OBJECTIVE: Event centrality, identity, and trauma type may impact the symptoms of posttraumatic stress disorder (PTSD), although extant literature is still in nascent stages, particularly in low- and middle-income countries.
METHOD: This study examined the direct and indirect effects of event centrality, identity, and trauma type on PTSD among 276 college students in India (Mage = 19.05, SD = 0.91) analyzed using bivariate correlation and mediation analysis using a single group, cross-sectional, exploratory design. Trauma History Questionnaire, Centrality of Events Scale (CES), PTSD Checklist-Civilian-5, and Severity Indices in Personality Problems were used.
RESULTS: Event centrality showed strong correlation (ρ = .798) while self-control showed moderate correlation (ρ = .45) with PTSD symptoms. General disasters were found to be highly correlated with event centrality (ρ = .69) and PTSD symptoms (ρ = .68), while traumatic physical and sexual experiences were moderately correlated (CES: ρ = .42 and PTSD: ρ = .50). Indirect effects were mediated by event centrality and self-control between general disasters and PTSD symptoms (CES: β = 2.85, SE = 0.36, p < .001; self-control: β = 0.61, SE = 0.20, p < .01) and traumatic physical and sexual experiences and PTSD symptoms (CES: β = 1.92, SE = 0.62, p < .005; self-control: β = 01.05, SE = 0.43, p < .05). Direct effects were found between traumatic physical and sexual experiences and PTSD symptoms (β = 4.50, SE = 0.85, p < .001).
CONCLUSIONS: Event centrality and self-control may indirectly mediate the relationship between trauma type and PTSD symptoms. The implications for developing event centrality-focused interventions for PTSD targeting self-control are discussed. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
