用视觉类比量表法对国人目测能力的观察

VISUAL MEASUREMENT ABILITY OF CHINESE PATIENIS WITH VISUAL ANALOGUE SCALE

用视觉类比量表法(VAS)对50例病人进行了目测能力的观察。结果显示:在不同方向、不等距离的目测误差均值在1.11～3.71mm;方向对误差无影响(F=0.2879,P>0.05);各距离之间差异有高度显著性(F=23.289,P<0.01);60岁以上老年人误差较大(P<0.05),但性别之间差异无显著性。研究提示,国人具有良好的目测能力,传统的VAS同样适应于我国病人。

The purpose of this study was to evaluate the visual mensurement ability of Chinese patients in the use of VAS. The trial was processed in 50 patients aged from 11～70 years old without premedication. Patients were given nine papers printed 36 lines(10cm long, in four directions) and were asked to make a mark on each line 1～9cm from 0 boundary of the line on the 9 papers respectively. Forty-eight patients successfully completed the trial. The means of the absolute errors of the different directions and distances are smaller ranged from 1.11～3.71mm. No significant differences were found between 4 directions(P>0.05). The were significant differences among 9 distances(P<0.01). The absolut errors were larges in the elderly(P<0.05), but weren't affected by sex. The authors conclude that visual measurement ability of Chinese be suited to the use of VAS.
