In an African American community, older age, hypertension, and diabetes were associated with a higher 'powerful others' locus of control, highlighting the potential role of faith-based and physician-led interventions for cardiovascular risk reduction.
Marcus Plescia (2004) conducted a cross-sectional in Cardiovascular disease and diabetes risk factors (n=447). Cardiovascular disease and diabetes risk factors vs. Respondents without risk factors was evaluated on Powerful others locus of control score (hypertension vs no hypertension) (p=<0.0001). In a survey of an African American community, respondents with hypertension, diabetes, or age over 65 had significantly higher scores for powerful others locus of control, suggesting a strong influence of external figures like physicians and ministers on health behaviors.
