Cumulative Trauma Exposure and Post-Traumatic Stress Symptoms among Older Adults in South Africa: Does Post-Traumatic Growth Moderate this Link?

The study explored the interplay between PTG and PTSS in older South African adults exposed to trauma. A quantitative cross-sectional design was employed. 195 participants from a low-resourced setting in South Africa were interviewed using the UCLA Life Adversities Screener, the PTSD Checklist (DSM-5), and the PTG-Inventory. Hayes Model SPSS Macro PROCESS for moderation was used. Overall, the relationship between cumulative trauma exposure and PTSS was moderated by the PTG level (b = -0.09, SE = 0.04, p = .0113). The findings suggest that cumulative trauma exposure is a significant predictor of PTSS, and the relationship is moderated by the threshold level of PTG. Higher levels of PTG mitigated the effect of cumulative trauma exposure on PTSS.
