Abstract
Locus of control is a concept defined based on social learning theory, and focuses on individuals' beliefs regarding factors that influence their health status. Health Locus of Control (HLC) and its relationship with Quality of Life (QOL) in HIV positive patients in local population were studied. This was a cross-sectional study on 80 HIV-positive patients. Multidimensional Health Locus of Control (MHLC) Scale and Medical Outcome Study Short-Form Health Survey (MOS-SF-36) used to measure patients' HLC and QOL, respectively. Internal, external, and chance HLC mean ± SD scores were 30.31±3.87, 24.17±5.03, and 32.01±4.49, respectively. Positive correlation was found between internal HLC scores and both physical (p <0.001, r = 0.53) and mental quality of life (p <0.001, r = 0.48). Multiple regression analysis showed that internal HLC was the only significant predictor of quality of life. HIV-positive patients who believe their health is mostly influenced by individual's actions and behaviors (internal HLC) showed a higher quality of life. These findings suggest that modifying health locus of control beliefs, hypothetically could influence patients' quality of life.
