"A comprehensive study on Validity and Reliability of Detection of Deception
conducted by D.C. Raskin, G.H. Barland, and J.A. Podlesny (1978) for the
National Institute of Law Enforcement and Criminal Justice that included
fi eld studies and laboratory experiments concluded that the optimal score
threshold using the Utah Zone Comparison Technique format was a fixed
threshold of +/-6 which would result in an accuracy rate from 88 to 90 percent
with an inconclusive rate of approximately 9 percent. Further, the study shows
that as the scores increase, there is a moderate increase in accuracy reaching
approximately 98 percent, particularly from +/-9 to +/-12, but at the expense
of an increase in inconclusives. Furthermore, in the Matte, Reuss 1989a fi eld
study, tables 10a1, 10a2, 10b1, 10b2 and 10c show that as the scores increase
the probability of error decreases, hence an increase in accuracy.
