项目摘要

Ecological theory suggests that early adolescent peer groups regularly form which encourage problem behavior, leading to even closer, deviance-prone peer groups, and so on in a self-reinforcing cycle. We call this process ¿toxic peer contagion.¿ It is best conceptualized as a Nonlinear Dynamic System (NDS). We propose to develop NDS models that explain the onset to and growth of problem behaviors (antisocial behavior, aggression, substance use) in middle school peer social ecologies, and particularly to examine toxic peer contagion as an explanatory hypothesis. The study will be conducted in 21 sixth- to eighth-grade middle schools involved in an already underway, NIDA- funded group-randomized trial of the Positive Behavior Support (PBS) program. A major goal is to investigate variation in toxic peer contagion differences between schools, especially between PBS program and control schools. The project requires collecing social relationship (social network) and relevant behavioral data on multiple occasions, and observing the pattern of interdependence between them over time. Assessments will be conducted four times per school year, for two consecutive entering sixth-grade cohorts, through the end of their eighth-grade year in each of the 21 participating schools; thus, 12 observations per cohort. School-level models will be created using SIENA, a recently developed statistical methodology specifically designed to estimate models of evolving social networks and co-evolving behavior. Also, two-level models will be developed when effects vary significantly across schools. In order to accomplish these ambitious goals with this large, diverse sample of schools and students, it is necessary to perform several major upgrades to the SIENA computer software, improving its estimation performance by porting it to multiprocessor computing environments, and enhancing its ability to include interaction effects, full- information multilevel models, and cross-level interactions. For this purpose, we are partnering with the researchers who developed SIENA to make the upgrades necessary for project goals. The results of this project will include: (a) estimates of the prevalence of toxic peer contagion in a varigated sample of middle schools; (b) conditions under which it is most and least likely to occur; (c) the effectiveness of PBS as a way to discourage it; and (d) recommendations for peer-directed interventions for dealing with this problem. This project will examine the effect of a group-randomized trial of an already funded school-level positive behavior intervention on the over-time interdependence between early adolescent problem behavior and peer group dynamics. This process, developed from theories of social ecologies and development, is ¿toxic peer contagion.¿ Nonlinear dynamic models of affiliation-behavior interdependence will be statistically estimated from longitudinal (4x/yr, 6th to 8th grade) data using SIENA, a computer program specifically developed to model such processes. Results will explain the role of peer affiliations in development of problem behavior, the effect of positive behavior support on this linkage, and suggest new avenues for future interventions.
生态学理论表明,青春期早期的同龄人群体经常形成 鼓励问题行为,导致更紧密、更容易越轨的同龄人群体,以及 因此,在一个自我强化的循环中。我们称这一过程为“有毒的同伴传染”。 被概念化为一个非线性动力系统(NDS)。我们建议发展NDS 解释问题行为的产生和发展的模型(反社会行为, 攻击性、物质使用)在中学同龄人的社会生态中,尤其是 考察有毒同伴传染作为一种解释性假设。将进行这项研究 在已在进行的21所六至八年级中学中,NIDA- 资助小组-积极行为支持(PBS)计划的随机试验。一位少校 目标是调查学校之间有毒同伴传染差异的差异, 特别是在PBS项目和对照学校之间。 该项目需要收集社会关系(社交网络)和相关 在多个场合的行为数据,并观察相互依赖的模式 随着时间的推移他们之间的关系。每学年将进行四次评估, 连续两个进入六年级的队列,一直到八年级结束 在21所参与学校中的每一所学校;因此,每个队列有12个观察点。学校层面 将使用最近开发的统计方法锡耶纳创建模型 专为评估不断发展的社交网络和共同发展的模型而设计 行为。此外,当影响在以下方面差异很大时,将开发两级模型 学校。为了实现这些雄心勃勃的目标,我们需要大量、多样化的样本 学校和学生们,有必要对锡耶纳进行几次重大升级 计算机软件,通过将其移植到多处理器来提高其估计性能 计算环境,并增强其包括交互影响的能力,完全- 信息多层次模型和跨层次互动。为此,我们将 与开发锡耶纳的研究人员合作,进行必要的升级 对于项目目标。 该项目的成果将包括:(A)对有毒同龄人流行率的估计 在不同的中学样本中的传染性;(B)在什么情况下最容易感染 和最不可能发生;(C)公共广播服务作为阻止这种行为的一种方式的有效性;和(D) 对同行指导的干预措施的建议,以解决这个问题。该项目将检验已经资助的一项分组随机试验的效果。 学校层面积极行为干预对超时相互依赖关系的影响 青少年早期问题行为与同龄人群体动态。这一过程,发展了 从社会生态和发展的理论来看,是有毒的同伴传染。非线性 从属关系-行为相互依赖的动态模型将被统计地估计 使用计算机程序SIENA从纵向(4倍/年,6至8年级)数据 专门为模拟这类过程而开发。结果将解释同龄人的作用 问题行为发展中的从属关系、积极行为支持对 这种联系,并为今后的干预工作提出了新的途径。
