Parental report may provide an inexpensive alternative to standardized assessments of children's development. We have adapted and validated a parental questionnaire on cognitive development for use with very preterm infants. Sixty-four 2-year-olds (28 males, 36 females) born less than 30 weeks' gestation (median 28.5 weeks, range 23 to 31 weeks), median birthweight 980g (range 500 to 1905g) were assessed using the Mental Development Index (MDI) of the Bayley Scales of Infant Development-II and the parental questionnaire. Significant correlations between parent report and MDI scores (r=0.54-0.68, p<0.001) indicated good concurrent validity. Diagnostic use of the parent report for predicting an MDI score of less than 70 was assessed by using receiver operating characteristic (ROC) curves. The optimal cut off produced equal sensitivity and specificity (81%), indicating good discriminatory power in diagnosing developmental delay. Test-retest reliability was demonstrated and accuracy of parent reporting was not affected by sociodemographic factors. Our questionnaire provides a valid outcome measure for use in randomized trials or large population surveys.
家长报告可能为儿童发育的标准化评估提供一种低成本的替代方法。我们对一份关于认知发育的家长问卷进行了改编和验证，以用于极早产儿。对64名2岁儿童（28名男性，36名女性）进行了评估，这些儿童出生时孕周小于30周（中位孕周28.5周，范围23至31周），中位出生体重980克（范围500至1905克），使用贝利婴儿发育量表第二版的心理发育指数（MDI）和家长问卷进行评估。家长报告与MDI评分之间存在显著相关性（r = 0.54 - 0.68，p < 0.001），表明具有良好的同时效度。通过使用受试者工作特征（ROC）曲线评估家长报告用于预测MDI评分低于70的诊断价值。最佳截断值产生了相等的敏感性和特异性（81%），表明在诊断发育迟缓方面具有良好的鉴别能力。证明了重测信度，且家长报告的准确性不受社会人口统计学因素的影响。我们的问卷为随机试验或大规模人群调查提供了一种有效的结果测量方法。
