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

Background/aim: There are insufficient tools to assist in the diagnosis and treatment of vestibular migraine. Hence, the aim of this study was to perform the Turkish adaptation of the Vestibular Migraine Patient Assessment Tool and Handicap Inventory (VM-PATHI).

Materials And Methods: After the language and content validity was completed, a pilot study was conducted. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to test construct validity, and as a result of the validity analyses, Cronbach's alpha internal consistency coefficient and test-retest analyses were conducted for reliability.

Results: In 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 EFA was 67.246% and the range of factor load change was 0.433-0.828. The scale structure was tested with CFA and the model was confirmed with adequate goodness of fit index values. The Cronbach's alpha internal consistency coefficient of the scale was 0.931.

Conclusion: The VM-PATHI is a valid and reliable tool for the subjective evaluation of vestibular migraine in Türkiye.
