The Scale

The Calgary Depression Scale for Schizophrenia (CDSS) was developed to assess the level of depression in schizophrenia.  It is the only depression scale designed for the assessment of depression in schizophrenia and it differentiates between depression and the negative and positive symptoms of schizophrenia.  It has been extensively evaluated in both relapsed and remitted patients and is sensitive to change.  You can review the studies on the CDSS on PubMed (PubMed link here).  It has been cited in over 1,300 publications according to the Web of Science Citation Index.
