Validation of Patient-Reported Outcomes Information System Sleep Disturbance and Sleep-Related Impairment in adults with atopic dermatitis
British Journal of Dermatology
© 2020 British Association of Dermatologists Background: Sleep disturbances are common in adults with atopic dermatitis (AD). Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance (SD) and Sleep-Related Impairment (SRI) are validated questionnaires to assess sleep in adults. Little is known about their measurement properties in adults with AD. Objectives: To assess the measurement properties of the PROMIS SD and SRI eight-item short forms in AD. Methods: We performed a prospective dermatology-practice-based study using questionnaires and evaluation by a dermatologist (n = 420). Results: PROMIS SD and SRI showed moderate correlations to each other (ρ = 0·67), and weak correlations with Patient-Oriented Eczema Measure (ρ = 0·43 and 0·39, respectively); average (ρ = 0·31/0·30) and worst numerical rating scale for itch (ρ = 0·32/0·30); Eczema Area and Severity Index (ρ = 0·41/0·31); and Scoring Atopic Dermatitis (SCORAD) (ρ = 0·44/0·30) (Spearman correlations, P < 0·001). PROMIS SD and SRI increased significantly and stepwise with more frequent sleep disturbance, severe itch and self-reported global AD severity (ancova, P < 0·001). PROMIS SD and SRI showed good internal consistency (Cronbach alpha 0·84 and 0·91). Changes from baseline in PROMIS SD and SRI were weakly to moderately correlated with each other and with changes of multiple patient-reported and clinician-reported AD outcomes. There were no floor or ceiling effects for PROMIS SD or SRI. The median completion time for PROMIS SD and SRI was 2 min. Conclusions: PROMIS SD and SRI showed good construct validity, internal consistency, responsiveness and feasibility to assess sleep in adult patients with AD.
