It may not always be obvious, but mental health is a highly contested concept, and one that has evolved considerably over the years. Are we on the cusp of the next phase in mental health's evolution, and what might this look? Ken Thompson, clinical associate professor of psychiatry at the University of Pittsburgh and member of the Hogg Foundation's National Advisory Council, has some strong feelings on the subject. In this episode, he traces the lineage of our current understanding of mental health, and where he believes it should go next. Sheila Savannah, director of the Oakland-based Prevention Institute, joins us for the second segment where she offers some timely reflections on the fusion between population health and community health.
