Abstract

• The Purposes of this study were : 1) to evaluate validity of a pain rating scale using the level of correlation between the Korean Pain Rating Scale(KPRS), Short-From KPRS(SKPRS) and the Graphic Rating Scale(GRS). 2) to identify sensitivity of the scale using pain behavior of patients with chronic pain Of the 2025 patients with chronic pain who visited the orthopedic and neurosurgical out-patients departments of 11 university hospital in various districts of Korea, 520 subjects wee selected through convenient sampling and responded to the questionnaires by mail. The results of the study can be summarized as follows ; 1. The mean pain score measured by the KPRS was 444.85 : the mean sensory score was 209.47, the mean affective score, 147.63 and the mean miscellaneus score. 87.85. The mean pain score measured by the GRS was 20.11 : the mean sensory intensity score, 10.54. and the mean distress score, 9.57. 2. The average number of hours of rest during the day was 3.3, the average score of discomfort in carrying out ADL was 99, the average frequency of pain relieving practices was 3.0 the average number of pain sites was 3.6. 3. The most sensitive scale to differentiate each group was the GRS, the KPRS and SKPRS were less sensitive than the GRS. 4. The intercorrelation between the KPRS total score and the GRS score(.500) as well as that of the SKPRS score were highly correlated(.652), but intercorrelation between the SKPRS score and the GRS score(.172) was not high. Based on the above results, it was found that the SKPRS must be studied further to obtain validity.
