Impact of work site health promotion on stages of dietary change : the Working Well Trial . The stages of change construct has been applied to healthful dietary behavior in cross-sectional studies . This report examines associations of stages of change with diet prospectively and addresses whether ( 1 ) baseline stage of change predicts participation , ( 2 ) forward changes in stage movement were greater in treatment work sites , and ( 3 ) change in stage was associated with adoption of healthful diets , using data from a cohort of 11,237 employees . Findings indicate that persons in later stages of change reported higher participation levels . Employees from intervention work sites who were in preaction stages at baseline were much more likely to shift into action and maintenance stages than controls . Changes in dietary stage of change were associated with decreases in fat intake and increases in fiber , fruit and vegetable intake . Net change in diet due to the intervention was modest . Stage of change appears to be useful for understanding mediators of health promotion intervention effectiveness .
