Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This is a survey to understand sleep in the context of medical trainees (on call) and the participants knowledge about the relevance of sleep, shiftwork, and the impact that sleep may have on their working performance. The survey has been developed by sleep experts from America, Europe, and Africa, in collaboration with the World Sleep Society. It should take about 30-40 minutes to complete.
The survey will focus on three different aspects, complemented by two standard questionnaires:
1. Demographics and Place of Work
2. Basic Knowledge and Perception of Sleep
3. Sleep Routine
4. Epworth Sleepiness Scale, Insomnia Sleep Inventory
