摘要

Over the last few years, Lebanese adolescents have survived multiple traumatic events, including continuous conflict and political instability, a spiraling economic crisis, the COVID-19 pandemic, the 2020 Beirut port blast, and the February 2023 earthquake. These repetitive exposures to trauma have put this vulnerable group at a high risk for developing a variety of mental health issues, including post-traumatic stress symptoms (PTSS) and psychotic experiences (PEs). Community-based research on PEs following multiple trauma exposure offers the opportunity to extend our understating of the stress-vulnerability model of schizophrenia, and how severe stress may affect mental health. The present study aimed at testing the hypothesis that insomnia severity mediates the relationship from PTSS to PEs in Lebanese adolescents (aged 12–18 years), 4–6 weeks after the February 2023 earthquake. This was a web-based, cross-sectional study. A total of 546 community adolescents from Lebanon were enrolled (mean age 15.76 ± 1.65 years, 60.1% females). We found a prevalence of PTSS, insomnia and PEs of 21.4%, 45.8% and 51.1% respectively. Insomnia severity mediated the association between PTSS and PEs (indirect effect: Beta = .03; Boot SE = .01; Boot CI .02; .05). Higher PTSS was significantly associated with more insomnia severity and directly associated with more PEs. Finally, higher insomnia severity was significantly associated with more PEs. Findings confirm the partial mediating effects of insomnia between PTSS and PEs, preliminarily suggesting sleep problems as a promising modifiable factor for reducing the risk for developing psychotic symptoms in the aftermath of natural disasters among vulnerable individuals. Given that, this is the first study to examine insomnia as mediator between PTSS and PEs, the present findings should be considered tentative pending future longitudinal research in larger populations and different settings.
