Treating paternal alcoholism with learning sobriety together: effects on adolescents versus preadolescents.

The purpose of this study was to determine whether Learning Sobriety Together, a treatment for substance abuse that combines behavioral couples therapy and individual counseling, had comparable secondary benefits on the internalizing and externalizing behaviors of adolescent versus preadolescent siblings living in homes with their alcoholic fathers (N = 131) and their non-substance-abusing mothers. During a 17-month assessment period, the association between parents' functioning (i.e., fathers' drinking as determined by percentage of days abstinent and parents' dyadic adjustment) and children's adjustment (as rated by mothers, fathers, and children's teachers) was stronger for preadolescents than for their adolescent siblings, particularly in terms of children's externalizing behaviors. Interventions that reduce paternal drinking and improve couple functioning may serve as an important preventative intervention for preadolescents in these homes, whereas adolescents may need more intensive interventions to address internalizing and externalizing symptoms.
