Abstract
- The aim of this paper was to assess the validity and reliability of the touch-screen standard Portuguese version of the following patient-reported outcomes (PROs), compared with paper format, in patients with rheumatoid arthritis (RA) and spondyloarthritis: Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Ankylosing Spondylitis Quality of Life scale (ASQoL), Short-Form 36 (SF-36), Health Assessment Questionnaire (HAQ) and visual analogue scales (VAS) measuring pain and burden of disease. Adult patients with RA and spondyloarthritis attending the Portuguese Institute of Rheumatology were recruited from March 2013 to January 2014. Patients filled the paper and touch-screen formats of the standard Portuguese versions of the PROs. Two groups of VAS were used, RA and psoriatic arthritis (Global VAS) and another specific for spondyloarthrites (Spa-VAS). Paper questionnaires were filled 15 min before touch-screen formats. Agreement between formats (validity) was assessed by intraclass correlation coefficient (ICC), while internal consistency of scales (reliability) was assessed by Cronbach's alpha. Overall, 134 patients were included with a mean age of 51 years, 74.6 % female and 57.5 % presenting RA. BASDAI, BASFI, HAQ and ASQoL showed high ICC between paper and touch-screen formats (0.977, 0.958, 0.974 and 0.940, respectively). ICC for Global VAS ranged from 0.906 to 0.921, while Spa-VAS ranged from 0.867 to 0.943. The mean ICC for all SF-36 domains was 0.889 (ICC for each domain ranged from 0.781 to 0.944). Touch-screen standard Portuguese formats of these PROs may be valid and reliable tools for PRO measurement in rheumatology.
