To address the lack of a diagnostic interview that was suitable for co-morbidity research, the PRISM was begun in 1990 with a grant from the National Institute of Alcohol Abuse and Alcoholism to Dr. Deborah Hasin and her group at Columbia University and New York State Psychiatric Institute. This early version of the PRISM was based on DSM-III-R criteria and provided new features specific to co-morbidity diagnosis. Following the publication of DSM-IV, funding for the development and field testing of an updated version of the PRISM (version 6.0) was provided through a grant awarded to Dr. Hasin from the National Institute on Drug Abuse. Before 2009, the PRISM was administered using a paper version of the interview. Since then, the computerized version of the PRISM for DSM-IV disorders (PRISM-CV-IV) has been developed and fully tested.
