Аннотация:This study examined the impact of moral norms, self‐identity, and past behavior on intention to buy organic tomatoes and organic tomato sauce, using the theory of planned behavior (TPB). The questionnaire, which included measures of attitudes, subjective norm, perceived behavioral control, moral norms, past behavior, and self‐identity was completed by approximately 500 people for each food. Multiple regressions showed that for both foods, moral norms and self‐identity added significantly to the prediction of intention over and above the other variables, even when the effect of past behavior was included. There was some evidence of past behavior moderating the self‐identity/intention relationship for processed organic tomato sauce, but not for fresh organic tomatoes. Implications of the findings are discussed.
