Comparison of the Medical Outcomes Study Short-Form 36-Item Health Survey in black patients and white patients with acute chest pain.
Few data are available regarding the performance of the Medical Outcomes Study (MOS) Short-Form 36-Item Health Survey (SF-36) in black patients. In this article, the reliability and validity of the MOS SF-36 is compared in a population of black patients and white patients with acute chest pain. The MOS SF-36 was administered to 1,160 patients (31% black) who presented to the emergency department of an urban teaching hospital with acute chest pain from October 1990 to May 1992. In unadjusted analyses, black patients had significantly lower scores compared with white patients for several dimensions of the SF-36. Correlations among the eight subscales were similar, and the internal consistency of each of the eight subscales was excellent for both groups (Cronbach's coefficient alpha range .64 to .93). Each subscale had similar clinical and nonclinical correlates in black patients and white patients. In multivariate models, race was not a significant independent correlate of any of the eight subscales. Thus, the MOS SF-36 had similar reliability and validity in this population of black patients and white patients with acute chest pain who presented to an urban teaching hospital. If these findings are confirmed in other populations, they suggest that results from the MOS SF-36 may be interpreted similarly in black patients and white patients, after adjusting for clinical and sociodemographic data. Whether these findings are generalizable to other conditions and less acute settings requires further investigation.
