斯坦福大学五城项目(见Farquhar，Fortmann，Maccoby，&Haskell，1985)的三个横截面数据波(N=2,055；2,026和2,068)和两个纵向数据波(N=1,384和1,151)被分析以确定饮食自我效能感是否中介了饮食知识和行为之间的关系。在横截面数据波中，自我效能感高(与低)的人之间的知识-行为相关性更大。在纵向数据波中，自我效能感提高者的知识行为相关性增强，自我效能感降低者的知识行为相关性降低。对旨在改善个人健康行为的公共卫生运动提出了建议。
Three cross-sectional data waves spanning 10 years (N= 2,055; 2,026; and 2,068) and 2 longitudinal data waves spanning 4 years (N= 1,384 and 1,151) from the Stanford Five-City Project (see Farquhar, Fortmann, Maccoby, & Haskell, 1985, for a full description of the project) were analyzed to determine whether diet self-efficacy mediated the relation between diet knowledge and behavior. In the cross-sectional data waves, knowledge-behavior correlations were greater among those with high (compared to low) self-efficacy. In the longitudinal data waves, knowledge behavior correlations increased among those who increased their self-efficacy and decreased among those who decreased their self-efficacy. Recommendations are made for public health campaigns designed to improve individuals' health behaviors.
