Brief summary: The aim of the study is to compare marital treatment to individual treatment for pathological gambling.

Detailed description: The study as two goals: evaluate the efficacy of couple treatment for pathological gambling and develop a better understanding of the individual (substance use, mental health) and couple dimensions (communication, marital satisfaction, violence) as intermediate variables explaining this efficacy. Couples will be randomized between the couple treatment and the treatment as usual (individual or group). The experimental couple treatment is offered over 8 to 12 sessions of 90 minutes. The couple treatment called (Integrative Couple Therapy for Pathological Gambling - ICT-PG) is inspired by the "Alcohol Behavior Couple Therapy" from Epstein and McCrady, to which the team added diverse components to adjust to gamblers. During the sessions, the focus is on a) reducing/stopping gambling behaviors, b) helping the partner to stop behaviors facilitating gambling habits and rise the frequency of behaviors incompatible with gambling habits and c) improve marital components (communication, sharing positive moments, negotiation, mutual support).

The control group receives individual or group treatment as already offered by the specialized centers in addiction. Their partner can receive individual intervention if desired. All participants are recruited in Specialized Addiction Treatment Centers in Quebec province, Canada. Evaluation of participants is done at admission, three, nine and 18 months post-admission.

Repeated measures ANOVA will be used to compared evolutions of groups over time. Multiple regression will allow the estimation of components roles into as intermediate variables to predict rehabilitation.
