Abstract
Quality of life is an important patient-reported outcome of rheumatoid arthritis (RA) in addition to structural and functional outcomes. The RAQoL (Rheumatoid Arthritis Quality of Life questionnaire) was developed in the UK and the Netherlands as a disease-specific tool. It was adapted for use in the Australian social context and the reliability and validity was tested. A lay panel assessed the UK version and adapted the wording for use within Australia. Reliability and validity were assessed by a postal survey of the RAQoL and comparator questionnaires to 100 patients with RA. The RAQoL was easily adapted into Australian-English. Test–retest reliability was high with a Spearman rank correlation coefficient of 0.93. RAQoL scores correlated well with patient-perceived disease activity and severity—indicating good validity. The Australian version of the RAQoL is a valid and reliable tool for the assessment of quality of life. It is practical, easy to administer and has good potential for use in clinical settings and trials in Australia.
