Partner Effects and Bi-Directional Parent-Child Effects in Family Alcohol Use

Introduction: The current study investigated partner effects and bidirectional parent-child effects in family alcohol use. Methods: A full family, longitudinal design was used to test the hypotheses. Participants were 428 families, including mothers, fathers, and 2 children. Associations were measured over two waves with a 2-year interval, by means of structural equation modeling. Results: Whereas alcohol use of the younger children was affected by alcohol use of both parents, alcohol use of the older children was only affected by alcohol use of mother. Moreover, although the effects were small, alcohol use of older children affected later alcohol use of both parents. Conclusions: Associations between alcohol use of parents and children seem to be bidirectional. Future studies are needed to find out whether these findings are incidental or structural. If the effects are structural, potential underlying reciprocal processes within the family play a role in the development of adolescent alcohol use. Copyright © 2008 S. Karger AG.
