Elite sport requires a great amount of time deliberately devoted to training and to optimize improvement (Ericsson, Krampe, & Tesch-Römer, 1993). Coaches are important social influences for an athlete (e.g., Smith & Smoll, 1996). Elite athletes spend more time with coaches than with other potential sources of influence. Therefore, the main purpose of the present study was to study the coach as a moral influence. The review of literature indicated that coaches are moral influences for their athletes. However, this evidence has to be considered with caution because of the characteristics of the designs of the studies (e.g., theoretical framework, methodology). Based on the evidence provided by the literature review, two qualitative case studies were conducted in an attempt to address current gaps in literature. For the pilot study, 7 elite coaches that had been athletes themselves were sampled and for the main study 10 coaches with the same characteristics were sampled. Interviews were conducted and data was inductively analyzed using Grounded Theory strategies for analysis (Corbin & Strauss, 2008; Strauss & Corbin, 1998). In addition, the dimension of the Coaching Efficacy Scale evaluating coaches’ self-efficacy to instil morality in their athletes was used in the main study (Feltz, Chase, Moritz, & Sullivan, 1999). Evidence from these research efforts generated four major findings. First, coaches are important moral influences. Participants in this study recognized their past coaches had a moral influence over them. Also, these participants acknowledged that as coaches, they had the moral obligation to watch over morality within the team. Second, coaches’ iv conceptions of morality entail four dimensions: a) “elite sport involvement”; b) “game”; c) “interaction with others”; and d) “self-related”. Third, participants’ past moral influences are reflected in their conceptions of morality, and captured in their current coaching practices. Past coaches are models from which current coaching interventions are built. Finally, a better understanding of moral influences in sport can be attained if different theoretical contributions are considered together. Important factors concerning moral influence are a coach-athlete relationship and culture. Findings from this thesis have addressed a knowledge gap in the field. This qualitative design has provided valuable information concerning the factors that enable or prevent moral influences, and the environment where moral influences take place. Also, this data has provided insight on potential targets in the design of future educational coaching interventions to sensitize coaches concerning morality. Future research endeavour should continue build upon this thesis by considering other populations (e.g., athletes) and other sport contexts (e.g., recreational). The relationship between coachathlete relationship and culture needs to be examined in-depth.
