SUMMARY
This pilot study reports on the initial usage of an online personalized feedback screener for problem gamblers. The Check Your Gambling screener (CYG; www.CheckYourGambling.net) is an online version of a paper and pencil screener that had shown some promise in an initial evaluation to promote short-term reductions in gambling behaviour. The online CYG screener was linked to two existing Web pages for gambling in Ontario, Canada-the Ontario Problem Gambling Helpline (OPGH) Web page and ProblemGambling.ca. While more participants used the ProblemGambling.ca (n = 730) version than the OPGH version (n = 591), the OPGH version appeared to be more targeted, as almost all of the participants using this Web site were Canadian (and the personalized feedback of the current version of the CYG is generated using Canadian norms). More work is needed to establish whether the online CYG screener can motivate reductions in gambling among participants or motivate treatment-seeking in those requiring assistance in addressing problematic gambling behviour.
