Abstract

Background: Low-income African American men are disproportionately burdened with disease and mortality and are least likely to consume healthy diet. One such dietary behavior is intake of five or more cups of fruits and vegetables per day. There is a need for the development of health educational interventions that target African American men with regard to this behavior. As a prerequisite for such intervention research, theory-based instruments need to be developed. A new fourth-generation theory is multi theory model (MTM) of health behavior change. Therefore, the purpose of this study was to determine the validity and reliability of an instrument based on MTM for behavioral change of fruits and vegetables consumption in African American men and propose an intervention for changing this behavior. Methods: An instrument utilizing MTM initiation constructs of participatory dialogue, behavioral confidence, changes in physical environment, and MTM sustenance constructs: emotional transformation, practice for change, and changes in the social environment was developed. Internal consistency reliability was tested using Cronbach’s alpha and construct validity was tested using confirmatory factor analysis (CFA) through maximum likelihood method (n=134). Results: The entire scale and all construct subscales were found to be reliable at the accepted 0.70 a priori level. The maximum likelihood method of CFA confirmed the presence of one factor for all subscales and had an Eigenvalue >1, and all factors loadings were >0.40. Conclusions: The scale developed in this study can be used for designing and evaluating interventions that promote fruits and vegetables consumption among African American men.
