Using data from cohort 1 of the Early Growth and Development Study, a parent-offspring adoption sample (N= 361), we examined heritable (birth mother (BM) emotionality from the Adult Temperament Questionnaire) and environmental [adoptive parent (AP) positive (Alabama Parenting Questionnaire) and overactive parenting (Arnold Parenting Scale)] influences on child emotionality (Child Behavior Questionnaire) at age 6 and later internalizing and externalizing problems (Child Behavior Checklist) at age 7.
Preliminary analyses indicate that child negative emotionality was associated with AP overreactive parenting (r = .33, p < .01) but not with BM negative emotionality (r = .02, ns) or later child externalizing (r = .02, ns) or internalizing problems (r = .02, ns). Child positive emotionality was inversely associated with both AP overreactive (r = -.15, p < .05) and positive associated with positive parenting (r = .29, p < .01) but not with BM positive emotionality (r = -.04, ns), later child externalizing (r = -.06, ns) or internalizing problems (r = -.06, ns).
These preliminary findings support prior work of associations between parenting and child emotionality. There is no evidence that the heritable influences of birth mother negative emotionality play a role in these preliminary associations. There is also no association between child emotionality and child behavior problems. Additional analyses will examine possible moderation of associations between parenting and child emotionality by birth mother emotionality or other behaviors, such as externalizing or internalizing problems using both cohort 1 and 2 of this sample (N=561). By elucidating the mechanism by which family relationships influence the emotionality and later adjustment of the child, prevention and intervention programs will be able to effectively target behaviors that are shown to have environmental effects within the family.
