Chasing refers to the escalation of betting behaviour. It is conventionally seen when losing but can also be seen after wins. Diagnostic and screening items for gambling problems describe chasing as returning 'another day' to gamble. However, gamblers may also chase within sessions, and this is particularly relevant in online gambling. This study focused on two expressions of within-session chasing: (1) increasing the bet amount, or (2) a reduced probability of quitting the session, as a function of prior losses or wins. These expressions were examined across five online gambling products: slot machines, probability games, blackjack, video poker, and roulette. Our results showed that gamblers bet more and played longer sessions after immediate losses, but they bet less and played shorter sessions when losing cumulatively. The reversed pattern in the cumulative model may be due to financial constraints. For wins, gamblers bet more after both immediate and cumulative wins, but they also played shorter sessions. Chasing patterns were qualitatively similar by game type-with limited evidence for our hypothesis that chasing would be greatest for slot machines as an established high-risk category. Overall, chasing is multi-faceted, varying across the behavioural expressions, by the immediate or cumulative timeframe of prior outcomes, and by game type.
追逐是指赌博行为的升级。通常在输钱时会出现这种情况，但也可能在赢钱后出现。赌博问题的诊断和筛查项目将追逐描述为“改天”再去赌博。然而，赌徒也可能在赌局中进行追逐，这在网上赌博中尤为相关。本研究集中讨论了两种在赌局中追逐的表现形式：（1）增加投注金额，或（2）在先前输或赢的情况下，减少退出赌局的概率。这些表现形式在五种在线赌博产品中进行了检验：老虎机、概率游戏、二十一点、视频扑克和轮盘赌。我们的研究结果表明，赌徒在即时输钱后会下更多的注，玩更长时间的赌局，但在累计输钱时，他们会下更少的注，玩更短时间的赌局。在累积模型中出现相反的模式可能是由于财务限制。对于赢钱，赌徒在即时和累积赢钱后都会下更多的注，但他们也会玩更短时间的赌局。追逐模式在游戏类型上具有相似性，我们的假设是，作为一个既定的高风险类别，老虎机会有最大的追逐行为，这一假设得到了有限的证据支持。总的来说，追逐是多方面的，它会根据即时或累积的先前结果时间框架，以及游戏类型而有所不同。
