Psychometric properties of the Persian version of the ambivalent ageism scale (benevolent and hostile) in the adult population in Iran.

BACKGROUND

With the growing population of older adults and the prevalence of negative attitudes towards them, the issue of ageism and its health and economic impacts in both benevolent and hostile contexts warrants special attention. It is crucial to examine the attitudes of other age groups towards older adults across different societies. Particularly, the benevolent dimension of ageism, which has been less explored in research, requires more focus. Therefore, this study aims to conduct a psychometric evaluation of The Ambivalent Ageism Scale among the adult population in Iran.

METHODS

This methodological study was conducted in comprehensive health centers in Gorgan city in 2023. A total of 381 eligible adults participated. The Ambivalent Ageism Scale (AAS) was utilized, and the psychometric assessment included translation, face validity, and content validity. Additionally, exploratory factor analysis and confirmatory factor analysis were performed. The reliability of the scale was evaluated using the internal consistency method. The research findings were analyzed using SPSS and AMOS software version 24.

RESULTS

Qualitative face and content validity assessments led to textual and editorial modifications of the items. The Content Validity Ratio (CVR), Item-Content Validity Index (I-CVI), and Kappa (K*) scores were acceptable for all items. In the exploratory factor analysis (EFA), similar to the original questionnaire, three factors were extracted, accounting for approximately 54% of the total variance. The fit indices in the confirmatory factor analysis (CFA) indicated an acceptable model fit. During CFA, four items were eliminated. The reliability of the entire questionnaire was deemed acceptable with a Cronbach's alpha coefficient of 0.763. Consequently, the Persian version of the Ambivalent Ageism Scale was confirmed with nine items.

CONCLUSION

The Persian version of The Ambivalent Ageism Scale demonstrates sufficient validity and reliability for measuring attitudes towards aging within Iranian society. Given the cultural adaptation of this tool, the questionnaire can be utilized to assess adults' views and attitudes towards older adults in both hostile and benevolent dimensions. Furthermore, it can aid in formulating family-oriented policies for older adult care and facilitate improvements in the quality of care for this population group.
