Linehan's Biosocial Theory

Linehan's Biosocial Theory explains that Borderline Personality Disorder (BPD) arises from a combination of biological vulnerability and an invalidating environment. Some individuals are naturally more emotional or sensitive, making it harder to regulate feelings. When these individuals grow up in environments that dismiss or punish their emotions, they learn to doubt their feelings and struggles to manage intense emotions. This interaction creates a cycle of emotional instability and difficulty in relationships. The theory highlights that both innate temperament and external circumstances contribute to BPD, emphasizing the importance of understanding and addressing both aspects in treatment.
