Abstract
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.
