Youth Participatory Action Research Projects (YPAR)

SNAP-Ed InterventionsCalifornia

Intervention Reach and Adoption

YPAR primarily targets middle and high school youth (ages 12-18) in school and community settings. YPAR projects may also target upper-elementary-aged youth. Youth work with an adult ally on projects related to nutrition and physical activity issues in their school or community. YPAR projects have been implemented across California in both urban and rural areas.   Settings: Community-wide, Schools  Age/Population Group: Middle School, High School Race: All Ethnicity: All

Intervention Components

YPAR projects consist of a project coordinator, adult ally, and youth team. Due to the nature of the approach, no two YPAR projects will look the same.  YPAR is based on a variety of social learning, popular education, health promotion, and youth development theories. Key principles of the approach include:  Youth opinions are solicited, respected, and applied.  Youth identify their own issues, problems, and possible solutions.  Youth initiate project ideas, carry out planning, and goal setting.  Youth drive the process and are involved in all states of decision-making.  Youth teach other youth.  YPAR utilizes a participatory action research framework that includes the following steps:  Identify the issue or problem.  Define what is known about the issue or problem.  Identify what additional information is needed to understand the issue.  Determine what methods and approach will be used to collect this information and then work together as a team to accomplish this.  Use the information for education, understanding, strategic action, and/or community change.

Intervention Materials

CalFresh Healthy Living Statewide Training team comprised of the California Department of Public Health and CalFresh Healthy Living, University of California provides training and technical assistance and resources to help organizations implement YPAR. Training materials include information on topics such as planning and launching the program, guidelines for developing research questions and methods, sample surveys and interview guides, photovoice resources, information on analyzing and making meaning of data, tips for preparing presentations, and sample forms for recruiting youth.    Training resources can be accessed through the CalFresh Healthy Living Statewide Training,  Youth Engagement webpage  and the  CalFresh Healthy Living, University of California Youth Engagement Initiative webpage .   Technical assistance through peer-to-peer exchanges is also available to support organizations learning best practices in implementing YPAR.

Evidence Summary

Case studies have been conducted on numerous YPAR projects throughout both urban and rural areas of California. Positive results related to improvements in nutrition and physical activity behaviors among youth, their peers and families; increased access to fruits, vegetables and clean drinking water in schools and communities; new skills and exposure to new experiences acquired in youth; and expansion of successful projects to additional sites, new partners, additional funding, media attention, and other health improvement efforts.   Evidence Base: Practice-tested
