Abstract
Abstract
We developed and evaluated a brief measure of fruit and vegetable consumption for adolescents. The measure was reliable and significantly correlated with 3-day food record data. Correct classification rate (63%) and specificity (63%) were good. Sensitivity (33%) was lower. The measure is recommended, although improvements in classification are still needed.
