Implication
Observational study reveals sleep problems mediate earthquake-related PTSD symptoms in adolescents, highlighting resilience as a protective buffer.
Key Points
- To examine whether sleep problems mediate the relationship between earthquake trauma exposure and PTSD symptoms among adolescents, and whether psychological resilience moderates this pathway.
- Survey administration assessed 1,342 adolescents (mean age = 15.54 years, SD = 1.26) 12 months after a devastating earthquake in China.
- Self-report questionnaires evaluated earthquake exposure, sleep problems, resilience, and PTSD symptoms while controlling for demographic variables using moderated mediation analysis.
- Earthquake exposure was significantly and positively associated with PTSD symptoms, with sleep problems partially mediating the relationship.
- Resilience moderated the direct relationship between earthquake exposure and PTSD symptoms, rendering the association significant only for adolescents with lower levels of resilience.
- Resilience moderated the indirect path, showing that the positive association between sleep problems and PTSD symptoms was stronger among adolescents with low resilience.
