School surveys have become the most common method for determining the general level of tobacco, alcohol and illicit drug use among adolescents in a large number of countries. The two most commonly applied field procedures in school surveys are teachers' and researchers' administration of questionnaires. The impact of the difference between these two modes of administration has not been determined, although it has been argued that central involvement of teachers in data collection may decrease the perceived anonymity of the survey among students, and should thus be avoided. In a split-half random sample of 3017 urban, Icelandic 16-20-year-old students, no statistically significant differences were found in reported use of licit or illicit drugs, nor in the stated willingness to be honest between these two modes of administration. These results suggest that when students return their responses in sealed envelopes, the two modes of administration produce equally valid results.
在许多国家，学校调查已成为确定青少年烟草、酒精和非法药物使用总体水平的最常用方法。学校调查中最常用的两种实地调查方法是教师和研究人员发放问卷。尽管有人认为教师参与数据收集可能会降低学生对调查匿名性的感知，因此应避免，但这两种发放方式之间差异的影响尚未确定。在对3017名16至20岁的冰岛城市学生进行的对半随机抽样中，在合法或非法药物的报告使用情况以及这两种发放方式下学生表示诚实作答的意愿方面，均未发现统计学上的显著差异。这些结果表明，当学生将答卷装在密封信封中交回时，这两种发放方式会产生同样有效的结果。
