The 21-Day Purpose Challenge was delivered in August of 2015, by Brandon Peele and the Planet Purpose team. Dr. Gleb Tsipursky, PhD, Professor at Ohio State University, and Planet Purpose Science Advisor, administered the Meaning and Purpose Questionaire evaluating the self-reported purpose meaning before and after having taken the Challenge. Most promising was the 1.91 differential improvement (on a scale of 1-10) in the agreement with the statement "I am satisfied with the sense of meaning and purpose in my life."
