The accuracy of information derived from a visual analogue scale has been assessed by comparing the measured grip strength of 100 subjects against their estimate of grip strength scored on a visual analogue scale. There was relatively poor correlation between the measured and assessed values, suggesting that similar inaccuracies may occur when the scales are used to assess subjective phenomena.
通过将100名受试者的测量握力与其在视觉模拟量表上所记录的握力估计值进行比较,对源自视觉模拟量表的信息准确性进行了评估。测量值与评估值之间的相关性相对较差,这表明当使用这些量表来评估主观现象时,可能会出现类似的不准确情况。
