Maladaptive use of internet and sleep problems is a significant health concern among adolescents. We aimed to understand better how sleep problems are related to suicidal ideation taking into account the presence of depression and internet addiction. 631 adolescents aged between 12 and 18 randomly recruited from different middle and high schools to complete self-report questionnaires assessing sleep disturbances, addictive use of the internet, depressive symptoms, and suicidal ideation. 22.9% of the sample reported on suicidal ideation during the month before the study, 42% of the sample suffer from sleep disturbances, 30.2% reported on the addictive use of the internet, and 26.5% exhibited severe symptoms of depression. Adolescents with suicidal ideation had higher rates of sleep disturbances, addictive use of internet and depressive symptoms. A confirmatory path analysis suggests that the effect of sleep disturbances on suicidal ideation moderated by the impact of internet addiction and mediated by the sleep effects on depressive symptoms. These results emphasize the importance to address the above risk behaviors in prevention curriculums programs. Future longitudinal studies are needed to determine the temporal order and to validate causal pathways.
