The Psoriasis Area and Severity Index (PASI) and Physician Global Assessment (PGA) are commonly used, but fail to measure quality of life and the patient's perception of well-being. In response to these limitations, the National Psoriasis Foundation (NPF) Medical Advisory Board has developed the NPF Psoriasis Score (NPF-PS). This article evaluates the degree of concordance between NPF-PS, PASI, and PGA scores via an investigator-initiated, single-center, double-blind, placebo-controlled study of thirty-three patients with moderate to severe plaque psoriasis. Our results indicated that NPF-PS was strongly correlated with PASI and PGA in this study, while better reflecting patient perception. This is the first report of a double-blind placebo-controlled study demonstrating this concordance.
