Unpacking atitudes towards genetically modified food.

The present study investigates the structure of attitudes towards genetically modified (GM) food. A total of 431 respondents completed a questionnaire measuring their overall attitude, cognition and affect towards GM food. A model with distinct positive and negative, affective and cognitive components and a separate factor for perceived risk and worry best accounted for the data. Negative - but not positive - components directly affected behavioural intentions. Implications of these findings for our understanding of attitudes towards GM food and their impact on behaviour are discussed.
