dc.description.abstractObjective To compare the predictive value of the Spanish Ages & Stages Questionnaire third edition adapted for Chilean population (ASQ-Cl) and the Bayley Scale of Infant and Toddler Development 3rd edition (Bayley-III) for cognitive delay at school age, and to identify the domain predictors. Methodology Data were collected from 306 term and preterm children of medium-high socio-economic level enrolled in a prospective cohort study. Developmental outcomes at 8, 18 and 30 months were assessed via the ASQ-Cl and Bayley-III; at 6–8 years cognitive development was assessed using the Wechsler Intelligence Scale for Children (WISC-III). The area under the curve (AUC), sensitivity, specificity and predictive values were calculated, and logistic regression analysis was used. Results Of 227 children studied, 6.6% had cognitive delay. ASQ-Cl and Bayley-III generate equivalent AUC [0.77 and 0.80]. Sensitivity 67% and 53%; specificity of 72% and 88%, positive predictive value of 14% and 24%, negative predictive values of 97% and 96% respectively. Greater predictive validity was obtained at 30 months assessment. Deficit in the communication and gross motor skills and problem-solving domains of the ASQ-Cl and all the Bayley-III domains were significantly associated with cognitive delay. Conclusions ASQ-Cl can be used to identify children at risk for cognitive delay at 6–8 years of age, being comparable with the Bayley-III. Some domains of ASQ-Cl and all domains of Bayley-III were significant predictors for cognitive delay. These results support the use of ASQ-Cl as a screening tool for developmental delay.es
