Voice Stress Analysis can be used to determine the best avenue of investigation of any possible deviant behaviour by verifying the truth spoken by the subject.
Single incident issues are analysed utilising the Integrated Zone of Comparison Technique (IZCT) wherein the questioning protocol requires the reactions to three Control Questions to be compared to that of their paired Relevant Questions. Irrelevant & Sacrifice Relevant questions are all strategically placed. Three recordings are captured to gain an average reaction.
Multiple incident issues are analysed utilizing MGQT wherein the questioning protocol requires the strongest Control Question reaction to be compared to the reaction to all Relevant Questions. Four recordings are captured.
Screenings are regular, single recording examinations containing several Relevant Questions and two Control Questions. This technique is proposed when subjects need to be tested regularly for deviant behaviour in their employment environment. The regularity of such examinations can be bi-annual or even as regular as quarterly.
Pre-employment examinations should be conducted prior to the possible employment of any new candidate. These single recording examinations containing several Relevant Questions and two Control Questions should include topics such as substance use, verifiable qualifications, theft, involvement in crime, etc.
