This study was carried out to ascertain the validity and reliability of data generated through an internationally developed self-administered questionnaire. Data were collected from two student populations in which prevalence of drug use was known (high and low prevalence rates) and information obtained from the questionnaire checked through personal interview. The questionnaire covered both demographic characteristics and drug use items. A total of 474 students were tested and 335 students (70.7 per cent) retested. Although percentages of missing data and inconsistent responses were high, the questionnaire appeared valid and reliable when analysed on a group basis. It was less reliable on an individual basis. In conclusion, it is considered that with minor modifications the questionnaire can be used in the populations studied with enough confidence in validity and reliability to allow comparisons.
本研究旨在确定通过国际开发的自填式问卷所生成数据的有效性和可靠性。从两个已知吸毒流行率(高流行率和低流行率)的学生群体中收集数据,并通过个人访谈对问卷所获信息进行核对。该问卷涵盖人口统计学特征和吸毒相关项目。共对474名学生进行了测试,335名学生(70.7%)进行了重新测试。尽管缺失数据和不一致回答的百分比很高,但在群体基础上进行分析时,该问卷似乎具有有效性和可靠性。在个体基础上则可靠性较低。总之,认为对问卷稍作修改后,可在研究人群中使用,其有效性和可靠性足以令人放心地进行比较。
