The Aging Semantic Differential (ASD) scale needs revision as its original structure is not supported. A modified four-factor model showed the best fit for measuring attitudes toward older adults.

Area of Science:

  • Gerontology
  • Psychometrics
  • Social Psychology

Background:

  • The Aging Semantic Differential (ASD) is a 32-item scale measuring attitudes toward older adults.
  • Published over 20 years ago, its original three-factor structure lacks empirical support.
  • Previous factor analyses have failed to replicate the intended structure.

Purpose of the Study:

  • To evaluate the factor structure of the Aging Semantic Differential (ASD).
  • To identify the best-fitting factor model for measuring attitudes and stereotypes toward older people.

Main Methods:

  • Confirmatory factor analyses (CFA) were conducted.
  • 100 third-year medical students participated in the study.
  • Six different factor models from gerontological literature were compared.

Main Results:

  • The original three-factor structure of the ASD was not replicated.
  • A modified four-factor model, adapted from Holtzman, Beck, and Kerber (1979), demonstrated the best comparative fit.
  • Fit indices supported the modified four-factor structure as superior.

Conclusions:

  • The current structure of the Aging Semantic Differential (ASD) may not accurately capture attitudes toward older adults.
  • A revised four-factor model offers a potentially improved framework for assessing age-related bias and stereotypes.
  • Further validation of the modified ASD is recommended for reliable measurement in gerontological research.
