Development and Initial Validation of the Adolescents’ Ageism Toward Older Adults Scale

Ageism toward older adults, prevalent in contemporary societies, seems to be internalized during childhood and consolidated during adolescence. Although several instruments have been developed to measure adolescents' ageism, they present a number of limitations. The study aimed at developing a new instrument, the Adolescents' Ageism Toward Older Adults Scale, and testing its psychometric properties.A three-phase process was followed: The instrument's items were developed empirically from focus groups of adolescents; its content validity was evaluated; and finally, its psychometric properties were tested through a multicenter cross-sectional study involving 575 adolescents.Exploratory factor analysis of the new scale retained 33 items grouped into 6 factors: moodiness, traditionalism, physical deterioration, antitechnologism, sageness, and sociability. Confirmatory factor analysis evidenced a second-order factor structure. Omega coefficients measuring internal consistency were above the cutoff of 0.60 for the 6 factors except for antitechnologism. Intraclass correlation coefficients for the entire scale and for the 6 factors were greater than 0.70, again excepting antitechnologism.The Adolescents' Ageism Toward Older Adults Scale is a promising measure of adolescents' negative and positive attitudes toward older adults. Its validation highlighted some criticalities that can be resolved by a few modifications. Further testing of the scale should be conducted after these modifications.
