Visual Analogue Scales (VAS) provide a simple technique for measuring subjective experience. They have been established as valid and reliable in a range of clinical and research applications, although there is also evidence of increased error and decreased sensitivity when used with some subject groups. Decisions concerned with the choice of scoring interval, experimental design, and statistical analysis for VAS have in some instances been based on convention, assumption and convenience, highlighting the need for more comprehensive assessment of individual scales if this versatile and sensitive measurement technique is to be used to full advantage.
视觉模拟评分法（VAS）提供了一种测量主观体验的简单技术。尽管有证据表明，在某些受试群体中使用时会增加误差并降低敏感性，但在一系列临床和研究应用中，它们已被确立为有效且可靠的方法。在某些情况下，与VAS评分区间选择、实验设计和统计分析相关的决策是基于惯例、假设和便利性做出的，这凸显了如果要充分利用这种通用且敏感的测量技术，就需要对各个量表进行更全面评估的必要性。
