Rorschach Today

The Rorschach is not dependent on self-report and it does not require any reading and writing. It is instead an information-processing, problem solving task in which the respondent is presented with ink blots and asked what they look like. The Rorschach is particularly good at capturing information about a person as an individual. The intentionally ambiguous nature of the inkblots means that each person’s response to them is unique, and rich in descriptive data.  At the same time, standardisation enables psychologists to compare each individual with a normative sample to make accurate predictions about personality functioning.

The Rorschach is a widely used test internationally. The scoring and interpretation procedures are founded upon a large amount of normative data. The original norms were based on data from North America, and international normative studies have been conducted in sixteen different countries including Australia, Asia, Europe, the Middle East and North and South America. These studies involved nearly nine thousand participants. The participants were all non-patients and results were collated to form the International Reference Sample (Meyer, Erdberg & Shaffer, 2007). Members of the British Rorschach Society are in the process of gathering normative data in England, due to be completed in 2017

The Comprehensive system is based in empirical, psychometric research (for example, see Acklin, 1999). Responses are scored and the scores are combined into indices which can be compared to a normative sample. The way in which the respondent organises his or her responses provides a picture of how perceptions, thoughts and feelings are structured and processed. It is a complex, organic system, where the different personality variables inter-relate in ways that reflect our understanding of personality functioning. This also means that teaching the test and learning to use it properly are labour-intensive endeavours.

Although it is not psychoanalytic per se, the findings that the Comprehensive system yields can be integrated with this approach, as Gacono and Meloy (1994) did in their classic text on assessing antisocial and psychopathic individuals with the Rorschach.

There are interpretative approaches to the Rorschach which are explicitly psychoanalytic (for example, Lerner 1991), but the main system that members of the British Rorschach Society use is the Comprehensive system (Exner, 2003). We are aware of the Rorschach Performance Assessment System (Meyer, Viglione, Mihura, Erard & Erdberg, 2011) but most of our members do not use this system for a variety of reasons.
