Study summary

Purpose and significance A brief self-directed online personalised feedback intervention was developed for the UK context designed to prevent, reduce, and address gambling harm. The intervention, which also comes in a paper format, comprises of normative feedback and personalised information on the risk of gambling above lower-risk gambling guidelines. The content is based on recent work adapting the Canadian lower-risk gambling guidelines to the UK context. The purpose of this exploratory research is to conduct the first randomised controlled trial of this intervention. Further, given the increased prevalence of online gambling, the project will target this at-risk population.

Rationale This project will generate participant feedback on the intervention important to improve its utility. The project will also produce publishable findings on the intervention's efficacy. This evaluation provides a necessary first step towards the wide-spread implementation of this free-of-charge intervention in the UK.

Methodology First, using methods developed in our previous research, we will rapidly recruit 926 online gambling participants with moderate or problem gambling from an existing online panel of UK residents. These participants will be randomised to receive the self-directed online intervention or assigned to a no intervention control group. Participants will be followed-up up at one- and three-months to provide detailed feedback on their impressions of the intervention (and what further modifications are needed) and to assess the short-term impact of the intervention on gambling frequency and harm.

Potential implications of the proposed research The intervention can be accessed at any time of the day and allow the delivery of help without requiring face-to-face contact. Online interventions also have the potential to promote reductions in social inequalities through reducing barriers to accessible care. At present, there appears to be no UK online at-risk gambling intervention that is publicly available.
