Young people experiencing houselessness are at high risk for revictimization. As has been identified in other populations, symptoms of psychological distress may be an indirect pathway by which initial victimization may increase risk for later revictimization among youth experiencing houselessness. The current study used cross-sectional mediation analyses to examine the hypothesis that there would be an indirect effect of interpersonal victimization that occurred before young people left home on subsequent victimization while experiencing houselessness, through posttraumatic stress disorder (PTSD) and depression symptoms. Youth (N = 245) residing in a shelter provided responses during an in-person interview screening prior to participating in a larger clinical study. Relevant to the current study, youth reported victimization experiences before and after leaving home (Childhood Trauma and Juvenile Victimization Questionnaires, respectively), and PTSD and depression symptoms on the Mini International Neuropsychiatric Interview. Results replicated and extended previous findings determining high rates of victimization among houseless young people both before (92%) and after (75%) leaving home. Further, exposure to more types of childhood victimization significantly predicted likelihood of experiencing more types of victimization after leaving home. Significant indirect effects of childhood victimization risk on revictimization after leaving home were found, occurring through both PTSD and depression symptoms. Results are discussed in terms of existing theories of revictimization, with particular emphasis on the state-dependence theory of victimization. These findings have implications for intervention with young people experiencing houselessness, particularly with regard to addressing the consequences of childhood victimization and trauma-informed support systems.

无家可归的年轻人再次受害的风险很高。正如在其他人群中发现的那样，心理困扰的症状可能是一种间接途径，最初的受害可能会增加无家可归的青年以后再次受害的风险。目前的研究使用横断面中介分析来检验这样一个假设，即年轻人离开家之前发生的人际受害对随后的受害会通过创伤后应激障碍 (PTSD) 和抑郁症状产生间接影响。青年（N= 245) 居住在庇护所中的人在参加更大规模的临床研究之前的面谈筛选期间提供了答复。与目前的研究相关，青少年报告了离家前后的受害经历（分别为童年创伤和青少年受害问卷），以及迷你国际神经精神病学访谈中的 PTSD 和抑郁症状。结果复制并扩展了先前的研究结果，确定了无家可归的年轻人在离家之前（92%）和之后（75%）的高受害率。此外，接触更多类型的童年受害显着预测离家后经历更多类型受害的可能性。发现童年受害风险对离家后再次受害的显着间接影响，通过创伤后应激障碍和抑郁症状发生。结果根据现有的再受害理论进行了讨论，特别强调了受害的国家依赖理论。这些发现对干预无家可归的年轻人具有重要意义，特别是在解决儿童受害和创伤知情支持系统的后果方面。
