通常，用于测量热感觉的量表已被格式化为分类量表（CS）。新兴的是使用CS结合视觉模拟量表（VAS）用于测量热感觉，以提高量表的灵敏度。然而，比较典型CS、标准VAS和CS与VAS组合的报告很少。合并比额表引起了方法和概念问题，但关于不同比额表的优点和局限性的报告不足。本研究通过问卷调查（n = 988）和运动对照实验（17名男性受试者）比较了9分分类量表（9分CS）、VAS和CS结合VAS（图形CS）。我们的研究结果表明，图形CS更密切相关的室内空气温度的休息居民，而不是VAS或9分CS。在热中性区的室内环境中，区分热感觉的敏感性是最大的图形CS。特别是，问卷调查的VAS显示了显着的集群周围的热中性区。对于动态锻炼受试者，平均皮肤温度与图形CS的关系比9分CS更密切。我们的结果表明，对于热感觉的测量，图形CS似乎比9分CS或VAS更有效和敏感，但从方法和概念的角度来看，在结合CS和VAS时，需要考虑许多问题：术语定义、用描述符表达、类别数量、评分长度、单极/双极结构、语言翻译、中心术语、两个锚术语、方向，对上述方法和概念问题进行了讨论。(C)2009爱思唯尔有限公司版权所有。
Typically, the scales for the measurement of thermal sensation have been formatted as categorical scales (CS). Emerging is the use of CS combined with visual analog scale (VAS) for the measurement of thermal sensation to improve the sensitivity of scales. However, reports are rare comparing the typical CS, standard VAS, and combined CS with VAS. Methodological and conceptual issues are arising with the combining of scales, but there are insufficient reports about the advantages and limitations of different scales. The present study compared 9-points categorical scale (9pts CS), VAS, and CS combined with VAS (graphic CS) through a questionnaire Survey (n = 988) and a controlled experiment during exercise (17 male subjects). Our results showed that graphic CS was more closely related to indoor air temperature for resting residents rather than VAS or 9pts CS. Around thermal neutral zone indoor environments, sensitivity to discriminate thermal sensation was the greatest for graphic CS. In particular, questionnaire responses to VAS showed a remarkable clustering around the thermal neutral zone. For dynamic exercising subjects, mean skin temperature was more closely related to graphic CS than 9pts CS. Our results indicated that graphic CS seemed to be more valid and sensitive than 9pts CS or VAS for the measurement of thermal sensation, but there are many issues to be considered when combining CS and VAS from the methodological and conceptual view points: definitions of terms, verbalizing with descriptors, number of category, scoring length, unipolar/bipolar construction, language translation, central terms, both anchor terms, orientation, color, etc. The above methodological and conceptual issues were discussed.
