The Effect of Chatbot Interventions on Gambling Disorder: A Systematic Review
摘要
Gambling disorder represents serious public health concern worldwide, yet many individuals with gambling-related problems remain untreated due to stigma and accessibility barriers. As digital mental health interventions expand, chatbots offer a promising alternative for facilitating therapeutic support. However, the efficacy of chatbot-delivered interventions for gambling disorder remains underexplored. This systematic review aimed to investigate the effectiveness of chatbot-based interventions in reducing gambling severity and related symptoms among adults with problematic or disordered gambling. Guided by the PRISMA protocol and the PICOS framework, eight electronic databases (Scopus, PsycINFO, Web of Science, Ovid MEDLINE, Ovid Embase, PubMed, ProQuest Dissertations & Theses Global, and IEEE Xplore) were systematically searched up to December 1, 2024. Randomized controlled trials (RCTs) involving chatbot interventions targeting gambling behavior or its secondary outcomes were considered. Of the 3744 records identified, two RCTs met the inclusion criteria. Findings indicated significant within-group reductions in gambling severity and high user engagement, but group differences were often nonsignificant. Despite promising indicators—particularly in reducing gambling symptoms and maintaining low attrition—robust evidence on chatbot-based interventions for gambling disorder is scarce. Future RCTs with larger, more diverse samples and longer follow-up periods are urgently needed to verify these pioneer outcomes and advance implementation in real-world settings.
