The researchers investigated types of limits, strategies, and data that could be used to encourage people to gamble responsibly. The researchers interviewed experts and people in treatment for gambling disorder (GD). The experts suggested that players set money, time, and access limits to control their gambling. People with GD agreed that limits were a good idea. The experts identified seven strategies to consider when designing online interventions. People with GD had mixed feelings about these strategies. Both experts and people with GD thought that gambling data and other data sources could be helpful in encouraging players to stay in control. Some people with GD thought that collecting data through personal digital devices was too intrusive.
