精神病与严重和频繁的暴力和反社会行为有关，但很少有 了解它的结构和有效性在青年。更少的是知道女性的精神病，一组在 侵略和暴力的巨大风险。目的：这项研究将探讨精神病在一个 多种族样本的虐待和比较青少年在洛杉矶（洛杉矶），并增加 对这一重要的暴力风险因素的基本认识，特别是在年轻女性中。 具体目标：a）描绘精神病的因素结构[通过反社会过程测量 ScreeningDevice（APSD;弗里克& Hare，2001）]; Ib）检验结果的不变性 跨性别、种族和虐待组的因素模型2）为了检验 APSD的多特征、多方法研究; 3）探讨APSD与 心理变态和攻击性行为问题和犯罪主要假设：1）三因素结构： 将最好地表征APSD; 2）APSD将显示出跨性别的不变性; 3）当检查时 分别在男性和女性中，APSD将显示交叉被调查者的有效性; 4）广泛地说，精神病将 与攻击性、行为问题和犯罪行为显著正相关。研究设计：The 拟议的研究利用了南加州大学青少年项目第3个时间点收集的数据，该项目正在进行中。 关于忽视对发展影响的纵向研究（佩内洛普·特里克特博士，PI）。参与者：研究 组（N=303）是从洛杉矶儿童部证实的虐待报告中招募的， 洛杉矶市区10个邮政编码内的家庭服务。 对照组（N=151）是从1999年的学校招募的。 同样的10个邮政编码研究入组时的平均年龄为10.9岁（SD=1.15），包括53%的男性，39%的男性，10%的女性，10%的男性。 拉丁裔、37%非裔美国人、12%白色人和12%混合/混血参与者。数据还收集自 看护人和老师测量：APSD评分将与 父母和自我报告儿童行为的攻击性/欺凌和犯罪行为不良分量表 检查表（Achenbach，1991;参见Nollet等人，Reactive-Proactive Questionnaire（Raine et 例如，出版中）和自我报告的青少年犯罪问卷（见Huizinga &莫尔斯，1986）。

Psychopathy is associated with severe and frequent violence and antisocial behavior, but little is known about its structure and validity in youth. Even less is known about psychopathy in females, a group at substantial risk for aggression and violence. Objectives:The proposed study will examine psychopathy in a multiethnic sample of maltreated and comparison adolescents in Los Angeles (LA),and increase fundamental knowledge about this important risk factor for violence, particularly among young females. Specific Aims: la) To delineate the factor structureof psychopathy [as measured bythe AntisocialProcess ScreeningDevice (APSD; Frick& Hare, 2001 )] in this sample; Ib) To test the invariance of the resultant factor model across gender, ethnic and maltreatment group 2) To examine the cross-informant validity of the APSD via multitrait, multimethod approaches; and 3) To investigatethe relationship between APSD psychopathy and aggression, conduct problems, and delinquency. Major Hypotheses: 1) a 3-factor structure: will best characterize the APSD; 2) the APSD will show noninvariance across gender; 3) when examined separately in males and females, the APSD will show cross-informant validity; 4) broadly, psychopathy will be significantly positively related to aggression, conduct problems and delinquency. Study Design: The proposed study utilizes data collected at the 3rd timepoint of the USC Young Adolescent Project, an ongoing longitudinal study of the impact of neglect on development (Dr. Penelope Trickett, PI). Participants: A study group(N=303) was recruited from substantiated maltreatment reports to the LA Department of Child and Family Services within 10 zipcodes in urban LA. A comparison group (N=151)was recruited from schools in the same 10 zipcodes. Mean age at study entry was 10.9 years (SD=1.15), and comprised 53% male, 39% Latino,37% AfricanAmerican, 12% White and 12% mixed/biracial participants. Data is also collected from caretakers and teachers. Measures: APSD scores will be correlated with scores on the Aggressiveness/Bullyingand Delinquent Misbehavior subscales of the parent and self-report Child Behavior Checklist (Achenbach, 1991; see Nollet al., in preparation), the Reactive-Proactive Questionnaire (Raine et al., in press), and the self-report Adolescent Delinquency Questionnaire (see Huizinga & Morse, 1986).
