Posttraumatic stress disorder, insomnia, depression, and healthrelated quality of life in Chinese soccer players: Resilience as a moderator

This study examined the relationships among posttraumatic stress disorder (PTSD), insomnia, depression, and health-related quality of life (HRQoL) in Chinese soccer players, and investigated the moderating role of resilience in these relationships. Respondents (n = 356) completed the Short-Form PTSD Checklist-5, Insomnia Severity Index, Patient Health Questionnaire-9, 12-Item Short Form Health Survey, and Connor-Davidson Resilience Scale. Structural equation and simple slope analyses were performed using SPSS 26.0 and Amos 26.0. The results showed that PTSD had a significant negative impact on HRQoL in soccer players. Insomnia and depression acted as chain mediators between PTSD and HRQoL, and resilience inversely moderated the effects of insomnia on depression, as well as attenuating the negative impact of depression on HRQoL. These findings provide a theoretical basis for relevant government departments, experts, and coaches to develop and adopt effective interventions.
