Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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
