The Calgary Depression Scale for Schizophrenia has been developed by Drs. D. and J. Addington at the University of Calgary. The Scale was specifically developed to assess the level of depression in schizophrenia. It has been extensively evaluated in both relapsed and remitted patients and appears sensitive to change. 

The Scale is currently available in 40 languages: Arabic, Bulgarian, Cantonese, Croatian, Czech, Danish, Dutch, Farsi, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian Bahasa, Italian, Japanese, Korean, Latvian, Malay, Mandarin (Simplified), Mandarin (Traditional), Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Spanish (Argentina), Spanish (Mexico), Spanish (Spain), Swedish, Tagalog, Thai, Turkish, Ukrainian and Yoruba. 

 It is important to note that the Scale is designed for use by an experienced rater. It is not intended for self assessment, and any person concerned about schizophrenia should see a medical professional. The University of Calgary, Alberta Health Services and Drs. D. and J. Addington accept no responsibility for the Scale if it is not administered under appropriate conditions by a professional.
