Abstract Background Social support is essential for individuals to cope with difficult circumstances. Older adults with disabilities face significant challenges in engaging with everyday activities. The current study examines the mediating role of perceived stress in the association between perceived social support and disability among Iranian community-dwelling older adults. Methods In this descriptive and cross-sectional study, 300 older adults were selected using cluster sampling from January to June 2022. The data were collected using the Multidimensional Scale of Perceived Social Support (MSPSS), the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2), and the Cohen Perceived Stress Scale-14 (PSS-14). The collected data was analyzed using structural equation modeling (SEM) in Mplus. Results The mean age of older adults was 68.71 ± 6.13 years, ranging from 60 to 85 years old. The results of this study revealed a significant relationship between perceived social support and disability (β=-0.20, SE = 0.06, p < 0.001) and perceived stress and disability (β = 0.50, SE = 0.05, p < 0.001). The results also confirmed the mediating role of perceived stress in the relationship between perceived social support and disability (β=-0.17, SE = 0.03, p < 0.001). Conclusion The results indicated that increasing social support could reduce disability by decreasing perceived stress. These results have important implications for policymakers and healthcare professionals in promoting healthy aging.
