The associations between coping self-efficacy and posttraumatic stress symptoms 10 years postdisaster: differences...

The mediating role of coping self-efficacy (CSE) perceptions between disaster-related posttraumatic stress symptoms (PSS) in the intermediate term (4 years postevent) and PSS in the long term (10 years postevent) were examined. Participants were 514 adult Dutch native residents affected by the Enschede fireworks disaster. The disaster (May, 2000) was caused by a massive explosion in a fireworks storage facility that destroyed a residential area. Multiple regression analysis and path analysis were used to examine the mediating role of CSE and whether the mediating role was the same for men and women. Age, education, disaster exposure, home destruction, optimism, and stressful life events were also taken into account. Regression analysis showed that the former variables were not associated with PSS at 10 years postevent, in contrast to PSS at 4 years, and were therefore omitted from the path analyses. CSE assessed at 10 years postdisaster partially mediated the relationship between PSS at 4 and PSS at 10 years postdisaster. Post hoc multigroup analysis showed that this effect was significantly stronger for men, whereas the association between PSS at 4 and 10 years postevent was stronger for women. PSS at 10 years postevent were better predicted among men (explained variance 59.5% vs 50.8%).
