The authors studied the effectiveness of community-wide health education on physical activity knowledge, attitudes, self-efficacy, and behavior. Random samples of residents aged 18-74 years who lived in four central California cities (baseline, n=1,056 men and 1,183 women) were evaluated in 1979-1980 and approximately every 2 years thereafter to obtain four independent samples. Moreover, every subject in the initial independent samples was asked to retum for follow-up every 2 years thereafter ; subjects who completed all four examinations constituted the cohort sample (n=408 men and 499 women). Two medium-sized cities recelved health education and two similarly sized cities served as controls. Results indicated little consistent evidence of a treatment effect on physical activity knowledge, attitudes, or self-efficacy in either men or women. Among physical activity measures, there was an indication of a positive treatment effect for men in the independent samples for estimated daily energy expenditure and percent participation in vigorous activities (p
