Association among self-compassion, childhood invalidation, and borderline personality disorder symptomatology in a Singaporean sample

Background Linehan's biosocial theory posits that parental invalidation during childhood plays a role in the development of borderline personality disorder symptoms later in life. However, little research has examined components of the biosocial model in an Asian context, and variables that may influence the relationship between childhood invalidation and borderline symptoms. Self-compassion is increasingly regarded as an adaptive way to regulate one's emotions and to relate to oneself, and may serve to moderate the association between invalidation and borderline symptoms. The present study investigated the association among childhood invalidation, self-compassion, and borderline personality disorder symptoms in a sample of Singaporean undergraduate students. Methods Two hundred and ninety undergraduate students from a large Singaporean university were recruited and completed measures assessing childhood invalidation, self-compassion, and borderline personality disorder symptoms. Results Analyses using multiple regression indicated that both childhood invalidation and self-compassion significantly predicted borderline personality disorder symptomatology. Results from moderation analyses indicated that relationship between childhood invalidation and borderline personality disorder symptomatology did not vary as a function of self-compassion. Conclusion This study provides evidence in support of aspects of the biosocial model in an Asian context, and demonstrates a strong association between self-compassion and borderline personality disorder symptoms, independent of one's history of parental invalidation during childhood.
