Emotion regulation difficulties are associated with nightmares and suicide attempts in an adult psychiatric inpatient sample.

Although many studies have examined potential moderators of the relation between nightmares and suicide, few have examined emotion regulation, particularly utilizing severe populations such as psychiatric inpatients. The present study sought to investigate whether emotion regulation difficulties are associated with nightmares and suicide attempts in an inpatient sample. We included 2,683 psychiatric inpatients ranging from 18 to 81 years (M = 34.35, SD = 14.70). Nightmare frequency, emotion regulation difficulties, and their interaction predicted previous suicide attempts. Limitations include the homogeneity and cross-sectional nature of the sample. Suggestions for future study are discussed.
