Exposure to a traumatic event is concurrently and prospectively associated with disordered-eating behaviors such as binge eating, restricting, and purging. Specifically, purging has been found to be elevated in individuals with trauma histories, suggesting that purging may be a method for coping with trauma-related distress. However, there has been limited research investigating whether the time at which trauma occurs during development is differentially associated with disordered-eating behaviors and internalizing psychopathology. The purpose of this study was to examine the effect of trauma that occurred in childhood, adulthood, or childhood and adulthood on eating disorder (ED) and internalizing psychopathology. Participants were community-recruited adults with a current DSM-5 ED (N = 225) and were subsequently grouped into categories based on the time at which trauma occurred. Groups included: no trauma exposure ED controls (n = 54), child trauma group (n = 53), adult trauma group (n = 53), and child+adult trauma group (n = 65). We compared groups on their level of disordered-eating symptoms. Participants were administered the Structured Clinical Interview for DSM-IV, the Eating Pathology Symptoms Inventory (EPSI), and the Inventory of Depression and Anxiety Symptoms-II (IDAS-II). Univariate analyses revealed significantly higher levels of purging symptomatology in the child+adult trauma group compared to the no trauma, child trauma, and adult trauma groups. The current study highlights the importance of assessing the timing of trauma among individuals with EDs. In particular, our study indicates a need for further investigation to explain why individuals with ED and trauma histories engage in greater purging.

暴露于创伤事件与饮食失调行为（例如暴饮暴食，节食和排泄）同时并潜在地相关。具体而言，发现具有创伤史的人的清除率升高，这表明清除可能是应对创伤相关困扰的方法。但是，研究发育期间创伤发生的时间是否与饮食失调行为和内在的心理病理学差异相关的研究有限。这项研究的目的是检查在童年，成年或童年和成年时期发生的创伤对进食障碍（ED）和内在心理病理学的影响。参加者为社区招募的成年人，他们目前的DSM-5 ED（N = 225），然后根据发生创伤的时间分为几类。组包括：无创伤曝光ED对照（Ñ  = 54），儿童创伤组（Ñ  = 53），成人创伤组（N =  53） ，和子+成人创伤组（N =  65） 。我们比较了各组饮食失调症状的水平。参加者接受了DSM的结构化临床访谈-IV，饮食病理症状量表（EPSI）和抑郁与焦虑症状量表II（IDAS-II）。单因素分析显示，与无外伤，儿童外伤和成人外伤组相比，儿童+成人外伤组的清除症状水平明显更高。当前的研究强调了评估ED患者中创伤时机的重要性。特别是，我们的研究表明需要进一步调查，以解释为什么具有ED和创伤史的人进行更大的清除。
