Objective: To examine the prevalence of embitterment by following individuals over time and to statistically evaluate how factors known as correlates of embitterment affect different groups with or without changes in embitterment over time. Method: Responses for the posttraumatic embitterment disorder (PTED)self-rating Scalewere collected from the same 1,153 adults who participated in afollow-up survey delivered 14 months apart. Suggested cutoff points were applied to identify changes in embitterment and four groups were iden- tified. For each group, the relative impacts of factors that affect changes in or maintenance of embitterment, such as negative life events (NLEs), belief in a just world (BJW), social support, relative deprivation, and resilience, were statistically analyzed. Results: The average PTED scores were relatively high for both sur- veys (M = 1.73 and 1.58, respectively). “Persistent” or “increased” in embitterment was seen for 47.3% of the participants. In particular, 15.3% (Wave 1) and 12.1% (Wave 2) of participants experienced clinically relevant levels of embitterment. NLEs, BJW, relative deprivation, and resilience showed significant associ- ations with the risk of persistence or deterioration of embitterment. Conclusions: Our study highlights embitterment as a dynamic emotion that can either be aggravated or moderated over time. Embitterment can be elicited by joint effects of multiple social and interactional factors including known embitterment correlates, and relative deprivation is confirmed as a possible core elicitor of embitterment in the context of comparative justice. These findings imply that additional longitudinal research and development of prac- tices for mental health prevention in general populations are needed.
