Examine effectiveness of a state's Youth Expanded Food and Nutrition Education Program (EFNEP) and assess the validity of the federal impact indicator method for reporting program outcomes.
A randomized, controlled field trial of 229 groups with 5,111 youth, 9-12 years old, in community settings.
6- to 8- hour, 7-lesson education experience with food preparation and tasting, an education experience typical of EFNEP in California.
US Department of Agriculture (USDA) impact indicators: nutrition knowledge, eating a variety of foods, food selection, and food preparation and safety practices.
Analysis of covariance model controlling for pretest, gender, age, and ethnicity, with group nested in condition.
Organizing responses by impact indicators, treatment participants made significant gains on the posttest compared to controls for 3 of 4 indicators (P < .008 to P < .0001). Gains were made by 34 to 68% of youth participants for 4 indicators. The impact indicator method for federal reporting compared favorably with results from a randomized controlled trial with groups nested in conditions.
This is the first report in the literature of (1) a large evaluation study of Youth EFNEP and (2) an estimate of the validity of the USDA impact indicator method for reporting program outcomes.
研究某州青少年拓展食品与营养教育计划（EFNEP）的有效性，并评估联邦影响指标法在报告项目成果方面的有效性。
在社区环境中对229个小组的5111名9至12岁青少年进行随机对照现场试验。
进行6至8小时、共7节课的教育体验，内容包括食物制备和品尝，这是加利福尼亚州EFNEP的典型教育体验。
美国农业部（USDA）影响指标：营养知识、食用多种食物、食物选择以及食物制备和安全实践。
采用协方差分析模型，控制前测、性别、年龄和种族，并将小组嵌套在条件中。
按照影响指标整理回答，与对照组相比，治疗组参与者在4项指标中的3项后测中取得了显著进步（P < .008至P < .0001）。4项指标中，34%至68%的青少年参与者取得了进步。联邦报告的影响指标法与将小组嵌套在条件中的随机对照试验结果相比表现良好。
这是文献中首次出现的关于（1）青少年EFNEP大型评估研究以及（2）对美国农业部影响指标法在报告项目成果方面有效性评估的报告。
