Wancantognaka Project (The Generosity Project) (TGP)

2026年11月10日 更新者:Katie M Edwards、University of Michigan

Development and Rigorous Evaluation of Culturally Grounded Crime Prevention Through Environmental Design for Lakota Youth on a Rural Reservation: Wancantognaka Project (The Generosity Project [TGP])

The goal of this study is to examine whether a place-based, community-led, and culturally grounded Crime Prevention Through Environmental Design (CPTED) intervention can prevent and reduce interpersonal community violence (ICV) among youth living on the Pine Ridge Reservation. The study will evaluate The Wancantognaka Project (The Generosity Project; TGP), which combines community-led environmental improvement projects with culturally grounded youth programming. Youth ages 13-19 will participate in sessions led by Lakota Elders, Traditional Healers, and/or Traditional Knowledge Keepers focused on leadership, cultural teachings, community engagement, and implementing projects to improve community spaces.

The primary aims of the study are to: (1) Develop and implement TGP in partnership with community members; (2) Assess implementation, community acceptance, perceived impact, and costs; (3) Examine whether TGP increases protective factors and reduces risk factors for interpersonal violence among youth in the intervention community compared to youth in a similar comparison community not receiving the intervention; and (4) Examine whether TGP reduces rates of community violence compared to the comparison community.

調査の概要

詳細な説明

Interpersonal community violence (ICV), including physical assaults, violence between groups, and threats or use of weapons, is a significant public health concern among American Indian/Alaska Native (AI/AN) populations, including youth. Lakota youth living on the Pine Ridge Reservation face substantial challenges related to community violence. Despite growing knowledge about factors associated with community violence, research evaluating culturally grounded violence prevention approaches in Tribal communities remains limited.

Crime Prevention Through Environmental Design (CPTED) is a promising approach to preventing community violence. CPTED combines improvements to physical environments (e.g., lighting, community gardens, and improvements to shared spaces) with social strategies (e.g., community engagement, relationship building, and collective action) to create safer and more supportive communities. Busy Streets Theory (BST), which informs this study, emphasizes community participation, local ownership, and strengthening social connections through community-led improvements to neighborhood environments. This approach aligns with Lakota cultural teachings, including honoring Unci Maka (Mother Earth), Wacantognaka (generosity), Mitakuye Oyasin (all are related), Wolakota (being a good relative), and Wakanyeja Kin Wakan Pi (children are sacred).

The Wancantognaka Project (The Generosity Project; TGP) is a community-led, culturally grounded CPTED intervention designed to prevent and reduce interpersonal community violence among youth ages 13-19 on the Pine Ridge Reservation. The project integrates community-designed environmental improvements with culturally grounded youth programming led by Lakota Elders, Traditional Healers, and/or Traditional Knowledge Keepers. Youth programming will focus on leadership, cultural teachings, community engagement, and participation in projects intended to strengthen community spaces and connections.

The study uses a community-based participatory action research (CBPAR) approach, engaging youth, Elders, Traditional Healers, Traditional Knowledge Keepers, community members, and interdisciplinary researchers throughout intervention development, implementation, and evaluation. A Community Advisory Board and/or Program Steering Committee will help guide project activities to ensure they reflect community priorities, cultural teachings, and local knowledge.

The study has four primary aims:

  1. Intervention Development and Implementation:Collaboratively develop and implement TGP, including culturally grounded CPTED projects and youth programming informed by community priorities and Lakota cultural teachings.
  2. Implementation Evaluation: Examine intervention implementation, community acceptance, perceived impact, and costs, using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.
  3. Youth Outcomes: Evaluate whether TGP increases protective factors (e.g., sense of community, positive cultural identity, social support, and positive youth development) and reduces risk factors and behaviors associated with interpersonal violence (e.g., substance use, delinquency, and violent behaviors) among youth in the intervention community compared to youth in a similar comparison community that does not receive TGP.
  4. Community Violence Outcomes: Evaluate whether TGP reduces rates of community violence, including violence involving youth ages 13-19, in the intervention community compared to the comparison community.

The study uses a longitudinal, quasi-experimental design to compare youth and community-level outcomes between an intervention community and a demographically similar comparison community on the Pine Ridge Reservation. Youth will complete surveys at baseline, immediately following the intervention, and at 6- and 12-month follow-ups. Community-level violence outcomes will be assessed using police incident data collected before and after intervention implementation.

Findings will contribute to understanding the feasibility, acceptability, implementation, and potential effectiveness of culturally grounded, community-led environmental approaches to preventing interpersonal community violence in Tribal communities.

実験的:Intervention

The intervention group will participate in the The Wancantognaka Project (The Generosity Project; TGP) for Treatment Community on the Pine Ridge Reservation

The Wancantognaka Project (The Generosity Project; TGP) for Treatment Community will involve programming sessions for youth taught by Lakota Elders, Traditional Healers, and/or Traditional Knowledge Keepers. TGP will also involve planning and implementing CPTED projects in residential areas. Example CPTED projects include building inipis (sweat lodges) for ceremony and culturally-grounded murals.

介入なし:Control

The control group includes youth from Control Community, a demographically similar community to Treatment Community. The control group will not receive the TGP intervention.
