The Rorschach method: The development from early systems for analysis and interpretation to Exner's Comprehensive System

In clinical work the Rorschach has always been regarded as a useful method. However, its reliability and validity have been uncertain, and the value of the test as a research instrument has often been questioned. In this paper the development of the test is reviewed, and the "Comprehensive System" developed by Exner and co-workers is presented. This system provides an empirically founded combination of previous Rorschach systems with a conceptual basis that cuts through different theoretic perspectives. In the USA the Comprehensive System has become the most frequently used system for analysing Rorschach data, and a similar development can be anticipated also in Scandinavia.
