BACKGROUND The Migraine Disability Assessment (MIDAS) instrument is a five-item questionnaire developed to measure headache-related disability and improve doctor-patient communication about the functional consequences of migraine. OBJECTIVES To examine the test-retest reliability and internal consistency of the five items and of the overall MIDAS score in(More)
The MIDAS Questionnaire was developed to assess headache-related disability with the aim of improving migraine care. Headache sufferers answer five questions, scoring the number of days, in the past 3 months, of activity limitations due to migraine. The internal consistency, test-retest reliability, and validity (accuracy) of the questionnaire were assessed(More)
The Migraine Disability Assessment (MIDAS) questionnaire is a brief, self-administered questionnaire designed to quantify headache-related disability over a 3 month period. The MIDAS score has been shown to have moderately high test-retest reliability in headache sufferers and is correlated with clinical judgment regarding the need for medical care. The aim(More)
BACKGROUND The Migraine Disability Assessment (MIDAS) score is used to quantify headache-related disability. In a previous study, we showed that the MIDAS score was highly reliable in population-based samples of migraine headache sufferers in two countries. OBJECTIVES To examine the test-retest reliability and internal consistency of the five items(More)
BACKGROUND Migraine is three times more common in women than men. There is a clinical impression that migraines are more common and severe around the time of menses. OBJECTIVES To determine 1) the distribution of headache attacks by day of the menstrual cycle in women with migraine, 2) if the excess occurrence varies by headache type, and 3) if headache(More)
CONTEXT Various guidelines recommend different strategies for selecting and sequencing acute treatments for migraine. In step care, treatment is escalated after first-line medications fail. In stratified care, initial treatment is based on measurement of the severity of illness or other factors. These strategies for migraine have not been rigorously(More)
OBJECTIVE We evaluated the agreement between Migraine Disability Assessment (MIDAS) scores and independent physician judgments about pain, disability, and treatment needs based on patient medical histories. BACKGROUND The MIDAS questionnaire measures headache-related disability as lost time due to headache from paid work or school, household work, and(More)
OBJECTIVE To examine the cost effectivess of a stratified-care regimen for patients with migraine--in which patients are stratified by severity of illness, and then prescribed differing treatments according to level of severity--compared with a conventional stepped-care approach. DESIGN AND METHODS A decision analytic model was constructed to simulate a(More)
OBJECTIVE To assess physician-patient communication about headache-related disability and to evaluate the influence of information about disability on physicians' perceptions of illness severity and the treatment needs of migraineurs. BACKGROUND Evidence suggests that migraine is suboptimally treated in clinical practice, partly due to poor communication(More)
