The role of symptoms in the recognition of mental health disorders in primary care.

This study investigates the role of patients' complaints and symptoms in the diagnostic process of mood and anxiety disorders in general practice. In 12 primary care practices, 1,211 patients were diagnosed with the aid of the National Institute of Mental Health Diagnostic Interview Schedule, then the diagnoses were compared with those established by the general practitioners. A low rate of concordance was found between these diagnoses. The absence of somatic illnesses and the presence of psychological complaints were the most important factors in the recognition of a mental illness by the general practitioners. The concordance between the general practitioners and the DIS diagnoses was higher if the patients had neither an acute nor a chronic somatic illness.
