A Methodological Study of Forced-Choice Performance Rating.

摘要

The objective of the present study was a relative evaluation of six different kinds of forced-choice performance rating forms with respect to validity, reliability, biasability, and the degree to which raters liked different forms. The kinds of forced-choice forms used in the investigation varied as to the content of the blocks of statements and as to the directions which were given the raters. Of the forms used in this experiment, those in which the blocks were composed of four favorable-appearing statements, from which the rater was to choose either the two most descriptive, or the most and the least descriptive, were generally superior. The inclusion of both favorable and unfavorable statements in the same block appears to be an inferior method of constructing forced-choice forms.
