Abstract
Social support (SS) was investigated as a predictor of quality of life (QoL) and a moderator and mediator in the relationship between stressful life events (SLE) and QoL in persons living with HIV/AIDS (PLWHA). Data were obtained from 809 PLWHA in the course of interviews using standardized questionnaires. Multiple regression analysis indicated SS accounted for 24% of the variance in QoL, R2 = .2447, p < .0001. Results from generalized estimating equations analysis proved significant and SS, χ2 = 96.21, p < .0001, number of SLE, χ2 = 55.16, p < .0001, and intensity of SLE, χ2 = 56.27, p < .0001, were found to predict QoL. The Sobel test results revealed SS to have a partial mediating effect, Sobel's z = −3.625, p < .0003. The results suggest SS represents a key variable to consider when planning care strategies aimed at optimizing the QoL of PLWHA.
