Abstract

The experience of traumatic events in childhood is an important risk factor for the initiation and continuation of polysubstance use. This study aimed to examine the mediating role of DSM-5 level of personality functioning and maladaptive personality traits in the relationship between traumatic life events and polysubstance use. We used a mixed sample (N = 290; M_age = 40; SD_age = 12.26; 75.2% males) of patients with substance use disorder (SUD; including 90 mono-drug users and 113 polysubstance users) and non-users (including 87 university students) recruited using convenience sampling method from harm reduction-oriented drug treatment centers and universities respectively in Tehran, Iran. Participants completed the Level of Personality Functioning Scale-Brief Form, the Personality Inventory for DSM 5-Brief Form, and the Life Events Checklist-Revised. The results of structural equation modeling showed that DSM-5 level of personality functioning and maladaptive personality traits partially mediated the relationship between traumatic life events and polysubstance use. Experiencing traumatic events may contribute to the risk of polysubstance use through the effect of global personality dysfunction and specific personality traits. This proposed mediational model must be replicated using a longitudinal design across different populations.

创伤性生活事件与多物质使用的关系:DSM-5人格功能水平和适应不良人格特征的中介作用

童年创伤性事件的经历是开始和继续使用多种物质的重要危险因素。本研究旨在探讨DSM-5人格功能水平和适应不良人格特征在创伤性生活事件与多物质使用关系中的中介作用。我们使用混合样本(N = 290;法师= 40;SDage = 12.26;75.2%男性)的物质使用障碍(SUD;采用便利抽样方法，分别从伊朗德黑兰以减少危害为重点的戒毒中心和大学招募了90名单一药物使用者和113名多种药物使用者和87名非使用者(包括87名大学生)。参与者完成了人格功能水平量表-简要表、DSM - 5-简要表人格清单和生活事件清单-修订。结构方程模型的结果表明，人格功能水平和适应不良人格特征在创伤性生活事件与多物质使用的关系中起部分中介作用。经历创伤性事件可能通过整体人格功能障碍和特定人格特征的影响而增加多物质使用的风险。这个提议的中介模型必须在不同人群中使用纵向设计进行复制。
