Understanding problems of promoting health and success in the elderly become more important concerning life expectancy increase in people with physical disabilities. This study aimed to determine social factors of successful aging in the elderly with physical disabilities supported by charitable associations.

This is a cross-sectional study, which was carried out on 153 elderlies with physical disabilities aged 55 years and older in Tehran from 2021 to 2022. The subjects were selected using the convenience sampling method. Data were collected through a demographic information checklist, successful aging questionnaire, sense of social justice, social network, and socio-economic base. Data were analyzed using Pearson correlation tests, analysis of variance, and generalized linear regression.

The average age of the subjects was 64.27±8.4, and 56.9% were male. The generalized linear regression model showed a significant relationship between the demographic variables and the education level with successful aging (p<0.05). The relationship between the main dependent variables and successful aging was investigated using adjusting the effect of demographic variables. There was a significant relationship between the socioeconomic base with successful aging (B>0.178; p=0.001). However, there was no significant relationship between successful aging with social justice sense (p>0.05). There was a significant relationship between successful aging with different dimensions of social network (p<0.05), except for the intimacy dimension.

The results of this study can be helpful for policymakers, planners, and social workers to social rehabilitate the elderly with disabilities and design interventions.
