Multivariate Behavioral Genetic Analysis of Parenting in Early Childhood

Abstract

SYNOPSIS: Objective. Caregivers play an important role in child development; in addition to instilling their norms and values in their children through socialization, caregivers modify their parenting practices in response to children’s characteristics. Previous studies have documented child genetic effects on parenting behaviors, but multivariate behavioral genetic examinations of parenting are scarce. Design. The current study examined the multivariate structure of child genetic and environmental influences on parenting in a sample of 236 individual twins aged 0–5 years, providing a total of 542 observations. Results. “Shared environments” (between-family environmental differences that are shared by twins reared in the same home, including parental characteristics, family socioeconomic status, and neighborhood characteristics) account for the majority of variation in parenting practices, whereas child genetic effects are more modest and occur more on specific parenting practices. Conclusion. Caregivers generally engage in similar parenting across children reared together and, at the same time, adjust their broad parenting approach and particularly their specific practices in response to genetically driven child characteristics. Future research may benefit from using a multidimensional framework to examine the different components and age-related transformations in these parent-driven and child-driven processes.
