Insights

The Early Report by Infant Caregivers (ERIC) tool effectively screens for cognitive delay in preterm infants aged 10-24 months. It shows high sensitivity and negative predictive value, aiding in early detection.

Area of Science:

  • Neonatal development
  • Pediatric neurology
  • Developmental psychology

Background:

  • Preterm infants and those with low birthweight or perinatal complications are at higher risk for cognitive delay.
  • Early detection of cognitive delay is crucial for timely intervention and improved outcomes.
  • Existing screening tools may be time-consuming or require specialized administration.

Purpose of the Study:

  • To develop and validate the Early Report by Infant Caregivers (ERIC), a brief, parent-completed instrument.
  • To assess ERIC's ability to detect cognitive delay in high-risk infants aged 10-24 months.
  • To establish the diagnostic properties of ERIC, including sensitivity and specificity.

Main Methods:

  • Parents of 317 high-risk infants (preterm, low birthweight, or perinatal complications) completed the ERIC.
  • Infants were assessed using the Bayley Scales of Infant and Toddler Development-III cognitive scale as the criterion standard.
  • Instrument items were selected based on their association with developmental delay; sensitivity, specificity, and predictive values were calculated.

Main Results:

  • ERIC demonstrated high sensitivity (94.4%) in detecting cognitive delay, correctly identifying 17 out of 18 affected infants.
  • The tool exhibited high specificity (76.9%) and a very high negative predictive value (99.6%), indicating strong ability to rule out delay.
  • A truncated version of ERIC was developed for infants younger than 14 months.

Conclusions:

  • The ERIC instrument shows significant potential as a rapid screening tool for identifying cognitive delay in high-risk infants.
  • ERIC is particularly valuable for ruling out cognitive delay, facilitating early intervention planning.
  • Its parent-completed nature enhances feasibility for widespread use in clinical settings.
