Abstract
Health Self-Empowerment Theory asserts that 5 controllable psychological variables predict engagement in health-promoting behaviors. This study tests the theoretical integrity of Health Self-Empowerment Theory and its usefulness in predicting health-promoting behaviors and body mass index. Results from surveying 189 predominantly low-income, overweight/obese, and culturally diverse adults showed that most Health Self-Empowerment Theory variables were positively correlated. Structural equation modeling showed that 4 variables significantly predicted engagement in health-promoting behaviors, which mediated the relationships between body mass index and (a) motivation, (b) health self-efficacy, and (c) self-praise. Results support creating psychologically informed interventions to increase engagement in health-promoting behaviors and decrease body mass index among low-income adults, particularly racial/ethnic minorities, at risk for obesity-related health problems.
