Although poor dietary habits have a great effect on the health status of children, especially in toddlers, a few questionnaires exist for the assessment of dietary imbalances. This study aims to assess the validity and reliability of the NutriCHEQ in Iranian healthy toddlers.
In this cross-sectional study, first, the NutriCHEQ was translated to Persian and culturally adapted by the forward-backward translation technique. In order to assess the face validity, we used a cognitive interviewing technique of 25 parents/caretakers of healthy toddlers. In the next step, experts assessed content validity, respectively. One item was removed during the content validity process. Then, a blueprint of NutriCHEQ was distributed among 156 parents/caretakers of healthy toddlers in different focal points in Tehran for assessing construct validity by nonlinear principal components analysis. In addition, the anthropometric indices checklist and Food Frequency Questionnaire (FFQ) were filled out for toddlers. Then, construct validity was assessed. The Varimax rotation ran for two sections separately. The four-factor structure was confirmed.
The model showed a good fit, and all the extracted variance of four factors were satisfactory (F1 = 20.77; F2 = 22.30; F3 = 14.75; and F4 = 13.71). All of the extracted items of the NutriCHEQ in two parts showed 71.53% cumulative variance. For criterion-related validity, there was a statistically significant positive correlation between the NutriCHEQ and Z-score (rho = 0.632, < 0.001). The Bland-Altman result indicates 95% limits of agreement between the NutriCHEQ questionnaire and Z-score.
Therefore, we concluded that NutriCHEQ is a valid, reliable, and convenient instrument to identify the Iranian toddlers' nutritional status. Therefore, it can be used for research and clinical settings.
尽管不良饮食习惯对儿童的健康状况有很大影响，尤其是对幼儿，但用于评估饮食不均衡的问卷较少。本研究旨在评估NutriCHEQ在伊朗健康幼儿中的有效性和可靠性。
在这项横断面研究中，首先，NutriCHEQ通过前后翻译技术被翻译成波斯语并进行文化调适。为了评估表面效度，我们对25名健康幼儿的父母/照料者采用了认知访谈技术。下一步，专家分别评估内容效度。在内容效度过程中删除了一项。然后，NutriCHEQ的蓝图分发给德黑兰不同地点的156名健康幼儿的父母/照料者，通过非线性主成分分析评估结构效度。此外，还为幼儿填写了人体测量指标清单和食物频率问卷（FFQ）。然后，评估结构效度。Varimax旋转分别对两个部分进行。确认了四因素结构。
模型显示拟合良好，四个因素的所有提取方差均令人满意（F1 = 20.77；F2 = 22.30；F3 = 14.75；F4 = 13.71）。NutriCHEQ两部分中所有提取的项目显示累积方差为71.53%。对于效标关联效度，NutriCHEQ与Z分数之间存在统计学上显著的正相关（rho = 0.632，<0.001）。Bland-Altman结果表明NutriCHEQ问卷与Z分数之间的一致性界限为95%。
因此，我们得出结论，NutriCHEQ是一种有效、可靠且方便的工具，可用于识别伊朗幼儿的营养状况。因此，它可用于研究和临床环境。
