Overview

Brief Summary

The aim of the study is to compare couple-based treatment to individual treatment (treatment as usual) for addiction (gambling or substance use disorder).

Detailed Description

Background:Couple-based intervention is one of the clinical innovations to increase access, retention and effectiveness of treatment in the field of addiction.Couple-based intervention for the treatment of problems related to gambling or substance use disorder (GD/SUD) is more effective than no treatment and the subjective experience of the members of the couple illustrates important clinical gains (better understanding addiction, resolve conflicts, etc.). A study conducted by the research team revealed a better effectiveness of couple-based treatment for GD than the individual treatment usually offered. Despite these positive results, this study highlighted a need to improve the couple intervention model (Integrative Couple Treatment for Pathological Gambling- ICT-PG). First of all, it did not allow to reach people having a SUD. Previous studies conducted by the research team also illustrated the need for more clinical work on serious relationship injuries caused by gambling. The investigators also accentuated their work on the strategies used by the partners and having an impact on the gambler's gambling behaviors. Goal : Evaluate the effectiveness of a couple-based treatment (Integrative Couple Therapy for Addiction ICT-A; experimental group) compared to the individual treatment usually offer (control group) for people with GD/SUD. Method/Design : A sample of at least 100 couples will be randomized to either ICT-A (experimental group) or the usual individual treatment (control group). The couple treatment called Integrative Couple Therapy for Addiction (ICT-A) 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 or substance use behaviors, b) helping the partner to stop behaviors facilitating gambling habits or substance use and rise the frequency of behaviors incompatible with gambling habits or substance use c) improve marital components (communication, sharing positive moments, negotiation, mutual support).The control group receives individual treatment as already offered by the specialized centers in addiction. All participants are recruited in Specialized Addiction Treatment Centers in Quebec Province, Canada. Repeated measures will be conducted at admission, 6, 12 and 18 months post-admission on the addiction's severity (primary outcome), on various couples' dimensions (secondary outcome) and various indicators of personal well-being (secondary outcome).In order to compare the effectiveness of the two treatment modalities, a series of regression analyzes will be carried out taking into account the correlation between the observations for the same individual and measurements repeated over time (linear mixed models; PROC MIXED of SAS).

Primary Outcomes

Change in Self-reports of alcohol, substance use and gambling with the Time-Line Follow-Back (TLFB) in the last 90 days-Gamblers

Time Frame: in the last 90 days of admission, 6,12 and 18 months post-admission (The first admission is anticipated for april 2023 and the last in march 2024)

Outcome measure for Gamblers The TLFB evaluates the frequency and quantity of substance consumed (alcohol, cannabis, other drugs) and gambling behaviours in the last 90 days, based on the personal definition of each user (none, low, moderate, high).

Change in Global Improvement Rate-Gambler

Time Frame: in the last six months of admission, 6,12 and 18 months post-admission (The first admission is anticipated for april 2023 and the last in march 2024)

Outcome measure for Gamblers This scale (of one question only) is used to document the perceived improvement in terms of difficulties in controlling one's gambling and substance use behaviors according to the treatment received. On a 7-point Likert scale (1 = very great degradation; 4 = no change; 7 = very great improvement), the individual evaluates the extent to which he has changed their gambling and substance use compared to prior the treatment. The closer the score is to 7, the more progress the person feels he or she has made, while a score close to 4 indicates no change and a score close to 1 indicates that the situation has worsened (max=7, min=0).

On a 7-point Likert scale (1 = very great degradation; 4 = no change; 7 = very great improvement). The individual assesses the extent to which his or her partner has changed his or her gambling and substance use patterns from before treatment. The closer the score is to 7, the more the person feels that his or her spouse has made progress, while a score close to 4 indicates no change and a score close to 1 that the situation has deteriorated (max=7, min=0).

Change in Alcohol, Smoking and Substance involvement and Screening Test (ASSIST) of the World Health Organization (WHO)-Gambler

Time Frame: in the last 90 days of admission, 6,12 and 18 months post-admission (The first admission is anticipated for april 2023 and the last in march 2024)

Outcome measure for Gamblers This 8-item tool is developed by a group of the World Health Organization (WHO) specialized in addiction. It detects the use of different substances from the gambler and proposes a threshold above which reported consumption behaviors are problematic (low risk: 0-3 for drug use and 0-10 for alcohol use, moderate risk: between 4-26 for drug use and between 11-26 for alcohol use, high risk 27 and more for alcohol and drug use).

Change in Craving Experience Questionnaire (CEQ)-Gamblers

Time Frame: in the last seven days of admission, 6,12 and 18 months post-admission (The first admission is anticipated for april 2023 and the last in march 2024)

Outcome measure for Gamblers The CEQ was developed based on intrusion theory, which conceives of craving as a cognitive-emotional phenomenon that begins with an intrusive and generally spontaneous thought (triggered by external or internal cues) followed by a cognitive process involving the construction of multi-sensory images. The CEQ-forces cravings consists of 10 items assessing craving intensity, images, and thought intrusion. The 4 items covering imagery, scent, taste and mouth/throat sensation have been adapted into three items to better reflect the experience of craving with gambling. The CEQ is a 10-items questionnaire that measures the intensity craving (i.e. the irrepressible urge to consume a substance) in the last 7 days. Each item is rated from 0 (Not at all) to 10 (Extremely). Total scores summarise strength of craving, which can range between 0 and 100. The higher the score, the more the craving felt by the participant is considered intense.

Change in Readiness to Change Questionnaire (RCQ)-Gamblers

Time Frame: in the last 90 days of admission, 6,12 and 18 months post-admission (The first admission is anticipated for april 2023 and the last in march 2024)

Outcome measure for Gamblers The RCQ is a 12-item instrument used for identifying the "stage of change" of someone having an addiction problem, which are : precontemplation (PC), contemplation (C) and action (A). Questions assess the degree of motivation to change substance use and/or gambling habits. The respondent answers with -2 (Strongly disagree), -1 (Disagree), 0 (Unsure), +1 (Agree), +2 (Strongly Agree). The item score for each scale (PC, C and A) is summed, meaning the total score should be within the range -8 to +8. The scale with the highest score is the one that determines the stage of motivation to change.

Change in Readiness Ruler tool-Gambler

Time Frame: in the last seven days of admission, 6,12 and 18 months post-admission (The first admission is anticipated for april 2023 and the last in march 2024)

Outcome measure for Gamblers The instrument has two items, one to estimate how important people with problematic use feel it is to change their behaviors, and another to estimate how capable they feel they are of changing their behaviors, reflecting their sense of competence in changing their behavior or their perceived ability to change.Responses are distributed along a continuum from 0 to 10 where "0" represents "not at all," "5" means "moderately" and "10" represents "extremely." Higher the score is for each scale, respectively, the higher the level of importance and the level of confidence about making this change.
