This study examined the extent to which people with moderate-risk and problem gambling accounted for a greater amount of spending on different gambling activities. The researchers examined data collected at two timepoints for a British longitudinal study with people who gambled regularly on sports. The Problem Gambling Severity Index (PGSI) was used to assess the risk of problem gambling. At both timepoints, people with a PGSI score of 3 or higher spent substantially more on gambling than those with a score less than 3. There were some differences by activity. Casino games relied most heavily on people with a gambling problem for profits, whereas lotteries were the least dependent.
