Psychometric properties of the Turkish version of the Vestibular Migraine Patient Assessment Tool and Handicap Inventory

Abstract

Background/aimThere are insufficient tools to assist in the diagnosis and treatment of vestibular migraine. The aim of the study to perform the Turkish adaptation of the Vestibular Migraine Patient Assessment Tool and Handicap Inventory (VM-PATHI).Materials and methodsAfter language and content validity was completed, a pilot study was conducted. Exploratory and confirmatory factor analyzes were conducted to test construct validity, and as a result of validity analyses, Cronbach α internal consistency coefficient and test-retest analyzes were conducted for reliability.ResultsIn the study in which 289 participants were evaluated, the Kaiser-Meyer-Olkin coefficient was calculated as 0.903. The percentage of variance explained by the explanatory factor analysis was 67.246% and the range of factor load change was 0.433-0.828. The scale structure was tested with confirmatory factor analysis and the model was confirmed with adequate goodness of fit index values. Cronbach's α internal consistency coefficient of the scale was 0.931.ConclusionThe VM-PATHI is a valid and reliable tool for the subjective evaluation of vestibular migraine in Türkiye.
