Psychometric validation and responder definition of the sleep disturbance numerical rating scale in moderate-to-severe atopic dermatitis.

ABSTRACT:

Background

Sleep disturbance (SD) is an important part of the burden of atopic dermatitis (AD), but patient-reported outcomes that are easy to understand and interpret in the target population have been lacking. A daily, single-item, self-reported SD 11-point numerical rating scale (NRS) was recently developed to assess SD for patients with moderate-to-severe AD, but its psychometric properties have not yet been described.

Objectives

To assess the psychometric properties of the SD NRS in patients with moderate-to-severe AD.

Methods

The psychometric properties of the SD NRS were assessed using data from a phase IIb clinical trial in 218 adults with moderate-to-severe AD.

Results

Test-retest reliability of the SD NRS was substantial to almost perfect (interclass
