Responsible gambling (RG) tools have been developed to help people gamble safely. One RG tool provides players with personalized feedback about their gambling behaviour. The researchers examined if providing personalized feedback reduced money spent gambling in a real-world setting. The researchers were given access to data involving 7134 people who gambled online in Sweden. All 7134 players had received at least one personalized message about their risky gambling behaviour. The messages helped reduce the amount of money gambled on the day players read the message. The messages also reduced money spent gambling during the seven days after the message was read. The messages were least effective for players with high-risk.
