Background: By 2015, 50% of all HIV/AIDS cases in the United States will be in persons 50-plus years of age. Very little, if any, research has examined resilience in older HIV-infected persons. This research investigated the mediating effect of resilience between HIV-related stress and health-related quality of life (HRQoL) in PLWHA over fifty. Methods: Data from a sample of 303 PLWHA over 50 was analyzed using structural equation modeling (SEM) to define a hypothesized resilience measure (represented by self-efficacy, coping, hope/optimism and social support) and to test a meditating effect of resilience between HIV-related stress and HRQoL (physical well-being, function and global well-being, and emotional well-being). Results: The SEM results showed satisfactory model fit for resilience construct, χ2 (14, N=301) =14.9, p=0.387, and CFI=0.99, IFI=0.99, TLI=0.99, RMSEA=0.014 (95% CI: 0.000, 0.059), with all factor loading raging from 0.60 to 0.80. The meditational model with an adequate fit (χ2 (63, N=301) =164.273, p<0.0001, CFI=0.95, IFI=0.95, TLI=0.93, RMSEA=0.073 (95% CI: 0.060, 0.087)) revealed a partial mediating effect of resilience between HIV-related stress and HRQoL. Conclusion: The model indicated a well-defined resilience construct and suggested that HIV-related stress partially reduces the negative influence of HIV-related stress on HRQoL. Future design of interventions that build personal capacity and environmental support may contribute to better management of HIV/AIDS and may be more efficacious in increasing HRQoL in older PLWHA.
