Abstract

This study extends validity evidence for the Coaching Efficacy Scale (CES; Feltz, Chase, Moritz, & Sullivan, 1999) by providing an evaluation of the psychometric properties of the instrument from previously collected data on high school and college coaches from United States. Data were fitted to a multidimensional item response theory model. Results offered some supporting evidence concerning validity based on the fit of a multidimensional conceptualization of coaching efficacy (i.e., motivation, game strategy, technique, and character building) as compared to a unidimensional conceptualization of coaching efficacy (i.e., total coaching efficacy), the fit of the majority of items to the measurement model, the internal consistency of coaching efficacy estimates, and the precision of total coaching efficacy estimates. However, concerns exist relating to the rating scale structure, the precision of multidimensional coaching efficacy estimates, and misfit of a couple of items to the measurement model. Practical recommendations for both future research with the CES and for the development of a revised instrument are forwarded.
