Integrative Couple Treatment for Pathological Gambling

Study Overview
=================
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gambling Symptom Assessment Scale (G-SAS) | Outcome measure for Gamblers The G-SAS is a 12-item self-rated scale designed to assess gambling symptom severity and change during treatment. Each 12-item scale has a score ranging from 0 - 4 (adjective anchors for 0 and 4 vary for each item but 0 means no symptoms and 4 means extreme symptoms). All items ask for an average symptom based on the past 7 days (average urge, frequency, duration and control,thoughts associated with gambling,time spent on gambling,anticipatory tension and/or excitement, emotional distress). The total score ranges from 0 to 48. A score between 8 and 20 is an indicator of low urges to gamble, between 21 and 30, moderate urges, between 31 and 40 severe urges and a score of over 40 reveals the presence of extreme urges in the player. | Admission, 3, 9 and 18 month post-admission (The first admission was March 2011 and the last admission will be June 2016) | 
| Frequency of the Most Problematic Game | Outcome Measure for Gamblers Among 12 types of gambling activities, the highest frequency of gambling behaviors for the past 6 months (never = 0; every or almost every day=5). Maximum score is 5. The higher is the score, the higher is the frequency. | Admission, 3, 9 and 18 month post-admission (The first admission was March 2011 and the last admission will be June 2016) | 
| Detection of Gambling Problems and Services Need (Détection et Besoin d'Aide en Regard du Jeu Excessif- DÉBA-Jeu) | Outcome Measure for Gamblers The DEBA-Jeu is a very brief screening grid comprising eight Likert-type items in five points (never = 0, always = 4). The eight items form a scale where the total score varies between 0 and 32. The suggested breaking points are as follows: 0 to 1 = No problem gambling; 2 to 5 =Problem gambling ; 6 to 24 = High probability of problem gambling. | Admission, 3, 9 and 18 month post-admission (The first admission was March 2011 and the last admission will be June 2016) | 
| Canadian Problem Gambling Index (CPGI) | Outcome measure for Gamblers The Canadian Problem Gambling Index (CPGI) is a 9-item measure with a 4-point Likert-type scale (0 = Never, 3 = Almost always).It asks questions about an individual's gambling habits in the last three months from four categories: Gambling involvement; Problem gambling behaviour; Adverse Consequences; Correlates of problem gambling. Scores for the nine items are summed, and the results are interpreted as follows: 0 = non-problem ; 1-4 = low risk; 5-7 = moderate risk; 8 and + (maximum 27) = probable pathological player. | Admission, 3, 9 and 18 month post-admission (The first admission was March 2011 and the last admission will be June 2016) | 
| Canadian Dollars Spent on Gambling | Outcome measure for Gamblers Total Money spent in canadian dollars for all gambling activities during the last 3 months previous each research interview. | Admission, 3, 9 and 18 month post-admission (The first admission was March 2011 and the last admission will be June 2016) | 
| Impaired Control Over Gambling Scale (ICOG) | Outcome Measure for Gamblers The ICOG is used to measure two aspects of control related to the JHA processes, namely the level of control over the desire to start playing (e.g., when I decide not to play, I watch stick to that decision) as well as the level of control once the game has started (e.g., when I knew I had little time to play, I would limit myself to the scheduled time). This questionnaire has a total of 10 items and uses a 5-point Likert-type scale ranging from Never = 1 to Always = 5, with 4 inverted items. The total score varies between 10 and 50. A high control represents a score between 10 and 16, a moderate control between 17 and 23 and a score of 24 and more presents a low control in the player. | Admission, 3, 9 and 18 month post-admission (The first admission was March 2011 and the last admission will be June 2016) | 
| Inventory of Erroneous Beliefs Related to Gambling (Inventaire Des Croyances liées Aux Jeux - ICROLJ)-Gambler | Outcome Measure for Gamblers This questionnaire measures people's beliefs about gambling.
