Screening for depression among neuro-otology patients with and without identifiable vestibular lesions

Abstract

The experience of depression and anxiety among a sample of 91 patients with complaints of vertigo or dizziness was assessed using a widely available screening instrument, the Hospital Anxiety and Depression Scale (HADS). Questionnaires to assess reported symptoms, self-esteem and social support were also administered. On the basis of clinical vestibular testing, 53% of participants were classified as having a labyrinthine disorder (canal paresis or positional vertigo), 22% as having a vestibular imbalance (spontaneous nystagmus or directional preponderance), and 251% as having no identifiable vestibular abnormality (negative test results). Based on the self-report measures using the screening instrument, 17% of the sample could be classified as depressed, and 29% as anxious. The presence of a vestibular lesion (based on clinical findings) was not associated with reported depression (F (3, 72) = 0.98, p = 0.41). The variables were entered into a hierarchical multiple regression analysis with depression as the dependent variable. A model emerged which accounted for 50% of the variance. Three variables comprised the final model: anxiety (beta = 0.44, p < 0.001), self-esteem (beta = 0.27, p < 0.01), and satisfaction with social support (beta = 0.25, p < 0.01). The results demonstrate the value of identifying psychosocial factors, as well as disease characteristics, among patients presenting at neurootology clinics. In particular, the findings highlight the importance of screening for emotional distress in this patient group, regardless of clinical test results or severity of self-reported symptoms.
