Emotion dysregulation is a key feature of borderline personality disorder (BPD). Given the heterogeneity of BPD and emotion regulation, this study sought to define subgroups among a sample of young people with BPD based on their pattern of emotion regulation abilities. Baseline data from the Monitoring Outcomes of BPD in Youth (MOBY) clinical trial were used, in which 137 young people (Mage = 19.1, SDage = 2.8; 81% female) completed the self-report Difficulties in Emotion Regulation Scale (DERS), as a measure of emotion regulation abilities. Latent profile analysis (LPA) was conducted to identify subgroups, based upon response patterns on the six DERS subscales. Subsequent analysis of variance and logistic regression models were used to characterize the identified subgroups. LPA revealed three subgroups. A "low and unaware" (n = 22) subgroup, reporting the least emotion dysregulation, apart from high emotional unawareness. A "moderate and accepting" subgroup (n = 59), reporting high emotional acceptance within its own pattern, and moderate emotion dysregulation compared with the other subgroups. A "high and aware" subgroup (n = 56), reporting the highest level of emotion dysregulation, but with high emotional awareness. Some demographic, psychopathology, and functioning characteristics were associated with subgroup membership. The identification of distinct subgroups highlights the importance of considering the level of emotional awareness in the context of other regulatory abilities and suggests that therapies should not take a "one-size-fits-all" approach to emotion dysregulation. Future research should seek to replicate the identified subgroups given the relatively small sample size in the current study. In addition, examining the stability of subgroup membership and the influence upon treatment outcome will be interesting avenues for further exploration.
