Self Enhancement, Inc., is a grassroots, community-service organization working in the most disadvantaged high-risk community in Portland, Oregon. Its violence-prevention program targets middle-school and high-school students by providing classroom and community activities to these young people. These activities are designed to enhance protective factors and build resilience in youths to enable them to attain healthy and productive lives and to resist the threats of gangs, violence, and drugs. RMC Research Corporation works in partnership with Self Enhancement, Inc., to conduct research and evaluation on the effectiveness of its programs. The Self Enhancement, Inc., program works primarily at the individual student and interpersonal relationship levels. Resilience Theory and its culturally specific Relationship Model drive the formulation of specific strategies and activities. Program staff mentor each student through his or her preadolescent and adolescent years, promoting positive, prosocial norms and expectations for behavior through their peer group activities. The Self Enhancement, Inc., program consists of three major components: classroom, exposure, and proactive education. Classroom education focuses on anger management, conflict resolution, and problem solving. Exposure education consists of quarterly field trips to agencies and organizations in the Portland area that deal with the causes and consequences of violence in the community. Proactive education includes newsletters, student-run assemblies and conferences, and radio/ television public service announcements that communicate antiviolence messages. The evaluation plan is a longitudinal matched comparison group designed to assess the outcomes of the violence-prevention program. Key outcomes are protective factors, health-risk behaviors, and academic measures. Standardized assessment instruments (the Individual Protective Factors Index and the Youth Risk Behavior Survey) were administered to all students during winter 1994. The instruments will be readministered during the same period in the following two years of the project. School records were extracted to assess students' attendance and progress through their academic programs. Of the 326 seventh-, eighth-, and ninth-grade students participating in this study, 95% are African Americans and 51% are boys. The prevalence of fighting (56%) during the past 12 months is higher than that among African-American high-school students nationally, but weapon carrying (27%), alcohol use (30%), and marijuana use (18%) are the same or lower than national averages for this group. All baseline indicators are equivalent between the program and comparison groups with the exception of weapon carrying. Program students report carrying weapons more than do their comparison group counterparts. Baseline indicators of violence-related behaviors clearly indicate the need for intervention in this highly disadvantaged, African-American community. Through its historical presence and recent program development efforts, Self Enhancement, Inc., is well positioned to make a difference in the lives of these young people. The equivalence of program and comparison group students on baseline indicators of violence bodes well for an unequivocal assessment of program effectiveness over time.
自我提升公司是一个基层社区服务组织,在俄勒冈州波特兰市最贫困的高风险社区开展工作。其预防暴力项目针对初中和高中学生,为这些年轻人提供课堂和社区活动。这些活动旨在增强保护因素,培养青少年的适应能力,使他们能够过上健康、有意义的生活,并抵御帮派、暴力和毒品的威胁。RMC研究公司与自我提升公司合作,对其项目的有效性进行研究和评估。自我提升公司的项目主要在个体学生和人际关系层面开展。适应能力理论及其特定文化背景下的关系模型推动了具体策略和活动的制定。项目工作人员在学生的青春期前和青春期对每个学生进行指导,通过同伴群体活动促进积极、亲社会的行为规范和行为期望。自我提升公司的项目包括三个主要部分:课堂教育、体验教育和主动教育。课堂教育侧重于愤怒管理、冲突解决和问题解决。体验教育包括每季度一次前往波特兰地区处理社区暴力原因和后果的机构和组织的实地考察。主动教育包括时事通讯、学生组织的集会和会议,以及传达反暴力信息的广播/电视公益广告。评估计划是一个纵向匹配比较组,旨在评估预防暴力项目的成果。关键成果包括保护因素、健康风险行为和学业指标。1994年冬季,对所有学生进行了标准化评估工具(个人保护因素指数和青少年风险行为调查)的测试。在项目的接下来两年的同一时期将再次进行这些工具的测试。提取学校记录以评估学生的出勤情况和学业进展。参与本研究的326名七年级、八年级和九年级学生中,95%是非洲裔美国人,51%是男生。在过去12个月中打架的发生率(56%)高于全国非洲裔美国高中生的发生率,但携带武器(27%)、饮酒(30%)和使用大麻(18%)与该群体的全国平均水平相同或更低。除了携带武器外,项目组和对照组的所有基线指标都相当。项目组学生报告携带武器的情况比对照组学生更多。与暴力相关行为的基线指标清楚地表明,在这个高度贫困的非洲裔美国社区需要进行干预。通过其长期的存在和最近的项目开发努力,自我提升公司有能力改变这些年轻人的生活。项目组和对照组学生在暴力基线指标上的相当情况,为随着时间推移明确评估项目有效性提供了良好的兆头。
