Valid and reliable non-objective assessments of guardian and preschool personnel reports are necessary when estimating young children's health behaviors. This study examines the test-retest reproducibility of (a) guardian and preschool personnel questionnaires about correlates of preschool-aged children's energy balance-related behaviors (EBRBs), (b) a screen time diary, and (c) a food frequency questionnaire (FFQ) reported by a guardian. A sample of guardians having preschool-aged children ( = 69) and preschool personnel ( = 61) completed questionnaires twice within a five-week time interval during April⁻May 2018 in Finland. Intra-class correlations (ICC), kappas, and percentage agreement were calculated to test the test-retest-reproducibility. The guardian questionnaire for correlates of the children's EBRBs demonstrated mainly moderate to good reproducibility whereas the preschool personnel questionnaire of preschool correlates for children's EBRBs was mostly good. The reproducibility of the screen time diary was good and FFQ food items showed mostly moderate reproducibility. The reproducibility of the FFQ foods items for vegetables, fruit, and berries was slightly better for the amount consumed than for the frequency of consumption. To conclude, all the instruments are acceptable for use in future studies.
在评估幼儿的健康行为时，对监护人及学前教育工作人员报告进行有效且可靠的主观评估是必要的。本研究考察了以下内容的重测信度：(a) 监护人和学前教育工作人员关于学龄前儿童能量平衡相关行为（EBRB）相关因素的问卷；(b) 屏幕使用时间日记；以及 (c) 监护人报告的食物频率问卷（FFQ）。2018年4月至5月期间，在芬兰，一个由有学龄前儿童的监护人（n = 69）和学前教育工作人员（n = 61）组成的样本在五周时间间隔内两次填写问卷。计算组内相关系数（ICC）、卡帕值和百分比一致性以检验重测信度。关于儿童EBRB相关因素的监护人问卷显示出主要为中等至良好的信度，而学前教育工作人员关于儿童EBRB学前相关因素的问卷大多具有良好信度。屏幕使用时间日记的信度良好，FFQ食物项目大多显示出中等信度。FFQ中蔬菜、水果和浆果的食物项目在摄入量方面的信度略高于消费频率方面。总之，所有这些工具在未来研究中均可接受使用。
