Few evaluators using
the Rorschach acknowledge its limitations. If the Rorschach is
used, its limitations should be clearly noted unless the Exner system is
used. And then, it is necessary to say what is being scored by the Exner
system. But often,
idiosyncratic interpretation techniques are used to form conclusions and make
recommendations which affect the lives of people.
There is no empirical support for the validity of the
Rorschach, except when the Exner system is used. Reviews in the Buros
Mental Measurement Yearbook for every year in which this test has been
reviewed state that there is no research demonstrating its validity. For
example, in the Eighth Mental Measurements Yearbook Peterson concluded: "The general lack of predicted validity for the
Rorschach raises serious questions about its continued use in clinical
practice."
