Abstract
The Visual Analogue Scale 8 (VAS8), consisting of eight linear scales, has been developed to measure health-related quality of life (HRQoL) in chronic obstructive pulmonary disease (COPD) patients. The purpose of this study w as to examine the validity and responsiveness of the VAS8. First, HRQoL was assessed in a cross-sectional study with the VAS8 and the St George's Respiratory Questionnaire (SGRQ) in 46 COPD patients. Relations hips between the VAS8 and various physiological parameters were examined. S econd, in a longitudinal study. changes in HRQoL scores after pulmonary reh abilitation were evaluated in 29 COPD patients. The total VAS8 scores showed a weak correlation with vital capacity and max imal inspiratory pressure and a moderately strong correlation with 6-min wa lking distance and dyspnoea rating. The total VAS8 score showed a significa nt correlation with each SGRQ score. Furthermore, almost every VAS8 and SGR Q score improved significantly after pulmonary rehabilitation. The change i n the total VAS8 value showed a strong correlation with that of the SGRQ. The VAS8 is well-suited to assess HRQoL in COPD patients. Visual analogue s cales are generally useful in measuring HRQoL in COPD patients, and the VAS 8 is particularly beneficial because or its case of use.
