Positive Emotion Dysregulation in Posttraumatic Stress Disorder.

Although PTSD is associated with both emotion regulation (ER) difficulties and persistent difficulties experiencing positive emotions, research concerning positive ER in PTSD is still scarce. We aimed to clarify whether PTSD patients show dysfunctional responses to positive emotions and whether positive ER is associated with PTSD symptom severity. PTSD patients (N = 59) were compared to healthy controls (HC, N = 58) with respect to their self-reported regulation of positive and negative emotions. We used the Responses to Positive Affect Questionnaire to assess positive ER and the Difficulties in Emotion Regulation Scale and Response Styles Questionnaire to assess negative ER. PTSD patients showed deficient negative as well as deficient positive ER as compared to HC. Both dampening of positive emotions as well as positive rumination were associated with self-reported symptom severity. Furthermore, dampening contributed to the prediction of PTSD symptom severity beyond depressive symptoms and negative rumination. This study supports and expands previous findings of dysfunctional positive ER in PTSD. Further research is needed to clarify whether deficits in positive ER contribute to the onset and maintenance of PTSD. If so, therapeutic approaches should aim to help PTSD patients build up adequate skills to handle positive emotions in PTSD.
