Study Description

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).

Condition or disease	Intervention/treatment	Phase
Gambling Disorder; Substance Use Disorders	Behavioral: Integrative Couple Treatment for Addiction (ICT-A); Behavioral: Treatment individual as usually offered	Not Applicable

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).

Arms and Interventions

Arm	Intervention/treatment
Experimental: Integrative Couple Treatment for Addiction (ICT-A); Inspired by the "Alcohol Behavior Couple Therapy" from Epstein & McCrady, the ICT-A will be offered over 12 to 16 sessions of 90 minutes. Typically, approximately the first half of each session is dedicated to GD/SUD problems,in a predominantly cognitive behavioral model. In the second part of each session, the clinician will help the couple to improve their communication,to reduce the reinforcements (non-voluntary) of the behaviors of GD/SUD and to increase marital pleasure situations incompatible with the use of GD/SUD.Particular attention will also be paid to feelings of betrayal and interpersonal attacks to restore trust. Plus,they will received a sefl-care guide.	Behavioral: Integrative Couple Treatment for Addiction (ICT-A); Couple-based intervention called Integrative Couple Treatment for Addiction (ICT-A).; Other Name: Couple therapy
Active Comparator: Individual treatment as usually offered; The usual treatment control group will receive individual treatment as already offered by the specialized centres in addiction. For the person with GD/SUD, this treatment consists of 12 to 16 individual cognitive-behavioral sessions of 60 minutes. In general, the intervention aims to secure financial assets, awareness of erroneous thoughts and improvement of alternative skills to gambling in order to meet the normal demands of psychic and relational life. People undergoing this intervention will receive a self-care guide. As for the partners randomized in this intervention, they will receive the services that are usually offered to members of the entourage of a person with GD/SUD. In groups or individually, these services are generally aimed at improving the partner's well-being and relationship with their spouse, which includes information about GD/SUD and the recovery process.	Behavioral: Treatment individual as usually offered; Individual-based treatment as usually offer by the specialized centres in addiction.; Other Name: Treatment as usual (TAU)

Primary Outcome Measures :

1. 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).

   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 the gambler's habits 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.

   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).

4. Change in Negative Gambling/Using Consequences-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) ]

   This short questionnaire of 7 items assesses to what extent the respondent considers his gambling/using habits in the last 3 months have harmed various aspects of his life (financial, living conditions, marital, physical health, professional life, social, legal and family).

   Participants are asked to respond on a scale where "0" corresponds to "not at all" or "never", while "10" corresponds to "extremely" or "always".

   To compute a total score, all item' score are summed. The total score ranges from 0 to 70.The higher the score, the more it indicates that the person is experiencing negative impacts due to their GD/SUD.

5. Change in Negative Gambling/Using Consequences-Partner [ 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 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.

   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.

   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.

10. 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
