IntroductionDrinking motives have shown meaningful associations with borderline personality disorder (BPD) features. However, it is unknown whether other common substances of abuse (namely cannabis and prescription opioids) have the same associations with BPD features. In the present study, we tested associations between BPD features and motives across three substances: alcohol, cannabis, and prescription opioids. The purpose of the study was to determine whether BPD showed similar patterns of associations across drugs, or whether some substances serve particular functions for individuals with BPD features, and whether this also varies by sex in a college student sample.MethodFive-hundred ninety-four college students completed online questionnaires measuring demographics, borderline personality disorder features, substance use, and substance specific motives for alcohol, cannabis, and prescription opioid use.ResultsBPD was most strongly associated with coping motives across all substances. For both alcohol and cannabis, this was true for both males and females, along with conformity motives. For prescription opioids, coping, social, enhancement, and pain motives were only significantly related to BPD features for females. When compared statistically, it was found that the associations with coping drinking motives and opioid pain motives were higher among females.ConclusionsThis pattern of results suggests that negatively reinforcing motives (coping and conformity) play a similar functional role in borderline personality and substance use disorder pathology for alcohol and cannabis, but for prescription opioids the negative reinforcement motives (coping and pain) were only evident in females.
