Background & aims. Elderly people have different issues at the end of their lives. This study was conducted to analyze the psychometric properties of the Persian version of Attitudes of Older People to End of Life Issues (AEOLI) questionnaire. Methods. 189 elderly people participated in this descriptive study. Face, content and construct validity and reliability were assessed for determining the psychometric characteristics of the questionnaire. Construct validity was determined by exploratory factor analysis using principal component analysis with varimax rotation. Results. The results of this study indicate that the questionnaire has an appropriate face and content validity. Internal consistency (Cronbach’s alpha = 0.78, ICC = 0.729) showed a good reliability for the questionnaire. Factor analysis showed the nine items of the questionnaire can measure the attitude of the elderly toward end-of-life issues. Conclusions. The findings of this study showed that the Persian version of the 27-item questionnaire of the elderly attitude toward end-life issues has good validity and reliability.
