The authors examined the role of social desirability in 445 participants’ responses to self-reported measures of ageism across two studies. In Study 1, college students and community adults completed the Relating to Older People Evaluation (ROPE) and a short form of the Marlowe–Crowne Social Desirability Scale (M-C SDS). Study 2 was a conceptual replication that included the Fraboni Scale of Ageism (FSA). Correlation analyses confirmed a small but significant relationship between scores on the positive ageist items and the social desirability scale in both studies. Ageist attitudes were correlated with negative ageist behaviors in Study 2. Implications for current views on ageism and strategies for reducing ageist attitudes and behaviors in everyday life are discussed.
