The aim of this study is to analyse the factors related to the use of addictive substances in adolescence using association rules, descriptive tools included in Data Mining. Thus, we have a database referring to the consumption of addictive substances in adolescence, and use the free distribution program in the R arules package (version 2.10.0). The sample was made up of 9,300 students between the ages of 14 and 18 (47.1% boys and 52.9% girls) with an average age of 15.6 (SE=1.2). The adolescents answered an anonymous questionnaire on personal, family and environmental risk factors related to substance use. The best rules obtained with regard to substance use relate the consumption of alcohol to perceived parenting style and peer consumption (confidence = 0.8528), the use of tobacco (smoking), cannabis and cocaine to perceived parental action and illegal behaviour (confidence = 0.8032, 0.8718 and 1.0000, respectively), and the use of ecstasy to peer consumption (confidence = 1.0000). In general, the association rules show in a simple manner the relationship between certain patterns of perceived parental action, behaviours that deviate from social behavioural norms, peer consumption and the use of different legal and illegal drugs of abuse in adolescence. The implications of the results obtained are described, together with the usefulness of this new methodology of analysis.
本研究旨在利用关联规则（数据挖掘中包含的描述性工具）分析青少年使用成瘾物质的相关因素。为此，我们构建了一个包含青少年成瘾物质使用情况的数据库，并使用 R 语言中的免费 distribution 程序包（版本 2.10.0）中的 arules 包。样本由 9300 名年龄在 14 至 18 岁之间（47.1%为男生，52.9%为女生）的青少年组成，平均年龄为 15.6（SE=1.2）。青少年们回答了一份关于与物质使用相关的个人、家庭和环境风险因素的匿名问卷。关于物质使用，我们获得了最佳的规则，涉及到酒精的消费与感知到的父母教养方式和同伴消费（置信度=0.8528）、烟草（吸烟）、大麻和可卡因的使用与感知到的父母行为和非法行为（置信度=0.8032、0.8718 和 1.0000）以及摇头丸的使用与同伴消费（置信度=1.0000）。总的来说，关联规则以简单的方式展示了某些感知到的父母行为模式、偏离社会行为规范的行为、同伴消费以及青少年时期使用不同合法和非法滥用药物之间的关系。描述了获得的结果的含义，以及这种新的分析方法的有用性。
