An intervention to train group exercise class instructors to adopt a motivationally adaptive communication style: a quasi-experimental study protocol

Abstract

Introduction: According to self-determination theory (SDT), individuals in position of authority can have a powerful impact on the motivation of the individuals they instruct via the type of communication style they use. This paper describes (a) the rationale for and development of an SDT-based motivation communication training package for group exercise instructors and (b) the design and protocol for an intervention study to evaluate the implementation of this intervention. Methods and analysis: Fifty indoor cycling class instructors will be assigned to either an intervention group (n = 25) or a control group (n = 25). Over a 10-week period, instructors in the intervention group will complete a multiphase SDT-based communication training programme. The evaluation package will comprise qualitative and quantitative assessments of the motivationally relevant features of the class environment as well as motivation and well-being variables, undertaken by both exercise class members and instructors.
