An Axciton Computerized Polygraph System (Axciton Systems, Houston, Texas) and the Lafayette Instrument LX-4000 (Lafayette Instrument Co., Lafayette, Indiana) were utilized. The examiner was certified by the Colorado Sex Offender Management Board. For purposes of score reliability and validity confirmation, the results were both scored by hand and scored using the Johns Hopkins Applied Physics Laboratory Polyscore computer scoring algorithm (Heil, Ahlmeyer, Simons, & English, 1999). Hand scoring is recognized by the American Polygraph Association as the most accurate and reliable method of scoring. It was the only method used to evaluate the data. The algorithm was used as a quality control check of the hand scoring method. Subjects provided a separate informed consent before the first polygraph examination. The test was administered in a private office. The examination took an average of two hours. Subjects were tested every three months. Polygraph was standardized by an American Polygraph Association approved test procedure and was administered by a single experienced examiner, who was blinded to the dosing protocol. The polygraph examination process contained pretest and posttest components. The examiner worked closely with the psychotherapist in developing appropriate polygraph questions for confirmation of the disclosed number of victims and offenses, discovery of new offenses, and or compliance with study conditions. This study examined past victim and offense admissions data, as well as responses evaluating 30 paraphilias (Table IV). The pretest established which questions the examiner would ask based on the subject’s self report of new admissions of past offending or the absence of accountability statements for known offending behaviors (identified in prison histories). The subject’s cardiovascular, respiratory, and galvanic skin resistance were assessed in response to three specific key questions:
