Given ecstasy's (MDMA) potential serotonergic neurotoxicity, it is plausible that regular ecstasy users would have an elevated prevalence of behavioral executive dysfunction or mood symptoms. However, recent studies have found that the relationship between ecstasy use and psychological symptoms was no longer significant after controlling for marijuana use (e.g., Morgan et al., 2002). The goal of the present study was to examine the relationship between ecstasy exposure and self-reported executive functioning and psychological symptoms after controlling for gender, ethnicity, and other drug use.
Data were collected from 65 men and women with a wide range of ecstasy use (including 17 marijuana-using controls). Participants were administered the Frontal Systems Behavioral Scale, State-Trait Anxiety Inventory for adults, and the Beck Depression Inventory-2nd edition.
Although 19-63% of the ecstasy users demonstrated clinically elevated psychological symptoms, frequency of ecstasy use did not predict the psychological symptoms. No gender differences or interactions were observed.
These results revealed that, although ecstasy users demonstrate elevated levels of psychological symptoms and executive dysfunction, these symptoms are not statistically associated with their ecstasy consumption. Instead, other drug use (alcohol, marijuana, opioids, and inhalants) significantly predict psychological symptoms in this sample of polydrug users.
鉴于摇头丸(MDMA)具有潜在的血清素能神经毒性,经常使用摇头丸的人出现行为执行功能障碍或情绪症状的患病率可能会升高。然而,最近的研究发现,在控制了大麻使用情况后(例如,Morgan等人,2002年),使用摇头丸与心理症状之间的关系不再显著。本研究的目的是在控制性别、种族和其他药物使用情况后,考察接触摇头丸与自我报告的执行功能及心理症状之间的关系。
收集了65名男女的数据,他们使用摇头丸的情况各不相同(包括17名使用大麻的对照者)。对参与者进行了额叶系统行为量表、成人状态-特质焦虑量表和贝克抑郁量表第二版的测试。
尽管19%至63%的摇头丸使用者表现出临床上心理症状升高,但摇头丸的使用频率并不能预测心理症状。未观察到性别差异或交互作用。
这些结果表明,尽管摇头丸使用者表现出较高水平的心理症状和执行功能障碍,但这些症状与他们使用摇头丸在统计学上并无关联。相反,在这个多药滥用者样本中,其他药物使用(酒精、大麻、阿片类药物和吸入剂)显著预测心理症状。
