摘要

The current study used three decision making models to investigate how reasoned (i.e., logical) and reactive (i.e., impulsive) factors are related to healthy and unhealthy dietary decisions. A sample of 583 female students between 18 and 25 years of age completed measures on reasoned intentions and reactive willingness to eat healthy and unhealthy foods and eating behaviors. Participants also completed measures on reasoned factors about foods (attitudes, subjective norms, nutrition knowledge), reactive factors about foods (prototypes of eaters, affect), and dieting behaviors. Structural equation modeling (SEM) was used to examine how these factors predicted intentions and willingness to eat healthy foods (fruits and vegetables) and unhealthy foods (foods with added fats and sugars), and how intentions and willingness predicted consumption. Differences across dieters and nondieters were examined. Results suggested that attitudes and affect are related to intentions and willingness to consume healthy and unhealthy foods, whereas nutrition knowledge is related to intentions and willingness to eat only healthy foods. Intentions and willingness to eat foods were related to consumption of both healthy and unhealthy foods. Dieters had more positive prototypes of healthy eaters and more intentions to eat healthy foods than nondieters. Dieters also had more negative attitudes and affect about unhealthy foods, perceived fewer subjective norms to eat unhealthy foods, had more negative prototypes of unhealthy eaters, intended to eat fewer unhealthy foods, and consumed fewer unhealthy foods. Overall, these findings elucidate the importance of accounting for both reasoned and reactive factors in examining eating behaviors and the value of a comprehensive decision making model in explaining eating decisions for college students.
