1 POLYGRAPH PCSOT Goal: Increase public safety by adding incremental validity to risk-assessment, riskmanagement, and treatment-planning decisions made by professionals. Polygraph support to a Containment Approach Detection of involvement in or abstinence from problem behavior Increase disclosure of problem behavior Deterrence of problem behavior Polygraph Limitations Test results relate to what the examinee believes. Not everyone in suitable for testing. Physiologically (Including age) Psychologically (Emotions and Mental Capacity) Clarity of Issue(s) being tested. Number of Issues being tested. Polygraph Test Types Specific Issue Tests Single Issue Multi-facet Tests Multiple Issue Tests 1

2 Successive Hurdles Refers to the use of multiple testing stages before reaching a diagnostic conclusion Screening tests Diagnostic tests Based on the assumption that all tests are imperfect Attempts to optimize test sensitivity at early stages Reduce false-negative errors Optimize test specificity at later stages Correct and reduce false-positive errors Polygraph Jargon Exploratory Tests = Screening Tests Most PCSOT exams are screening exams Screening Tests Optimized for sensitivity Sensitivity = ability to notice the issue of concern Sensitivity = sensitivity to deception Reduce false-negative error FNs are the greatest concern to the community Cost-effective and efficient 2

3 Screening Tests (cont.) Any test conducted in the absence of a known issue No known incident No known allegation No known reason to suspect involvement Often multiple issue (mixed issue) Sometimes single issue Number of issues does not define a screening or diagnostic test Screening Polygraph Techniques Modern MGQTs AFMGQT version 1 AFMGQT version 2 Utah MGQT Backster Exploratory Reid-type MGQTs Army MGQT Reid GQT (Reid Technique) Marcy Technique (Marcy MGQT) Arthur Technique PCSOT Screening Tests Maintenance Exam Sex Offense Monitoring Exam Sexual History Exam I - Victims Sexual History Exam II Compulsive Behaviors 3

4 Maintenance Examination Investigate compliance with rules and conditions of supervision and treatment Deterrence / Catch them if you can Time of Reference (TOR) 4-6 months (12 max) Collection of Information No IO / IOI / PA / SH Questions (Frame of Reference (FOR) Maintenance Examination (2) Exam Targets: Sex with unreported persons Use of porn Masturbation activities and fantasies Unauthorized contact with underage persons Use of alcohol / drugs Etc.

7 Diagnostic Tests (cont.) Known issue Known incident Known allegation Subjects are selected due to their suspected involvement Allegation Witness Evidence Symptoms Diagnostic Tests (cont.) Usually a single issue test Intended to determine the presence or absence of a single issue or condition of concern Diagnostic test is not determined by the number of issues, but by the presence of a known issue Some screening tests are single issue screening tests More Polygraph Jargon Specific issue = diagnostic test Single issue = diagnostic or screening test Depends on the presence or absence of a known issue Depends on the presence or absence of a known issue Known incident Known allegation Reason to suspect the person's involvement Event-specific 7

10 Test Results LOOKING FOR DECEPTION Positive = something found Negative = nothing found Not Sure = inconclusive Test Errors False Negative Greatest concern to the community False Positive Greatest concern to the individual Inconclusive Results Inconclusive = No Opinion A test result (professional opinion) cannot be an error when there is NO OPINION The need for resolution is NOT SATISFIED 10

11 Results Screening and Diagnostic Exams Screening Exam Negative result is conclusive Positive result requires further investigation before a diagnosis can be confirmed Inconclusive result requires further investigation before a diagnosis can be ruled-out Diagnostic Exam Positive result is a basis for action Negative results require no action Inconclusive results are an insufficient basis for action Polygraph Results Screening Exams Significant Reaction (SR) = Positive No Significant Reactions (NSR) = Negative Inconclusive or No Opinion = Not Sure Diagnostic Exams Deception Indicated (DI) = Positive No Deception Indicated (NDI) = Negative Inconclusive or No Opinion = Not Sure Polygraph Professional Standards APA & ASTM (International) Exam Duration (90 min. plan / execution) Number of exams annually per examinee (4) Number of exams per day (5 max. / 3 if SH) Ethical / professional roles Validated Techniques Maximum of 4 relevant questions 11
