Abstract
Purpose:The present study examined the joint impact of coping and rumination after trauma on post-traumatic growth(PTG)and posttraumatic depreciation(PTD)based on the PTG model.Methods:A cross-sectional study was conducted between October 2017 and May 2018.A sample of 253 individuals who had experienced a traumatic event in the last two years,was included.Participants completed an online self-reported survey,including demographic variables,trauma characteristics,the German Posttraumatic Growth and Depreciation Inventory-Expanded,the Brief COPE Inventory,and the Event Related Rumination Inventory.An analysis of correlation,a principal component analysis and hierarchical regression analyses were conducted.Statistical analyses were undertaken on SPSS(version 25.0;IBM,New York,USA).Results:After controlling for the effects of personal and trauma characteristics,self-sufficient coping and socially supported coping were found to favor the emergence of PTG.Event-related and recent deliberate rumination were positively related to PTG.Avoidant-focused coping and recent intrusive rumination were positively associated with PTD.Overall,the final models accounted for 46%and 58%of the variance in PTG and PTD.Conclusion:Our findings confirm the PTG model and support the central role of deliberate rumination,self-sufficient coping and socially supported coping in the development of PTG.Our results indicate that a similar model of PTD with comparable influencing factors can be assumed:if the individual is stuck in ongoing intrusive rumination and uses more avoidance-focused coping,it might lead to more reports of PTD.
