Abstract
Introduction: A subject sleep diary (SSD) capturing 14 sleep parameters was developed to assess daily fluctuations in atopic dermatitis (AD)-associated sleep disturbance. This study aimed to evaluate the psychometric properties of the SSD using data including all randomized patients from the phase 3 ARCADIA 1 (NCT03985943) and ARCADIA 2 (NCT03989349) trials of nemolizumab in adults and adolescents (age ≥ 12 years) with moderate-to-severe AD.
Methods: Reliability, validity, and responsiveness of the SSD were evaluated, and its relationship with the single-item Sleep Disturbance Numerical Rating Scale (SD NRS) was examined using the equipercentile linking method.
Results: In ARCADIA 1 (N = 941), most SSD parameters showed good test-retest reliability (intraclass correlations ≥ 0.70) in patients with stable scores over 1 week on sleep disturbance or itch measures. The SSD parameters of wakefulness after sleep onset (WASO), total awake time (TWT), sleep efficiency (SE), number of times (NWASO-AD) and duration (WASO-AD) of AD-related WASO, and sleep quality/refresh (SQR) showed moderate or strong correlations (r = 0.30-0.66) at baseline, in the expected direction; with the SD NRS and at least one of the measures assessing itch and skin disease-related quality of life (Pruritus Categorical Scale, Peak Pruritus NRS, Average Pruritus NRS, and Dermatology Life Quality Index). Correlations with measures assessing distal concepts were weak for most sleep parameters. Sleep onset latency (SOL), WASO, TWT, SE, NWASO-AD, WASO-AD, and SQR demonstrated good known-groups validity at baseline and week 16, and showed responsiveness based on most anchors used in the analysis. Values of the same percentile rankings for the SD NRS and each SSD parameter were identified. Comparable results were obtained using ARCADIA 2 data (N = 787).
Conclusions: The results provided evidence that the SSD, particularly its SOL, WASO, TWASO, TWT, SE, NWASO-AD, WASO-AD, and SQR parameters, is reliable and valid to measure multidimensional concepts of sleep disturbance in clinical studies.
期刊介绍：
Dermatology and Therapy is an international, open access, peer-reviewed, rapid publication journal (peer review in 2 weeks, published 3–4 weeks from acceptance). The journal is dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of dermatological therapies. Studies relating to diagnosis, pharmacoeconomics, public health and epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to all clinical aspects of dermatology, such as skin pharmacology; skin development and aging; prevention, diagnosis, and management of skin disorders and melanomas; research into dermal structures and pathology; and all areas of aesthetic dermatology, including skin maintenance, dermatological surgery, and lasers.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols, and short communications. Dermatology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an International and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. The journal appeals to a global audience and receives submissions from all over the world.
