PMID 38055412WHAT IT FOUND
The Brazilian Portuguese version of the CIEV questionnaire reliably identifies emotional impact and anxiety risk in patients with vertigo.
It correlates strongly with the Dizziness Handicap Inventory, particularly in the emotional domain, offering a practical tool for assessing psychological distress in vestibular patients.
Key findings
01The CIEV showed high internal consistency (alpha 0.858) and moderate reliability (ICC 0.695) when compared to the Dizziness Handicap Inventory total score.
02Correlations between the CIEV and the DHI were strongest in the emotional domain (ICC 0.869), reflecting the CIEV's specificity for anxiety-related symptoms.
03In the sample of 38 patients, 78.95% were classified as being at risk for pathological anxiety by the CIEV, and most of these also showed moderate-to-high handicap on the DHI.

What it does not show
The sample size was small (38 participants), which limits the generalizability of the psychometric properties. The version of the CIEV used was a free translation by the original authors and lacked formal linguistic and cultural adaptation for Brazil. The sample was heterogeneous regarding the type of dizziness and comorbidities, and variables like medication use were not controlled. The study excluded patients with prior psychiatric diagnoses, so the results do not apply to patients with known mental health conditions.

The easy way to misread this
Do not interpret the high correlation with the DHI as proof that the CIEV diagnoses anxiety disorders. It is a screening tool for emotional impact and risk, and the lack of formal cultural adaptation means it should be used with caution until further validation is completed.
