Borderline personality disorder (BPD) is a mental health condition characterized by emotion dysregulation, interpersonal impairment, and high suicidality. Dialectical behaviour therapy (DBT) is the most widely studied psychotherapeutic treatment for BPD. To date, the vast majority of DBT research has focused on cisgender women, with a notable lack of systematic investigation of sex and/or gender differences in treatment response. In order to encourage effective, equitable treatment of BPD, further investigation into treatment targets in this population is critical. Here, we employed a systematic strategy to delineate gaps in the DBT literature pertaining to sex and gender differences and propose directions for future research. Findings demonstrate a significant discrepancy in measurement of sex and gender, particularly among gender-diverse individuals. Exploring DBT treatment response across the full spectrum of genders will facilitate the provision of more tailored, impactful care to all individuals who suffer from BPD.
Key learning aims(1) To date, DBT treatment literature has focused almost exclusively on cisgender women, with only two of 253 DBT studies in current literature accounting for transgender and gender diverse (TGD) individuals.
(2) Recognize how gender minority stress may impact the prevalence of BPD among TGD individuals.
(3) Learn how future research initiatives can be employed to rectify this gap in the DBT literature.
