ABSTRACT
OBJECTIVE:
The aim of this article is to develop and validate a disease-specific, patient-reported outcome measure for vestibular migraine.SETTING:
Tertiary care vestibular center. PATIENTS Adult patients with definite or probable vestibular migraine per Barany Society Criteria. STUDYDESIGN:
This was a prospective cohort study. VM-PATHI (Vestibular Migraine Patient Assessment Tool and Handicap Inventory) was developed with expert input, literature review, and patient feedback. VM-PATHI scores were compared between those with vestibular migraine and controls, across several time points, and to other dizziness and quality of life (QoL) measures.RESULTS:
A 25-item questionnaire was developed. Cronbach's α was high at 0.92. Test-retest reliability was excellent (râ=â0.90, pâ<â0.001). Scores were much higher in patients with vestibular migraine (mean 42.5, SDâ=â16.1) than control patients (meanâ=â9.6, SDâ=â8.5). VM-PATHI scores were responsive to treatment (pâ=â0.01). Scores were well correlated with general QoL, depression, and anxiety scores. Scores were also correlated with the Dizziness Handicap Inventory (râ=â0.69). An exploratory factor analysis was performed, which revealed 6 distinct factors that corresponded well to different aspects of disease-related symptomatology.CONCLUSION:
VM-PATHI is a valid, reliable, and responsive measure of disease severity in vestibular migraine.
