A behaviorally based appraisal of coaching performance in women's athletics at Michigan State University

The purpose of this study was to construct a multitrait multirater model for the appraisal of the 10 head coaches in the women's athletic program at Michigan State University in 1977-78. The resulting instrument was a behaviorally anchored rating scale (KBARS) consisting of 10 dimensions. The construction of the KBARS involved members of the rater population. They submitted 623 examples of effective and ineffective coaching behaviors. These incidents were refined to 299 statements. On the basis of the literature pertaining to coaching and the content of these incidents, 12 categories or dimensions of coaching performance were defined. A stratified sample of 43 raters-to-be allocated each statement to a dimension and assigned the item a numerical value from one to seven. In order to be included in the final KBARS, items and dimensions had to meet modal assignment, variability, and agreement criteria
