Objective:
Multiple studies show that behavioral couples therapy (BCT) is more
efficacious than individually-based therapy (IBT) for substance use and
relationship outcomes among men with alcohol use disorder (AUD). The present
study compared BCT with IBT for women with AUD.
Method:
Participants were women with AUD (N = 105) and their
male partners without SUD. Participants were mostly White and in their
forties. Women were randomized to equally intensive treatments consisting of
either BCT plus 12-step-oriented IBT or IBT only. Primary outcomes included:
Timeline Followback Interview percentage days abstinent (PDA) and Inventory
of Drug Use Consequences measure of substance-related problems. Secondary
outcomes included: Dyadic Adjustment Scale (DAS), Relationship Happiness
Scale (RHS), and Revised Conflict Tactics Scales measure of intimate partner
violence (IPV). Outcome data were collected at baseline, post-treatment, and
quarterly for 1-yr follow-up.
Results:
Compared to IBT only, BCT plus IBT had significantly better primary
outcomes of higher PDA and fewer substance-related problems during the 1-yr
follow-up period. Compared to IBT only, BCT had significantly higher male
RHS during the 1-yr follow-up. Women with lower pretreatment DAS had
significantly higher DAS following BCT versus IBT, and there was an
increasing advantage for BCT on female DAS over the follow-up. IPV was
significantly reduced from pretreatment to follow-up, with no differences
between treatment conditions.
Conclusion:
Results showed that BCT for women with AUD was more efficacious than
IBT in reducing substance use and substance-related problems and improving
partner relationships.
