Gambling Harm-Minimisation Tools and Their Impact on Gambling Behaviour: A Review of the Empirical Evidence

The harms accompanying disordered gambling are well documented. Additionally, there is growing attention to the harms that arise from people who gamble heavily but do not meet the criteria for a gambling disorder. Accordingly, there has been an increasing interest in the effectiveness of consumer protection tools for consumers of gambling products. Subsequently, there is a need to properly evaluate the evidence for their effectiveness. This review aimed to conduct a narrative synthesis of empirical studies to identify gaps, weaknesses, and strengths in the existing evidence for the effectiveness of harm minimisation tools available to people who gamble. This review includes studies published between January 2015 to July 2022 and comprises 55 peer-reviewed studies for final synthesis. Findings reveal that while more research is needed to examine the effectiveness of active and passive consumer protection tools, uptake of tools is low in part because users view them as tools for individuals already experiencing gambling harm as opposed to protective tools for all users. Research is needed to determine effective ways of communicating the value of consumer protection tools for gambling.
