Post accidental injury: Mediating roles of emotional expressivity, rumination, and posttraumatic growth.

This study explored the relationship between rumination (deliberate or intrusive), emotional expressivity (positive or negative), and posttraumatic growth among patients within 1 month after an accidental injury. Using a cross-sectional design, 313 patients were investigated in two comprehensive hospitals. The results revealed that intrusive rumination had a significant positive effect on posttraumatic growth, partly through four different pathways: (i) the mediating role of deliberate rumination; (ii) the chain mediating role of deliberate rumination and negative emotional expressivity; (iii) the chain mediating role of negative emotional expressivity and positive emotional expressivity; and (iv) the chain mediating role of negative emotional expressivity, positive emotional expressivity, and deliberate rumination. Interventions to encourage emotional expressivity and facilitate the transition from intrusive rumination to deliberate rumination may promote posttraumatic growth soon after an accidental injury.
