    El “Test de Aprendizaje y Desarrollo Infantil” (TADI) es una escala de tamizaje del desarrollo para niños/as de 6 a 72 meses construida en Chile.Objetivo: Determinar la validez de la primera edición de TADI muestra nivel poblacional.Metodología:Análisis psicométrico secundario de una muestra de 11.283 niños/as chilenos que participaron de la Encuesta Longitudinal de Primera Infancia (ELPI) 2012. Se evaluó validez convergente mediante el Análisis Factorial Confirmatorio (AFC), verificado mediante Análisis Factorial Exploratorio (AFE). Se consideraron variables sociales para la validez de constructo. Para la validez concurrente, sensibilidad, especificidad y correlación se tomaron como referencias las pruebas Battelle Developmental Inventory Segunda Edición (BDI-2) y el Test de Vocabulario en Imágenes Peabody (TVIP).Resultados: De los niños evaluados, 12,6% se categorizó en Retraso o Riesgo de Retraso, y 17,3% en categoría Alerta. El AFC arrojó buenos niveles de ajuste del modelo propuesto para los datos de la escala, en particular a edades mayores. El AFE reveló patrones diferentes para distintos rangos etarios. El TADI se correlacionó significativamente con los factores socioeconómicos, como la presencia de materiales de aprendizaje en el hogar, el nivel educativo del cuidador principal, el ingreso económico y la respuesta emocional de la madre. Se encontró correlación moderadamente positiva del TADI con el BDI-2 y el TVIP, con sensibilidad y especificidad cercanos a 0,70 al incluir la categoría Alerta.Conclusiones: Los adecuados valores psicométricos del TADI en una muestra poblacional ratifican su validez como instrumento de tamizaje del desarrollo de niños/as pequeños en Chile.

    <jats:sec> <jats:title>BACKGROUND:</jats:title> <jats:p>This study assessed the concurrent validity of the parent-completed developmental screening measure Ages and Stages Questionnaires, Third Edition (ASQ-3) compared with the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) in children born term, late preterm, or extremely preterm at 8, 18, or 30 months of corrected gestational ages (CGA).</jats:p> </jats:sec> <jats:sec> <jats:title>METHODS:</jats:title> <jats:p>Data were collected from 306 term and preterm children ages 8, 18, and 30 months’ CGA recruited from an ambulatory well-child clinic in Santiago, Chile. Parents completed the ASQ-3 in their homes, and afterward a trained professional administered the Bayley-III in a clinic setting. On the ASQ-3, the presence of any domain screened &amp;lt;2 SDs below the mean area score was considered a positive screen (indicating failure or delay). A Bayley-III score less than ≤1 SD indicated mild or severe delay.</jats:p> </jats:sec> <jats:sec> <jats:title>RESULTS:</jats:title> <jats:p>ASQ-3 showed adequate psychometric properties (75% sensitivity and 81% specificity) and modest agreement with the Bayley-III (r = 0.56). Sensitivity, specificity, and correlations between measures improved with testing age and in children who were born extremely preterm.</jats:p> </jats:sec> <jats:sec> <jats:title>CONCLUSIONS:</jats:title> <jats:p>Considering its psychometric properties, the ASQ-3 can be recommended for routine use in screening low-risk children at 8, 18, and 30 months’ CGA and is advisable to be included in follow-up programs for children with biological risk factors such as those born preterm.</jats:p> </jats:sec>

    <jats:sec> <jats:title>OBJECTIVES:</jats:title> <jats:p>The objective of this study was to evaluate the association between gestational age (GA) at birth and risk of developmental delay at 8 and 18 months of corrected postnatal age.</jats:p> </jats:sec> <jats:sec> <jats:title>METHODS:</jats:title> <jats:p>During 2008 to 2011, infants at a corrected postnatal age of 8 or 18 months attending health centers in Santiago, Chile, were recruited. Participants completed a form on biographical and demographic characteristics and the Chilean validated version of the Ages and Stages Questionnaires, Third Edition (ASQ). Logistic regression was used to detect the capacity of GA to predict scores &amp;lt; −2 SDs on the basis of the Chilean ASQ reference group, in at least 1 ASQ domain, adjusted by different control variables.</jats:p> </jats:sec> <jats:sec> <jats:title>RESULTS:</jats:title> <jats:p>A total of 1667 infants were included in the analysis. An inverse “dose response” relationship between developmental delay risk and GA at birth was found, both in the crude and adjusted models. Compared with those born full term, the odds ratio for developmental delay risk was 1.56 for those born early term (95% confidence interval [CI]: 1.19–2.06), 2.58 for infants born late preterm (95%CI: 1.66–4.01), and 3.01 for those born moderately preterm (95%CI: 1.59–5.71).</jats:p> </jats:sec> <jats:sec> <jats:title>CONCLUSIONS:</jats:title> <jats:p>An inverse dose-response relationship between GA and risk of developmental delay was found in the tested population. Future prospective studies and predictive models are needed to understand whether this higher developmental risk in moderately and late preterm infants is transient and modifiable or persists throughout life, allowing for better targeting of early-intervention strategies.</jats:p> </jats:sec>
