Patient Impairment Lexicon: a validation study.

Growth of managed behavioral health organizations (MBHOs) has increased the need for a standardized diagnostic language. The Patient Impairment Lexicon (PIL; Goodman, Brown, & Deitz, 1992, 1996) is intended to address this need. Augmenting previous psychometric assessment (Klewicki, Bjorck, Leucht, & Goodman, 1998), the current study evaluated the PIL's construct validity. Sixteen raters completed impairment inventories; diagnoses based on the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised (DSM-III-R; American Psychiatric Association, 1987); and independent measures of psychiatric functioning for patients in 20 vignettes. Overall rater accuracy was significantly higher for PIL impairments than for diagnoses. As predicted, there were positive correlations between PIL impairments and psychiatric functioning for all 20 vignettes, 11 of which were significant. Results remained significant after controlling variance due to: (a) raters' past experience with similar patients and (b) vignette imaginability. Findings are discussed in terms of MBHO applications and future PIL research.

Patient Impairment Lexicon: a psychometric analysis.

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.

The effects of stressor type on projected coping.

Previous analog research (Bjorck & Cohen, 1993), in which Caucasian college students' projected coping responses to major stressors differed as a function of stressor type (threat, loss, or challenge), was replicated with an ethnoculturally diverse sample. Because Bjorck and Cohen's findings might have been confounded by participants' prior life experiences and/or differing perceptions of event controllability, these two dimensions were also assessed. Even after statistically controlling for these two potential confounds, however, projected coping again differed as a function of stressor type. Effects of both controllability and prior experience were also found. Results are discussed in terms of their application to coping processes in general and to coping with trauma in particular.
