In recent years a number of studies have used objective gambling data from online gambling operators to study gambling behavior. A few of these studies have compared gamblers’ actual gambling behavior (using account-based tracking data) with their subjective gambling behavior (using responses from survey data). The present study extended previous studies by comparing self-reported money deposited with the actual amount of money deposited. The authors were given access to an anonymized secondary dataset of 1,516 online gamblers from a European online gambling operator. After removing those who had not deposited any money in the previous 30 days, the final sample size for analysis was 639 online gamblers. The results indicated that gamblers were able to estimate fairly accurately how much money they had deposited in the past 30 days. However, the higher the amount of money deposited, the more likely gamblers underestimated the actual amount of money deposited. With respect to age and gender, there were no significant differences between male and female gamblers in their estimation biases. However, a significant age difference was found between those who overestimated and underestimated their deposits, with younger gamblers tending to overestimate their deposits. Providing feedback as to whether the gamblers overestimated or underestimated their deposits did not lead to any additional significant changes in the amount of money deposited when considering the overall reduction in deposits after self-assessment. The implications of the findings are discussed.

近年来，许多研究利用在线赌博运营商的客观赌博数据来研究赌博行为。其中一些研究将赌徒的实际赌博行为（使用基于帐户的跟踪数据）与其主观赌博行为（使用调查数据的响应）进行了比较。本研究通过比较自我报告的存款金额与实际存款金额，扩展了之前的研究。作者获得了来自欧洲在线赌博运营商的 1,516 名在线赌徒的匿名二级数据集。剔除过去30天内没有存款的人后，最终分析的样本量为639名在线赌徒。结果表明，赌徒能够相当准确地估计他们在过去 30 天内存入了多少钱。然而，存入的金额越高，赌徒就越有可能低估实际存入的金额。就年龄和性别而言，男性和女性赌徒的估计偏差没有显着差异。然而，高估和低估存款的人之间存在显着的年龄差异，年轻的赌徒往往高估他们的存款。考虑到自我评估后存款的总体减少，提供关于赌徒是否高估或低估其存款的反馈并没有导致存款金额发生任何额外的重大变化。讨论了研究结果的含义。就年龄和性别而言，男性和女性赌徒的估计偏差没有显着差异。然而，高估和低估存款的人之间存在显着的年龄差异，年轻的赌徒往往高估他们的存款。考虑到自我评估后存款的总体减少，提供关于赌徒是否高估或低估其存款的反馈并没有导致存款金额发生任何额外的重大变化。讨论了研究结果的含义。就年龄和性别而言，男性和女性赌徒的估计偏差没有显着差异。然而，高估和低估存款的人之间存在显着的年龄差异，年轻的赌徒往往高估他们的存款。考虑到自我评估后存款的总体减少，提供关于赌徒是否高估或低估其存款的反馈并没有导致存款金额发生任何额外的重大变化。讨论了研究结果的含义。年轻的赌徒往往会高估自己的存款。考虑到自我评估后存款的总体减少，提供关于赌徒是否高估或低估其存款的反馈并没有导致存款金额发生任何额外的重大变化。讨论了研究结果的含义。年轻的赌徒往往会高估自己的存款。考虑到自我评估后存款的总体减少，提供关于赌徒是否高估或低估其存款的反馈并没有导致存款金额发生任何额外的重大变化。讨论了研究结果的含义。
