Early intervention in the path to alcohol problems through conduct problems: treatment involvement and child behavior change.

A program for the prevention of conduct problems among preschool-age sons of alcoholic fathers was implemented to interrupt what is likely to be a major mediating factor in the development of alcoholism in later years. A population-based sample of 42 families participated in a 10-month intervention involving parent training and marital problem solving. Differences in treatment outcome were examined, with the expectation that level of treatment involvement--entailing both level of participation and level of investment--would account for variability in child outcome at termination. Significant changes in positive and negative child behaviors were observed only within the group of families who completed the program and where the mothers demonstrated a higher level of treatment investment. When pretreatment child, parent, and family predictors of child behavior change were accounted for, subsequent analyses identified maternal treatment investment as a significant predictor of child outcome.
