Measuring Awareness of Age-Related Change: Development of a 10-Item Short Form for Use in Large-Scale Surveys.

ABSTRACT: BACKGROUND AND OBJECTIVES:Existing measures of subjective aging have been useful in predicting developmental outcomes. Unlike other constructs of subjective aging, Awareness of Age-Related Change (AARC) focuses on how adults' self-perceptions of aging result in an awareness of age-related gains and losses. We developed a 10-item short form (SF) of the existing 50-item AARC questionnaire as a reliable, valid, and parsimonious solution for use primarily in large-scale surveys but also in applied contexts. RESEARCH DESIGN AND METHODS:AARC was assessed in a German and North American sample of 819 individuals. Item selection for the suggested AARC-10 SF was based on multidimensional item response theory (MIRT). Multi-group confirmatory factor analysis (CFA) was used to test for measurement inva
