描述者差异量表（DDS）将心理物理学原理应用于临床疼痛评估。对于评估的每个疼痛维度，它包含12个描述项。对于每一项，受试者指出他们的疼痛是否与锚定描述符所暗示的程度相等，或者在10分图形量表上大多少或小多少。该方法允许收集多个响应，减少缩放误差，并评估疼痛程度和缩放一致性。91例患者完成了感觉强度和不愉快的形式的DDS在1和2小时后，手术拔除下第三磨牙。结果表明，DDS满足标准的心理测量学标准的可靠性，客观性和项目的同质性。发现的系数满足标准的心理测量标准，消除不一致的配置文件后，提高。
The Descriptor Differential Scale (DDS) applies psychophysical principles to clinical pain assessment. It contains 12 descriptor items for each pain dimension assessed. For each item, subjects indicate if their pain either is equal in magnitude to that implied by the anchoring descriptor, or how much greater or lesser on a 10-point graphic scale. The method permits collection of multiple responses, reducing scaling error, and assesses both pain magnitude and scaling consistency. Ninety-one patients completed the sensory intensity and unpleasantness forms of the DDS at both 1 and 2 h after surgical extraction of a lower third molar. Results show that the DDS satisfies standard psychometric criteria for reliability, objectivity and item homogeneity. The coefficients found satisfy standard psychometric criteria and improve after elimination of inconsistent profiles.
