Brief Summary

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.

Study Groups

No Incentive

The "No Incentive" arm will participate in two surveys-including questions about beliefs about therapy and willingness to pay for therapy, gambling behavior, and well-being-at the baseline and at the end (four months after the first survey). The arm will have access to free cognitive behavioral therapy through Kindbridge Behavioral Health, but will not receive a monetary incentive to undergo therapy.

Group Type: NO_INTERVENTION

No interventions assigned to this group

Fixed Incentive

The "Fixed Incentive" arm will participate in two surveys-including questions about beliefs about therapy and willingness to pay for therapy, gambling behavior, and well-being-at the baseline and at the end (four months after the first survey). The arm will have access to free cognitive behavioral therapy through Kindbridge Behavioral Health and will be offered a modest monetary incentive to undergo therapy. The incentive will be in form of an electronic gift card. The amount of money offered as an incentive will not depend on the participants' survey replies.

Group Type: EXPERIMENTAL

Monetary Incentive for Take-Up of Cognitive Behavioral Therapy

Intervention Type: BEHAVIORAL

Both treatment arms will be offered a monetary incentive (in form of a retail gift card) for undergoing a certain number of CBT sessions.

Payment According to Multiple Price List Choices

The "Multiple Price List" arm will participate in two surveys-including questions about beliefs about therapy and willingness to pay for therapy, gambling behavior, and well-being-at the baseline and at the end. The arm will have access to free cognitive behavioral therapy through Kindbridge Behavioral Health and might be offered a modest monetary incentive to undergo therapy. More specifically, for all arms, the surveys will include a multiple price list to gauge willingness to pay for CBT. For this "multiple price list" arm, one of the rows from the multiple price list will be (randomly) picked and implemented. Depending on what the participant answered in the randomly picked row, they will either receive an unconditional payment or a payment conditional on undergoing CBT. In either case, the payment will be in form of an electronic gift card.
