Abstract
OBJECTIVE:Alcohol Behavioral Couple Therapy (ABCT) is an efficacious alcohol treatment. The purpose of the study was to describe patient and partner language and therapist behavior during therapy sessions and test a proposed causal model linking active ingredients of ABCT as measured by therapist behaviors, hypothesized mechanisms of behavior change as measured by in-session patient and partner language, and alcohol use outcomes. METHOD:Data came from couples in four ABCT clinical trials (N = 188; 86 males, 102 females, and their partners). Patient and partner verbal behaviors in session one and a mid-treatment session were coded using the System for Coding Couples' Interactions in Therapy-Alcohol. Therapist behavior was coded using the Couples Treatment Integrity Rating System. Percent days abstinent was calculated from daily drinking data for the first and second half of treatment and six months post-treatment. RESULTS: Therapists delivered an adequate level of the ABCT interventions during treatment. During treatment, couples increased positive behaviors, talked less about drinking, and decreased their amount of motivational language. Therapist behaviors did not predict patient or partner behaviors during treatment or drinking outcomes. Partner advice in the first session predicted poorer drinking outcomes. At mid-treatment, patient behaviors as a block, and specific behaviors of contemptuousness toward their partner and sustain talk, predicted poorer drinking outcomes. CONCLUSIONS: During ABCT, patients decrease their drinking, and patient and partner behaviors change in predicted ways. Partner advice, patient contemptuousness, and patient sustain talk predicted poorer outcomes. Analyses of within-session verbal behavior did not support the hypothesized mechanisms for change for ABCT.
