RCT of a reading aloud intervention in Brazil: Do impacts differ depending on parent literacy?

Parent involvement and children's academic achievement: Evidence from a census of public school students in Brazil

“…We thus found little evidence that parent education moderated the association between parent involvement and students' achievement in Brazil. This is consistent with evidence from Mendelsohn et al (2020), who found that parent education did not moderate the impacts of a read‐aloud parenting intervention in Brazil on children's early literacy and cognitive development. Interventions to promote parent involvement could target parents who have little experience with formal education themselves.…”

Supporting Reading Aloud Beginning Prenatally and in Early Infancy: A Randomized Trial in Brazil

“…Extending findings from a previous study with older children demonstrating that UBB effects were similar or greater for families with low parental literacy level, 13 this study showed that UBB was associated with reduced screen time and increased vocabulary for such families as well. The findings are consistent with limited research in LMICs demonstrating either similar or greater benefits of reading aloud programs for low-literacy parents.…”

“…12 In particular, a group-based reading aloud intervention (including book-lending) implemented in educational child care centers in northern Brazil, Universidade do Bebê (UBB), has shown effects on parenting and child outcomes for families with children aged 24 to 48 months. 6,8 UBB's impacts have been shown even for families with low parental literacy, 13 a potential barrier to program benefit 10 ; in fact, impacts were greatest for such families. Furthermore, UBB impacts on some child outcomes were mediated by cognitive stimulation.…”

Early childhood education effect on children’s vocabulary

“…The instruments listed in (i) to (iv) are used and validated internationally, were translated to Portuguese, adapted to the Brazilian context, and used in at least two studies in Brazil as far as we know (Weisleder et al, 2018;Mendelsohn et al, 2020). For each instrument, a two-parameter item response theory (IRT) model was estimated to generate an index.…”
