Abstract
The current study analyzed the posttraumatic growth process based on the posttraumatic growth model developed by Tedeschi and Calhoun(2004). In particular, the internal mechanisms at work within individuals who experienced traumatic events were examined with the aim of identifying the triple mediation effects on posttraumatic growth and establishing whether optimism has a moderation effect on posttraumatic growth. A total of 450 adults, including undergraduates, completed questionnaires. From these, 384 were considered to have had experienced trauma and were recruited for the current study. In order to analyze posttraumatic growth process, all participants completed a basic survey questionnaire, a trauma questionnaire, the Posttraumatic Growth Inventory(PTGI), the Korean version of the Event Related Rumination Inventory(K-ERRI), the Korean version of the Difficulties in Emotion Regulation Scale(K-DERS), and the Life Orientation Test-Revised(LOT-R). The results are as follows. First, an examination of the triple mediation effects between trauma and posttraumatic growth indicated that trauma had a positive effect on posttraumatic growth through difficulties in emotion regulation, the next intrusive rumination, and then deliberate rumination. In addition, trauma influenced posttraumatic growth through intrusive rumination and deliberate ruination. Accordingly, it can be said that intrusive rumination and deliberate rumination are necessary to posttraumatic growth. Second, an examination of the mediating role of optimism on the effect of trauma on posttraumatic growth indicated that optimism has a moderation effect between deliberate rumination and posttraumatic growth. However, no moderation effects of optimism were found between trauma and posttraumatic growth, difficulties in emotion regulation and posttraumatic growth, or between intrusive rumination and posttraumatic growth. The practical significance and limitations of the current study were discussed, and suggestions for future research were provided.
