Biosocial theory in DBT (Dialectical Behavior Therapy) is a theoretical framework that aims to understand the development and maintenance of borderline personality disorder (BPD) and other complex mental health conditions. 

The theory suggests that both biological factors (such as genetics and neurobiology) and environmental (social and cultural) factors contribute to the development of emotional dysregulation, impulsivity, and interpersonal difficulties.

According to the biosocial theory, individuals may have a heightened sensitivity to emotional stimuli, but a decreased ability to regulate their emotions.

This sensitivity is believed to be partly due to genetic factors, and the emotional dysregulation may be triggered or exacerbated by environmental factors such as traumatic life experiences.

DBT emphasizes the importance of understanding and addressing both genetic and environmental factors in the treatment. 

The therapy focuses on building skills for emotional regulation, distress tolerance, mindfulness, and interpersonal effectiveness, as well as addressing the underlying causes of emotional dysregulation and impulsivity.

How does Biosocial Theory help Highly Sensitive People?

When therapists apply DBT and believe the tenets of Biosocial Theory, they are aware and sensitive to the interplay between biological and environmental factors in shaping our behavior and personality. In the context of highly sensitive people (HSPs), Biosocial Theory suggests that sensitivity is not just a genetic trait but also shaped by environmental factors such as parenting style and early life experiences.

According to Biosocial Theory, HSPs have a more sensitive nervous system that processes information more deeply and extensively than non-HSPs. 

This biological trait can shape their personality and behavior by increasing their awareness of stimuli in their environment, making them more sensitive to emotional cues, and increasing their capacity for empathy and introspection. 

However, Biosocial Theory suggests that HSPs' sensitivity is also shaped by environmental factors such as parental attitudes toward emotional expression, the availability of emotional support during their formative years, and their cultural background.

For example, if an HSP grows up in an environment where emotions are suppressed or dismissed, they may develop coping mechanisms such as social withdrawal or people-pleasing to avoid rejection and conflict. 

As a result, Biosocial Theory suggests that HSPs' sensitivity is not a one-dimensional trait but rather a complex interplay of biology and environment. 

If you suspect that you or your loved one may meet the criteria for HSP or BPD, please reach out to speak to a clinician trained in DBT and Biosocial Theory.  Understanding the role of both biological and environmental factors in shaping sensitivity can help all unique humans develop effective coping strategies and enhance their well-being.
