A Longitudinal Investigation of the Affective Environment in Families With Young Children: From Infancy to Early School Age

Abstract

We examined the affective environment in 102 families studied longitudinally when children were 7, 15, 25, 38, 52, and 67 months of age. At each assessment, every mother-child and father-child dyad was observed in typical daily contexts. Each person's emotions of affection, joy, and anger were coded. Both parents rated marital satisfaction when children were 15, 52, and 67 months. Growth curve analyses, using Actor-Partner Interdependence Modeling, examined (a) developmental changes in emotions, (b) within-relationship influences of the partner's emotions, (c) across-relationship influences of emotions in other parent's interactions with the child, and (d) associations between marital quality and emotions over time. Parents' emotional expressiveness was highest early in the child's development, and declined thereafter. Children's anger was highest at 15 months of age, and declined thereafter, and their positive emotions, particularly with mothers, increased over time. Generally, one's positive emotions and better marital quality were associated with greater positive emotion within- and across-relationships, whereas one's anger was associated with greater anger within- and across-relationships. However, any emotion expression elicited greater affection in the interaction partner. Parents' neuroticism did not account for the convergence of emotions across relationships. © 2010 American Psychological Association.
