Physical and psychosocial functioning in multiple sclerosis: descriptions, correlations, and a tentative typology.

Multiple sclerosis (MS) is a disease of great variety and ambiguity. It outcome is both multidimensional and uncertain. As part of an ongoing effort to describe and differentiate the various courses that MS can follow, 81 out-patients diagnosed with MS completed the California Psychological Inventory (CPI) and the Sickness Impact Profile (SIP) administered as a structured interview. Descriptive statistics for the SIP and the CPI are provided and examined as a function of age and sex. Correlations between health status and personality scales are reported. Increasing physical dysfunction is associated with lowered performance on a broad array of psychosocial dimensions but only among women. A cluster analysis of CPI factor scores is described and a very tentative typology of persons with MS is offered for further investigation.
