COMPARISON OF CLINICIAN RATED AND FAMILY CORROBORATIVE WITNESS DATA FOR DEPRESSED-PATIENTS

There appear to be few published studies that have examined the levels of agreement between ratings of features of depression as assessed by clinicians and by corroborative witnesses. We therefore report a study of 141 depressed patients assessed by a clinical psychiatrist at a semi-structured interview, reviewing family and historical data as well as depressive symptoms, and rated on a series of designated mental state signs. A family member completed questionnaire data assessing the same features. Moderate agreement was obtained only for several historical items (e.g., previous depressive episode, response to ECT). Agreement was minimal or non-existent on numerous clinical symptoms and signs of depression. A number of sources of disagreement are considered, and it is suggested that discordance may have emerged principally from the contrasting domains and training experiences of the clinicians and the corroborative witnesses.
