This paper proposes and pilots a repeated random sampling method to promote the likelihood of collecting drinking data equally representative of the behavior of university students at all times through the academic year.
From October, 2016, to May, 2017, random samples of 1350 students were selected from the 39,155 undergraduate students enrolled in the fall semester at University of Houston. These students were sent an email inviting them to complete an online survey (entered into a weekly draw for a $50 gift certificate if responded).
The response rate was low (6%). Among participants who reported drinking in the last week, there was a variation as expected in the amount of drinking observed depending on the time of year (e.g., during exams).
While the sampling methods show promise, procedures would need to be implemented to substantially increase response rates before the proposed methods could be seen as an advantage over existing survey sampling procedures.
本文提出并试行一种重复随机抽样方法，以提高在整个学年收集能平等代表大学生行为的饮酒数据的可能性。
从2016年10月至2017年5月，从休斯顿大学秋季学期注册的39155名本科生中随机抽取1350名学生样本。向这些学生发送电子邮件，邀请他们完成一项在线调查（如果回复，可参加每周一次的50美元礼品券抽奖）。
回复率较低（6%）。在报告上周饮酒的参与者中，根据一年中的时间（例如考试期间），观察到的饮酒量存在预期的差异。
虽然抽样方法显示出前景，但在提议的方法被视为比现有调查抽样程序更具优势之前，需要实施相关程序以大幅提高回复率。
