Background: Measuring quality of life (QOL) is an important means of assessing the impact of headache. The currently used QOL questionnaires are usually geared toward migraine and focus on a limited number of factors, thus they are not necessarily informative in other headache types. We report the psychometric properties of a new questionnaire, the Comprehensive Headache-related Quality of life Questionnaire (CHQQ) that may be more sensitive to the burden of headache.Patients and methods: A total of 202 patients suffering from migraine (n = 168) or tension-type headache (TTH) (n = 34) completed the CHQQ and SF-36, a generic QOL questionnaire.

Reliability was excellent with Cronbach’s alpha being 0.913 for the whole instrument (0.814–0.832 for its dimensions). The dimensions and total score showed significant correlations with the patients’ headache characte...
