Psychotic-Like Experiences and Suicidal Ideation Among Adolescents: The Chain Mediating Role of Insomnia Symptoms and Resilience

Background: Individuals who experience psychotic-like experiences (PLEs) are at significant risk of suicide-related behaviors. This two-wave longitudinal study aimed to investigate the relationships among PLEs, insomnia symptoms, resilience, and suicidal ideation (SI) among adolescents.Methods: A total of 2231 college students [mean age (standard deviation) = 20.02 (1.39) years] completed two web-based surveys. Participants completed self-report measures of sample characteristics, PLEs, insomnia symptoms, resilience, and SI.Results: The findings indicated a significantly positive correlation between PLEs and SI that was sequentially mediated by insomnia symptoms and resilience. Furthermore, insomnia symptoms and resilience played a chain-mediating role between PLEs and adolescent SI.Conclusion: These findings suggest potential mechanism for the PLEs-SI link, which helps us better understand how PLEs can influence individual SI and provides important information for early prevention.

This two-wave longitudinal study aimed to investigate the relationships among PLEs, insomnia symptoms, resilience, and suicidal ideation (SI) among adolescents. The findings revealed a significant positive correlation between PLEs and SI, which was sequentially mediated by insomnia symptoms and resilience. Additionally, insomnia symptoms and resilience played a chain-mediating role between PLEs and adolescent SI. These findings provide important insights into the mechanisms of the PLEs-SI link and contribute to early prevention efforts.
