Using delphi consensus methods to understand which physical activity behaviour change theories should be taught to Canadian undergraduate students

Abstract

While theories of physical activity (PA) behaviour change are taught to undergraduate students in a range of programs, there is little guidance on which theories should be taught prior to graduation. Aim: To determine which PA behaviour change theories are recommended to be taught to undergraduate students in PA and/or exercise science by the time they graduate. Methods: A Delphi consensus exercise was completed by instructors from across Canada who taught PA behaviour change to undergraduate students. In Round 1, 18 professors completed an online questionnaire to generate a list of PA theories taught. In Round 2, 15 instructors indicated their level of agreement using an 11-point Likert scale as to whether the theories from Round 1 should be taught. In Round 3, 12 instructors were presented a refined list of theories that received high consensus in Round 2 (Mean Score: >7 and rated >7.0 by >66% of participants) and indicated their level of agreement. Results: Round 1 identified 39 theories. After Round 2, 9 theories met consensus guidelines which was further refined to 5 theories in Round 3. However, interclass correlations statistics revealed little consistency in theory ratings. Conclusions: A wide range of theories are taught to undergraduate students and there is a lack of consensus among experts as to which theories should be taught to students. Findings will inform the instruction of behavior change theories in PA and/or exercise science at an undergraduate level.
