Science of assessment.
Psoriatic arthritis is a multisystem disorder which, from a measurement standpoint, demands consideration of its cutaneous manifestations and both axial and peripheral musculoskeletal involvement. Measurements of various aspects of impairment, ability/disability, and participation/handicap are feasible using existing measurement techniques, which are for the most part valid, reliable, and responsive. Nevertheless, there remain opportunities for the further development of consensus around core set measures and responder criteria, as well as for instrument development and refinement, standardised assessor training, cross-cultural adaptation of health status questionnaires, electronic data capture, and the introduction of standardised quantitative measurement into routine clinical care.
