The aim of this study was to develop a valid and reliable elder self-neglect scale (ESNS) for field research on Iranian community-dwelling older adults. This mixed-method exploratory study was conducted in three stages: (1) item generation using literature review, (2) item reduction by expert panels, and (3) assessing the psychometric properties. In the third stage, the face, content, and construct validity (exploratory factor analysis) were performed on the first sample (n = 450), and the final 26-item scale was developed. After that, confirmatory factor analysis and reliability were assessed on the second sample (n = 250). Data were analyzed using IBM-SPSS v.23 and AMOS v.24. Exploratory factor analysis identified six factors with a total variance of 77.53%. The goodness of fit was indicated by Structural Equation Modeling. The Cronbach's alpha was estimated at 0.85. The optimal cutoff point was 73. This scale with 26 items seems to be an effective tool in screening elder self-neglect.
