Technology-mediated interventions to promote physical activity are growing in popularity and appear to be effective for supporting continued adherence for some people. Some of this efficacy may be related to the cultivation of motivation that is self-determined (i.e., autonomous), which is posited to arise from the satisfaction of three basic psychological needs: competence, relatedness, and autonomy. The Peloton Instructor Needs-Supportive Coaching (PINC) tool was used to code 80 Peloton cycling classes across 4 different class types (Beginner, Power Zone, Groove, and High-Intensity Interval Training) to quantify the frequency of needs-supportive and needs-indifferent coaching within a class. We also provide an example of a pilot study using the tool to test the association between needs-supportive coaching and intrinsic motivation. This dataset provides the valid survey data used in the pilot study analysis to test the association between needs-supportive coaching and intrinsic motivation.
