This study compared fruit and vegetable assessments derived from 4 self-administered questionnaires.
Among 102 adolescents, servings of fruits and vegetables assessed by 4 questionnaires were compared with estimates from 24-hour recalls.
The prevalence of consuming 5 or more servings of fruits and vegetables a day was underestimated by the questionnaires.
Questionnaires asking subjects to recall their diet over the previous year were more effective in ranking subjects (r's=. 42) than those assessing previous-day diet'r's=. 30).
Brief assessments of fruit and vegetable intake are more useful for ranking subjects than for estimating prevalence of consumption of 5 or more servings per day.
