    08/05/2025

    With the increase in technology use by youth in recent decades, there is a need to examine how the overuse of technology influences youth mental health and wellbeing. The purpose of this study was to examine the association between problem technology use and psychological distress in a representative sample of adolescents residing in Ontario, Canada. Findings from this study show that problem technology use is strongly associated with psychological distress in adolescents, with stronger associations in males than females. Appropriate intervention strategies are needed to mitigate the adverse effects of technology use among secondary school students.
