Expanding the Health Action and Process Approach to Predict Physical Activity in African Americans With HIV/AIDS: A Hierarchical Regression Analysis

The current study investigated an expanded Health Action and Process Approach (HAPA) as a health-promotion model of physical activity/exercise behavior for African Americans living with HIV/AIDS. Predictions of physical activity/exercise participation were investigated among 110 African Americans living with HIV/AIDS. Results indicate the expanded HAPA model accounts for 35% of the variance in physical activity/exercise participation. The most significant predictor variables were symptom severity, outcome expectancy, and action and coping planning. Action and coping planning also partially mediated the relationship between physical activity/exercise intention and behavior. Results of the study provide partial support for the use of this expanded HAPA model in the design and implementation of health-promotion behavioral interventions targeting physical activity/exercise for Africana Americans with HIV/AIDS.
