The predictive value of developmental testing of children under the age of 2 years

The relationship between development during the first 2 years of life and similar aspects of development at 4 years of age was investigated. The neuro-sensory motor and general developmental abilities of 124 (62 male and 62 female) low birth weight or mechanically ventilated infants were assessed at 4, 8, 12, 18, 24 and 48 months after the expected date of delivery. Results indicated a positive relationship between development on all occasions >2 years and outcome at 4 years of age. Neuro-sensory motor assessment at 8 months of age was the most valuable in identifying children at risk for difficulties in motor development at 4 years of age. The most accurate prediction of intellectual developmental ability were obtained at 12 and 18 months of age
