Defining CVI: A Critical Review of Current Conceptualizations and Their Implications for Policy,Research and Practice

Abstract

Community Violence Intervention (CVI) operates at the critical intersection of public health and public safety, offering a community-driven approach to reducing violence while addressing its root causes. Grounded in principles of harm reduction, trauma-informed care, and social determinants of health, CVI reframes violence as a public health crisis rather than solely a criminal justice issue. Despite its promise and demonstrated impact, the field of CVI faces challenges that reflect broader gaps in public health policy. A lack of standardized definitions and measurement frameworks has led to fragmented policies, inconsistent funding, and difficulties in scaling evidence-informed approaches. These issues mirror struggles seen in other public health initiatives, where misalignment between research, practice, and policy weakens long-term sustainability. Without a clearly communicated conceptualization, CVI programs risk being co-opted into enforcement-driven models that dilute their public health foundation. This policy insight explores the challenges with definitional and measurement inconsistencies across the field of CVI and what they reveal about broader public health policy challenges. The authors argue that the field must adopt a unified framework that thoughtfully reflects its historical foundations, prioritizes practitioner expertise, and employs evaluation methods that fully capture its impact. By positioning CVI as a pillar of both public health and public safety, policymakers can move beyond reactionary approaches to violence and invest in long-term, community-driven strategies that promote safety and healing.

Introduction

Community violence refers to intentional acts of interpersonal harm occurring in public spaces, disproportionately affecting marginalized communities and contributing to cycles of trauma, instability, and disinvestment. ¹ In response, Community Violence Intervention (CVI) has emerged as a public safety strategy that prioritizes public health and community-generated approaches. While the term “CVI” gained national traction following the passage of the Bipartisan Safer Communities Act, ² which formalized federal investment in these strategies, the work itself is hardly new. Long before CVI became a policy term, Black, Brown, and working-class communities developed their own systems of protection and intervention in response to the structural and interpersonal violence they faced.

The formalization of community violence intervention has frequently marginalized the foundational contributions of grassroots pioneers. As policymakers and funders shape dominant narratives, the leadership and expertise of those who originally built this field are often overlooked. This exclusion creates a disconnect between top-down initiatives and the lived realities of the communities most affected by violence. Recognizing and honoring the lineage of community-led public safety work is not just a matter of historical accuracy, but rather a foundational step toward maintaining the integrity and efficacy of CVI. Without this grounding, the field risks perpetuating ambiguity, diluting impact, and eroding its core principles.

Tracing the Evolution of CVI

The academic foundations of modern violence intervention can be traced to early sociological studies on gangs and urban violence. In the 1920s, Thrasher’s work, The Gang, ³ provided one of the first analyses of youth violence as a social phenomenon rather than a purely criminal issue. Even before Thrasher’s research, reformers like Jane Addams were engaged in community-based responses to violence working directly with immigrant and working-class youth to address the social conditions that fueled gang activity and urban unrest. ⁴ By the mid-20th century, these theoretical insights materialized into structured intervention models. The “detached worker” approach, emerging in the 1950s, embedded outreach workers within communities to build trust and mediate conflicts. ⁵ During this period, Alinsky revolutionized community organizing, emphasizing direct action and empowering marginalized communities to challenge systemic violence and structural inequality. ⁶ Later, scholars such as Klein and Maxson analyzed gang dynamics, showing the limitations of existing prevention, intervention, and suppression strategies while advocating for approaches that addressed the complex social and economic contexts of gang involvement. ⁷

By the mid-1970s, 2 frameworks emphasized the importance of lived experience in violence intervention: Eddie Ellis in New York introduced the credible messenger model, arguing that those who had directly experienced violence were uniquely positioned to serve high-risk individuals, ⁸ while Howard Uller in Los Angeles developed the concept of “license to operate,” underscoring the importance of credibility among gang-involved individuals. ⁹ In the 1980s, comprehensive community justice partnerships (eg, the Spergel Model) also demonstrated the potential of practitioner-led interventions, blending community outreach with broader public safety collaborations.^10,11 However, by the 1990s, public health approaches gained prominence, particularly through Chicago CeaseFire— nor Cure Violence—treating violence as a contagious disease to interrupt its transmission through community outreach. ¹² The term “Ceasefire” has also been associated with focused deterrence strategies, notably in Boston’s Operation Ceasefire, which rely on law enforcement and deterrence tactics, ¹³ contrasting with grassroots-oriented public health models. Throughout these developments, Black and Brown communities played a central role in shaping violence intervention, drawing on long-standing practices of collective action and resistance against systemic harm.

