Sports betting addiction affects a small share of adults, but online and in-play formats can raise risk through psychology and product design. This page compares prevalence findings from the U.S., U.K., Ontario, Finland, and Sweden, then connects them to drivers like impulsivity and co-occurring mood disorders. You’ll also find research on what can help, including motivational interventions, CBT (in person or web-based), plus tools such as self-exclusion and pre-commitment limits.
Key Takeaways
- In the U.S. National Surveys on Drug Use and Health (NSDUH), 0.3% of adults reported past-year gambling problems (2019)

- A large observational study found that brief motivational interventions reduced gambling frequency by 23% at 3 months (2016)
- In-play bettors showed higher odds of problem gambling; U.K. study reported OR=2.3 for problem gambling among regular in-play users (2021)
- A 2017 systematic review reported that gambling disorder co-occurs with mood disorders in about 30% of cases (pooled prevalence estimate)

- In a 2016-2017 Ontario study, 2.0% of respondents screened positive for problem gambling on the PGSI (n=2,500)
- In a U.S. survey analysis, 0.3% of adults were classified as problem gamblers and 2.2% as at-risk gamblers (2019)
- In a Swedish study, betting limits reduced monthly losses by 19% among self-excluding participants compared with baseline (2018)
- Online features like continuous play increase risk; a lab study found that near-miss exposure increased urge-to-gamble ratings by 27% compared with control (2015 experimental study)
- A 2018 experiment found that using real-money skins increased betting speed by 21% versus no-skin condition
- 5.8% of adults in Great Britain who gambled on mobile were estimated to have “problem gambling” using PGSI (2018/2019).
- 2.3x higher odds of problem gambling for regular in-play users versus non-in-play users (U.K. study, 2021).
