Among youth in foster care (N = 303, aged 11–17 years), we investigated prevalence of internalizing symptoms; associations between symptom level and maltreatment types and numbers; and the interaction between gender and maltreatment, on internalizing symptoms. Youth completed Spence Children Anxiety Scale, Short Mood Feelings Questionnaire, and Child and Adolescent Trauma Screen. Compared to community samples, symptom levels above clinical cut-off was more frequent, with social- and generalized anxiety (ES = 0.78–0.88) being most prevalent among youth in foster care. Girls reported more internalizing symptoms (ES = 0.59–0.93). Sexual abuse and neglect were associated with a broader range of internalizing symptoms (ES = 0.35–0.64). Increased incidence of maltreatment was associated with increased levels of symptoms (ES = 0.21–0.22). Associations between maltreatment and symptom level were stronger for girls. This study stresses the importance of broad screening of maltreatment and internalizing symptoms to meet the needs of youth in foster care.

在寄养青年中（N = 303，年龄 11-17 岁），我们调查了内化症状的患病率；症状水平与虐待类型和数量之间的关联；以及性别和虐待之间的相互作用，对内化症状。青少年完成了 Spence 儿童焦虑量表、短情绪感觉问卷以及儿童和青少年创伤筛查。与社区样本相比，高于临床临界值的症状水平更为常见，社交和广泛性焦虑（ES = 0.78-0.88）在寄养青少年中最为普遍。女孩报告了更多的内化症状（ES = 0.59-0.93）。性虐待和忽视与更广泛的内化症状相关（ES = 0.35-0.64）。虐待发生率的增加与症状水平的增加有关（ES = 0.21-0.22）。女孩的虐待与症状水平之间的关联更强。这项研究强调了广泛筛查虐待和内化症状以满足青少年寄养需求的重要性。
