The HIT-6 questionnaire, a short version of Quality Metric's Internet DynHa HIT test using the old-fashioned technology of paper, proved a big hit at the World Congress of Neurology in London, UK, in June. It has been validated against DynHa HIT for the diagnosis of migraine and for evaluating headache severity, and it produces results which compare well. Furthermore, within a population of headache sufferers, it has been shown to effectively predict loss of work productivity due to migraine and headache.
