Aims: The aim of this study is to assess the impact of the cap level on total consumption and a range of variables including negative consequences. Design, Setting, and Participants: Cross sectional survey in Australia with 2,020 Australians aged 16 and over.Measures: Participants completed a detailed survey on their alcohol consumption with no methodological limit on consumption.Findings: Setting a cap on high levels of consumption can significantly decrease the mean level of consumption. While the relationship between consumption and related variables do not change significantly, the relationship with negative consequences strengthens as the cap lowers, and the relationship with purchases decreases for uncapped data and data with low caps, providing some guidance on where a cap would be best placed.Conclusions: Consideration of where to set a maximum daily consumption level in survey research should be not only based on what could be feasibly consumed, but also on the point at which a very high reported consumption level is more likely to have been reported in error than as a reflection of reality. Checking the relationship between consumption and related variables, with different caps applied before selecting a capping level, is recommended.

在澳大利亚调查研究中设定每日最大平均饮酒量上限

目的：本研究的目的是评估上限水平对总消费的影响以及包括负面后果在内的一系列变量。设计、设置和参与者：在澳大利亚对 2,020 名 16 岁及以上的澳大利亚人进行的横断面调查。措施：参与者完成了一项关于酒精消费的详细调查，对饮酒没有方法上的限制。结果：对高水平的消费设定上限可以显着降低平均消费水平。虽然消费和相关变量之间的关系没有显着变化，但随着上限的降低，与负面后果的关系会加强，并且对于无上限数据和低上限数据与购买的关系会降低，从而为最适合设置上限的位置提供一些指导.结论：在调查研究中，考虑在何处设定最高每日消费水平，不仅应基于可行的消费量，还应基于报告的非常高的消费水平更可能被错误报告的点，而不是现实的反映。建议在选择上限水平之前检查消费和相关变量之间的关系，并应用不同的上限。
