We have tested Turkish version of the Migraine Disability Assessment (MIDAS) questionnaire in patients with tension type headache. Thirty-two patients who had a tension type headache were included. Turkish version of the MIDAS questionnaire was applied to all patients. Additionally, the patients were asked to keep a 90-day diary. The day diary and the MIDAS questionnaire were compared at the end of the study period. We found that cronbach's alpha 0.82 and had good reliability. Our findings suggest that the MIDAS questionnaire that was originally designed for patients with migraine may be used in patients with chronic tension type headache.
