The concurrent validity of questionnaires in population studies on drug use was tested by comparing information from registers and interviews in two populations of young people from Gothenburg. The questionnaire items' sensitivity and specificity according to criteria and their capacity for prediction of drug use and no drug use and correct classification were calculated. Considering criteria weaknesses and other sources of errors, the validity of the questionnaire items was good. This conclusion is basic to longitudinal population studies which aim at clarifying the prognosis of drug abuse among young people.
通过比较哥德堡两个年轻人群体中登记信息和访谈信息，对药物使用人群研究中问卷的同时效度进行了测试。根据标准计算了问卷项目的敏感性、特异性及其预测药物使用和未使用药物的能力以及正确分类情况。考虑到标准的弱点和其他误差来源，问卷项目的效度良好。这一结论对于旨在阐明年轻人药物滥用预后情况的纵向人群研究至关重要。
