Somatic symptom distress and gender moderate the effect of integrative group psychotherapy for functional vertigo on vertigo handicap: A moderation analysis of a randomised controlled trial

A possible explanation for this result is that somatic symptom distress is the central aetiopathogenetic factor of functional vertigo, while depressiveness and anxiety are rather epiphenomena in the sense of comorbidity. Although the results are not entirely consistent, according to some studies, female gender seems to be a favourable predictor of better therapy outcome. Given the high impairment and healthcare costs in those with vertigo/dizziness and psychiatric comorbidity, it is important to effectively treat these patients as early as possible. This study provides a prescriptive tool for practitioners, allowing for more patient-tailored treatment decisions.
