Despite the widespread use of cannabis among young people, little research attention has been given to the development of psychometrically sound measures specific to cannabis related problems in this group. The aim of this study was to explore the reliability, validity and factor structure of a multi-dimensional measure of cannabis-related problems among adolescents. The Adolescent Cannabis Problems Questionnaire (CPQ-A) was developed as an assessment tool and treatment outcome measure. A stratified sample of 100 young people (aged 14-18 years) who had used cannabis in the past 90 days were administered the CPQ-A on two occasions 1 week apart. Exploratory factor analysis revealed three factors accounting for 63% of total variance with alpha coefficients of 0.88, 0.72 and 0.73. The CPQ-A was reliable with test-retest correlation for the total CPQ-A being 0.91. CPQ-A score correlated significantly with frequency of cannabis use and number of DSM-IV dependence criteria reported. The findings show promise for the CPQ-A as a reliable, valid and potentially clinically useful measure of cannabis related problems among young people.
尽管大麻在年轻人中广泛使用，但针对该群体大麻相关问题的标准化心理测量工具的开发却很少受到研究关注。本研究旨在探讨青少年大麻相关问题多维度测量工具的信度、效度和因子结构。青少年大麻问题问卷（CPQ-A）作为一种评估工具和治疗效果测量工具而开发。对100名在过去90天内使用过大麻的14至18岁年轻人进行分层抽样，在相隔1周的两个时间点对其进行CPQ-A测试。探索性因子分析揭示了三个因子，解释了总方差的63%，其α系数分别为0.88、0.72和0.73。CPQ-A具有信度，CPQ-A总分的重测信度为0.91。CPQ-A得分与大麻使用频率以及报告的DSM-IV依赖标准数量显著相关。研究结果表明，CPQ-A有望成为一种可靠、有效且可能在临床上有用的测量年轻人中与大麻相关问题的工具。
