Summary
Reducing maximum bet sizes on electronic gaming machines effectively minimizes gambling harm for problem gamblers. This structural change led to shorter play times and reduced losses, unlike other tested modifications.
Area of Science:
- Behavioral Science
- Addiction Research
- Public Health
Background:
- Problem gambling poses significant societal and individual costs.
- Electronic gaming machines (EGMs) are a primary source of gambling expenditure and harm.
- Existing harm minimization strategies for EGMs require further evaluation.
Purpose of the Study:
- To assess the efficacy of three structural modifications to EGMs as harm reduction strategies.
- To compare the impact of reduced bet size, reel spin speed, and note acceptor removal on gambling behavior.
- To differentiate effects between non-problem and probable problem gamblers.
Main Methods:
- Observational study of 779 participants in gaming venues (clubs and hotels).
- Utilized eight experimental EGMs with all combinations of three modifications.
- 210 participants played modified and unmodified machines; South Oaks Gambling Screen (SOGS) administered post-play.
Main Results:
- Problem gamblers were more likely to use high-denomination acceptors and bet over $1.
- Machines with a $1 maximum bet limit resulted in shorter play durations and lower financial losses.
- Reduced bet size also correlated with fewer wagers, less alcohol consumption, and reduced smoking.
Conclusions:
- Reducing the maximum bet level on EGMs is the most promising harm minimization strategy.
- Other tested modifications (reel spin speed, note acceptor removal) showed limited effectiveness.
- Findings suggest policy implications for EGM design to mitigate gambling-related harm.
