This study characterized chasing behaviour as the time to return to an online gambling website after a losing or a winning visit.
We analyzed a naturalistic dataset from an eCasino (PlayNow.com, the provincial platform for British Columbia, Canada), comprising 1,909,681 sessions from 15,544 individuals. Analyses distinguished sessions on slot machines, blackjack, roulette, video poker, probability games, or mixed-category sessions.
Overall, gamblers on most games returned more slowly as a function of the prior loss, and more quickly as a function of the prior win. Loss chasing intensities in blackjack, probability, video poker, and mixed sessions did not differ significantly from slot machines, but roulette was associated with shorter intervals to return (b = -0.13, p < 0.001). Similarly, win chasing did not vary across slot machines, blackjack, probability games, and video poker, but roulette (b = -0.08, p < 0.001) and mixed (b = -0.02, p = 0.009) sessions were associated with shorter intervals.
The average behavioural patterns provide limited evidence for loss chasing but clearly indicate win chasing. Although slot machines are commonly considered a high-risk product, roulette in our analyses was associated with the greatest chasing intensities.
本研究将追号行为定义为在访问在线赌博网站后，因输钱或赢钱而返回网站的时间。
我们分析了来自电子赌场（PlayNow.com，加拿大不列颠哥伦比亚省的省级平台）的自然数据集，该数据集包含 15544 名参与者的 1909681 个会话。分析将老虎机、百家乐、轮盘、视频扑克、概率游戏或混合类别会话区分开来。
总体而言，大多数游戏的赌徒在前一次损失后会更慢地返回，在前一次赢钱后会更快地返回。百家乐、概率、视频扑克和混合游戏的亏损追号强度与老虎机没有显著差异，但轮盘游戏的亏损追号强度与更短的返回间隔相关（b = -0.13，p < 0.001）。同样，赢钱追号在老虎机、百家乐、概率游戏和视频扑克之间没有差异，但轮盘游戏（b = -0.08，p < 0.001）和混合游戏（b = -0.02，p = 0.009）的赢钱追号与更短的返回间隔相关。
平均行为模式提供了有限的亏损追号证据，但清楚地表明了赢钱追号。尽管老虎机通常被认为是高风险产品，但在我们的分析中，轮盘游戏与最大的追号强度相关。
