The reliability and stability of self-reports of licit and illicit drug use are estimated using longitudinal data, and found to be rather high. An apparent inconsistency in reporting (less use over a 12-month period than would be expected based on use reported over a 30-day period) is examined (1) for association with personal characteristics and (2) for individual consistency over time. Neither individual consistency nor significant associations are found, although there appears to be a tendency for discrepant reporting of marijuana and alcohol use to be correlated within time. The data used are from the Monitoring the Future project, an ongoing nationwide study of high school seniors, with follow-up surveys after graduation.
利用纵向数据估计合法和非法药物使用自我报告的可靠性和稳定性，结果发现相当高。对报告中一个明显的不一致之处（即12个月期间的使用量低于根据30天期间报告的使用量预期的使用量）进行了研究：（1）与个人特征的关联，以及（2）随时间的个体一致性。尽管在大麻和酒精使用的差异报告在时间上似乎存在相关趋势，但未发现个体一致性或显著关联。所使用的数据来自“未来监测”项目，这是一项正在进行的针对高中高年级学生的全国性研究，毕业后会进行跟踪调查。
