摘要

Background and Aims

The Pediatric Vestibular Symptom Questionnaire (PVSQ) identifies vestibular disorders in children. We developed the Persian version (PVSQ-P) and evaluated its psychometric properties to help children communicate symptoms and assist therapists in diagnosis.

Materials and Methods

The study involved 168 typically developing children and 35 children with vertigo, imbalance, and dizziness aged 6 to 17. The PVSQ-P was adopted following the IQOLA protocol. We evaluated face, content, construct validity, internal consistency, and test-retest reliability. We obtained the questionnaire’s cutoff point with sensitivity and specificity. Discriminant validity was assessed by comparing scores between case/control groups and among vestibular etiologies.

Results

The psychometric analyses confirmed that the PVSQ-P is reliable and valid, with a Cronbach’s alpha of 0.869 and an Intraclass Correlation Coefficient of 0.843, indicating strong internal consistency. Confirmatory factor analysis validated its two-factor structure. The ROC curve identified a cutoff point of 0.95, with 94% sensitivity and 74% specificity. Mean scores significantly differed between normal children (0.63 ± 0.63) and those with vestibular symptoms (1.82 ± 0.53) (P < 0.001). However, the PVSQ-P could not distinguish peripheral and central vestibular etiologies.

Conclusions

The PVSQ-P is useful for identifying children with vestibular disorders.
