本研究探讨了人格信念问卷（PBQ）的结构，自我报告的工具，旨在评估与人格病理功能失调的信念，提出了人格功能障碍的认知理论。采用探索性因素分析和验证性因素分析分别对438例抑郁症门诊患者和683例寻求治疗的精神病门诊患者的PBQ进行了研究。所有参与者都使用标准临床访谈进行人格障碍评估。在合并样本（N=1121）中，通过检查有和无人格障碍诊断的患者的PBQ评分，评估所得到的因素结构的有效性。探索性和验证性分析表明，PBQ最好由7个经验确定的因素描述：6评估与DSM-IV中承认的人格病理形式相关的功能失调信念。有效性分析显示，那些被诊断为人格障碍的人在所有因素上的平均得分都高于那些没有这些障碍的人。被诊断患有特定DSM-IV人格障碍的患者亚组在与其各自诊断相关的因素上的平均得分高于所有其他因素。结果的模式对人格病理学的概念化有影响。据我们所知，还没有正式的诊断或评估系统系统将功能失调信念的作用系统地纳入其对人格病理学的描述中。功能失调的信念的识别可能不仅有助于概念化的情况下，但可能提供独特的心理治疗的目标。未来的人格病理评估系统的建议。
This study examines the structure of the Personality Belief Questionnaire (PBQ), a self-report instrument designed to assess dysfunctional beliefs associated with personality pathology, as proposed by the cognitive theory of personality dysfunction. The PBQ was examined using exploratory factor analysis with responses from 438 depressed outpatients, and confirmatory factor analysis with responses from 683 treatment-seeking psychiatric outpatients. All participants were assessed for personality disorder using a standard clinical interview. The validity of the resulting factor structure was assessed in the combined sample (N=1121) by examining PBQ scores for patients with and without personality disorder diagnoses. Exploratory and confirmatory analyses converged to indicate that the PBQ is best described by 7 empirically identified factors: 6 assess dysfunctional beliefs associated with forms of personality pathology recognized in DSM-IV. Validity analyses revealed that those diagnosed with a personality disorder evidenced a higher average score on all factors, relative to those without these disorders. Subsets of patients diagnosed with specific DSM-IV personality disorders scored higher, on average, on the factor associated with their respective diagnosis, relative to all other factors. The pattern of results has implications for the conceptualization of personality pathology. To our knowledge, no formal diagnostic or assessment system has yet systematically incorporated the role of dysfunctional beliefs into its description of personality pathology. The identification of dysfunctional beliefs may not only aid in case conceptualization, but may provide unique targets for psychological treatment. Recommendations for future personality pathology assessment systems are provided.
