The purpose of this study was to examine the link between gambling disorder and symptoms of sleep problems. The researchers used a subset of data collected for a previously published study. The sample was 152 young adults from Chicago, USA, who were between the ages of 18 and 29 years, and gambled at least 5 times in the past year. Overall, participants with gambling disorder had more sleep disruptions and worse sleep quality. They also tended to have higher anxiety and depressive symptoms. Participants with at-risk gambling did not differ much from those without problem gambling, except for early insomnia (i.e., difficulty falling asleep).
