Also, the reliability was assessed through through its internal consistency (Cronbach’s alpha and McDonald’s omega), composite reliability (CR), and maximal reliability (MaxR). The data compiled online was based on a sample of 400 older adults aged above 65 years. Results: The results of the study indicate that the Persian version of this scale comprises three factors with 11 items (Factor 1: Physical Health; Factor 2: Mental Health; Factor 3: Cognitive Function) that explaining 65.764% of the total variance.
