Background The Bayley Scales of Infant and Toddler Development is a standardised developmental assessment that assesses children up to 42 months. The goal of the assessment is to identify those children with developmental delay. The Ages and Stages Questionnaire (ASQ-3) is a standardised developmental questionnaire that parents complete. The purpose of the questionnaire is to identify those children who warrant a more detailed developmental assessment such as The Bayley Scales Assessment.

Aim To assess the ASQ-3 for identification of children with developmental delay in an Irish population.

Methods A cohort of 87 pairs of twins (174 children) was taken from an on-going larger twin study. All children were assessed with both the ASQ-3 and The Bayley Scales Assessment.

Results In our cohort, the ASQ-3 has a sensitivity of 95% and a specificity of 57%. Although the ASQ-3 will give some false positive results, it is a good screening tool for picking up children with potential developmental delay as very few children with true delay will be missed.

Discussion Although The Bayley Scales Assessment is the gold standard for assesment of developmental delay, it is time consuming and must be carried out by a qualified professional. Only those at highest risk for developmental delay are therefore assessed. Our results suggest that the ASQ-3 can be used a screening tool in low risk populations to identify those children who may be at risk for developmental problems.
