Physical Health, Childhood Trauma and Suicide Risk: Psychosocial Stress and Interpersonal Conflicts as Mediators

Objective: Suicide risk represents a critical form of self-harm with significant implications for both general and clinical populations. The present study aimed to investigate the structural relationships between physical health, childhood trauma, and suicide risk, with a particular focus on the mediating roles of psychosocial stress and interpersonal conflicts. Methods: This cross-sectional descriptive study utilized structural equation modeling (SEM) to analyze the proposed relationships. We recruited ۴۰۰ participants aged ۱۸ to ۵۰ years from Tehran and Alborz provinces, Iran, using convenience sampling. participants completed the childhood trauma questionnaire (CTQ), psychosocial stress questionnaire, interpersonal conflict questionnaire, physical health questionnaire, and suicide probability scale (SPS). data were analyzed using multiple regression and SEM via SPSS software, version ۲۶ and AMOS software, version ۲۴. Results: The measurement model demonstrated an acceptable fit to the data (the chi-square to degrees of freedom [CMIN/df]=۳.۱۵۹, the comparative fit index [CFI]=۰.۹۲۰, the root mean square error of approximation [RMSEA]=۰.۰۷۹). The fit indices for the structural model were also satisfactory (CMIN/df=۳.۵۱, CFI=۰.۹۱۸, RMSEA=۰.۰۷۹). Physical health exhibited a significant negative association with suicide risk (β=-۰.۲۱۷, P=۰.۰۰۳), while childhood trauma showed a significant positive association (β=۰.۳۸۵, P<۰.۰۰۱). Bootstrap analyses confirmed that psychosocial stress and interpersonal conflicts significantly mediated the relationships between both physical health and childhood trauma and suicide risk (-۰.۰۶۷, ۰.۱۶۵, -۰.۰۳۲, ۰.۰۵۷; P<۰.۰۵). Conclusion: These findings underscore the crucial roles of poor physical health and early-life adversity in conferring risk for suicide; effects that are significantly mediated by psychosocial stress and interpersonal difficulties. The results carry important implications for the development and implementation of targeted, multi-component interventions aimed at mitigating suicide risk.
