Motivational interviewing with couples: A theoretical framework for clinical practice illustrated in substance use and HIV prevention intervention with gay male couples.

Epidemiological data indicate the need to address substance use and sexual HIV transmission risk among gay and bisexual men in relationships. While brief Motivational Interviewing (MI) delivered to the individual has shown efficacy in reducing sexual HIV risk with casual partners and substance use, the application of MI with couples has received less attention. Most studies of MI with couples have conceptualized the "spouse" or partner as an adjunct participant in the treatment of an identified client. We propose a theoretical framework for conducting MI with a couple, which approaches the couple as the identified client, and may be adopted when either one or both partners engage in the target behavior. We then discuss similarities between MI-processes conceptualized with our proposed framework and those that are salient in existing couples therapies. We utilize case examples from brief MI sessions targeting substance use and sexual HIV risk in gay male couples to illustrate three phenomena unique to the implementation of MI with couples: 1) interpersonal ambivalence; 2) the role of dyadic functioning in tolerating and resolving interpersonal ambivalence; and 3) joint goal formation as a prerequisite to the planning phase of MI. Connecting these phenomena with the transformation of motivation and accommodation processes outlined in Couples Interdependence Theory, this paper suggests that brief MI may be a promising modality for substance use and HIV risk reduction interventions with couples generally and gay couples specifically.
