title: Development of a new shortened version of Raven's matrices test for application and rough assessment of present intellectual capacity within psychopathological investigation.
abstract: Based on a sample of 300 psychiatric patients the items of the Standard Progressive Matrices test are analyzed in terms of classical and probabilistic methods, and a version shortened to 30 items is developed. This new version of the test is then standardized from a new sample of 1,200 patients. A table of selected percentiles is computed. Validation with respect to rough classification of intelligence is proved by comparison with results of the WIP .
