About 70% of youth athletes drop out of sport by age 13. Self-determination theory has been utilised to investigate athletes’ motivations for behaviours including sport persistence (i.e. continuation) and suggests that the coach can be an influence on such motivations. Basic need fulfillment via interpersonal coaching behaviours, the coach-athlete relationship (CAR), and intentions to continue sport participation have been examined independently and in various combinations and directions, but these variables have not been examined collectively in this manner. The purpose of this study was to determine if CAR quality mediates the relationship between interpersonal coaching behaviours and intentions to continue sport participation. Surveys were administered to 148 athletes ages 11 to 16 from organised sports teams. No significant indirect effects of mediation could be established. However, there was a significant and direct effect of competence-supportive behaviours on intentions ( β = .341, p < .001). Overall, the total effects model was significant ( F(1,146) = 18.762, p < .001, adjusted R 2 = .114). Significant positive relationships were shown among supportive coach behaviours and CAR quality in addition to CAR quality and intentions. Negative relationships were demonstrated among thwarting coach behaviours and CAR quality. Results support that coaches’ competence-supportive behaviours can positively impact CAR quality and intentions to continue sport participation in youth athletes.
