About this trial

The goal of this randomized clinical trial is to study if Acceptance and Commitment Therapy (ACT) is effective to treat Problem Gambling in young adults.The main questions it aims to answer are:

* Does ACT therapy improve health and gambling behavior? * Are the clinical improvements of youth with gambling disorder receiving ACT-based intervention significantly greater than the clinical improvements of youth with gambling disorder on the waiting list?

Researchers will assess whether changes in health, gambling behavior, and other psychological variables are observed after eight weeks of therapy.

Participants will:

* Attend weekly online group sessions for 8 weeks * Learn new tools that they will put into practice after the sessions * Be required to complete evaluation questionnaires before and after the intervention and at the 3- and 6-month follow-up

Trial outcomes

Primary outcomes

1

Change in Problem Gambling Severity Index (PGSI)

The PGSI is a 9-item, 4-point Likert-format self-report scale (0 = never, 3 = almost always) that assesses the severity of problem gambling. Scores range from 0 to 27. A score of 8 or higher is considered indicative of problem gambling. Higher scores indicate greater severity of the disorder.

Time frame
Change from Baseline severity of problem gambling at 8 months

Secondary outcomes

1

Change in Difficulties in Emotion Regulation Scale (DERS-28)

he DERS-28 is a 28-item questionnaire with a 5-point Likert format (1 = almost never, 5 = almost always) that assesses difficulties in emotion regulation. It consists of six subscales: emotional nonacceptance, difficulty achieving goals, impulsivity, emotional awareness, limited strategies, and emotional clarity. Higher scores indicate greater difficulties in emotional regulation and worse clinical outcomes.

Time frame
Change from Baseline emotion regulation at 8 months
2

Change in General Health Questionnaire (GHQ-12)

The GHQ-12 is a 12-item self-report questionnaire designed to detect general psychological symptoms. It is answered on a 4-point Likert-type scale. Higher scores reflect greater psychological distress and poorer perceived general health.

Time frame
Change from Baseline psychological distress and perceived general health at 8 months
3

Change in the Comprehensive ACT Process Assessment Questionnaire (CompACT)

The CompACT is a 23-item, 7-point Likert-format scale (0 = not at all true, 6 = completely true) that assesses psychological flexibility, a core process of Acceptance and Commitment Therapy. It includes three subscales: openness to experience, awareness, and committed action. Higher scores reflect greater psychological flexibility.

Time frame
Change from Baseline psychological flexibility at 8 months
4

Change in Values Living Questionnaire (VLQ)

The Valued Living Questionnaire assesses the degree of perceived importance and consistency of action directed toward personal values in 10 life domains (family, work, health, leisure, etc.). Each item is scored from 1 to 10. A composite index of discrepancy between importance and action is calculated. Higher scores indicate less value-behavior alignment.

Time frame
Change from Baseline value-behavior alignment at 8 months
