Detailed Description+

The test set CFSD Cognitive Functions - Schizophrenic Disorders assesses the cognitive status of patients with various forms of schizophrenia.

In addition to positive and negative symptoms, impairments of cognitive functions (such as attention and memory) are frequently encountered in schizophrenia. They are associated with significant restrictions of everyday functioning and have a major impact on the social and occupational rehabilitation of the affected person. Schizophrenic disorders usually commence fluidly in adolescence and become chronic. It is therefore particularly important to use this test set with individuals in whom a schizophrenic disorder is suspected and to assess the progress of the disorder. In the context of clinical neuropsychology the CFSD provides an efficient means of assessing adult psychiatric patients.

The specific findings of the studies of the validity of each test in the CFSD test set are quoted in the relevant test manuals. As is documented in the manuals for the individual tests, the tests used are valid tools for measuring the underlying ability dimensions. In addition, the ability dimensions that are tested are of central importance for the neuropsychological assessment of patients with schizophrenic disorders. Multicenter validation studies of the test set with adults with schizophrenia and healthy people are currently being conducted with the SRH Clinic in Langensteinbach, the University of Heidelberg and other partner clinics in Germany and Austria.
