Dietetic performance evaluation: establishment of validity and reliability

Performance evaluation as conducted among a number of raters using several evaluation tools requires the qualities of content validity and interrater reliability to be fair and effective. A procedural model was tested and implemented by faculty and students in the Coordinated Undergraduate Program (CUP) at the University of Tennessee, Knoxville. A checklist for evaluation of employee counseling techniques achieved an intraclass correlation of 0.72 when used by clinical instructors in a series of workshops. The procedure included development of a form, its use in a standardized situation, discussion, calculation of intraclass correlation, and review. The model is suggested for implementation in any program from which established validity and reliability in evaluation are desired.
