The ASQ did not predict low IQ scores when children born VPT were six years

Abstract

Aim: There is a need for methods that can provide valid assessment tools in a follow-up programme without great financial costs. This study assessed the accuracy of the 60-month Ages and Stages Questionnaire as a screening tool to predict a low intelligence quotient score at 6 years in children born very preterm.

Methods: Totally, 54 children participated in a six-year follow-up study, which included an intelligence quotient test at 6 years of age and a 60-month Ages and Stages Questionnaire at four and a half or 5 years of age at respond. We used the receiver operating characteristic curve and evaluated the optimal cut-off score to predict a low intelligence quotient score.

Results: At four and a half years, the optimal cut-off value for predicting a low intelligence quotient score was 242, with a sensitivity of 67% and a specificity of 59%. At 5 years, only one child had a low intelligence quotient score, and the analysis was not performed.

Conclusion: Our results did not support the use of the 60-month Ages and Stages Questionnaire as a valuable screening tool to predict a low intelligence quotient score in children born very preterm at 6 years of age.
