User Perceptions of Responsible Gambling Messages as Nudges for Gambling Safety

Nudges are subtle interventions designed to influence user behavior without restricting choice. Responsible gambling messages (RGMs) exemplify such nudges by encouraging safer decision-making in gambling environments. Prior research has examined how pop-up messages influence gambling behavior in experimental settings and has explored the design of effective slogan messages. However, little is known about how different types of RGMs shape users’ real-world gambling behavior and safety. To address this gap, we apply a nudging perspective to examine how RGMs support gambling safety throughout gamblers’ decision-making journey. We conducted semi-structured interviews with 22 gamblers and found that participants were generally aware of RGMs, yet some misunderstood their intended purpose. Participants perceived the safety impact of RGMs as reflected in both attitudinal and behavioral dimensions. We further discuss users’ message reception practices and the effectiveness of RGMs as nudges, and conclude with design implications for promoting gambling safety.
