This longitudinal study identifies espoused change orientations and actual youth violence prevention (YVP) practices over five years by 99 public and nonprofit organizations in one city. Annual key informant interviews provided both qualitative and quantitative data, including organizational collaborative network data. Data were also obtained on participation in a citywide YVP coalition, juvenile arrests and court referrals. On average, organizations both in and outside the coalition adopted a problem-focused as often as a strengths-based change orientation, and were only marginally more oriented toward empowering community members than professionals and changing communities than individual youth. Most surprisingly, YVP coalition members adopted more of a tertiary (reactive/rehabilitative) than primary prevention orientation compared to nonmembers. The number of different YVP strategies implemented increased over five years from mainly positive youth development and education interventions to those strategies plus mentoring, youth activities, events and programs, and counseling youth. Network analysis reveals dense initial collaboration with no critical gatekeepers and coalition participants more central to the city-wide organizational network. Coalition participation and total network collaboration declined in Years 3–5. Youth violence arrests and court referrals also declined. The coalition was marginally involved in successful community-collaborative, school-based interventions and other strategies adopted, and it disbanded a year after federal funding ended. Despite, or possibly due to, both national and local government participation, the coalition missed opportunities to engage in collective advocacy for local YVP policy changes. Coalitions should help nonprofit and public organizations develop more effective change orientations and implement commensurate strategies at the community level.

这项纵向研究确定了一个城市 99 个公共和非营利组织五年来所拥护的变革方向和实际的青少年暴力预防 (YVP) 实践。年度关键知情人访谈提供了定性和定量数据，包括组织协作网络数据。还获得了有关参与全市 YVP 联盟、青少年逮捕和法庭转介的数据。平均而言，联盟内外的组织都采取了以问题为中心和基于优势的变革方向，并且比专业人士更倾向于为社区成员赋权，比个体青年更倾向于改变社区。最令人惊讶的是，与非成员相比，YVP 联盟成员更多地采用了三级（反应性/康复性）预防方向，而不是一级预防方向。五年来，实施的不同 YVP 战略的数量有所增加，从主要是积极的青年发展和教育干预措施，到这些战略加上指导、青年活动、活动和计划以及青年咨询。网络分析揭示了密集的初始协作，没有关键的看门人和联盟参与者对全市组织网络更重要。联盟参与度和总体网络协作在第 3-5 年有所下降。青少年暴力逮捕和法庭转介也有所下降。该联盟略微参与了成功的社区合作、基于学校​​的干预措施和采取的其他战略，并在联邦资助结束一年后解散。尽管或可能由于国家和地方政府的参与，该联盟错过了集体倡导地方 YVP 政策变化的机会。联盟应帮助非营利组织和公共组织制定更有效的变革方向，并在社区层面实施相应的战略。
