Abstract
Aging is associated with significant changes in cognitive abilities, however, the lack of a suitable and short tool in Iran to measure the cognitive status of the elderly is evident. Therefore, this study was conducted with the aim of investigating the validity and reliability of the short questionnaire of the manual cognitive status of the elderly. The statistical population of this research included all elderly people over 65 years of age living in Arak city in 2019. From the statistical population of the research, 240 elderly people (128 men and 124 women) were selected by available sampling method. To collect data, Pfeiffer et al.'s short questionnaire of manual cognitive status of the elderly and Wechsler's memory form A were used. Descriptive statistics, confirmatory factor analysis using SPSS_26 and AMOS_24 software were used to analyze the data. The results of data analysis showed that the internal reliability according to Cronbach's alpha was 0.76. In order to check the validity of the questionnaire, confirmatory factor analysis and convergent validity were used, and the results of the confirmatory factor analysis indicate the desired validity of the questionnaire. Also, the Pearson correlation coefficient showed that there is a significant relationship between the cognitive status questionnaire and Wechsler memory subscales, and the Pearson correlation coefficient between the cognitive status score and the Wechsler total memory score was 0.71. The results showed that the questionnaire has a good reliability and validity coefficient. Therefore, it is suggested to use the questionnaire for clinical experts to diagnose the cognitive impairment of the elderly.
