Test basis

Format: ISI. Answer based on your current state rather than trying to choose a "right" result.

Sleep problems can be related to stress, anxiety, medical issues, or routines; this test is not a diagnosis. If you feel unsafe, at risk of harming yourself, or in severe distress, contact local emergency services or a qualified professional.
