This study examined the comorbid effects of these variables. Data from wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions (N = 34,653) were used to examine using logistic regression the relationship between individuals with BPD (n = 562), PA (n = 253), PD (n = 255), comorbid BPD and PD (n = 146), and co-occurring BPD and PA (n = 119) who had attempted suicide. It was found that BPD, PD, and PA are associated with SAs. Comorbid PD and BPD, or PA and BPD, only slightly increased the association of BPD alone with SA. Associations were greatly decreased after controlling for affective dysregulation. These findings emphasize the importance of affective dysregulation in individuals with BPD in relation to suicide attempts. *Department of Psychology; †Department of Psychiatry; and ‡Department of Community Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada.
