Overview
The purpose of this study is to assess the impact of adding two questions and pictures to the validated PEST on the potential diagnosis of PsA in participants with moderate-to-severe plaque PsO in Canada.
Description
Patients will be enrolled in the study for up to 66 days and will be asked to fill-out a PsA screening questionnaire at their first dermatologist visit. Patients screening positive for PsA will have a second visit with a rheumatologist where a full PsA diagnosis assessment will be performed. A remote 'end of study' (EOS) visit will be conducted by the dermatologist to document the patient's biologic Disease-Modifying Antirheumatic Drugs (bDMARDs) treatment choice and status.

Key exclusion criteria:
