Children learn from their parents but there is another parent’s related impact that is significant in the development of a child. The first and foremost of such variables are the behavior of the parents with the child.

This study was done to examine the individual and interactive effects of child negativity and parental affective behaviors. The sample size of the study included the 450 children who were 4 years of age on externalizing issues exhibited by children at 5 years of age using a subsample of children with developmental delays drawn from a nationally representative data set.

Hierarchical multiple regression analyses were used for the analysis of the research questions. The obtained results from the collected data indicated that negativity displayed by parents when children were 4 years of age was associated with more externalizing issues when children reached age 5.

The study concluded through its findings that the interventions targeting emotional regulation in preschool-age children with developmental delays should target child and parent effective expression, and equip parents with skills to manage negative emotions.
