Headache Impact Test (HIT-6)
Posted on July 31 2023,

HIT-6 is a reliable and valid tool for discriminating headache impact across episodic and chronic migraine. It was designed to provide a global measure of adverse headache impact and was developed to use in screening and monitoring patients with headaches in both clinical practice and clinical research.
The four headache impact severity categories are little or no impact (49 or less), some impact (50–55), substantial impact (56–59), and severe impact (60–78).
