目的基于扎根理论探讨影响成都市成华区新型毒品滥用的可能因素。方法采用非概率立意抽样对新型毒品滥用者及关键人物进行个人深入访谈,依据扎根理论三级编码流程实现转录资料的概念化、范畴化与理论化。结果经开放式编码,抽象出51个概念和16个范畴;经主轴编码范畴化出风险意识、行为意志、行为情境、行为驱动、社交网络、法制环境、禁毒戒毒环境和毒品环境八大因素;经核心编码构建理论框架。结论新型毒品滥用是内外因共同作用的结果,成华区今后的禁毒策略应基于八大影响因素做出合理调整,以实现新型毒品滥用的有效防控。 Objective To explore the possible factors influencing new drug abuse in Chenghua District of Chengdu based on grounded theory. Methods Non-probabilistic sampling was used to conduct in-depth interviews with new drug abusers and key individuals. According to the three-level coding process of grounded theory, conceptualization, categorization and theorization of transcriptional data were carried out. Results The 51 concepts and 16 categories were abstracted by open coding. Eight categories of risk consciousness, behavioral intention, behavioral situation, behavior-driven, social network, legal environment, anti-drug addiction drug treatment environment and drug environment were categorized through the main shaft code. Core coding to build a theoretical framework. Conclusions The new drug abuse is the result of both internal and external causes. In the future, the anti-drug strategy in Chenghua District should be adjusted reasonably based on the eight influential factors so as to effectively prevent and control new types of drug abuse.
