To validate the Ages and Stages Questionnaire (ASQ) and to measure average cognitive deficit in children born extremely preterm.


Parents of 30 term children aged 36-42 mo completed the ASQ and the children underwent the Wechsler Preschool and Primary Scales of Intelligence--Revised. In a second study, the ASQ was obtained in 22 children born extremely preterm and 19 term children at the age of 35-44 mo.


The overall ASQ score correlated significantly with IQ (p=0.007). The children born extremely preterm had an ASQ score of -1.06 SD below the score of the term children (p=0.048).


The ASQ identified a developmental deficit of the expected magnitude.
