This study examines how neighborhood characteristics affect program efficacy. Data come from a randomized trial of a substance use prevention program called keepin' it REAL, which was administered to a predominantly Mexican American sample of 4,622 middle school students in Phoenix, Arizona, beginning in 1998. Multilevel models and multiple imputation techniques address clustered data and attrition. Among less linguistically acculturated Latinos, living in poorer neighborhoods and those with many single-mother families decreased program effectiveness in combating alcohol use. High neighborhood immigrant composition increased program effectiveness. Unexpectedly, the program was also more effective in neighborhoods with higher rates of crime. There were no significant effects on program efficacy for the more linguistically acculturated Latinos and non-Hispanic White students. Findings are discussed in light of theories of neighborhood social disorganization, immigrant adaptation, and social isolation.
本研究探讨邻里特征如何影响项目效果。数据来自一项名为“保持真实”的预防药物使用项目的随机试验，该项目从1998年开始在亚利桑那州凤凰城的4622名以墨西哥裔美国人为主的中学生样本中实施。多层模型和多重插补技术处理聚类数据和损耗问题。在语言文化适应程度较低的拉丁裔中，生活在较贫困社区以及单亲家庭较多的社区会降低项目在打击饮酒方面的效果。社区中较高的移民构成比例提高了项目效果。出乎意料的是，该项目在犯罪率较高的社区也更有效。对于语言文化适应程度较高的拉丁裔和非西班牙裔白人学生，项目效果没有显著影响。我们根据邻里社会失序、移民适应和社会隔离理论对研究结果进行了讨论。
