This sleep-quality questionnaire—the Sleep Condition Indicator—was developed by Colin Espie, professor of sleep medicine at the University of Oxford and a cofounder of the sleep-education app Sleepio. Consider it a helpful, sciencebacked tool to start a conversation with yourself, your family, and your friends, and a useful reference as you take steps to renew or sustain your relationship with sleep.

To start, circle the most accurate response for each question. At the end, add up your points to get your sleep assessment, along with tips for improvement.
