Stressful life events and adolescent Internet addiction: The mediating role of psychological needs satisfaction and the moderating role of coping style.

Although stressful life events have been shown to play an important role in adolescent Internet addiction, little is known about mediating and moderating mechanisms underlying this relation. Based on the integration of self-determination theory and stress-coping theory, the present study investigated (a) the mediating role of psychological needs satisfaction in the relationship between stressful life events and Internet addiction, and (b) the moderating role of coping style in the indirect and direct relationships between stressful life events and Internet addiction. This model was tested with 998 Chinese adolescents (mean age = 15.15 years, SD = 1.57). Participants filled out questionnaires regarding stressful life events, psychological needs satisfaction, coping style, and Internet addiction. After demographic variables were controlled, stressful life events were significantly positively associated with Internet addiction. Mediation analysis revealed that psychological needs satisfaction partially mediated the association between stressful life events and Internet addiction. Moderated mediation analysis further indicated that the mediated path was weaker for adolescents with higher levels of positive coping style. These findings underscore the importance of identifying the mechanisms that moderate the mediated paths between stressful life events and adolescent Internet addiction.
