Significant negative consequences can result from involvement in gambling activities. In the following sections, we discuss the gambling resources available to mitigate the risk of developing gambling-related harm and to ameliorate such harms after they occur, as well as the factors relevant to their successful implementation: service utilization, protection, prevention and harm reduction, and interventions.
The strength of the evidence for the benefits of gambling resources varies considerably. The majority of evidence to date consists of evaluations of mutual support, self-help, and treatment. Although gaps remain, a number of reviews support the effectiveness of some of these resources (e.g., Stea & Hodgins, 2011). In contrast, there is less evidence for the impact of harm-reduction and prevention programming; it is also less cohesive.
