Bayley III in Vietnamese children: lessons for cross-cultural comparisons

Abstract

Background: There are limited psychometric reports of construct validity following adaptation of the Bayley Scales of Infant and Toddler Development 3rd edition (Bayley III). This paper aims to demonstrate a process of assessing reliability, validity, and gender equivalence of the adapted tool for Vietnamese children. Methods: We evaluated cognitive, fine motor, gross motor, expressive communication and receptive communication subtests of the adapted tool in 267 healthy urban Vietnamese children. Subsets of participants were used to evaluate inter-observer and test-retest reliability. Confirmatory factor analysis (CFA) was carried out to evaluate construct validity and measurement invariance between genders. Results: The adaptation demonstrated good inter-observer and test-retest reliability. CFA indicated that a construct representing a single underlying factor showed the best fit, although relationships between the observed scores and the latent traits underlying the scores varied between age groups. Within age groups, relationships between observed scores and these factors were not significantly influenced by gender. Conclusions: The Vietnamese Bayley III demonstrated good internal consistency and reliability. A latent structure with one general factor and additional residual correlations that change with age is supported by the theoretical understanding of child development. This is the first study to demonstrate gender invariance by age group. This adaptation is suitable for further research studies in urban Vietnamese children, but further work is needed to extend its applicability more broadly across Vietnam.

Poor Head Growth Is Associated with Later Mental Delay among Vietnamese Preterm Infants: A Follow-up Study

“…At 24 months CA, neurodevelopmental performances were assessed using subtests of Bayley Scales of Infant and Toddler Development - 3rd Edition (Bayley-III) including cognitive, receptive and expressive language, fine and gross motor. The Bayley-III was translated and was adapted for use in Vietnamese children [ 25 ]. Scale scores were combined to generate composite scores.…”

“…These cut-off points were derived from a reference of healthy Vietnamese children. Details of 2-year neurodevelopment of preterm infants in the cohort are reported elsewhere [ 25 , 26 ].…”

Child development assessment: Practitioner input in the revision for Griffiths III

“…Confirmatory factor analysis (CFA) demonstrated construct validity by evaluating relationships between test scores and different underlying traits/factors. The authors concluded that the test scores best modelled three underlying traits: motor, language and cognitive factors (Sun et al, 2019) (Best & Miller, 2010;Fuchs et al, 2010;Haden et al, 2011;Pellegrini, 2009). In addition, there has been an extensive The GMDS-ER has been translated into Italian, French, Portuguese, Chinese and Russian since its publication in English in 2006.…”

A Psychometric Study of the Bayley Scales of Infant and Toddler Development – Third Edition in the Russian Federation

“…Существенным ограничением для широкого прикладного применения Bayley-III в РФ является отсутствие возрастных нормативных показателей для российской популяции детей. Результаты кросс-культурных исследований показывают необходимость адаптации этой методики с учетом языковых различий и социальных особенностей населения (Azari et al, 2017;Hegde, Rao, Raguram, & Gangadhar, 2013;Hoskens, Klingels, & Smits-Engelsman, 2018;Fuiko et al, 2019;Steenis, Verhoeven, Hessen, & van Baar, 2015;Sun et al, 2019). Использование Bayley-III без предварительной стандартизации может привести к неверной интерпретации полученных результатов, выражающейся в переоценке или, напротив, недооценке уровня развития ребенка.…”
