摘要进行了一项抽样调查，以获得爱丁堡成年男性的自我报告酒精消费数据。两个匹配的一半样本被随机分配到电脑访谈或直接访谈中。这项研究的目的是评估在对一般人口进行实地调查时使用计算机访问技术的可行性，并确定与直接访问相比，计算机访问方法是否会显示报告的消费值大幅增加。直接访谈中报告的平均总消费与最近对这一人口子组的其他调查结果一致(Knight&Wilson，1980；Kendell等人，1982)。在电脑采访中报告的平均总消费量高出约30%，即使在控制了其他已知的影响消费的变量后，这一差异仍然非常显著。葡萄酒和烈性酒的增幅为50%，高于啤酒(25%)。这些结果表明，在酒精消费的调查测量中，已知存在的漏报偏差可以通过用计算机取代访谈者来减少。需要进一步的研究来证实这一初步发现，但该方法的潜力已经得到证明。
Summary A sample survey to obtain self-report alcohol consumption data from adult males in Edinburgh was conducted. Two matched half samples were assigned to a computer interview or a direct interview at random. The aims of the study were to assess the feasibility of using computer interviewing techniques in a field survey of the general population and also to ascertain whether the computer interview method would show a significant increase in the reported consumption values when compared with direct interview. The mean total consumption reported in the direct interviews was consistent with findings from other recent surveys of this demographic subgroup (Knight & Wilson, 1980; Kendell et al., 1982). The mean total consumption reported in the computer interviews was some 30% higher, a difference which remained highly significant even after controlling for other variables known to affect consumption. The percentage increase for wine and spirits at 50% was greater than that for beer (25%). These results suggest that the bias of underreporting known to exist in survey measurement of alcohol consumption may be reduced by replacing the interviewer by a computer. Further studies are required to substantiate this preliminary finding, but the potential of the methodology has been demonstrated.
