The Community Aging in Place-Advancing Better Living for Elders (CAPABLE) program reduces disability in low-income older adults. In this study, we used CAPABLE baseline and 5-month data to examine whether its effects in reducing activities of daily living (ADLs) and instrumental ADLs (IADLs) difficulties differed by participants' financial strain status. At baseline, participants with financial strain were more likely to report higher scores on depression (p < .001), have low energy (p < .001), and usually feel tired (p = .004) compared with participants without financial strain, but did not differ in ADL/IADL scores. Participants with financial strain benefited from the program in reducing ADL (relative risk [RR]: 0.61, 95% confidence interval [CI]: 0.43, 0.86) and IADL disabilities (RR: 0.69, 95% CI: 0.54, 0.87), compared with those with financial strain receiving attention control. Individuals with financial strain benefited more from a home-based intervention on measures of disability than those without financial strain. Interventions that improve disability may be beneficial for financially strained older adults.
