Research has shown that people sometimes report self-perceived growth as a result of dealing with a potentially traumatic event, but relatively few methodologically rigorous studies have examined whether perceived posttraumatic growth is associated with improved subsequent well-being across a wide range of outcomes. In this three-wave longitudinal study of Colombian emerging adults, we examined the associations of perceived posttraumatic growth with 17 well-being outcomes across domains of psychological well-being, psychological distress, social well-being, physical well-being, and character strengths. Using an outcome-wide (...) analytic design that adjusted for a range of covariates assessed in Wave 1, we found that overall perceived posttraumatic growth assessed in Wave 2 was robustly associated with improvements in one or more facet of each well-being domain assessed approximately six months later in Wave 3. Our findings suggest that perceived posttraumatic growth may contribute to individual well-being over the longer-term. (shrink)
