“Personality dimensions and psychopathological profiles of Ecstasy users
Hum Psychopharmacol Clin Exp. 2001;16(8):635-639.
Only limited information is available with respect to personality traits and the psychopathological characteristics of Ecstasy users. To shed some light on the issue, we compared a group of 43 Ecstasy consumers (made up of both experimenters, those who took 27.5 tablets in their lifetime, and abusers, those who took larger amounts of the drug) with a composite control group of 77 subjects (made up of drug-free people, cannabis users and users of illicit drugs other than Ecstasy). Three instruments were used: the Questionnaire for the Assessment of the Use of Entactogenic Drugs (to assess modalities and characteristics of Ecstasy use); the Cloninger Tridimensional Personality Questionnaire (which measures harm avoidance, reward dependence and novelty seeking) and the SCL-90 (which measures 10 different psychiatric variables). The Ecstasy consumer group subjects showed higher novelty seeking scores than the controls (p < 0.001), and Ecstasy experimenters showed lower harm avoidance scores than the abusers (p = 0.029), but values of both reward dependence and harm avoidance dimensions were associated with sex. On the SCL-90, Ecstasy users showed higher scores than the controls on the obsession-compulsion (p = 0.004), phobic anxiety (p = 0.037), psychoticism (p = 0.005) and sleep disturbances (p = 0.046) subscales. However, many of the SCL-90 subscale results were associated with sex, and only the psychoticism values seemed to suggest a clinical condition. The main finding of this study is that high novelty seeking scores are characteristic of Ecstasy consumers: The propensity to look selectively for novelties could possibly act as a predisposing factor for Ecstasy abuse itself.
