In longitudinal studies, parents are the most accurate source of information on young children's dietary intake; for older children, questioning children themselves may be more appropriate. However, if parental reports for young children and self-reports of older children are to be used in the same analyses, the measures must be comparable.
During school hours, fourth and sixth graders in 14 Flemish (Belgium) primary schools completed an online 15-item food frequency questionnaire with a retest questionnaire one to two weeks later; parents completed a paper-and-pencil or online questionnaire. Test-retest data were available for 286 children; children's tests could be matched to parents' reports for 275 children.
On average, test-retest correlations were 0.68 (grade 4: 0.63; grade 6: 0.71) and correlations between children's and parents' reports were 0.44 (grade 4: 0.39; grade 6: 0.49). No systematic differences were found between the test and retest. Comparison of children's and parents' reports resulted in significant differences for six of the 15 items.
Low consensus between parents' and children's reports for several items may impede comparisons at a group level. Additionally, the results indicate more optimal dietary assessment in sixth graders.
在纵向研究中，父母是幼儿饮食摄入量最准确的信息来源；对于年龄较大的儿童，询问儿童本人可能更合适。然而，如果要在同一分析中使用幼儿的父母报告和年龄较大儿童的自我报告，这些测量方法必须具有可比性。
在上课时间，比利时弗拉芒地区14所小学的四年级和六年级学生完成了一份15项的在线食物频率问卷，并在一到两周后完成了一份重测问卷；家长们完成了一份纸质或在线问卷。有286名儿童的重测数据；275名儿童的测试结果可以与家长的报告相匹配。
平均而言，重测相关性为0.68（四年级：0.63；六年级：0.71），儿童报告与家长报告之间的相关性为0.44（四年级：0.39；六年级：0.49）。测试和重测之间未发现系统差异。儿童报告与家长报告的比较导致15项中的6项存在显著差异。
家长报告与儿童报告在几个项目上的低一致性可能会妨碍在群体层面上的比较。此外，结果表明六年级学生的饮食评估更为理想。
