This paper extends the discussion by Shigeno and colleagues (2019, The Coach’s Role in Creating Moral Group Norms in Youth Sports. International Sport Coaching Journal), who emphasized the importance of coaches’ understanding of athletes’ character and of teaching character in sport. The purpose of the present paper is to (a) provide a discussion of how character in sport can be defined and conceptualized from a multidimensional perspective and (b) to present a valid and practical tool for measuring multidimensional character in sport. The instrument can be used by coaches to assess athletes’ character in order to help them develop core values and standards of acceptable behaviors as well as ethical and morally responsible behaviors on and off the field. Further considerations and future directions related to examining athletes’ character in sports are discussed.
