Specific relationships between core beliefs and personality disorder symptoms in a non-clinical sample

The current study examined the relationship of clinically relevant core beliefs measured by the Young Schema Questionnaire-Short Form (YSQ-SF) to personality disorder (PD) symptoms in a large non-clinical sample (N = 804). Results indicated that the 15 YSQ-SF scales added sizeable explained variance (4% to 13%) to self-reported symptoms of 12 PDs, above variance explained by gender and symptoms of other PDs. In addition, several specific core beliefs related uniquely to individual PDs after controlling for the other core beliefs. Given that core beliefs related to personality disorder symptoms in a non-clinical sample of people at the typical onset age of PDs, it is possible that such beliefs might be important to understanding the development of PDs.
