Validity of Headache Disability Index

The aim of our study is to investigate the Turkish validity and reliability of The Henry Ford Hospital Headache Disability Questionnaire (HDI), which has not been previously studied in a Turkish version for any headache type in patients with cervicogenic headache.

Headache is a health problem that is reported to occur in 66% of the global population, reducing both quality of life and work productivity. The most common type is tension headache with a prevalence of 38%, followed by migraine headaches with 10%. The incidence of cervicogenic ligament pain has been shown to be between 2.5 and 4.1%. It has been reported that although the prevalence of cervicogenic headache is low compared to tension-type headache and migraine, it affects the quality of life in patients similarly.he International Headache Society has defined cervicogenic headache as pain felt in at least one area of the face or head that radiates from a source in the neck. The most common clinical picture of cervicogenic headache is neck pain, which is usually unilateral and may radiate from the occipital region to the orbit. It has been suggested that neck pain and headache are common comorbidities. Cote et al. reported that headache complaint is 10 times more common in people with neck pain than in people without neck pain.It has been reported that an average of 60-80% of individuals suffering from chronic neck pain have headache problems. C.The validity and reliability studies of the questionnaire on headache in Turkey were generally conducted in patients with migraine. Dikmen et al. performed the Turkish validity and reliability study of the Headache Impact Test-6 (Headache Impact Test-6) questionnaire in patients with migraine. Ertaş et al. published the Turkish version of the Migraine Disability (MIDAS) Questionnaire in the same patient group. However, we could not find a Turkish validity and reliability study of a questionnaire in patients with cervicogenic headache in our country.

The Henry Ford Hospital Headache Disability Questionnaire (HDI), developed by Jacobson et al. in 1994, is a 25-item questionnaire that examines the effects of headache on daily life. This questionnaire has a two-factor structure emotionally and functionally. Scoring (No: 0, Sometimes:2, Yes:4) varies between 0 and 100. The higher the score, the more headache disability.
