A group of outpatients scheduled for hearing evaluation were screened for psychiatric morbidity using the General Health Questionnaire (GHQ-30). There was an association between objective hearing loss and elevated GHQ-30 score. An association was also found between the presence of tinnitus and vestibular symptoms and elevated GHQ-30 score.
