Minimal clinically important difference (MCID) for work productivity and activity impairment (WPAI) questionnaire in psoriasis patients

Abstract

The clinical meaningfulness of improvements in the Work Productivity and Activity Impairment Questionnaire for Psoriasis (WPAI‐PsO) reported by patients with psoriasis in response to treatment is unknown due to the lack of any publications that report minimal clinically importance differences (MCID) for WPAI‐PsO outcomes.
