Abstract: This paper developed the prescriptive ageism scale (AIC) of contemporary Chinese college students against the elderly, analyzed the items and tested its reliability and validity. Initial items were collected and screened in the form of online interviews to form the original questionnaire, and the final scale was formed by the data-driven method of exploratory and confirmatory factor analysis. Finally, a total of 13 questions in 3 dimensions of active inheritance, identity invasion and passive consumption were explored. There was an appropriate correlation between each dimension and the total score (0.567, 0.793, 0.871). The fitting index of the three-factor model was positive. The overall Cronbach's alpha coefficient of the scale was 0.835, and the Guttman half-factor coefficient was 0.811. The correlation validity of C-FSA and SIC scales were 0.615 and 0.809, respectively. The prescriptive ageism scale for Chinese college students compiled according to the actual situation of contemporary Chinese college students' prescriptive stereotypes of the elderly has a good reliability and validity test, and has the reliability of theoretical data and the feasibility of practical application.
