Parental communicative input as a protective factor in Bangladeshi families living in poverty: A multi‐dimensional perspective

Abstract

AbstractStudies from high‐income populations have shown that stimulating, supportive communicative input from parents promote children's cognitive and language development. However, fewer studies have identified specific features of input supporting the healthy development of children growing up in low‐ or middle‐income countries. The current study proposes and tests a multi‐dimensional framework for understanding whether and how caregiver communicative input mediates the associations between socio‐economic conditions and early development. We also examine how caregiver conceptual scaffolding and autonomy support uniquely and synergistically explain variation in child outcomes. Participants were 71 Bangladeshi families with five‐year‐olds who were exposed to a range of biological and psychosocial hazards from birth. Caregiver‐child interactions during snack sharing and semi‐structured play were coded for caregiver conceptual scaffolding, autonomy support, and child engagement. Findings indicate that the two dimensions of input were correlated, suggesting that caregivers who provided richer conceptual scaffolds were simultaneously more supportive of children's autonomy. Notably, conceptual scaffolding and autonomy support each mediated associations between maternal education and child verbal intelligence quotient (IQ) scores. Further, caregivers who supported greater autonomy in their children had children who participated in conversations more actively, and these children in turn had higher performance IQ scores. When considered simultaneously, conceptual scaffolding was associated with verbal IQ over and above autonomy support, whereas autonomy support related to child engagement, controlling for conceptual scaffolding. These findings shed new light on how environmental factors may support early development, contributing to the design of family‐centered, culturally authentic interventions.

Such research is scarce in low‐ and middle‐income countries. The present study conceptualized and evaluated caregiver communicative input in Bangladeshi families along two interrelated yet distinct dimensions: conceptual scaffolding and autonomy support. Conceptual scaffolding and autonomy support individually mediated associations between maternal education and child verbal IQ, shedding light on protective factors in families living in poverty. Parents providing richer conceptual scaffolds were simultaneously more supportive of children's autonomy. However, the two dimensions each related to cognition and language through unique pathways.
