Abstract
A questionnaire on consumption of a high-fat food item (chips) was completed by 288 subjects. This questionnaire was based in part on the Fishbein and Ajzen theory of reasoned action, but also included measures of habit and perceived behavioural control. In line with the theory of reasoned action, both the person's attitude and the subjective norm were found to be important predictors of reported consumption. Habit, but not perceived control, was also found to be an important predictor of intention and of behaviour. © 1992.
