The Pediatric Eating Assessment Tool (PediEAT) is a parent-report instrument developed to assess symptoms of feeding problems in children aged 6 months to 7 years. The purpose of this study was to identify the factor structure of the PediEAT and test its psychometric properties, including internal consistency reliability, temporal stability, and construct validity.
Participants included 567 parents of children aged 6 months to 7 years. Fifty-four percent of the sample had parent report of a diagnosed feeding problem or feeding concerns. Exploratory factor-analysis techniques were used to remove redundant or non-endorsed items and identify the factor structure of the instrument. Construct validity was examined with 466 parents completing the Mealtime Behavior Questionnaire as a criterion standard. Known-groups validation was used to compare PediEAT scores between children with and without diagnosed feeding problems. Temporal stability of the PediEAT was examined with 97 parents repeating the PediEAT after 2 weeks.
Principal components factor analysis with varimax rotation supported a 4-factor model accounting for 39.4% of the total variance. The 4 subscales (Physiologic Symptoms, Problematic Mealtime Behaviors, Selective/Restrictive Eating, Oral Processing) demonstrated acceptable internal consistencies (coefficient alphas: 0.92, 0.91, 0.83, 0.83; respectively). Construct validity was supported in 2 ways. The PediEAT correlated with the Mealtime Behavior Questionnaire (r = 0.77, P < 0.001) and total score and subscale scores were significantly different between children with and without diagnosed feeding problem (P < 0.001). Temporal stability was demonstrated through test-retest reliability (r = 0.95, P < 0.001).
Strong psychometric properties support the use of the PediEAT in research and clinical practice.
儿童饮食评估工具(PediEAT)是一种由家长报告的工具,用于评估6个月至7岁儿童的喂养问题症状。本研究的目的是确定PediEAT的因子结构,并测试其心理测量特性,包括内部一致性信度、时间稳定性和结构效度。
参与者包括567名6个月至7岁儿童的家长。样本中有54%的家长报告孩子被诊断有喂养问题或存在喂养方面的担忧。采用探索性因子分析技术去除冗余或未被认可的项目,并确定该工具的因子结构。以466名完成进餐行为问卷的家长作为标准对照来检验结构效度。采用已知群体验证法比较有和没有被诊断出喂养问题的儿童之间的PediEAT得分。97名家长在2周后重复填写PediEAT,以此检验PediEAT的时间稳定性。
采用方差最大化旋转的主成分因子分析支持一个四因子模型,该模型解释了总方差的39.4%。这四个分量表(生理症状、进餐问题行为、选择性/限制性进食、口腔加工)显示出可接受的内部一致性(系数阿尔法分别为:0.92、0.91、0.83、0.83)。结构效度通过两种方式得到支持。PediEAT与进餐行为问卷相关(r = 0.77,P < 0.001),并且有和没有被诊断出喂养问题的儿童之间的总分及分量表得分存在显著差异(P < 0.001)。通过重测信度证明了时间稳定性(r = 0.95,P < 0.001)。
强大的心理测量特性支持在研究和临床实践中使用PediEAT。
