Assessing Fruit and Vegetable Consumption in a 5 a Day Study Targeting Rural Blacks: The Issue of Portion Size. Journal of the American Dietetic Association, 96(10), 1040-2.
AbstractFood frequency questionnaires (FFQs) are used to collect dietary data in various study settings. Controversy exists regarding the relative contribution of portion information to FFQ sensitivity, validity, and reliability (1), (2), (3), (4), (5), (6), (7), (8). The application of FFQs to intervention studies requires investigation of whether portion information may contribute to the responsiveness of the instrument to dietary change
