Background: Pruritus, skin pain, and sleep disturbance are a significant burden to individuals with moderate-to-severe atopic dermatitis (AD) and negatively impact quality of life. Fit-for-purpose patient-reported outcome measures (PROMs) that assess AD-related pruritus, skin pain, and sleep disturbance are important for evaluating the effectiveness of new AD treatments.

Objectives: To evaluate content validity of five AD-related PROMs in adolescents and adults with moderate-to-severe AD (the Worst Pruritus Numeric Rating Scale [NRS], the AD Skin Pain NRS; the Sleep Disturbance NRS, the skin pain-specific Patient Global Impression of Change [PGIC], and the skin pain-specific Patient Global Impression of Severity [PGIS]) and to assess patient-reported experience with pruritus, skin pain, and sleep disturbance.
