Brief summary

The goal of this pilot study is to learn if Acceptance and Commitment Therapy (ACT) works to treat Problem Gambling in young adults.The main questions it aims to answer are: * Does ACT therapy improve health and gambling behavior? * Is an 8-week online group therapy format viable for youth with gambling problems? 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

Detailed description

After being informed about the study, all patients giving written informed consent will be assessed to determine eligibility for study entry. Patients who meet eligibility requirements will receive psychological intervention consisting in an 8-session group on line-delivered ACT-based treatment. The participants will be assessed through self-report instruments before and after treatment and at 3 and 6 months follow-up. The pilot study will not include a control group.

Design outcomes

Primary

MeasureTime frameDescription
Change in Problem Gambling Severity Index (PGSI)Change from Baseline severity of problem gambling at 8 monthsThe 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.

Secondary

MeasureTime frameDescription
Change in General Health Questionnaire (GHQ-12)Change from Baseline psychological distress and perceived general health at 8 monthsThe 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.
Change in the Comprehensive ACT Process Assessment Questionnaire (CompACT)Change from Baseline psychological flexibility at 8 monthsThe 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.
Change in Values Living Questionnaire (VLQ)Change from Baseline value-behavior alignment at 8 monthsThe 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.
Change in Difficulties in Emotion Regulation Scale (DERS-28)Change from Baseline emotion regulation at 8 monthsThe 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.
Change in Gambling-Related Experiential Avoidance scaleChange from Baseline Experiential Avoidance at 8 monthsA weekly subjective scale assessing the extent to which the participant has attempted to avoid gambling-related emotions, thoughts, or internal situations. Higher scores indicate greater experiential avoidance and less flexibility.
Change in the frequency of self-reported gambling behaviorsChange from Baseline gambling behaviors at 8 monthsDaily self-monitoring in which the participant indicates whether they gambled, the duration, type of gambling, emotions before, during, and after, and perceived function of the behavior. Weekly frequency of gambling episodes will be analyzed. Higher frequency is interpreted as worse clinical outcome.
Change in the frequency of committed actionsChange from Baseline committed actions at 8 monthsSelf-monitoring of the frequency with which the participant has acted in accordance with their personal values during moments of desire to gamble. This is considered a positive behavioral indicator of change.
Change in Gambling-Related Emotional Distress ScaleChange from Baseline gambling-related distress at 8 monthsA weekly subjective scale assessing the frequency and intensity of emotional distress associated with gambling behavior using Likert scales ranging from 0 to 5. Higher scores reflect greater gambling-related distress.
