Zusammenfassung: | Abstract Scales with evidence of validity and reliability are important to evaluate child development. In Brazil, there is a lack of standardized instruments to evaluate young children. This study investigated the psychometric properties of the Bayley Scales of Infant Development, Third Edition (Bayley-III). It was translated into Brazilian Portuguese, culturally adapted and tested on 207 children (12-42 months of age). Evidence of convergent validity was obtained from correlations of the Bayley-III with the: Peabody Developmental Motor Scale 2, Leiter International Performance Scale-R, Expressive Vocabulary Assessment List and Peabody Picture Vocabulary Test. Exploratory factor analyses showed a single component explaining 86% of the variance, supported by goodness-of-fit indexes in confirmatory factor analysis. The Bailey-III demonstrated good internal consistency with alpha coefficients greater than or equal to .90 and stability for fine motor scale only. These robust psychometric properties support the use of this tool in future national studies on child development.
Resumen Escalas con evidencia de la validez/fiabilidad son importantes para la evaluación del desarrollo infantil. En Brasil, faltan instrumentos estandardizados/normalizados para la evaluación en la primera infancia. Este estudio investigó las propiedades psicométricas de las Bayley Scales of Infant and Toddler Development-III, traducida y adaptada al portugués. Se evaluaron 207 niños (12-42 meses). Evidencias de validez convergente se observaron entre Bayley-III con: Escala de Desarrollo Motor de Peabody 2, Escala de Inteligencia Internacional Leiter-R, Lista de Evaluación de Vocabulario y Prueba de Vocabulario Expresivo Imágenes Peabody. El análisis factorial exploratorio indicó un componente que explica el 86% de la varianza, corroborado por buenos índices de ajuste en el análisis factorial confirmatorio. Bayley-III mostró buena consistencia interna, con coeficientes alfa de 0,90. La adecuación de las propiedades psicométricas puede contribuir al avance de la investigación en el contexto nacional en el área de evaluación del desarrollo infantil.

No Brasil, há escassez de instrumentos padronizados e normatizados para a primeira infância.
