This study compared the effects of an online self-management program and an in-person educational workshop for people enrolled in voluntary self-exclusion (VSE). Only 30–35% of participants completed their assigned program. Both programs worked equally well. Participants reported fewer gambling problems over time. Those who still gambled spent less money and gambled less frequently. But, there was evidence that many participants’ gambling started to increase again after 12 months. Most people rated the online program positively, but thought that it could be improved in some areas. These included being more interactive, adding more media variety, and making it more stimulating.
