Exposure to trauma is considered a risk factor for the development of addictive disorders. Currently, there is a knowledge gap concerning specific links between types and levels of exposure to traumatic events and addiction. In this study we explored the associations between interpersonal trauma and risk of addictive behaviors, stratified by type of trauma (physical, weapon, sexual assault, and combat) and level of exposure (direct/indirect), focusing on a wide range of substances and behaviors. Data from an online representative sample of 4025 respondents were collected, including the Life Events Checklist (LEC-5), substance use disorders and behavioral addictions metrics, and sociodemographic data. Substantial differences were found between specific types of trauma and risk of addiction. Among those exposed to sexual assault, the risk of alcohol use disorder was found to 15.4%, 95%CI[14.4–16.4%], compared to 12.1%,95%CI[11.3–12.8] among those exposed to combat-related trauma. Both direct and indirect exposure to trauma were found to be significantly related with risk of addiction. While direct exposure was most highly associated with addictions across several types of trauma, in the case of combat-related trauma, indirect exposure was more highly associated with alcohol and pornography addiction (14.5%,95%CI[13.2–15.8%] and 10.0%, 95%CI[6.3–15.0%], respectively) compared to direct exposure (10.7%,95%CI[9.9–11.6%] and 7.4%, 95%CI[4.7–11.6%], respectively). Our findings emphasize the strong association between all types of trauma and the risk of several specific substance and behavioral addictions. Specifically, the role of indirect exposure to trauma is highlighted.

接触外伤被认为是导致成瘾性疾病的危险因素。当前，关于创伤事件和成瘾的暴露类型和水平之间的具体联系存在知识鸿沟。 在这项研究中，我们探讨了人际创伤与成瘾行为风险之间的关联，并按创伤类型（身体，武器，性攻击和战斗）和接触水平（直接/间接）进行了分层，重点研究了多种物质和行为。从4025名受访者的在线代表性样本中收集了数据，包括生活事件清单（LEC-5），物质使用障碍和行为成瘾指标以及社会人口统计学数据。发现特定类型的创伤和成瘾风险之间存在实质性差异。在遭受性侵犯的人中，发现饮酒障碍的风险为15.4％，95％CI [14.4–16.4％]，而在与战斗有关的创伤中，则为12.1％，95％CI [11.3-12.8] 。发现直接和间接暴露于创伤均与成瘾风险显着相关。虽然直接接触与多种类型的创伤成瘾相关性最高，但在与战斗有关的创伤中，间接接触与酒精和色情成瘾相关性更高（分别为14.5％，95％CI [13.2–15.8％]和10.0 ％，分别为95％CI [6.3-15.0％]和直接暴露（分别为10.7％，95％CI [9.9-11.6％]和7.4％，95％CI [4.7-11.6％]）。我们的研究结果强调了所有类型的创伤与几种特定物质和行为成瘾风险之间的密切联系。具体而言，强调了间接接触创伤的作用。与直接接触（10.7％，95％）相比，间接接触与酒精和色情成瘾的相关性更高（分别为14.5％，95％CI [13.2–15.8％]和10.0％，95％CI [6.3-15.0％]）。 CI [9.9-11.6％]和7.4％，95％CI [4.7-11.6％]）。我们的研究结果强调了所有类型的创伤与几种特定物质和行为成瘾风险之间的密切联系。具体而言，强调了间接接触创伤的作用。与直接接触（10.7％，95％）相比，间接接触与酒精和色情成瘾的相关性更高（分别为14.5％，95％CI [13.2–15.8％]和10.0％，95％CI [6.3-15.0％]）。 CI [9.9-11.6％]和7.4％，95％CI [4.7-11.6％]）。我们的研究结果强调了所有类型的创伤与几种特定物质和行为成瘾风险之间的密切联系。具体而言，强调了间接接触创伤的作用。
