Depression and Anxiety in Multisomatoform Disorder: Prevalence and Clinical Predictors in Primary Care (Original Articles)
Objective. Multisomatoform disorder (MSD) is characterised by [greater than or equal to] 3 medically inexplicable, troublesome physical symptoms, together with a [greater than or equal to] 2-year history of somatisation. The aim of this study was to evaluate the prevalence of depressive and anxiety disorders in a South African sample MSD, and to compare demographic and clinical outcomes in those patients with and without co-morbidity. Methods. Fifty-one adult outpatients with MSD were recruited from primary care clinics in the Cape Town metropole. Participants were assessed for the presence of co-morbid depressive and anxiety disorders using the Mini Neuropsychiatric Interview-Plus (MINI-Plus). Outcomes included somatic symptom severity, disability, reported sick days and health care visits, pain experience, patient satisfaction with health services, and clinician-experienced difficulty. Results. A current co-morbid depressive disorder was present in 29.4% (N=15) of patients, and a current co-morbid anxiety disorder in 52.9% (N=27). MSD patients with a co-morbid depressive disorder (current or lifetime) had significantly higher physical symptom counts, greater functional impairment, higher unemployment rates, more clinician-reported difficulties, and more dissatisfaction with health care services than those without the disorder. A larger number of co-morbid disorders was associated with greater overall disability.
