(Melton GB, Petrila J, Poythress NG, Slobogin C: Psychological Evaluations for the Courts (ed 2). New York: Guilford, 1997) recently advocated the use of the Mental State at the Time of the Offense (MSE-Offense) measure not only as a screen for insanity evaluations but also as the sole measure in "obvious" cases of insanity. Given this recommendation for expanding the role of the MSE-Offense, the current authors have evaluated the available data based on its construction and validation. We found fundamental flaws in its development and grave shortcomings in its validation. Based on these limitations, we conclude that the MSE-Offense is unacceptable under the Daubert standard (Daubert v. Merrell Dow Pharmaceuticals, Inc., U.S. 113 S. Ct. 2786 (1993)) for either the screening or determination of criminal responsibility.
