Neighborhood Context and Adolescent Psychological and Behavioral Health

描述（申请人提供）：本研究有四个目的：（1）加深对邻里结构特征与心理和行为健康关系的理解（内化和外化问题）在城市青少年中，并严格调查可能影响青少年幸福感的关键邻里水平的社会过程指标;（2）通过近缘发展情境（即，父母和同伴关系）和创伤经历（即，暴露于社区暴力）;（3）确定邻里过程是否制约了近缘发展背景和经历对青少年心理和行为健康的影响;（4）检查邻里背景和关键人口特征（性别和种族/民族）对青少年健康的相互依赖的贡献。该项目将主要集中在邻里水平过程的四个具体指标的影响：（1）集体效能，指的是居民之间的依恋和相互信任（即，社会凝聚力）以及由此产生的保护居民集体福祉免受威胁的意愿（即，非正式社会控制Sampson，2003; Sampson，Raudenbush，& Earls，1997; Sampson & Wilson，1995）;（2）无序，指的是公开的越轨行为（例如，常见的街头犯罪，如毒品交易和卖淫，公共争论，公共醉酒）和越轨和腐烂的物证（例如，街头的针头/注射器，街头的垃圾; Skogan，1990年; Sampson & Raudenbush，1999年）;（3）社会生态学，其特征是传统的户外步行交通的普遍存在以及由此产生的对公共空间的社会控制（Duany，Plater-Zyberk，& Speck 2000）;（4）机构资源，指的是社区组织和卫生保健设施等资源（Leventhal &布鲁克斯-古恩，2000）。为了解决研究的目的，我们将使用从项目人类发展在芝加哥社区（PHDCN）的数据-一个创新的多研究项目，专门设计，以促进对青年发展的背景影响的理解。分析将涉及三个PHDCN数据源：（1）来自四个年龄组的青年的纵向队列研究数据（1995年9岁、12岁、15岁和18奥尔兹），从80个芝加哥社区中选出（N = 2，978）;（2）对芝加哥居民进行的独立社区调查（N=8782; 1995）;（3）系统的社会观察研究超过15,000块内的80个街区的抽样脸。我们的分析方法将结合联合收割机多层次和空间统计模型来探索关键假设。研究结果有可能阐明邻里水平的不利影响青少年心理和行为健康的关键途径。公共卫生相关性：这项研究将有助于更好地了解邻里因素如何影响青少年的心理和行为健康。研究结果可能有助于指导旨在解决城市青少年健康问题的干预措施，无论是针对干预的社区类型，还是最有可能影响青少年结果的社区结构和社会过程特征。

DESCRIPTION (provided by applicant): The proposed study has four aims: (1) to advance understanding of the relationship between neighborhood structural characteristics and psychological and behavioral health (internalizing and externalizing problems) among urban adolescents and, critically, to investigate key neighborhood-level social process indicators that may influence adolescent well-being; (2) to investigate potential indirect pathways between neighborhood social processes and adolescents' psychological and behavioral health via proximate developmental contexts (i.e., parent and peer relationships) and traumatic experiences (i.e., exposure to community violence); (3) to determine whether neighborhood processes condition the influence of proximate developmental contexts and experiences on adolescents' psychological and behavioral health; and (4) to examine the interdependent contributions of neighborhood context and key demographic characteristics (gender and race/ethnicity) to adolescent health. The project will focus largely on the influence of four specific indicators of neighborhood level processes: (1) collective efficacy, which refers to attachment and mutual trust among residents (i.e., social cohesion) and to the resultant willingness to protect against threats to residents' collective well-being (i.e., informal social controls Sampson, 2003; Sampson, Raudenbush, & Earls, 1997; Sampson & Wilson, 1995); (2) disorder, which refers both to public acts of deviance (e.g., common street crimes such as drug dealing and prostitution, public arguments, public intoxication) and to physical evidence of deviance and decay (e.g., needles/syringes on the streets, garbage on the streets; Skogan, 1990; Sampson & Raudenbush, 1999); (3) social ecologies, which are characterized by the prevalence of conventional outdoor foot traffic and the resulting social control of public spaces (Duany, Plater-Zyberk, & Speck 2000); and (4) institutional resources, which refer to resources such as neighborhood organizations and health care facilities (Leventhal & Brooks- Gunn, 2000). To address study aims, we will use data from the Project on Human Development in Chicago Neighborhoods (PHDCN) - an innovative multi-study project specifically designed to promote understanding of contextual influences on youth development. Analyses will involve three PHDCN data sources: (1) the Longitudinal Cohort Study data from youth in four age cohorts (9, 12, 15, and 18 year olds in 1995) selected from 80 Chicago neighborhoods (N = 2,978); (2) an independent Community Survey of Chicago residents (N=8782; 1995); and (3) a Systematic Social Observation study of over 15,000 block faces within the sampled 80 neighborhoods. Our analytic approach will combine multilevel and spatial statistical models to explore key hypotheses. Findings from the study have the potential to illuminate critical pathways through which neighborhood level disadvantage influences adolescent psychological and behavioral health. PUBLIC HEALTH RELEVANCE: The proposed research will contribute to a better understanding of how neighborhood factors affect adolescent psychological and behavioral health. Findings from the research may help guide interventions that aim to address urban adolescent health, both with respect to the types of neighborhoods that should be targeted for intervention and the neighborhood level structural and social process characteristics that are most likely to influence adolescent outcomes.
