Background: The dizziness symptom profile (DSP) is a case history-based questionnaire that can differentially diagnose patient with vertigo into vestibular disorder at a preliminary level. Aim of the Study The current study explored and compared response patterns on different questions/statements of DSP questionnaire after adapting it into the Indian Language Marathi for different vestibular disorders. Methods: A prospective exploratory study was conducted on a clinical population having vertigo or dizziness due to different vestibular disorders. A total of 60 patients with primary complaints of dizziness filled the Dizziness Symptom Profile - Marathi (DSP-M) questionnair which was adpated into Indian Marathi language from its original English version (DSP-E). Test–retest reliability and internal consistency of the item were assessed for the adapted questionnaire and different symptom patterns were analyzed for patients with four peripheral vestibular disorders. Results: DSP-M was found to have good test–retest reliability with intraclass correlation value of 0.683. Internal consistency for all the questions was found to be strong with a Cronbach alpha value of α = 0.92. DSP-M depicted a similar symptoms response pattern as described by the original author of the questionnaire nevertheless few variations were also found for patients with vestibular neuritis and vestibular migraine. Conclusions: DSP-M can be used for preliminary diagnosis of patients with these abovementioned vestibular disorders.
