The Adult-Oriented Sport Coaching Survey (AOSCS) assesses psychosocial coaching practices for coaches who work with adult athletes. The AOSCS can be used as a self-assessment tool for coaches’ professional development, but there is a need to better understand its relevance for coaches. The purpose of this study was to explore coaches’ perspectives of the AOSCS as a self-assessment tool for reflecting, intuitively appraising, and provoking elaborations on contextually embedded psychosocial practices when coaching adult athletes. Thirteen Canadian coaches (nine women/four men, aged 59–78 years) completed the AOSCS prior to watching a webinar regarding the research on coaching Masters athletes and the development of the AOSCS. Each was subsequently shared a copy of their AOSCS results and interviewed about their perceptions of the relevance and utility of the AOSCS. Interviews were analyzed using reflexive thematic analysis, which resulted in three higher order themes (relevance of the AOSCS, using the AOSCS, and input from others) with six subthemes. The coaches see the AOSCS as provoking meaningful coach reflection, introspection, and learning intrapersonal coaching knowledge that serve ongoing coach development. As such, this paper outlines evidence with respect to the prospective relevance and practical utility of the AOSCS.
