What is OASIS?
OASIS (Overall Anxiety Severity and Impairment Scale) is a 5-item test used to measure the severity and impairment associated with anxiety disorders.

The test is not a diagnostic tool and its result does not constitute a diagnosis of a mental disorder.

If you suspect that you have an anxiety disorder and want to obtain a reliable diagnosis, contact a mental health specialist

The online test is intended only for people over 18 years of age.

The questions below are about anxiety and fear. These symptoms may include panic attacks, situational anxiety, worry, flashbacks, hypervigilance or startle. When answering these questions, include all of your anxiety symptoms. For each item, circle the number in the answer that best describes your experience over the past week.
