The impact of intimate partner violence on child development in Peru
MetadataShow full item record
The researchers used longitudinal data from a cohort of Peruvian children (n=1,720) tracked starting at the age of 1 year old to test the association between alcohol-induced physical IPV (intimate partner violence) against the mother during the child’s first two years of life, and the child’s cognitive, socio-emotional and schooling outcomes between the ages of 5 and 8. Multivariate regression techniques are used to estimate the relationship of interest, as they allow for controlling of child, household, and community characteristics. They find that early life exposure to IPV is negatively associated with cognitive outcomes (vocabulary and math test scores) for all children, and with self-efficacy for girls. The authors find no association with child’s self-esteem and age of school enrollment indicators. The effects are larger among children whose mothers are better educated and live in urban areas. Results remain robust across different specifications and after isolating changes in relevant variables over time.
