Joplin’s own Mark Liston, PhD, professional counselor with JoMo Counseling and educational psychologist, worked with award-winning psychologist Ed Diener, PhD, to develop a valid scale to assess our well-being. The Flourishing Now Scale (© 2012 Mark Liston) is used in over 30 states and 8 other countries. Why so popular? First, it’s short with only eight questions. Second, in 2 minutes, you can get a snapshot of your well-being.
