AI Insight
Researchers developed and validated the Comprehensive Online Sleep Monitoring Scale (COSMOS), a self-reported questionnaire designed specifically for unsupervised online administration. Testing on 5,815 adults demonstrated strong internal consistency, good correlation with established sleep assessment tools, and the ability to detect sleep disturbances associated with mental health conditions including depression, anxiety, compulsivity, and neuroticism. The scale addresses limitations of traditional sleep assessment instruments that were originally designed for supervised, in-person administration.
Why it matters
This validated online tool enables large-scale sleep research and mental health studies to be conducted remotely with greater accessibility and lower costs. The scale's optimization for independent online use makes it particularly valuable for population-level research and could facilitate broader screening for sleep problems linked to mental health conditions.
Understand the Science
Researchers are increasingly studying cognitive and psychological constructs using automated online tools due to advantages in scalability, repeatability, accessibility and affordability. The online assessment of sleep presents a challenge, as the most popular instruments for reporting different aspects of sleep were originally designed to be deployed under supervised conditions by trained personnel. Here, we develop and validate the Comprehensive Online Sleep Monitoring Scale (COSMOS), a self-reported sleep scale optimised for online, independent administration. Using data from N = 5,815 adults, we show that COSMOS has good internal (Cronbach’s α = 0.85) and convergent validity, via strong associations with established sleep scales. Poorer COSMOS sleep scores were found in participants diagnosed with mental health conditions, more frequent depression or anxiety symptoms, and higher compulsivity or neuroticism traits, demonstrating good construct validity. We propose COSMOS as a comprehensive and validated sleep assessment that is suitable for large-scale online transdiagnostic and mental health research.
