CDC Youth Violence Prevention Center- Kansas City (YVPC- KC): Evaluation of a Comprehensive Approach to Address Youth Violence

项目摘要 青年暴力是一个重大的公共卫生问题。2019年，每10万人中有46.9起凶杀案， 在堪萨斯城（KC）大都会地区，10至24岁的年轻人中有7.82人。青少年杀人 是全国15至24岁人群的第三大死因（国家伤害中心 预防，2021年），以及KC都会区这一年龄组青年死亡的主要原因。青年 暴力对种族和族裔青年的影响尤为严重。黑人和西班牙裔/拉丁裔青年的经验更大 全国和堪萨斯城（KC）都会区的青年暴力差异。2019年，57名青年中有71% KC都会区的凶杀案涉及10至24岁的黑人或西班牙裔/拉丁裔青年。 拟议中的KC青年暴力预防中心的目标是审查 ThrYve（共同帮助减少青年暴力）作为预防青年暴力的多方面方法 (i.e.,青少年凶杀案）并减少相关风险（例如，故意伤害住院），特别是 在黑人和拉丁裔青年中。地理重点是KC都会区，包括KC，KS和KC，MO 青少年暴力高发的社区ThrYve模型检查了两个 预防战略包括：（a）ThrYve 4Change，一项青年动员战略;（B）REVIVE，一项规模较大的 多地点医院暴力预防方案。基本原理是，使用更多的 跨越多个邻域的严格方法（即，学校集水区）， 暴力和高住院率将扩大有效性和普遍性的证据基础 预防和减少青年暴力的参与性战略。该研究将使用中断的时间序列， 跨越三个邻域的多个基线设计（即，在KC地铁区的学校集水区。 此外，将在四个当地医院地点评估一个多地点医院暴力预防方案。 本研究将探讨以下目标，以了解全面 社区结果和相关因素的预防战略：具体目标1：评估有效性 多组成部分ThrYve模式，包括ThrYve 4Change（青年动员战略）和REVIVE （通过干预和增强受害者能力减少暴力的影响） 预防方案）对社区条件变化的影响（即，预防措施、方案和 青少年犯罪率。具体目标2：审查ThrYve 4Change青年的影响 关于相关风险和保护因素的动员战略（例如，学业成绩）， 邻域（即，学校校区）。具体目标3：评估实施一项 针对与枪支有关的住院和青年再入院的大规模医院暴力预防方案 参与者

Project Abstract Summary Youth violence is a critical public health concern. In 2019, there were 46.9 homicides per 100,000 for youth ages 10 to 24 in the Kansas City (KC) metro area compared to 7.82 in the U.S. overall. Youth homicide is the third leading cause of death for individuals 15 to 24 years nationally (National Center for Injury Prevention, 2021), and the leading cause of death for youth in this age group in the KC metro area. Youth violence disproportionately affects racial and ethnic youth. Black and Hispanic/Latinx youth experience greater disparities in youth violence nationally and in the Kansas City (KC) metro area. In 2019, 71% of the 57 youth homicides in the KC metro area involved Black or Hispanic/Latinx youth ages 10 to 24. The goal of the proposed KC Youth Violence Prevention Center is to examine implementation of ThrYve (Together Helping Reduce Youth Violence) as a multicomponent approach to prevent youth violence (i.e., youth homicides) and reduce associated risks (e.g., intentional injury hospital admission), particularly among Black and Latinx youth. The geographic focus is the KC metro area, including both KC, KS & KC, MO neighborhoods with high rates of youth violence. The ThrYve model examines the implementation of two prevention strategies including: (a) ThrYve4Change, a youth mobilization strategy and (b) REVIVE, a scaled multisite hospital violence prevention program. The rationale is that testing the ThrYve model using a more rigorous approach across multiple neighborhoods (i.e., school catchment areas) with elevated rates of youth violence and high hospitalization rates will expand the evidence base for the effectiveness and generalizability of participatory strategies to prevent and reduce youth violence. The study will use interrupted time series and multiple baseline designs across three neighborhoods (i.e., school catchment areas) in the KC metro area. Additionally, a multisite hospital violence prevention program will be evaluated across four local hospital sites. The following aims will be examined in the study to understand the impact of the comprehensive prevention strategies on community outcomes and related factors: Specific Aim 1: Evaluate the effectiveness of the multi-component ThrYve Model, including ThrYve4Change (youth mobilization strategy) & REVIVE (Reducing the Effects of Violence through Intervention and Victim Empowerment) (multisite hospital violence prevention program) on changes in community conditions (i.e., prevention practices, programs, & policies) and youth homicide rates. Specific Aim 2: Examine the impact of the ThrYve4Change youth mobilization strategy on associated risks & protective factors (e.g., academic performance) for youth in three neighborhoods (i.e., school catchment areas). Specific Aim 3: Evaluate the effectiveness of implementing a scaled hospital violence prevention program on firearm-related hospital admissions and readmissions of youth participants.
