THE PRACTICALITY OF BEHAVIORAL OBSERVATION SCALES, BEHAVIORAL EXPECTATION SCALES, AND TRAIT SCALES
研究比较了行为观察量表、行为期望量表和特质量表在区分绩效、客观性、反馈、培训需求和易用性方面的实用性，发现行为观察量表最受管理者和下属偏好，且更易在法庭上辩护。
The practicality of three appraisal instruments were measured in terms of user preference, namely, behavioral observation scales (BOS), behavioral expectation scales (BES), and trait scales. A questionnaire containing items pertaining to differentiating good from poor performers, objectivity, providing feedback, suggesting training needs, and ease of use was administered to managers and their subordinates. In all instances, BOS were preferred to BES, and in all but two instances, BOS were viewed as superior to trait scales. Trait scales were felt to be as good if not better than BES. A second questionnaire administered to attorneys indicated that BOS would be easier to defend in the courtroom than either BES or trait scales.
