This paper reports on the development of a new online measure of beverage-specific past week alcohol consumption (the TOT-AL), its test-retest reliability, and comparability with the face-to-face approach of ascertaining alcohol intake.
University students participating in the reliability study completed the TOT-AL twice on the same day with at least 3 h apart. Students in the comparability study attended a face-to-face interview and completed the TOT-AL on the same day, in a randomised order, at least 3 h apart.
There was a strong correlation between the repeated measurements of the TOT-AL (r=0.99; 95% CI: 0.98, 0.99) and between the units calculated by the TOT-AL and the face-to face interview (r=0.97; 95% CI: 0.95, 0.99). A high level of agreement between measurements was also observed in a Bland-Altman analysis.
The TOT-AL is a reliable, time efficient means of ascertaining alcohol intake, equivalent to that obtained face-to-face. These findings support the use of this approach to online alcohol assessment in populations with access to the Internet.
本文报告一种新的在线测量过去一周特定饮料酒精摄入量的方法（TOT-AL）的开发情况、其重测信度以及与面对面确定酒精摄入量方法的可比性。
参与信度研究的大学生在同一天内完成两次TOT-AL测量，两次测量间隔至少3小时。可比性研究中的学生参加面对面访谈，并在同一天以随机顺序完成TOT-AL测量，两次测量间隔至少3小时。
TOT-AL的重复测量之间存在强相关性（r = 0.99；95%置信区间：0.98，0.99），TOT-AL计算的单位与面对面访谈计算的单位之间也存在强相关性（r = 0.97；95%置信区间：0.95，0.99）。在Bland-Altman分析中也观察到测量之间的高度一致性。
TOT-AL是一种可靠、省时的确定酒精摄入量的方法，等同于面对面获得的结果。这些发现支持在有网络接入的人群中使用这种在线酒精评估方法。
