An adjusted quantity-frequency method, with questions on occasions with heavy drinking, was used to estimate the consumption of alcohol during the last 30 days. The purpose was to analyze if it was possible to decrease the underestimation of true alcohol consumption. The questionnaire was mailed to a randomized sample of 1,500 individuals, 20-75 years of age, living in the city of Malmö, Sweden; 930 persons (64.3%) participated. Data on alcohol consumption were validated by comparison to sales of alcohol for the city of Malmö. The estimated per capita consumption of alcohol in the population was equivalent to 77.0% of the registered sale of alcohol in Malmö. By adding days with heavy drinking, the estimated weekly per capita consumption of alcohol among the alcohol consumers increased from 74.5 grams to 77.1 grams (+3.5%; p < .001). Of the alcohol consumers, 15.1% increased their reported consumption. In order to decrease even more the underestimation of the true alcohol consumption, we suggest the use of questions about any alcohol consumption that deviates from the typical consumption of each individual.
采用一种调整后的数量-频率法，通过询问重度饮酒情况来估算过去30天内的酒精消费量。目的是分析是否有可能减少对实际酒精消费量的低估。问卷被邮寄给瑞典马尔默市1500名年龄在20至75岁之间的随机抽样个体；930人（64.3%）参与了调查。通过与马尔默市酒精销售数据进行比较，对酒精消费数据进行了验证。该人群中估计的人均酒精消费量相当于马尔默市登记酒精销售量的77.0%。通过增加重度饮酒天数，酒精消费者中估计的每周人均酒精消费量从74.5克增加到77.1克（增加3.5%；p <.001）。在酒精消费者中，15.1%的人增加了他们报告的消费量。为了进一步减少对实际酒精消费量的低估，我们建议使用关于任何偏离个人典型消费量的酒精消费问题。
