Small moments can make a big difference in how children feel and function. This webinar provides foundation information that guides the implementation of all aspects of Every Moment Counts. Participants will learn about positive mental health and how to apply a multi-tiered approach to mental health involving universal promotion, targeted prevention, and individualized intervention. Practical examples of how to embed evidence-based mental health promotion strategies throughout the day (classroom, lunch, recess, after-school) will be provided. Also included is a brief review of the model programs (Comfortable Cafeteria, Refreshing Recess, Calm Moment Cards, Making Leisure Matter), website resources, and how to build capacity of interdisciplinary teams to do this work. This is the first of a 5-part series on the Every Moment Counts’ initiative.
