OBJECTIVES/BACKGROUND: Ecstasy/polydrug users have exhibited deficits in executive functioning in laboratory tests. We sought to extend these findings by investigating the extent to which ecstasy/polydrug users manifest executive deficits in everyday life.
Forty-two current ecstasy/polydrug users, 18 previous (abstinent for at least 6 months) ecstasy/polydrug users, and 50 non-users of ecstasy (including both non-users of any illicit drug and some cannabis-only users) completed the self-report Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) measure.
Current ecstasy/polydrug users performed significantly worse than previous users and non-users on subscales measuring inhibition, self-monitoring, initiating action, working memory, planning, monitoring ongoing task performance, and organizational ability. Previous ecstasy/polydrug users did not differ significantly from non-users. In regression analyses, although the current frequency of ecstasy use accounted for statistically significant unique variance on 3 of the 9 BRIEF-A subscales, daily cigarette consumption was the main predictor in 6 of the subscales.
Current ecstasy/polydrug users report more executive dysfunction than do previous users and non-users. This finding appears to relate to some aspect of ongoing ecstasy use and seems largely unrelated to the use of other illicit drugs. An unexpected finding was the association of current nicotine consumption with executive dysfunction.
目的/背景:摇头丸/多种药物使用者在实验室测试中表现出执行功能缺陷。我们试图通过调查摇头丸/多种药物使用者在日常生活中表现出执行功能缺陷的程度来扩展这些发现。
42名当前摇头丸/多种药物使用者、18名既往(已戒除至少6个月)摇头丸/多种药物使用者以及50名非摇头丸使用者(包括任何非法药物的非使用者和一些仅使用大麻的使用者)完成了自我报告的成人版执行功能行为评定量表(BRIEF-A)测量。
在测量抑制、自我监控、启动行动、工作记忆、计划、监控正在进行的任务表现和组织能力的分量表上,当前摇头丸/多种药物使用者的表现明显比既往使用者和非使用者差。既往摇头丸/多种药物使用者与非使用者没有显著差异。在回归分析中,虽然当前摇头丸使用频率在9个BRIEF-A分量表中的3个上占统计显著的独特方差,但每日香烟消费量是6个分量表中的主要预测因素。
当前摇头丸/多种药物使用者报告的执行功能障碍比既往使用者和非使用者更多。这一发现似乎与正在进行的摇头丸使用的某些方面有关,而且似乎在很大程度上与其他非法药物的使用无关。一个意外的发现是当前尼古丁消费与执行功能障碍之间的关联。
