ABSTRACT
Abstract Objective The present study aims to analyze the psychometric properties and general validity of the Caregiver Reported Early Development Instruments (CREDI) short form for the population-level assessment of early childhood development for Brazilian children under age 3. Method The study analyzed the acceptability, test-retest reliability, internal consistency and discriminant validity of the CREDI short-form tool. The study also analyzed the concurrent validity of the CREDI with a direct observational measure (Inter-American Development Bank's Regional Project on Child Development Indicators; PRIDI). The full sample includes 1,265 Brazilian caregivers of children from 0 to 35 months (678 of which comprising an in-person sample and 587 an online sample). Results Results from qualitative interviews suggest overall high rates of acceptability. Most of the items showed adequate test-retest reliability, with an average agreement of 84%. Cronbach's alpha suggested adequate internal consistency/inter-item reliability (α > 0.80) for the CREDI within each of the six age groups (0-5, 6-11, 12-17, 18-23, 24-29 and 30-35 months of age). Multivariate analyses of construct validity showed that a significant proportion of the variance in CREDI scores could be explained by child gender and family characteristics, most importantly caregiver-reported cognitive stimulation in the home (p < 0.0001). Regarding concurrent validity, scores on the CREDI were significantly correlated with overall PRIDI scores within the in-person sample at r = 0.46 (p < 0.001). Conclusions The results suggested that the CREDI short form is a valid, reliable, and acceptable measure of early childhood development for children under the age of 3 years in Brazil.
Resumo Objetivo O presente estudo visa analisar as propriedades psicométricas e a validade geral do formulário curto dos Instrumentos sobre o Desenvolvimento na Primeira Infância Relatado por Cuidados (CREDI) para avaliação em nível populacional do desenvolvimento na primeira infância de crianças brasileiras com menos de três anos. Método O estudo analisou a aceitabilidade, a confiabilidade teste-reteste, a consistência interna e a validade discriminante da ferramenta CREDI. O estudo também analisou a validade concorrente do CREDI com uma medida observacional direta (Projeto Regional sobre os Indicadores de Desenvolvimento na Infância do Banco Interamericano de Desenvolvimento; PRIDI). A amostra total inclui 1.265 cuidadores brasileiros de crianças de 0 a 35 meses (678 em uma amostra presencial e 587 em uma amostra on-line). Resultados Os resultados das entrevistas qualitativas sugerem altas taxas gerais de aceitabilidade. A maior parte dos itens mostrou confiabilidade teste-reteste adequada, com concordância média de 84%. O coeficiente alfa de Cronbach sugeriu consistência interna/confiabilidade entre itens (α > 0,80) para o CREDI em cada uma das seis faixas etárias (0-5 α = 6-11, 12-17, 18-23, 24-29 e 30-35 meses de idade). As análises multivariadas da validade do constructo mostraram que uma proporção significativa da variação nas pontuações do CREDI pode ser explicada pelo sexo da criança e pelas características familiares, mais importante o estímulo cognitivo em casa relatado pelo cuidador (p < 0,0001). Com relação à validade concorrente, as pontuações do CREDI foram significativamente correlacionadas às pontuações gerais do PRIDI na amostra presencial em r = 0,46 (p < 0,001). Conclusões Os resultados sugerem que o formulário curto CREDI é uma medida válida, confiável e aceitável de desenvolvimento na primeira infância para crianças com menos de três anos no Brasil.

Summary Introduction: While a growing body of evidence has investigated the relationship between maternal mental health and child development, evidence on children’s early life outcomes remains mixed. We analyze the empirical relationship between maternal depression and children’s development at age one using data from the São Paulo Western Region Cohort project. Method: Seven hundred and ninety-eight (798) mother-child dyads living in the Butantã-Jaguaré’ region of São Paulo were assessed through a home visit between January and March 2015. Maternal mental health was assessed using the Edinburgh Postnatal Depression Scale (EPDS). Mothers were classified as “possibly depressed” if their EPDS score was between 10 and 13 and as “likely depressed” if their EPDS score was > 13. The child outcomes analyzed were height, weight, and overall development as assessed by the Ages and Stages Questionnaire (ASQ). Height and weight were age-normalized using WHO growth standards. Stunting was defined as height-for-age z-score (HAZ) < -2. Obesity was defined as body mass index z-score (BMIZ) > 2. Adjusted and unadjusted linear regression models were used to assess the associations between Edinburgh scores and child outcomes. Results: No association was found between maternal depression variables and children’s height, weight, stunting, and obesity. Positive associations were found between possible depression and ASQ (delta = 0.33; 95CI 0.11-0.54; p-value<0.01); no associations were found between likely depression and any of the outcomes analyzed. Conclusion: The results from this study suggest that symptoms of maternal depression are not associated with delays in child development in the study setting analyzed. Further research will be needed to understand this lack of association: while it is possible that caregivers’ mental health did not affect caregiving behavior, it is possible that the effect of maternal depression can vary according to timing, persistence, and intensity. It is also possible that the EPDS instrument may fail to identify mothers with clinical depression, or that children with depressed mothers get increased support from other family members or public early childhood focused programs.
