Mini Workshop 19 - Transdiagnostic Applications of the Biosocial Model: Explaining Emotion Dysregulation with Behavioral Science and Validation

The biosocial model in dialectical behavior therapy (DBT) provides a powerful framework for understanding emotion dysregulation. It describes a transactional cycle between high emotional vulnerability and chronic invalidation, shaping difficulties in emotion regulation over time. While DBT conceptualizes borderline personality disorder as a disorder of the emotion regulation system, emotion dysregulation is a transdiagnostic process affecting a wide range of individuals. As such, effectively explaining the biosocial model to patients and families is a crucial clinical skill that can enhance treatment engagement, reduce stigma, and promote a shared understanding of emotional difficulties.

This interactive mini workshop will provide a concise review of the biosocial model, including its research foundation and clinical applications. Through live demonstrations and role plays, participants will practice explaining the model in ways that are accessible, affirming, and relevant to adults, adolescents, and families. The workshop will also examine how the biosocial model applies across various symptom profiles and explore different forms of invalidation, including the impact of trauma and systemic oppression. Common barriers—such as emotional intensity, defensiveness, and dysregulation—can make orientation to the model challenging. This workshop will equip clinicians with practical strategies grounded in behavioral science and validation to navigate these hurdles, fostering greater patient and family engagement.
