Determining Severity Strata for Three Atopic Dermatitis Patient-Reported Outcome Questionnaires: Defining Severity Score Ranges for the Worst Pruritus Numerical Rating Scale and the Atopic Dermatitis Symptom and Impact Scales (ADerm-SS and ADerm-IS).

Three patient-reported outcome (PRO) questionnaires-Worst Pruritus Numerical Rating Scale (WP-NRS), Atopic Dermatitis Symptom Scale (ADerm-SS), and Atopic Dermatitis Impact Scale (ADerm-IS)-were developed to assess the symptoms and impacts of atopic dermatitis (AD). Severity strata for these PROs are needed to aid in their interpretation.
