Abstract
Previous research suggests that cognitive reappraisal (CR) and expressive suppression (ES) strategies of emotion regulation (ER) are associated with posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). How the patterns of these associations may vary in the context of event centrality (EC) however requires investigation to help delineate groups for whom the impact of event centrality may be more salient. We examined whether EC would moderate the associations of CR and ES with PTSD symptoms clusters and PTG domains among 388 emerging adults (18-30 year-olds) of Tiv ethnic group who were survivors of armed attack by Fulani herdsmen and were temporarily sheltered in two internally displaced persons’ (IDPs’) camps in North-central Nigeria. They completed self-report measures of the variables. Results indicated that EC strengthened the negative associations of CR and the positive associations of ES with avoidance, hyper-arousal and total PTSD symptoms, but not intrusion symptoms. For the PTG domains, EC only strengthened the positive association between CR and personal strength and weakened the association of ES with greater appreciation of life. These findings suggest that primary intervention programs that incorporate training of armed attack survivors in cognitive reappraisal strategy centered on the traumatic event could be effective in controlling PTSD but be less critical in engendering PTG. They also show that the psychological processes that underlie PTSD and PTG are related but involve nuances even within PTSD, and do not seamlessly set into the Janoff-Bulman's “strength through suffering” model of PTG. More research is required to test the model.
