The purpose of this study was to describe and assess the utility of an Internet-based survey method for characterizing the alcohol consumption of college students. After extensive pilot research, a random sample of 1910 students aged 16-29 years was invited to complete a questionnaire, consisting of a series of web-pages linked to a relational database on a secure web-site. A branch structure allowed for tailoring of survey items by age and gender. The students received up to nine contacts, including a pre-notice letter with a token gift and an e-mail invitation (Phase 1), a reminder letter and e-mail message (Phase 2), and then telephone reminders and replacement access codes (Phase 3). Non-computer-users were offered a pen-and-paper alternative, making this a mixed-mode survey. The overall response to the survey was 82% (n = 1564). The median completion time was 16.7 min. Participants' comments showed high levels of satisfaction with the survey. Comparison of web (n = 1501) versus pen-and-paper completions (n = 63) revealed no modality effects. Technical problems addressed during the course of implementation included web-browser-operating system incompatibilities, and periodic network errors, although these resulted in little lost participation. Internet-based surveys are feasible for college student research and with carefully managed recruitment, can yield a high response.
本研究的目的是描述和评估一种基于互联网的调查方法在描述大学生饮酒情况方面的效用。经过广泛的预研究，邀请了1910名年龄在16 - 29岁的学生作为随机样本，让他们完成一份问卷，该问卷由一系列链接到安全网站上关系数据库的网页组成。分支结构允许根据年龄和性别定制调查项目。学生们收到多达九次联系，包括一封带有小礼品的预告信和一封电子邮件邀请（第一阶段）、一封提醒信和一封电子邮件（第二阶段），然后是电话提醒和替换访问代码（第三阶段）。非计算机用户可以选择纸笔作答，这使得本次调查成为一种混合模式调查。该调查的总体回复率为82%（n = 1564）。平均完成时间为16.7分钟。参与者的评论显示对该调查满意度很高。对网络作答（n = 1501）和纸笔作答（n = 63）的比较显示没有模式效应。实施过程中解决的技术问题包括网络浏览器与操作系统不兼容以及周期性网络错误，不过这些导致的参与度损失很小。基于互联网的调查对于大学生研究是可行的，并且通过精心管理招募工作，可以获得很高的回复率。
