N2 - Self-determination theory (Deci & Ryan, 2000) has been frequently implemented as a framework to examine the mechanisms that underpin change in a variety of health behaviors. This study aimed to explore the mechanisms responsible for mental health, physical activity intentions and subsequent behavior by testing an SDT based motivational model in an exercise setting. Participants (n = 145) who were recruited by health and fitness advisors (H&FA) across a major UK city, were individuals who completed a 3 month exercise on referral program (ER).
