On September 18, 2019 NCCOR hosted a Connect & Explore webinar on the Measures Registry Learning Modules: Helping You Understand Measurement Concepts and Approaches for Diet and Physical Activity Research. NCCOR’s goal in introducing these Learning Modules is to provide a useful resource for those in the field. The Modules highlight key concepts from the four domain-specific Measures Registry User Guides in four 15-minute videos, making it easier to understand measurement issues in the four major domains of the Measures Registry: individual diet, food environment, individual physical activity, and physical activity environment.The webinar highlighted the modules and provided an opportunity for questions for the authors. Speakers included Dr. Jordan Carlson, Dr. Sharon Kirkpatrick, Dr. Leslie Lytle, and Dr. Gregory Welk.
