The Role of Neighborhood and Parenting in the Development of Effortful Control During Early Childhood.

Background: Effortful control (EC) is a self-regulatory ability that is linked to many individual child outcomes and is influenced by ecological variables (e.g., family, parenting). The influence of neighborhood-level variables has not been thoroughly examined. Objective: The present study examined poorer neighborhood quality as a predictor of EC development, and the moderating role of parenting in relation to poor neighborhood quality and EC development. Method: Latent growth curve modeling analyses were used to assess changes in EC across time in a community sample (N = 796) of 4 year-olds. Subsequent analyses were run to determine the impact of neighborhood quality and the moderating role of parenting in relation to EC development. Results: Analyses indicated that children experienced steady and significant improvements in EC across ages 4, 5, and 6. Independent of socioeconomic status, poorer neighborhood quality significantly predicted age 4 EC level and the growth in EC from ages 4 to 6. Hostile parenting emerged as a significant moderator of the relationship between poorer neighborhood quality and age 4 EC level. Conclusions: This study underscores the importance of examining neighborhood context in relation to individual child outcomes.
