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.
我们开发并评估了一种针对青少年水果和蔬菜摄入量的简短测量方法。该测量方法可靠，且与3天食物记录数据显著相关。正确分类率（63%）和特异性（63%）良好。敏感性（33%）较低。尽管仍需要改进分类方法，但该测量方法值得推荐。
