Beliefs About Mental Health Treatment - Gambling Addiction Study in Colorado
A study testing Monetary Incentive for Take-Up of Cognitive Behavioral Therapy in people with Gambling Disorder and Gambling Problem, run by Stanford University.
Trial 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. Read more about this study

About this study
Official title: The Stanford Gambling Addiction Therapy Study (SGATS) in Colorado
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Monetary Incentive for Take-Up of Cognitive Behavioral TherapyBehavioural
Both treatment arms will be offered a monetary incentive (in form of a retail gift card) for undergoing a certain number of CBT sessions.
| Study group | Role | What they receive |
|---|---|---|
| No Incentive | No intervention | 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. |
| Fixed Incentive | Experimental | 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. Receives: Behavioral: Monetary Incentive for Take-Up of Cognitive Behavioral Therapy |
| Payment According to Multiple Price List Choices | Experimental | 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. Receives: Behavioral: Monetary Incentive for Take-Up of Cognitive Behavioral Therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Willingness to Pay for CBT
Change in participants' willingness to pay (in USD; elicited through multiple price lists) for CBT from baseline to follow-up survey.
Measured: Baseline and 4 months
Change in Beliefs about CBT
Change in participants' beliefs about therapy (such as effectiveness, unpleasantness, stigma, etc.) will between baseline and follow-up survey (4 months after baseline).
Measured: Baseline and 4 months
Attendance of CBT sessions
Dates and number of CBT sessions participants attend (as long as they are with Kindbridge Behavioral Health) between baseline survey and follow-up survey (afer 4 months).
Measured: 4 months
Change in Gambling Consumption
Amount wagered (in USD) in online and offline gambling by participants over the last month. Difference between stated amount at baseline and stated amount in follow-up survey.
Measured: Baseline and 4 months
Change in Subjective Well-Being
Change in measure of participants' wellbeing from baseline to follow-up (at four months), computed using Likert scale style questions about feeling happy/depressed/satisfied/anxious/etc. Answers are on a seven-point scale from "strongly disagree" through "neutral" to "strongly agree." Points for each question are coded such that more positive answers get more points (so from most negative to most positive, the points -1, -2/3, -1/3, 0, 1/3, 2/3, 1 are awarded) and subjective well-being is the sum of all points.
Measured: Baseline and 4 months
