Trial Summary

What is the purpose of this trial?

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

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment Integrative Couple Treatment for Addiction (ICT-A) and Integrative Couple Treatment for Pathological Gambling (ICT-PG)?

Research shows that couple therapy for pathological gambling, like ICT-PG, can improve communication and support between partners, leading to better outcomes in reducing gambling behavior and preventing relapses. Additionally, similar couple therapies have been effective in treating substance use disorders, suggesting potential benefits for addiction treatment. ^{1 2 3 4 5}

Is Couples Therapy for Addiction safe for humans?

The research on Couples Therapy for Addiction, including Integrative Couple Treatment for Pathological Gambling (ICT-PG), suggests that participants generally have positive experiences and satisfaction with the treatment. There are no specific safety concerns reported in the studies, indicating it is generally safe for humans. ^{1 2 3 4 6}

How does Integrative Couple Treatment for Addiction differ from other treatments for addiction?

Integrative Couple Treatment for Addiction (ICT-A) is unique because it involves both partners in therapy, focusing on improving communication and understanding the impact of addiction on the relationship, which can help prevent relapses and support recovery more effectively than individual therapy alone. ^{1 2 3 5 7}

Eligibility Criteria

This trial is for couples where one partner has a serious gambling or substance use problem and hasn't had treatment in the last 6 months. They must have lived together for at least half a year or been in a significant relationship for two years. Partners can use substances as long as they're not also highly addicted.

Inclusion Criteria

I have been in a significant relationship for at least 6 months.

Partners can gamble, drink alcohol or use other substances as long as they are not highly addicted to gambling (CPGI≥ 8) or alcohol/substances (ASSIST ≥ 26) and if the partners present a problem to one or the other, it cannot be of moderate level for both issues (score between 3 to 7 from CPGI for gambling, score between 11 to 26 from ASSIST for alcohol, score between 4 to 26 from ASSIST for other substances)

Problem at treatment entry may be gambling or substance use, but it must reach a severity that warrants referral to specialized services (PGSI score ≥8 for GD, ASSIST score ≥26 for alcohol or other substances)

Exclusion Criteria

I have been involved in or a victim of serious domestic violence in the last year.

Disorder or serious mental health unstabilized for one of two members of the couple (History of Psychiatric Hospitalization) in the last 6 months

Scenario with strong suicidal ideation or attempt in the last 30 days or less of two members of the couple (History of Psychiatric Hospitalization)

Treatment Details

Interventions

• Integrative Couple Treatment for Addiction (ICT-A)
• Treatment individual as usually offered

Trial Overview The study compares Integrative Couple Treatment for Addiction (ICT-A) with standard individual treatment to see which is more effective for those struggling with gambling or substance addiction.

Participant Groups

Group I: Integrative Couple Treatment for Addiction (ICT-A) Experimental Treatment 1 Intervention

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.

Group II: Individual treatment as usually offered Active Control 1 Intervention

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.

Findings from Research

Couple treatment for pathological gambling (ICT-PG) was reported to provide a more positive experience for participants compared to individual treatment, with gamblers and their partners noting improved communication and support in addressing gambling issues.

Participants highlighted that couple therapy facilitated better understanding and prevention of relapse, suggesting that involving partners in treatment can enhance the effectiveness of interventions for pathological gambling.

Integrative couple treatment for pathological gambling (ICT-PG) led to greater improvements in gambling severity and individual well-being compared to individual treatment, with significant reductions in gambling cravings and erroneous beliefs about gambling.

Both treatments resulted in decreased gambling expenses, but ICT-PG was associated with better outcomes for both gamblers and their partners, including reduced depression and increased relationship satisfaction.

Pathological gambling has significant negative effects on relationships, particularly with spouses, yet most treatment models focus solely on the individual without involving family dynamics.

The proposed Adapted Couple Therapy (ACT) model, developed in collaboration with Québec clinical settings, aims to complement existing individual cognitive-behavioral treatments and may improve outcomes for gamblers by addressing relational issues, potentially reducing dropout rates and relapse.

Problem gambling (PG) is identified as a significant family issue that affects couple and family relationships, highlighting the need for therapists to understand its systemic impacts.

There is a lack of training among family therapists in addressing problem gambling, which calls for increased awareness and development of systemic-based treatments to support affected families.

Couples therapy (CCT) was found to be more effective than individual treatment-as-usual (TAU) for improving primary outcomes like alcohol use, psychiatric symptoms, and couple adjustment, with medium-to-large effect sizes in a study involving 46 participants over 8 months.

CCT also showed significant improvements in secondary outcomes such as emotion regulation and depression, indicating its potential as a comprehensive treatment for couples dealing with addiction issues.

This study will compare the effectiveness of behavioral couples therapy (BCT), which includes concerned significant others (CSOs) in treatment, against individual cognitive-behavioral therapy (CBT) for problem gambling, involving 120 couples.

It is the first research to apply BCT specifically for problem gambling, aiming to assess its impact on gambling behavior and relationship satisfaction over a 12-month period, which could provide new insights into treatment approaches.

Behavioral couples therapy (BCT) combined with individually-based therapy (IBT) significantly improved relationship satisfaction and reduced separation rates among drug-abusing women compared to IBT alone, with notable effects observed over a 1-year follow-up.

Both treatment groups showed substantial improvements in substance use outcomes, but those receiving BCT + IBT reported fewer substance-related problems, highlighting the added benefit of incorporating couples therapy in treatment for substance use disorders.
