Research Division Staff. Psychophysiological detection of deception accuracy rates obtained using the Test for Espionage and Sabotage (TES). June, 1995, Report No. DoDPI94-R-0009. Department of Defense Polygraph Institute, Ft. McClellan, AL 36205.

Previous research conducted by the Department of Defense Polygraph Institute (DoDPI) indicated that the decisions of examiners who administered the Test for Espionage and Sabotage (TES), were significantly more accurate at identifying programmed guilty examinees than were the decisions of examiners who administered either of two Counterintelligence Scope Polygraph (CSP) formats. The new format differs from previous security screening formats in that: (a) the number of issues being tested is reduced; (b) the number of repetitions of the questions used to calculate question scores is restricted to three; (c) between test stimulation is eliminated; (d) the order of questions within the question sequence cannot be altered; (e) each relevant question is compared to the same control questions; (f) the pretest is brief, more standardized and follows a logical sequence of information presentation; and (g) the Directed Lie Control (DLC) questions eliminate many of the problems associated with Probable Lie Control (PLC) questions. The procedures utilized during this study were identical to those in the previous study, but only the TES format was utilized. The replication was done in order to further validate the accuracies of the examiners' decisions in identifying programmed guilty and innocent examinees, when the TES format was administered. The data collected in this study were evaluated using the new criteria developed from the previous study. Ten certified examiners from the Office of the Secretary of the Air Force conducted 88 examinations. The examiners had been trained to administer the TES and had been utilizing the TES when conducting security examinations. Ninety-eight percent of the innocent examinees and 83.3% of the programmed guilty examinees were correctly identified.
