title: Patient Impairment Lexicon: a psychometric analysis.
abstract: Growth in managed care has magnified the needs for assessment of treatment efficacies and standardized communication regarding treatment needs. Addressing both needs requires a common terminology describing the scope of treatable mental health impairments. The Diagnostic and Statistical Manual of Mental Disorders-IV provides a common categorical language for describing clinical disorders, but its categories are not discrete and do little to facilitate communication regarding specific treatment needs. Goodman, Brown, and Deitz developed a Patient Impairment Lexicon intended to address these limitations. The current vignette study provided initial psychometric assessment of this nomenclature, specifically examining interrater reliability, temporal stability, and content validity. Findings are discussed with respect to both applications in managed care and psychometric research.
