: To assess the agreement between three recall periods for self-reported drug use using a 24-hour recall period as reference.
: Participants were allocated into three groups with different recall periods of 7, 14 and 30 days and were interviewed at two different times. A 24-hour recall questionnaire was answered during the first interview, and a questionnaire on drug use over the different recall periods tested was answered during the second interview. The agreement between the questionnaires was evaluated using percent agreement and kappa.
: For continuous drugs, percent agreement varied between 92 and 99% and kappa varied between 0.71 and 0.97 for three periods tested. For drugs of occasional use, percent agreement varied between 63 and 81% and kappa varied between 0.27 and 0.52. The prevalence of drugs, particularly those of occasional use, increases with time.
: The high level of agreement between the three recall periods suggests that all of them are valid for the investigation of drugs of continuous use.
以24小时回忆期为参照，评估自我报告药物使用情况的三种回忆期之间的一致性。
将参与者分为三组，回忆期分别为7天、14天和30天，并在两个不同时间进行访谈。在第一次访谈中回答一份24小时回忆问卷，在第二次访谈中回答一份关于所测试不同回忆期内药物使用情况的问卷。使用百分比一致性和kappa系数评估问卷之间的一致性。
对于持续性药物，在测试的三个时期中，百分比一致性在92%至99%之间，kappa系数在0.71至0.97之间。对于偶尔使用的药物，百分比一致性在63%至81%之间，kappa系数在0.27至0.52之间。药物的流行率，尤其是偶尔使用的药物，随时间增加。
三种回忆期之间的高度一致性表明，它们对于调查持续性使用的药物均有效。
