This is an observational, cross-sectional study addressing the factors influencing treatment decisions in patients with PsA. Participants will be treated as usual in their routine clinical practice, but decisions on treatment will be recorded - whether treatment is escalated, unchanged or reduced, and why.
The study will be conducted in 25 rheumatology centres in Europe (UK, France, Germany, Spain and Italy) with five centres in each country. Each participant will only attend for one single study visit which is likely to last around 30 minutes in total. This will be alongside the participant's routine clinic visit. The PsAID-12 questionnaire will be implemented on a tablet computer but the remaining outcomes will be collected on paper CRFs and transferred to a database for analysis.
