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.

The purposes of this study were ; 1) to assess the level of pain and to identity the varieties and the degree of pain-related behavior, 2) to measure the level of correlation between the level of pain and the degree of pain?related behavior, 3) to test the correlation between the Korean Pain Rating Scale (KPRS) and Graphic Rating Scale(GRS), and 4) to gather data relevant to the Socio-demqgraphic status of the subjects. The level of pain was measured by KPRS and GRS developed by the researchers. The KPRS consists of three dimensions ; the sensory, the affective and the miscel laneous and the GRS of two separate scales ; the intensity scale and the unpleasantness scale. Of the 2,025 who had visited orthopedic and neurosur-gical out-patients department of 11 university hospitals in various districts of Korea with the episode of joint pain, 405 subjects were self-selected by responding to the data gathering tools and questionaires mailed. The results are summaried as follows; 1. Maale(217, 53.6%) exceeded female patients( 188, 46. 4%) in number and the onset of joint pain was more prevalent in the age groups of the 20s and the 30s. 160(39.5%) had been hospitalized for the treatment of, and 87 (21.5%) had retired because of the joint pain. 2. Mean pain score measured by KPRS was 128.31 (ran ge; 0 1.344.8); mean sensory score was 43.23(range: 0-645.88%), mean affective score was 46.09(range; 0 356.72), and mean miscellaneous score was 39.99 (range; 0-341.68). Mean pain scores measured by GRS were; sensory intensity score; 109l(range: 0-200) and distress score; 99.1 (range: 0 200). 3. The prevalent sites of joint pain revealed to be the right knee joint(203: 50.1%), left knee joint(181(44. 7%), left ilium ( 147,36.3%). lumbar regir,n(106: 26. 2%), hip joint(92: 22.7%) and the ankle(84; 20.7%). 4. The average sleep hour was 6.8hours per day and the average rest hour during the day hours was 3.3hours (range 0-20). 5. The average duration of suffering from bint pain was 49.1 months. 6. Most of the subjects(298; 73.6%) used some sorts.

The purposes of this study were; 1) to gather data relevant to demographic features, major main management practices, and the level of impairment of the activities of daily living (ADL) of patients with back pain, 2) to test the sensitivity of the Korean Pain Rating Scale and the Graphic Rating Scales, and 3) to identify indirect indicators of back pain by analysing pain related-bebaviors. The level of pain was measured by Korean Pain Rating Scale(KPRS) and Graphic Rating Scales(GRS) developed by the reserchers. The GRS consists of two dimensions; the pain intensity (sensory) and unpleasantness (affective) measures. Of the 1,650 diagnosed back pain patients, from January 4 through June 30, 1987 by visiting outpatients' clinics of orthopedic and neurosurgical departments at 11 university hospitals in different districts of Korea, 330 men and women patients were self-selected by responding to the mailed questionnaires. The results were summarised as follows; Male exceeded female patients in number and onset of back pain were more prevalent in the age groups of 20s and the 30s. The average duration of suffering from the pain were 11 months, sixty three (19.1%) of the subjects retired from their jobs, one third(36.7%) have been hospitalized for the treatment of back pain. In two thirds(64.8%) of the cases pain was characterized as lower back pain. The average sleep hour was 6.8 hours per 24 hours and the average rest hour during the day was 3.3 hours. The mean percentage of pain measured by GRS was higher than that of KPRS. The level of sensory intensity as well as the affective level of pain measured by KPRS and GRS were not highly correlated (sensory intensity r=0.4986, affective r=0.5029) which indicated low discriminative power. On the other hand, intercorrelation between sensory and affective dimension measured by KPRS and GRS showed moderate interrelation(r=0.7247; r=0.7899). One-third(32.5%) of the subjects complied with the hospital prescribed treatment while the other one-third(31.5%) depended on self-remedy and traditional practices, and the last one-third did not imply any pain management practices. The following 6 pain-related behaviors such as length of hospitalization, rest hour during day hours, varieties of pain management practice implied, number of pain sites, need for ADL and discomfort accompanied by ADL revealed to be important indicators of back pain. An investigation of sociodemographic features of patients with back pain in a larger context, i.e. with bigger number of respondents is recommended.Tests for construct validity of KPRS, i.e. factor analysis is further recommended.
