Reliability and Validity Issues for Two Common Measures of Medical Students' Attitudes toward Older Adults

Abstract

Results are reported from 2 common measures of medical student attitudes toward older adults: Maxwell-Sullivan Attitude Survey (MSAS); and UCLA Geriatrics Attitude Survey (GAS), with students entering the University of South Carolina School of Medicine (USCSM) in the period 2000–2005. A reliability analysis incorporating item means, Cronbach's alpha, item correlation matrix, and, Spearman-Brown prediction for positively and negatively worded items was conducted. Internal consistency results were unacceptable, revealing reliability and validity problems in this sample of medical students. Reconsideration of the use of these common measures, and a reframing of attitudes of medical students toward older adults seem appropriate.
