Özet

Awareness of age-related change (AARC) is a multidimensional concept that evaluates the experiences of aging. Accordingly, this study aimed to adapt the long (AARC-50) and short (AARC-10) forms of the AARC scale for the Turkish population and evaluate their psychometric testing. This study included 570 individuals aged 40–92 years. The data of this study were obtained online by the snowball method. Data for this study were collected using the personal information form, AARC scale, and SF-12 quality of life scale. The form was translated and back-translated, expert opinions were obtained, and criterion-related validity, factor, test–retest, and reliability coefficient analyses were performed. Notably, the Cronbach’s alpha values of the two-factor 50- and 10-item scales were 0.923 and 0.717, respectively. The correlation of AARC with SF-12 varies between 0.035 and 0.528. In addition, the test–retest reliability score and content validity index were 0.90. Regarding the results of the factor analyses for the long and short forms, the long form demonstrated good results in terms of the chi-square divided by degrees of freedom and root mean square error of approximation, whereas the short form demonstrated good results in terms of goodness (comparative, normal, and adjustment goodness-of-fit index) and standardized root mean square residual. This study found that the AARC-50 and AARC-10 scales are valid and reliable tools for evaluation in the Turkish population. In the future studies, researchers can choose the appropriate form based on the conditions of their studies.
