Bayley-III Scales of Infant and Toddler Development: Transcultural Adaptation and Psychometric Properties

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.

Cognitive and behavioral profile of Williams Syndrome toddlers

“…As the study aimed to track indicators of developmental delay, it was used the Denver II test. Although Denver Test did not have precision indicators similar to Bayley Scales of Infant and Toddler Development (21) , the results of delay in the group of children in all areas of the Denver test are similar to those found with Bayley, shown by a recent study (8) , whose authors evaluated 16 children between 3 months and 5 years old and, according to the data, there was a delay check in all the areas evaluated by the test (8) . The Columbia test evidences also showed development delays, from the 5 children who were able to perform the test, all of them had very low scores for their age (4 of them presented results less than half of their chronological age), another indicator of developmental delay.…”

Development of the Dimensional Inventory of Child Development Assessment (IDADI)

“…In Brazil, the challenge to identify developmental problems among young children is aggravated by a lack of standardized instruments (Becker, Bandeira, Ghilardi, Hutz, & Piccinini, 2013;Madaschi, Mecca, Macedo, & Paula 2016). Even though there are some multidimensional instruments traditionally used internationally, only until 2018 three instruments were published in the Brazilian context: 1) the Bayley Scales of Infant Development (Bayley-III;Bayley, 2018) -it directly assesses children from one e to 42 months; 2) Denver-II Developmental Screening Test (Frankenburg et al, 2018) -aimed for children aged from birth to 72 months old and; 3) The Ages and Stages Questionnaire (ASQ-3) a parental report inventory for one to 66 month-old children validated by Filgueiras et al, (2013) but not yet commercially available.…”

“…It includes all aspects of NPMD with accurate data and excellent reliability standard. The test is subdivided into five domains: (1) cognitive, with 91 items; (2) language, which is divided into two subtests (receptive communication, with 49 items and expressive communication, with 48 items; (3) motor (subdivided into gross motor ability, with 72 items and fine motor ability, with 66 items); (4) social-emotional; and (5) adaptive behavior, the latter two being obtained from filling the scales by caregivers or parents of the child 7,9 .…”
