项目摘要

DESCRIPTION (provided by applicant): A randomized trial of abandoned housing remediation, substance abuse and violence Housing abandonment poses a major health burden that has grown significantly over the past several decades in the US. As a typical US city, Philadelphia has some 40,000 vacant properties, a significant number with abandoned residential buildings or structures. Research, including our own, has shown that vacant and abandoned properties are associated with drug- dependence, firearm violence, stress, sexually transmitted diseases, and premature mortality. Our prior research also shows that urban residents see abandoned buildings every day on their way to work or school and describe these undesirable structures as foremost, hypervisible detractors to community health, reducing community cohesion and creating trash, rodents, crime, fear, stress, and havens for transients, drug use, and sex work. Multiple theories posit that visible, environmental disorders, such as abandoned buildings, lead to community decline by signaling that a community is uncared-for, incivilities are tolerated, and the ability of residents to engage in shared expectations of social control over neighborhood problems is eroded. As a result, residents are prevented from engaging in positive health behaviors while unhealthy behaviors, such as substance abuse and violence, become sheltered and more prevalent. Direct remediation of abandoned housing could thus be a potent intervention to interrupt longstanding substance abuse and violence. The proposed research team has produced several preliminary/pilot studies that demonstrate its capacity to complete the proposed study: (1) a published, citywide quasi-experimental study of the health and safety effects of a novel abandoned building remediation protocol stemming from the 2011 Philadelphia Doors and Windows Ordinance; (2) multiple published pilot randomized controlled trials (RCTs) of the effects of abandoned and vacant property remediation on health and safety; and (3) a large, citywide RCT of vacant lot greening involving over 600,000 ft2 of land and a 5-wave, random sample survey of over 600 Philadelphians. There have been no RCTs that test the health and safety effects of abandoned housing remediation. The broad objective of this proposal addressed this gap in knowledge by conducting a citywide RCT of the effects of abandoned housing remediation on substance abuse outcomes, both alcohol and drug related, and violence outcomes, particularly firearm violence. A total of 320 randomly selected abandoned houses, stratified into four geographic sections of Philadelphia, will be randomly assigned to four trial arms: full abandoned housing remediation (n=80, full treatment), graffiti and trash clean-up only (n=80, graffiti treatment), trash clean-up only (n=80, contact control), and no housing remediation or clean-up (n=80, no treatment). Longitudinal outcomes on and near the abandoned houses will be measured in the 18 months before and after treatment. Mixed, quantitative and qualitative methods, will be used to achieve the proposed specific aims in determining if abandoned housing remediation is a cost-effective approach to substance abuse and firearm violence.

描述（由适用提供）：一项关于废弃住房修复，滥用毒品和暴力住房的随机试验，废弃的财产是在过去几十年中大幅增长的重大健康烧伤。作为典型的美国城市，费城拥有约40,000个空置物业，这是一大批废弃的居民建筑物或建筑物。包括我们本人在内的研究表明，我们与毒品依赖，枪支暴力，压力，性传播疾病和过早死亡相关的空置和废弃特性。我们先前的研究还表明，城市居民在上班或上学的途中每天都看到废弃的建筑物，并将这些不可避免的结构描述为最重要的，令人难以置信的对社区健康的批评者，减少社区凝聚力并造成垃圾，啮齿动物，犯罪，犯罪，恐惧，恐惧，并具有瞬态，毒品，药物使用和性别工作。多种理论认为，可见的环境障碍，例如废弃的建筑物，通过信号表明社区是无非是，偶然的，居民参与社会共同期望的能力，从而导致社区下降控制邻里问题。结果，阻止居民从事积极的健康行为，而不健康的行为（例如滥用毒品和暴力）变得越来越普遍。因此，直接修复废弃的住房可能是中断长期滥用药物和暴力的潜在干预措施。拟议的研究团队已经进行了几项初步/试点研究，证明了其完成拟议的研究的能力：（1）一项针对2011年费城门和Windows法令的新型废弃建筑补救方案的健康和安全效应的出版，全市范围的实验性研究；（2）多个已发表的飞行员随机对照试验（RCT），这些试验（RCT）是废弃和空置财产修复对健康和安全的影响；（3）全市范围内的大型RCT涉及600,000英尺的土地和5波超过600多名费城人的5波随机调查。没有RCT测试废弃住房修复的健康和安全影响。该提案的广泛目标通过对废弃住房修复对滥用药物滥用结果的影响（与酒精和毒品相关的毒品滥用结果以及暴力结果，尤其是枪支暴力行为）进行了全市范围。总共有320个随机选择的废弃房屋分为费城的四个地理区域，将随机分配到四个试验臂：完全废弃的住房修复（n = 80，全面处理），仅涂鸦和垃圾清理（n = 80，接触控制，接触对照），没有住房修复或清理（n = 80，无需处理）。在治疗前后的18个月内，将在废弃房屋上和附近的纵向结局进行测量。混合，定量和定性方法将用于实现拟议的特定目的，以确定废弃的住房修复是否是滥用药物和枪支暴力的经济有效的方法。
