The BPPV-SQ: Development and Clinical Evaluation of a Brief Screening Questionnaire for Benign Paroxysmal Positional Vertigo

Year: 2026

Type: article

Abstract: Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo and is diagnosed clinically, yet many patients initially present in primary care. Early identification may optimize referral and management. Objective: To perform a pilot Phase 1 validation of the Benign Paroxysmal Positional Vertigo Screening Questionnaire (BPPV-SQ), a brief screening questionnaire designed for future use in general practice (primary care settings where patients are initially evaluated by general practitioners), assessing its ability to identify BPPV, suggest canal involvement, and support progression to Phase 2 validation. Methods: In this prospective observational study, 108 patients with positional vertigo and no neurological signs were evaluated in a specialist setting. The 7-item dichotomous questionnaire (score 0–3 for diagnostic core) was administered prior to bedside examination, which served as the reference standard. Results: Higher questionnaire scores were associated with an increased probability of confirmed BPPV. Among patients with the maximum score of 3, BPPV was confirmed in 73.5% of cases, with a lateralization concordance of 69.4% between questionnaire responses and specialist diagnosis. In contrast, lower scores (0–1) were associated with a markedly lower rate of confirmed BPPV (14.3%). Conclusions: In this pilot Phase 1 validation, the BPPV-SQ demonstrated score-dependent diagnostic reliability and acceptable lateralization agreement in high-score patients, supporting progression to Phase 2 validation in primary care.
