父母问卷是衡量结果的标准化测试的廉价替代品。儿童能力的父母报告先前已经过修订（PARCA-R），并经验证可用于2岁的极早产儿。这项研究重新验证了PARCA-R在更大且更具包容性的早产儿样本中评估认知的能力。164名儿童（82名男性，82名女性），妊娠< 32周（中位数29周，四分位距[IQR] 28- 30周）;中位数出生体重1200 g（IQR 925- 1463 g），使用贝利婴儿发育量表-第2版（BSID-II）的智力发育指数（MDI）在2岁校正年龄进行评估。家长填写PARCA-R问卷。PARCA-R父母报告复合（PRC）评分和MDI评分之间的显著相关性（r=0.77，95%置信区间[CI] 0.69-0.82，p < 0.01）证明了同时有效性。接收器操作特性确定的PRC截止值< 44具有最佳区分能力（曲线下面积0.92），识别MDI < 70，灵敏度为85%（95% CI 0.58-0.96），87%特异性（95% CI 0.81-0.92）、98%阴性预测值（95% CI 0.95-1）和37%阳性预测值（95% CI 0.22-0.54）。PARCA-R在识别2岁时极早产儿认知延迟方面具有良好的同时效度和诊断实用性。它是有用的结果测量，发展筛选，并促进家长参与随访。
Parental questionnaires are inexpensive alternatives to standardized testing for outcome measurement. The Parent Report of Children's Abilities has previously been revised (PARCA-R) and validated for use with very-preterm infants at 2 years of age. This study revalidated the PARCA-R for assessing cognition in a larger and more inclusive sample of preterm infants. One hundred and sixty-four children (82 males, 82 females) of < 32 weeks' gestation (median 29wks, interquartile range [IQR] 28-30wks); and median birthweight 1200g (IQR 925-1463g) were evaluated using the Mental Development Index (MDI) of the Bayley Scales of Infant Development - 2nd edition (BSID-II) at 2 years' corrected age. Parents completed the PARCA-R questionnaire. Significant correlations between PARCA-R Parent Report Composite (PRC) scores and MDI scores (r=0.77, 95% confidence interval [CI] 0.69-0.82, p < 0.01) demonstrated concurrent validity. A receiver operating characteristic-determined PRC cut-off of < 44 had optimal discriminatory power (area under curve 0.92) for identifying MDI < 70, with 85% sensitivity (95% CI 0.58-0.96), 87% specificity (95% CI 0.81-0.92), 98% negative predictive value (95% CI 0.95-1), and 37% positive predictive value (95% CI 0.22-0.54). The PARCA-R has good concurrent validity and diagnostic utility for identifying cognitive delay in very-preterm infants at 2 years of age. It is useful for outcome measurement, developmental screening, and facilitating parental involvement at folow-up.
