Validation of the Comprehensive Online Sleep Monitoring Scale (COSMOS) in a Large Population Sample.

The article discusses the development and validation of the Comprehensive Online Sleep Monitoring Scale (COSMOS) for self-reported sleep assessment in a large population sample of 5,815 adults. The scale showed good internal and convergent validity, with associations to established sleep scales, and demonstrated construct validity by identifying poorer sleep scores in participants with psychological conditions and higher levels of depression, anxiety, compulsivity, and neuroticism traits. The researchers propose COSMOS as a comprehensive tool for large-scale online transdiagnostic and mental health research. [Extracted from the article]
