The authors investigated the effect of collecting food frequency intake data using questionnaires that record response intervals rather than exact frequencies of consumption. Measures of energy and 24 nutrients were calculated using both types of frequency data for subjects'mean intakes, rank classifications and group mean values. Frequency data obtained between 1987 and 1989 using the open-ended Health Habits and History Questionnaire (HHHQ) developed by Block and associates at the National Cancer Institute were recoded into the interval response formats used by the computer-scannable version of the HHHQ and into the format used in the food frequency questionnaire developed by Willett for the Nurses'Health Study and other studies. Compared with the open-ended HHHQ, for otherwise identical data sets, the closed-ended HHHQ and Willett response categories produced significantly different (p
