The aim of this study is to conduct a trial to investigate the effectiveness of adding contingency management treatment (CM) to standard care cognitive behavioral therapy (CBT) for the treatment of gambling disorder to increase attendance to treatment.

The proposed research will evaluate whether CM can enhance the overall effectiveness of CBT, the most widely tested treatment for individuals with gambling disorder.

Many people with mental health conditions do not seek treatment, and it is unclear what exactly prevents people from taking up treatment. The goal of this interventional study is to learn about how people think about cognitive behavioral therapy (CBT) for gambling disorders. The main questions it aims to answer are: * Do people have incorrect beliefs about the net benefits of CBT? If yes, which beliefs are those, and how much do people underestimate or overestimate the benefits? * Is a small monetary incentive (that participants receive conditional on trying out CBT) helpful in increasing take-up of CBT? Apart from these questions, the researchers will also study how well CBT works to treat gambling disorders. Participants will be asked to complete two surveys over four months and might be offered a modest monetary incentive for doing (free) CBT if they are in the treatment group. Researchers will compare that treatment group to a control group. Participants in the control group will have access to free CBT and do the same two surveys as those in the treatment group, but will not receive the monetary incentive.