Today, CVI lacks a single, universally accepted definition, with agencies, researchers, and advocacy groups framing it in different ways. While practitioners share consensus on core elements like trust-building and targeted engagement of the highest risk, these varying definitions can hinder implementation and access to funding across regions. Table 1 presents a purposive sample of definitions developed between 2018 and 2024, selected based on their relevance to major federal funding initiatives and national CVI frameworks. The definitions were drawn from key government agencies, advocacy groups, and research centers to illustrate variation across sources shaping contemporary practice. This sample is not exhaustive but highlights definitional similarities and inconsistencies emerging during a period of rapid formalization for the CVI field.

Inconsistent definitions that fail to capture these core elements present profound obstacles to advancing the field. First, they can lead to ineffective policy. Without fully understanding how CVI functions on the ground and across different contexts, policymakers risk crafting mandates and funding restrictions that hinder rather than sustain these efforts. For instance, during the distribution of federal COVID-relief funds, some jurisdictions included traditional law enforcement activities under the label of CVI, inadvertently broadening the term beyond its original focus on community-led, non-carceral strategies. ²¹ This kind of conceptual stretching—where a term is expanded to cover practices that may conflict with its core principles ²² —can create confusion and weaken the policy and funding structures meant to advance genuine CVI efforts. Relatedly, policymakers may focus on scalable and evidence-based models that align with government funding requirements but may not always be feasible or appropriate for every community. At the local level, municipalities risk implementing CVI programs inconsistently. For example, some municipalities adopt enforcement-heavy approaches that blur the line between intervention and surveillance. When policies fail to differentiate CVI from traditional law enforcement approaches, they risk reinforcing the very systems of harm that CVI aims to disrupt.

For the research community, these definitional ambiguities reflect deeper tensions between the priorities of researchers, funders, and practitioners, ultimately undermining the potential to produce actionable, context-sensitive evidence. Without a shared conceptual framework, the research community risks misaligning its inquiries by focusing on metrics and methodologies that may fail to capture the nuanced realities of CVI efforts. This absence of consensus limits our ability to determine what and how to measure, reinforcing a reliance on narrow, quantitative outcomes—such as reductions in homicides and shootings—while overlooking process-oriented and relational measures central to CVI, including conflict mediation, trust-building, quality of life outcomes, and long-term stabilization. Moreover, methodologies like randomized controlled trials, while rigorous when appropriately applied, are often ill-suited to capturing the iterative nature of CVI work. This can result in reductive analyses that align closer with funder expectations than with the lived realities of communities implementing programs. Ultimately, organizations that utilize multi-pronged strategies may struggle to secure funding or validate their approaches thereby limiting understandings of success and sidelining critical questions about how CVI functions as a component of a public safety ecosystem.

Finally, a failure to establish a shared understanding of CVI has serious implications for practice by fundamentally jeopardizing the safety, sustainability, and integrity of the work. When uninformed, CVI practitioners operate within a system that does not fully recognize or support their work, creating confusion about their role and making it difficult for them to establish legitimacy within both institutional and community spaces. Law enforcement may see them as liabilities rather than allies, community members may be skeptical of their autonomy, and funders may impose expectations that distort the work in its highly localized context. In extreme cases, misinterpretations lead to practitioners being harmed or killed, such as in the case of a violence interrupter in Newark, NJ who was arrested while responding to gunfire. ²³ Authorities charged him with obstruction of justice and resisting arrest, consequently exposing the risks practitioners face when their roles are not clearly defined and understood.

Such measurement challenges also hinder the CVI workforce from professionalizing in a way that ensures its long-term sustainability. Without clarity on required skills, core competencies, or best practices, training programs can be inconsistent, and career pathways limited. Many CVI workers enter the field motivated by lived experience, yet there is an absence of structured pipelines for professional advancement. While funders increasingly push for standardized certification, a lack of consensus at this stage risks disconnecting these efforts from frontline realities. This dynamic forces practitioners to navigate an unstable, under-resourced profession with little job security. Moreover, high turnover rates weaken the field, and ultimately make it difficult to build institutional knowledge and sustain meaningful shifts in communities most affected by violence. The lack of investment in workforce development also means that CVI practitioners will continue to be asked to intervene in high-risk situations without sufficient protections, fair compensation, or access to the mental health resources necessary to cope with the trauma of crisis response work.^{24 -26}

Conclusion

The stakes of failing to align on measurement and practice are high. At its worst, the field of CVI could become fragmented and diluted by competing agendas. As a result, the workforce could remain undervalued, unprotected, unsustainable, and treated as an afterthought acknowledged only when they align with institutional priorities rather than being thoughtfully integrated into public safety strategies. This can lead to a weakened foundation that leaves practitioners vulnerable, programs unstable, and interventions misaligned with the needs of the communities they serve. As the field evolves, it must remain accountable to its origins and to the communities that created it. Without this fidelity, CVI risks having its transformative potential go unrealized and becoming another well-intentioned yet misapplied approach to reducing violence.
