The Calgary Depression Scale for Schizophrenia (CDSS)

The Scale

The Calgary Depression Scale for Schizophrenia (CDSS) is a nine item clinician rated outcome measure that assesses the level of depression in people with schizophrenia. It is the only depression scale designed to assess depression in people with a schizophrenia spectrum disorder including the attenuated psychosis syndrome. It distinguishes depressive symptoms from negative positive and extrapyramidal symptoms. The scale works in both relapsed and remitted patients and is sensitive to change. It is valid in adolescents and adults. Reviewers describe it as the gold standard measure for assessing depression in schizophrenia.
