Identifying patterns and mechanistic pathways from violence exposure trajectories to aggressive behavior and psychological disorders

项目摘要 儿童和青少年的暴力暴露是一个主要的公共卫生问题， 短期和长期的影响，在所有领域的功能，包括学术，社会，身体， 心理上的虽然研究人员经常提到那些复杂和异质的经验， 大多数研究侧重于单一时间点和狭义背景下的接触情况。 因此，我们对（1）暴力暴露的性质、时间和共同发生的信息很少 （2）发展过渡和不同的环境如何影响暴露模式或概况，以及 (3)不同的暴露模式和暴露时间是否可以不同地预测 心理健康和随后的暴力行为等后果。拟定的研究将 系统地研究儿童和青少年遭受暴力的时间和模式， 不同类型的暴力可能影响心理健康发展轨迹的机制， 物质使用和暴力犯罪。我们建议分析来自纵向研究的数据， 儿童虐待和虐待（LONGSCAN; N=1354），以描述受害和暴露经历 （统称为暴力暴露）从出生到18岁以及短期和长期后果。 该项目的具体目标是：（1）描述暴力暴露的发展模式， 对从出生到18岁的高危儿童进行抽样调查，（2）查明暴力的短期和长期影响 暴露于心理健康问题，和青年犯下的暴力和（3）检查中介影响 关于暴力暴露轨迹和结果。该提案利用了现有的大规模， 纵向数据集，对感兴趣的领域提供前所未有的详细信息，包括重复的，多信息提供者 受害和暴力暴露经历评估，心理健康多点评估， 参与实施暴力。我们预计，这项研究将推动优先事项， NICHD，以更好地了解暴力暴露在整个发展过程中的演变和影响，并帮助 为将研究转化为有效的预防和干预工作提供信息。

Project Summary Violence exposure among children and adolescents is a major public health concern associated with significant short and long-term consequences in all domains of functioning including academic, social, physical, and psychological. Although researchers often refer to the complex and heterogeneous experiences of those exposed to violence, most studies focus on exposure at a single-time points and in narrowly defined contexts. As a result, we have scant information about (1) the nature, timing, and co-occurrence of violence exposure types, (2) how developmental transitions and different contexts influence patterns or profiles of exposure, and (3) whether different patterns of exposure and the timing of exposure differentially predict trajectories of outcomes such as mental health and subsequent perpetration of violence. The proposed study will systematically examine the timing and patterning of violence exposure in childhood and adolescence and the mechanisms by which different types of violence may influence developmental trajectories of mental health, substance use, and the perpetration of violence. We propose to analyze data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN; N=1354) to characterize victimization and exposure experiences (collectively referred to as violence exposure) from birth to age 18 and the short and long-term consequences. The specific aims of the project are to (1) describe the developmental patterns of violence exposure in a sample of high-risk children from birth to age 18, (2) identify the short and long-term effects of violence exposure on mental health problems, and youth perpetration of violence and (3) examine mediating influences on violence exposure trajectories and outcomes. This proposal capitalizes on an existing, large-scale, longitudinal dataset with unprecedented detail on the areas of interest including repeated, multi-informant assessments of victimization and violence exposure experiences, multi-point assessment of mental health and engagement in the perpetration of violence. We anticipate that this research will advance the priorities of NICHD to better understand the evolution and impact of violence exposure across development, and help to inform the translation of research into effective prevention and intervention efforts.
