The Personality Beliefs Questionnaire in borderline personality disorder (PBQ-BPD): adaptation for Russian-speaking selection

Abstract

This study presents the results of the Personality Beliefs Questionnaire (PBQ-BPD; Butler, Brown, Beck, & Grisham, 2002) adaptation in the Russian-speaking sample of 608 people. The initial three-factorial structure of PBQ-BPD in the sample of 543 Internet users is confirmed. It is shown that 14 items form three factors: relating respectively to distrust (reflects the belief connected with expectation of exploitation and treachery), dependency (it is shown in the belief connected with feeling of helplessness without continued support) and protection (belief that one should act preemptively to avoid threat). The PBQ-SF scales showed good reliability and correlated significantly with psychopathological manifestations on SCL-90-R scale. Internal coherence and split reliability of the scale were checked in the sample of 608 people, and made up 0,893 and 0,784 respectively. Test-retest reliability of the questionnaire was established in group of 30 people and made up 0,754.
