Explore an innovative approach to school-based wellbeing education in this inaugural professorial lecture. Learn how to design programs that feel like a TREAT (Tangible, Relevant, Evidence-based, Alluring, and Transformational) rather than a treatment plan. Discover strategies to make wellbeing education more engaging and effective for young people, incorporating best practices from health, sport, wellbeing science, technology, and education. Examine the TREAT framework and its potential to equip, inspire, and empower students to actively shape their mental health and well-being. Delve into topics such as prosocial behaviors, experience sampling methodology, biofeedback, active constructive responding, and relaxation techniques. Gain insights into creating mind fitness hubs, implementing wellbeing education at systems and macro levels, and inspiring long-lasting change in youth mental health approaches.
