We sought to identify neighborhood-level resources associated with lower levels of aggression and delinquency among youths aged 9-15 years at baseline after accounting for risk factors and other types of resources.
Data were derived from the Project on Human Development in Chicago Neighborhoods, which focused on 2226 ethnically diverse, urban youths, their caregivers, and the 80 neighborhoods in which they resided at baseline.
Living in a neighborhood with a higher concentration of organizations or services serving young people and adults was associated with lower levels of aggression (odds ratio [OR]=0.9; 95% confidence interval [CI]=0.8, 1.0); living in such a neighborhood also moderated family, peer, and mentor resources. For example, the presence of well-behaved peers was associated with lower levels of aggression among youths living in neighborhoods where the concentration of organizations and services was at least 1 standard deviation above the mean; the association was less strong among youths living in neighborhoods with organizations and services 1 standard deviation below the mean or less.
Certain family, peer, and mentoring resources may confer benefits only in the presence of neighborhood resources. Increasing neighborhood resources should be considered in interventions designed to reduce urban youths' involvement in violence.
在考虑风险因素和其他类型资源的情况下,我们试图确定与9至15岁青少年在基线时较低攻击和犯罪水平相关的社区层面资源。
数据来自芝加哥社区人类发展项目,该项目聚焦于2226名种族多样的城市青少年、他们的照顾者以及他们在基线时居住的80个社区。
生活在为年轻人和成年人提供服务的组织或服务机构集中度较高的社区与较低的攻击水平相关(优势比[OR]=0.9;95%置信区间[CI]=0.8,1.0);生活在这样的社区也会调节家庭、同伴和导师资源。例如,在组织和服务集中度至少比平均水平高1个标准差的社区中,行为良好的同伴的存在与青少年较低的攻击水平相关;在组织和服务比平均水平低1个标准差或更低的社区中,这种关联则较弱。
某些家庭、同伴和指导资源可能仅在有社区资源的情况下才会带来益处。在旨在减少城市青少年暴力行为的干预措施中,应考虑增加社区资源。
