Supplementary Material for: Substance Use and Prevention Programs in Berlin’s Party Scene: Results of the SuPrA-Study

Background: Berlin is internationally known for its nightlife. In a nation-wide and Europe-wide comparison, the use of legal and illegal substances is comparatively higher in Berlin than in other similar cities. However, few data exist about the drug use in the party scene. Objective: This study aims to assess the sociodemographic characteristics of Berlin’s party scene and its patterns of substance use as well as expectations towards prevention in order to derive appropriate preventive measures. Methods: Using questionnaires, both online (n = 674) and in the field (n = 203), a total of 877 people of the Berlin party scene were interviewed. The questionnaires ascertained the demographic information of the participants and patterns of substance use in the scene. It also collected the demand for consulting services and personal assessments on the usefulness of prospective and existing prevention programs and offers. Results: The study participants were 29 years old (SD 7.5); 43% were female. Alcohol is the most common substance in the party scene, followed by cannabis, MDMA/Ecstasy, amphetamine, cocaine, and ketamine. In this particular cohort, methamphetamine and “legal highs” did not play a major role. The most demanded preventive measure was more education about drugs and the so called drug-checking. Conclusions: Prevention in this area is both needed and requested, and an expansion of the existing programs (e.g., by so far politically controversial drug-checking) should be considered.研究背景：柏林以其夜生活享誉全球。在全国及全欧范围内的横向对比中，柏林合法与非法精神活性物质的使用比例均高于其他同类城市。然而，针对派对场景中的药物使用情况，现有数据仍较为匮乏。 研究目的：本研究旨在评估柏林派对场景人群的社会人口学特征、精神活性物质使用模式，以及对预防干预的预期需求，以此制定针对性的预防措施。 研究方法：本研究采用线上（n = 674）与线下（n = 203）问卷调研的方式，共访谈877名柏林派对场景参与者。问卷内容涵盖参与者的人口统计学信息、该场景下的精神活性物质使用模式，同时收集了参与者对咨询服务的需求，以及对现有与拟推出的预防项目及服务有效性的个人评估。 研究结果：本研究参与者的平均年龄为29岁（标准差SD = 7.5），其中43%为女性。酒精是该派对场景中最常见的精神活性物质，其次依次为大麻、MDMA/摇头丸（MDMA/Ecstasy）、苯丙胺、可卡因与氯胺酮。在本研究队列中，甲基苯丙胺与“合法精神活性物质（legal highs）”并未占据主要地位。参与者需求最高的预防措施为加强药物相关教育，以及药物检测（drug-checking）服务。 研究结论：该领域的预防干预既存在现实需求，也得到了目标人群的广泛支持，因此应考虑扩大现有预防项目的覆盖范围——例如目前尚存政治争议的药物检测（drug-checking）服务。
