Borderline Personality Disorder (BPD) is a complex mental health condition, often marked by intense emotional dysregulation and relational difficulties. Dialectical Behaviour Therapy (DBT) is a widely recognised, evidence-based approach for BPD, yet how its principles are being adapted within music therapy is not well understood. As music therapy increasingly contributes to mental health care, understanding how DBT is being adapted can inform training, interdisciplinary work, and service development. This study explores how Registered Music Therapists (RMTs or similar) in the Asia-Pacific region apply DBT-informed music therapy approaches in their work with individuals diagnosed with BPD or experiencing emotional dysregulation. It aims to identify current practices, training pathways, perceived benefits, and clinical challenges. A mixed-methods survey was conducted with RMTs, gathering both quantitative and qualitative data on DBT-related training, use of DBT core skills (mindfulness, emotion regulation, distress tolerance, interpersonal effectiveness), and clinical outcomes. Early findings highlight a variety of flexible and creative approaches. RMTs describe integrating DBT skills through improvisation, songwriting, lyric analysis, and structured interventions. While some practitioners have formal DBT training, many rely on self-directed learning. Common challenges include limited training access and a need for clearer models of integration. Despite these barriers, therapists consistently emphasise music’s unique role in fostering emotional safety, self-expression, and client engagement. This presentation shares key findings and reflects on how music therapists are actively shaping DBT-informed practice. In doing so, it contributes to the growing evidence base, supports professional development, and strengthens the role and identity of music therapy within contemporary mental health care.
