Role Ambiguity, Role Efficacy, and Role Performance: Multidimensional and Mediational Relationships Within Interdependent Sport Teams

Male secondary school rugby players (N = 271) participated in a study examining role ambiguity, role efficacy, and role performance. A multidimensional measure was used to assess 4 manifestations of role ambiguity in offensive and defensive contexts. Multiple role ambiguity dimensions explained variance in efficacy and performance. Consistent with theorizing by A. Bandura (1997) and R. L. Kahn, D. M. Wolfe, R. P. Quinn, J. D. Snoek, and R. A. Rosenthal (1964), negative relationships observed between role ambiguity and role performance were mediated by competence (role efficacy) beliefs. Findings support the multidimensional operationalization of role ambiguity and role efficacy as a generative mechanism through which role ambiguity can affect role performance.
