The Effects of Comprehending Social Support on Personality Traits and Post-traumatic Growth among Wenchuan Earthquake Residents: A Moderated Mediation Model
Objective: Exploring the mediating role of navigating social support between personality traitsand posttraumatic growth, and the moderating role of PTSD on mediation. Methods: The CPAI shortversion questionnaire, the Perceived Social Support Scale (PSSS), the civilian version of the PosttraumaticStress Disorder Checklist (PCL-C), and the Post-Traumatic Growth Inventory (PTGI) were used tosurvey 200 people in the disaster area 15 years after the Wenchuan earthquake. Results: (1) Significantpositive correlations were found between all four personality traits and Appreciative Social Support; onlyInterpersonal Orientation was significantly positively correlated with PTSD; Leadership, InterpersonalOrientation Personality, and Appreciative Social Support were significantly positively correlatedwith Posttraumatic Growth. (2) Appreciating social support fully mediated the effect of reliability onposttraumatic growth (β = -0.087, t = -4.859, p < 0.001, 95% CI = [-0.122, -0.052]). (3) PTSD moderatedthe direct (ΔR2 = 0.11, F = 26.81, p < 0.001) and indirect (ΔR2 = 0.03, F = 7.77, p < 0.01) effects of reliabilityon posttraumatic growth (β = -0.087, t = -4.859, p < 0.001, 95% CI = [-0.122, -0.052]). Conclusion:Personality traits of post-earthquake victims can influence post-traumatic growth through navigatingsocial support, and a mediational model of PTSD moderating both the effects of personality traits onnavigating social support and personality traits on post-traumatic growth with moderation holds.
