Interventions
The content of the C4B app is designed to teach key CBT strategies to address gambling behaviors. The content targets concerns that people with gambling problems often experience (gambling debts, cognitive distortions related to gambling - for example, how unrelated events might be related to gambling outcomes). We have designed the content such that people using the app can see the pattern of progress, identify mistakes and setbacks, and learn from common experiences of people with gambling disorder
