Obsessive compulsive disorder--prevalence in Xhosa-speaking schizophrenia patients.
Obsessive compulsive disorder (OCD) has been reported in up to 31% of schizophrenia sufferers. This study evaluated the presence of OCD in a Xhosa-speaking schizophrenia group. Xhosa patients (N = 509, including 100 sibships) with schizophrenia were recruited from hospital and community settings. The patients underwent a structured clinical interview for the presence of lifetime co-morbid schizophrenia and OCD. Only 3 patients (0.5%) fulfilled criteria for OCD. No concordance for OCD was noted in the sibship group. Our findings differ from those in other parts of the world, and if replicated, might suggest unique protective environmental or genetic factors for OCD in certain ethnic groups.
