Inventory-II. Statistical analysis was conducted using descriptive statistics, Pearson correlation tests, and Structural Equation Modeling via path analysis. Results: Digital game addiction showed statistically significant positive correlations with sleep quality scores, cyberbullying, and cyber victimization (p<0.001). Path analysis revealed that digital game addiction was a significant predictor of both sleep quality and cyberbullying behaviors. Sleep quality demonstrated a significant mediating effect in the pathway between digital game addiction and cyber victimization (β=0.055; p=0.015), but no significant mediation was found regarding cyberbullying (β=–0.017; p=0.697). Conclusions: Adolescents with higher levels of digital game addiction may experience poorer sleep quality, which in turn can elevate their risk of cyber victimization. The findings suggest that sleep quality partially mediates the connection between digital game addiction and cyberbullying. These outcomes underline the importance of implementing educational strategies that address both digital media use and sleep hygiene to help prevent cyberbullying among youth.
