Polyvictimization is a robust predictor of emotional and behavioral problems and is linked to involvement in juvenile justice and other public sector systems. This study extends prior research by employing person-centered methods for identifying polyvictimization patterns among trauma-exposed, clinic-referred, justice-involved youth (n = 689; ages 12–18 years) and how identified classes differ on psychosocial outcomes and demographic characteristics. Most participants had experienced multiple traumatic event (TE) types. Latent class analyses identified three classes: mixed trauma/bereavement exposure group (55.1%; Mean = 3.0 TE types); maltreatment polyvictimized group (29.3%; Mean = 5.7 TE types); and maltreatment plus extreme violence polyvictimized group (15.7%; Mean = 9.3 TE types). Polyvictimized youth were more likely to be female, in out-of-home placements, and experiencing negative psychosocial outcomes (e.g., Posttraumatic Stress Disorder). Hispanic/Latino youth were overrepresented in the extreme polyvictimized subgroup. Results underscore the need for cross-system coordination of trauma-informed, comprehensive services for clinic-referred, justice-involved youth.

多重受害是情绪和行为问题的有力预测因素，并与参与少年司法和其他公共部门系统有关。本研究扩展了先前的研究，采用以人为中心的方法来识别遭受创伤、诊所转诊、参与司法的青年（n= 689; 年龄 12-18 岁）以及所确定的类别在社会心理结果和人口特征方面有何不同。大多数参与者都经历过多种创伤事件（TE）类型。潜在类别分析确定了三个类别：混合创伤/丧亲暴露组（55.1%；平均值 = 3.0 TE 类型）；虐待多受害者组（29.3%；平均值 = 5.7 TE 类型）；和虐待加极端暴力受害组（15.7%；平均值 = 9.3 TE 类型）。受多重伤害的青年更有可能是女性，在户外安置，并经历负面的心理社会结果（例如，创伤后应激障碍）。西班牙裔/拉丁裔青年在极端多受害者亚组中的比例过高。结果强调了为临床转介、参与司法的青年提供创伤知情、综合服务的跨系统协调的必要性。
