Abstract

The purpose of this study was to determine the correlation of perceived stress with selected physiological and psychological factors in an HIV-infected, predominantly African American population and to assess the multivariable effects on perceived stress. The variables that correlated significantly with perceived stress were entered into a backward stepwise regression model. Pearson's r analysis showed significant correlations between perceived stress and state and trait anxiety, depression, HIV-related symptoms, sleep quality, daytime sleepiness and fatigue. State and trait anxiety, depression and fatigue retained significance (p<0.1) in the final regression model. These factors explained approximately 80% of the variance in perceived stress. The significant interactions of multiple physiological and psychological correlates suggest that perceived stress is a complex outcome with a multifactorial etiology. Further, the model suggests that psychological factors may contribute to perceived stress in this population more than physiological factors such as HIV-related symptomatology or stage of disease.
