Assessment of the Refined Aging Semantic Differential: Recommendations for Enhancing Validity

The Aging Semantic Differential (ASD) by Rosencranz and McNevin (1969 Rosencranz, H. and McNevin, T. 1969. A factor analysis of attitudes toward the aged. Gerontologist, 9: 55–59. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) is the most widely used instrument in gerontological and geriatric education to assess the stereotypic attitudes young people have toward older adults. Polizzi (2003 Polizzi, K. 2003. Assessing attitudes toward the elderly: Polizzi's refined version of the Aging Semantic Differential. Educational Gerontology, 29: 197–216. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) updated the ASD with current adjectives and reduced the instrument to a single latent factor, attitude. We examine the validity of this major instrument and describe the strengths and shortcomings. The instrument was administered to 199 medical students that participated in a national pilot project, Vital Visionaries, funded by National Institute on Aging. Confirmatory factory analysis using structural equation modeling (SEM) was used. Qualitative data captured stereotypic attitudes young people have toward older adults. SEM indexes suggest that a one-factor structure has poor fit. Qualitative analyses suggest medical students hold multiple dimensions of stereotypic attitudes toward older adults. We suggest that the latent factor, attitude, can be assessed with fewer observed items, thereby creating room for the additional latent factors. The resulting instrument could be just as short, but offer a more comprehensive assessment of young people's stereotypic attitudes toward older adults.
