Physical Discipline, Deprivation, and Differential Risk of Developmental Delay Across 17 Countries

Parenting behaviors have been studied largely in isolation with regard to child development in cross-national contexts. We examine and compare the relative strength of association between physical discipline and deprivation with risk of children's socioemotional and cognitive developmental delay in a cross-national sample.

The sample was drawn from the UNICEF Multiple Indicator Cluster Survey. Analyses used observations with data on parental physical discipline, parenting behaviors associated with deprivation, and child developmental outcomes. The present analysis included 29,792 children aged 36-59 months across 17 countries. Using the Early Child Development Index, risk for cognitive or socioemotional developmental delay was indicated if a child could not accomplish 2 or more items within that specific subdomain. Overall risk for delay was indicated if a child was at risk in either subdomain. Associations among discipline, deprivation, and delay were assessed using multivariable logistic regression.

Five of the 7 exposures were associated with risk of overall developmental delay. Physical discipline (odds ratio [OR] = 1.49 [95% CI = 1.39, 1.59]; p < .001) had the largest association with risk for socioemotional delay. Not having books (OR = 1.62 [95% CI = 1.42, 1.84]; p < .001) and not counting with the child (OR = 1.47 [95% CI = 1.32, 1.64]; p < .001) had the largest associations with risk of cognitive delay.

The exposures of physical discipline and deprivation measured here have distinct associations with risk of socioemotional and cognitive delay cross-nationally. Programmatic and clinical interventions should seek to act on adversities that are relevant to the targeted delay.
