旨在改变幼儿饮食和身体活动行为的干预措施需要精确和准确的测量工具。作为一个更大的社区项目的一部分，我们制定了三份基于学校的调查问卷，以评估（a）水果和蔬菜的摄入量，（b）身体活动和电视观看情况，以及（c）感知到的家长对饮食和身体活动的支持。对所有问卷进行了重测信度，并测量了水果和蔬菜摄入量、体力活动和电视观看的有效性。对 84 名学童（8.3 +/- 1.1 岁）进行了研究。通过两次间隔 1 至 2 小时的问卷调查来评估重测可靠性。水果和蔬菜问卷的有效性通过直接观察来衡量，而体力活动和电视问卷的有效性则通过家长电话访谈来验证。所有三份问卷均取得了出色的重测信度（P
Interventions aiming to modify the dietary and physical activity behaviors of young children require precise and accurate measurement tools. As part of a larger community-based project, three school-based questionnaires were developed to assess (a) fruit and vegetable intake, (b) physical activity and television (TV) viewing, and (c) perceived parental support for diet and physical activity. Test-retest reliability was performed on all questionnaires and validity was measured for fruit and vegetable intake, physical activity, and TV viewing. Eighty-four school children (8.3 +/- 1.1 years) were studied. Test-retest reliability was performed by administering questionnaires twice, 1 to 2 hours apart. Validity of the fruit and vegetable questionnaire was measured by direct observation, while the physical activity and TV questionnaire was validated by a parent phone interview. All three questionnaires yielded excellent test-retest reliability (P
