Problem gambling can involve many different patterns of gambling behaviours. In this study, the researchers analyzed gambling behaviour patterns to identify subtypes of gambling that might be problem gambling. The researchers used behavioural tracking data from 658,028 people who had gambled with Danske Spil, a state-owned Danish gambling operator. The results were then validated using a second dataset involving 619,441 people.
The researchers identified seven distinct gambling profiles that differed in intensity, product type, spending patterns, and responses to wins and losses. Some profiles reflected high overall gambling involvement and escalating money deposits. On the other hand, others reflected increased wagering after large wins or losses. Not all high-intensity gambling patterns showed clear signs of harm, suggesting that high spending alone might not indicate increased risk. Moreover, people with the same profile still somewhat differed from each other.
The results suggest that problem gambling may involve multiple different combinations of behaviours. These findings can inform tailored approaches to problem gambling detection and prevention.
