Overview

Confirmatory factor analysis improved reliability and predictive power of ageism measure in older adults, suggesting its efficacy.

Key Points

  • To evaluate the reliability and validity of the Everyday Ageism Scale using item response theory and confirmatory factor analysis.
  • Conducted confirmatory factor analysis and item response theory analysis.
  • Used data from 486 older adults in North America.
  • Evaluated item-level properties and measurement precision of the scale.
  • Everyday Ageism Scale showed acceptable reliability with McDonald’s omega coefficients.
  • Confirmed structural validity with a three-factor model.
  • Identified items needing refinement for better predictive power.
