| The primary purpose of this study was to examine the role of efficacy beliefs in predicting perceptions of relationship quality (i.e., closeness, commitment, and complementarity) within coach—athlete dyads. Data from 63 youth athletes and their coaches were analyzed using actor—partner interdependence models and revealed actor effects for self-efficacy on complementarity (for both dyad members) and closeness (for coaches only). A number of actor and partner effects emerged for other-efficacy and relation-inferred self-efficacy. However, the magnitude, and in some cases the direction, of these relationships were moderated by the person’s dyadic role. The findings are discussed with respect to interdependence in coach—athlete relationships. |
