Abstract

This study examined the effectiveness of computerized feedback on dietary cognitions and behaviors of 33 community college students (N = 33). Questionnaires that measure nutrition knowledge, self-efficacy, and dietary beliefs, as well as food consumption surveys, were administered to students pre- and post-intervention. On three occasions, every student utilized the Food Processor computer software as an intervention to input their personal menu from the previous 24-hour period, and every student received a computer-generated nutritional analysis of that menu. Personal beliefs regarding outcome expectations and self-efficacy are known to motivate one to set goals and initiate behavior, whereas self-regulation processes, which involve monitoring one’s practices and adapting strategies according to feedback, are important in maintaining behaviors. T-tests revealed a significant effect of computerized feedback on nutritional knowledge (t = 2.67, p < .05), self-efficacy (t = 3.13, p < .01), dietary beliefs (t = 2.36, p < .05), and food consumption (t = 2.05, p <.05). Hence, greater accuracy and constancy of feedback may impact personal cognitions, which may lead to dietary adjustments and maintenance of behavior.
