The Community Engaged Research E-Library, part of the Community Connections for Health Translation (CCHT) Pillar and the Capacity Building and Systems Change Domain, leverages existing local, regional, and national resources around community engagement and community-engaged research (CEnR). The following guides equip both community-based organizations (CBOs) and researchers with training, videos, and other capacity-building tools to fully engage in CEnR. Through CEnR, CBOs and universities can form mutually beneficial, robust, and collaborative partnerships to advance community and population health.
