VALIDATING AND EXTENDING THE BIOSOCIAL MODEL OF BORDERLINE PERSONALITY DISORDER. ScholarBank@NUS Repository. | Abstract: | The biosocial theory of borderline personality disorder (BPD) posits that the reciprocal transactions between an individual’s biological vulnerabilities and an invalidating environment give rise to BPD symptoms. My dissertation aimed to validate and extend the biosocial model via three studies. Results from the meta-analysis indicated small to moderate effect sizes for the association between parental invalidation and BPD symptoms. Findings from a one-year longitudinal study with three six-monthly time points provided empirical evidence for the prospective relations between components of the biosocial model and BPD symptoms, and the reciprocal relationship between parental invalidation and emotional vulnerability. Lastly, I demonstrated that parental invalidation could transmit across generations, with difficulties in emotion regulation acting as the mediator for transmission for mothers. Overall, the results support the propositions of the biosocial model and highlight the importance of contextualizing the model in broader familial and socio-cultural contexts. | URI: | https://scholarbank.nus.edu.sg/handle/10635/210199 |
