A Commentary on “Developments in the Rorschach Assessment of Disordered Thinking and Communication” (Kleiger & Mihura, 2021)

“Why on earth would one use the Rorschach to assess disordered thinking?” was
the almost Pavlovian reaction of the second author to the request to write this
commentary. This uninformed response was markedly changed after reading
the excellent contribution by Kleiger and Mihura (2021), as well as the research
they cite. The authors convincingly argue for the reliability and validity of a set
of Rorschach scales that assess thought disorder. Hence, we see no reason why
one shouldn’t use these scales for this purpose.
Apart from reliability and validity, the question “why use the Rorschach?”
encompasses utility. This deserves attention if one wishes to convince new
researchers and clinicians to start using the instrument. We will review current
instruments for disordered thinking and communication and discuss the hypothet-
ical (incremental) utility of the Rorschach in research and in clinical practice
