title: [Formulation and evaluation of diagnostic questionnaire for benign paroxysmal positional vertigo].
abstract: Objective:To formulate and evaluate a rapid assessment questionnaire for benign paroxysmal positional vertigo(BPPV).Methods:The rapid assessment questionnaire for benign paroxysmal positional vertigo was developed based on the core clinical manifestations of BPPV.A total of 235 dizzy patients, with an average age of 56±16, were recruited from the Navy General Hospital during October 2015 to March 2016.The assessments were made by two specialists for BPPV, and the diagnoses were confirmed through follow-up.The reliability and validity of the scale questionnaire were analyzed with the SPSS 19.0 and the cutoff point was confirmed with the Receiver operating characteristic(ROC) curve analysis.Results:Reliability test: Cronbach α value for the questionnaire was 0.644; Validity: KMO (Kasier-Meyer-Olkin) value for the questionnaire was 0.711.Two factors were used with a characteristic root of higher than 0.9.The total cumulative contribution rate was 53.816%.The load of each item was over 0.5.The range of the scale is 0 to 6 points, with the largest ROC curve area (0.894) at 3 points for the diagnosis of BPPV.The relative sensitivity and specialty were 92.45% and 71.60% , respectively.Conclusions:This rapid assessment questionnaire for benign paroxysmal positional vertigo posses good reliability and validity, and can be used as a tool for a quick diagnosis of BPPV for patients with dizziness. BPPV can be diagnosed with a score of 3 by using this questionnaire.
