ABSTRACT

The prevalence of illicit drug use among high school students living in the Silesian voivodship (Poland) is estimated using either the random response techniques of forced response design or the Liu-Chow method. Respondents answer a sensitive question only with a certain probability, thus ensuring anonymity. These methods provide correct estimates of prevalence, unlike interviews based on anonymous questionnaires, which can lead to underestimate the prevalence. Compared with those obtained with anonymous questionnaires, the results obtained with the forced response method are that 10.7 times more high school students used the new psychoactive substances, 6.0 times more amphetamines, methamphetamines, and others, 3.1 times more heroin or morphine, and 1.6 times more marijuana or hashish. The Liu-Chow method provides an estimate of 10.7% of respondents who reported using new psychoactive substances, while the estimate by the anonymous questionnaire is only 1.5%. In the case of marijuana or hashish, the Liu-Chow method gives an estimate of 37.0% of users, while the estimate with anonymous questionnaires is only 22.0%.

摘要

居住在西里西亚省的高中生使用非法药物的流行率（波兰）使用强制响应设计的随机响应技术或 Liu-Chow 方法进行估计。受访者仅以一定的概率回答敏感问题，从而确保匿名。这些方法提供了对流行率的正确估计，与基于匿名问卷的访谈不同，这可能导致低估流行率。与匿名问卷调查相比，强制回答法得到的结果是，高中生使用新型精神活性物质增加了10.7倍，苯丙胺、甲基苯丙胺等增加了6.0倍，海洛因或吗啡增加了3.1倍，增加了1.6倍。更多的大麻或大麻。Liu-Chow 方法估计有 10.7% 的受访者报告使用了新的精神活性物质，而匿名问卷的估计只有1.5%。在大麻或大麻的情况下，Liu-Chow 方法对用户的估计为 37.0%，而匿名问卷的估计仅为 22.0%。
