Scale construction of the Swedish CPRS version

A sample of 161 schizophrenic and depressive patients were interviewed in a Stockholm hospital to find out whether the Comprehensive Psychopathological Rating Scale construction carried out by Maurer et al. [Int. Pharmacopsychiat. 17: 338-353, 1982] and valid for German-speaking areas could be reproduced with a Swedish-speaking sample. Only the superimposed 2-factor solution resembled, in its factor-structure, that of Maurer et al. (depressive and schizophrenic syndrome). The fact that a 'depressive' syndrome was found instead of a 'manic-depressive' syndrome, is to be attributed to the different sample compositions.
