Issues in the assessment and conceptualization of personality disorders

This article reviews several current issues associated with the definition and assessment of personality disorders (PDs) as defined in the third and fourth editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Specifically reviewed are issues associated with classification, PD conceptualizations, and the assessment of these disorders. DSM PD categories are also reviewed in terms of their psychometric properties. A review of the PD assessment literature suggests that DSM conceptualizations and definitions of PDs are problematic at both conceptual and quantitative levels. This article concludes with suggestions for possible alternative approaches to and modifications of DSM PD assessment.
