Debates about how to define successful aging have dominated gerontology for over 60 years. Regardless of how successful aging is conceptualized, in order to accurately understand how the construct changes over time and how it differs between people of varying ages, successful aging must be measured with instruments that are valid, reliable, and have measurement invariance. These analyses focus on subjective successful aging and examine the extent to which a reliable, valid, 3-item scale has measurement invariance across 12 years for individuals aged 50-86.
