Detailed Description+

The test set CFSD – Cognitive Functions Schizophrenic Disorders assesses the cognitive status of individuals 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 significantly restrict everyday functioning and have a severe impact on patients’ social and occupational rehabilitation. Schizophrenic disorders often 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.

Validation+

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.
