Development and Validation of a Revised Ambivalent Ageism Scale for Use in the Health Care Sector: The AAShc

Abstract Background and Objectives The aim of this study was to adapt and validate the Ambivalent Ageism Scale (AAS) among paramedical students for use in the health care sector. Research Design and Methods A cross-sectional study was conducted among the following paramedical students: physiotherapy, occupational therapy, and nursing students. A total of 6 items were added based on the literature and the scale was evaluated by students and professors with experience working with older adults. The following psychometric properties were evaluated: internal consistency, concurrent validity, structural validity (exploratory factor analysis), and reliability. Results A total of 265 students participated: 19.2% physiotherapy students, 27.5% occupational therapy students, 50.6% nursing students, and 2.6% other paramedical students. The concurrent validity study showed a significant correlation between AAShc (Ambivalent Ageism Scale in the health care sector) and UCLA-GAS-F (French version of the University of California, Los Angeles Geriatric Attitudes Scale) with r (265) = 0.491 (p < .001). The factor analyses produced an 18-item (α = 0.866) scale composed of 5 factors: Infantilization (5 items, α = 0.766), Control (2 items, α = 0.789), Overaccommodation (2 items, α = 0.829), Unwanted help (2 items, α = 0.656), and Hostile Ageism (7 items, α = 0.717). Finally, the generalizability analysis revealed a G-coefficient of 0.86, a Phi-coefficient of 0.83, and a standard error of measurement of 2.31%. Discussion and Implications The AAShc appears to be a valid and reliable scale to measure ageism among paramedical students. This scale can be a useful tool to reduce ageism toward older adults in the health care sector.
