Abstract
Successful aging is a multifaceted concept that encompasses physical, cognitive, and social dimensions, and can have significant effects on the physical and mental health of older adults. Given the lack of a suitable concise tool in Iran to measure successful aging, this study aimed to investigate the validity and reliability of the Persian version of the Successful Aging Questionnaire.
This descriptive cross-sectional study was conducted. The study population included all older adults in Kermanshah Province, with 350 participants selected based on inclusion criteria through convenience sampling. Participants responded to the Successful Aging Questionnaire by Reker (2009) and Zangari et al.'s (2019) Successful Aging Scale. Data analysis was performed using descriptive statistics and confirmatory factor analysis in SPSS-24 and Amos-24.
In the present study, the average age of participants was 64.54±6.23 years. The number of male respondents was 176 (47%) and female respondents was 156 (53%). The internal reliability, based on Cronbach's alpha, for the subscales of Healthy Lifestyle, Adaptive Coping, and Engagement with Life were 0.712, 0.676, and 0.812, respectively. Confirmatory factor analysis and concurrent validity were used to assess the validity of the questionnaire. The results of the confirmatory factor analysis showed that the model fitted well with the data for predicting the three factors (subscales) of the questionnaire. Pearson's correlation coefficient results indicated a significant and direct correlation between the subscale scores of Reker's Successful Aging Questionnaire and Zangari et al.'s Successful Aging Scale.
The Persian version of the Successful Aging Questionnaire has demonstrated good validity and reliability among individuals aged 60 and above. Given the suitable psychometric properties and the small number of questions, the application of this questionnaire in future studies and the exploration of the relationship between successful aging and other important variables can open new avenues in the field of aging studies in Iran.
