Abstract
This study was conducted to establish a pain scale that would express grade, duration, frequency, and time as well as QOL (sleep, appetite, medication, and work habits). The scale was examined for potential application to physical therapy.
For 105 patients, reproducibility and reliability of the scale were evaluated by the test-retest, split half and parallel test methods.
The test-retest indicated r=0.92 in the pain scale, the split half method indicated α=0.49 in the pain states and α=0.64 in the QOL, and the parallel test showed pain states vs VAS is r=0.4 and QOL vs VAS is r=0.56 in this study.
Multiple regression analysis was carried out on the pain scale. The pain states were related to medication (β=0.252), mode (β=0.229) and sleep (β=0.206) (R2=0.54) and then medication was related to appetite (β=0.258), work(β=0.221) (R2=0.4).
These results clearly demonstrate the reliability of the present pain scale and its applicability to clinical situation.
