Supervisor versus Observer: Enhancing the External Validity of Laboratory Performance Appraisal Studies

摘要

This research evaluated differences in the psychometric quality of supervisor vs. observer performance ratings. Specifically, type of rater (supervisor vs. observer) and type of instructions (rating vs. neutral instructions) were manipilated in a 2 x 2 factorial design to compare the traditional laboratory performance appraisal approach with a more realistoc experimental design. Results indicated supervisors demonstrated more halo and leniency error in rating subordinates behavior than did observers. Type of instructions given to the raters had no effect. (AUTHOR)
