Abstract

The Vertigo Symptom Scale (VSS) was designed to assess and differentiate symptoms of: (a) balance disorder; and (b) somatic anxiety and autonomic arousal in patients complaining of dizziness and vertigo. Although it has been translated for use in countries other than the UK, where it was originally developed, its validity in different languages and cultures has not previously been evaluated. This study examined the structure, reliability, and discriminative power of a Spanish translation of the VSS administered to a Mexican sample of 172 dizzy patients and 40 healthy controls. Scores on the two subscales of the VSS not only discriminated between patients and controls, but were also sensitive to differences between patient groups classified on the basis of diagnosis, test results, and occupational disability. The pattern of intercorrelations between symptoms, anxiety, depression, and handicap in the Mexican sample was almost identical to that observed in the original UK sample.
