The Personality Beliefs Questionnaire-Short-Form: Relationship of Personality Disorders Schemata with Entitlement and Dysfunctional Thoughts

The Personality Beliefs Questionnaire-Short Form (PBQ-SF), designed to assess dysfunctional beliefs based on Beck et al.'s (1990) cognitive formulations of personality disorders, has received little attention in research. The present study assessed the construct validity of the PBQ-SF by exploring its relations with conceptually relevant scales-the Psychological Entitlement Scale and the Warpy Thoughts Entitlement, Relationship, and Achievement subscales. Participants were 228 college students. Analyses using ipsatized scores indicated that dysfunctional entitlement beliefs were highly characteristic of individuals who endorsed antisocial and narcissistic beliefs, but minimally characteristic of individuals endorsing dependent beliefs. Dysfunctional relationship beliefs were least characteristic of individuals who endorsed narcissistic and schizoid beliefs, but most characteristic of those who endorsed borderline beliefs. Dysfunctional achievement schemata were most characteristic of individuals who endorsed obsessive-compulsive beliefs. Consistent with Butler et al.'s findings, our results support the convergent validity of PBQ-SF average score as a measure of general dysfunctional beliefs.
