From this vantage, a promising approach is Behavioral Couples Therapy [BCT] for alcoholism and drug abuse, a comprehensive psychosocial intervention for substance abuse that focuses both on reducing addiction severity, improving couple adjustment, reducing interparental conflict and intimate partner violence (IPV), and improving the family environment and psychological functioning. In a series of preliminary studies, the PI found that children whose substance-abusing fathers and nonsubstance-abusing mothers participated in BCT displayed higher psychosocial adjustment at posttreatment and during an extended follow-up than youth whose substance-abusing fathers participated in individual-based treatment (IBT) or whose parents participated in a couples-based attention control treatment. These findings indicate that BCT may extend beyond the couple to their children and may provide an entry point into the family system from which to improve the adjustment of these youth.
