Survey was performed to assess construct validity, criterion validity, and reliability (Internal consistency and test-retest reliability) using a sample of 300 elderly persons living in community.
Results: We measured content validity using content validity index (CVI) and final 46 items were chosen. Factor analysis was performed to assess construct validity and criterion validity was assessed by measuring correlations with REALM scores.
