Emotion Dysregulation and Vulnerability to Suicidal Ideation and Attempts

This study investigated the predictive utility of a six-dimensional conceptualization of emotion dysregulation for suicidal ideation, as well as its ability to distinguish among individuals with differing histories of suicidality. Young adults (N = 96) with current suicidal ideation but no suicide attempt history (n = 17), a history of a single (n = 20) or multiple attempts (n = 17), or no current ideation/no past attempts (n = 42) completed measures of emotion dysregulation, suicidal ideation, depression, hopelessness, and a diagnostic interview. Multiple suicide attempters differed from participants with no suicidal ideation/no past attempts on two emotion dysregulation dimensions-nonacceptance of emotional responses and perceived limited access to emotion regulation strategies. After adjusting for depression symptoms and the presence of a mood or anxiety diagnosis, limited access to emotion regulation strategies significantly predicted current suicidal ideation, a relation that was found to be statistically mediated by hopelessness.
