Validation of the Vitiligo Noticeability Scale: a patient-reported outcome measure of vitiligo treatment success.

ABSTRACT:

Background

Patient-reported outcome measures are rarely used in vitiligo trials. The Vitiligo Noticeability Scale (VNS) is a new patient-reported outcome measure assessing how 'noticeable' vitiligo patches are after treatment. The noticeability of vitiligo after treatment is an important indicator of treatment success from the patient's perspective.

Objectives

To evaluate the construct validity, acceptability and interpretability of the VNS.

Methods

Clinicians (n = 33) and patients with vitiligo (n = 101) examined 39 image pairs, each depicting a vitiligo lesion pre- and post-treatment. Using an online questionnaire, respondents gave a global assessment of treatment success and a VNS score for treatment response. Clinicians also estimated percentage repigmentation of
