Applications of dialectical behavioural therapy in the perinatal period: A scoping review

Psychological distress is the most common complication of pregnancy. High-risk concerns can include severe emotion dysregulation, suicidality and self-injury, and health risk behaviours, which bear substantial consequences for caregivers and families. Yet, effective, comprehensive interventions for high-risk caregivers have received limited attention. Dialectical behaviour therapy (DBT) is a frontline treatment for such concerns. Accordingly, we conducted a scoping review on the implementation of DBT in the perinatal period. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Seven studies were identified; study designs included case studies and single-arm pilot trials. Most studies used DBT-informed protocols with significant adaptations, few included multiple components of DBT (i.e. skills group, individual therapy, phone coaching and consultation team), and none met criteria for adherent delivery of all four modes of DBT treatment. Findings suggest DBT-informed interventions may be successfully implemented to treat a range of perinatal mental health symptoms, including borderline personality disorder, depression, anxiety, and post-traumatic stress, and to promote emotion regulation and positive parenting behaviours. While results provide preliminary support for perinatal DBT, this literature is scant and empirical rigour considerably lacking. Clinical implications and future directions are outlined to aid researchers and providers in addressing the ongoing perinatal mental health crisis and developing sorely needed interventions to address the needs of high-risk caregivers.
