A REVIEW OF QUESTION FORMULATION IN POLYGRAPH LITERATURE OF POLYGRAPHIC METHOD FOR COUNTERPRODUCTIVE BEHAVIOUR INDEX PROFILING Ahmad Zaki Abu Bakar a, Rose Alinda Alias b and Hashim Bin Hj Yusoff c, Faculty of Computer Science and Information System Universiti Teknologi Malaysia, 81310 UTM Skudai, Johor Tel : , +60127081170 Fax : (607)-521-8174, E-mail: [email protected], [email protected], [email protected] ABSTRACT The research of Polygraphic Method for Counterproductive Behaviour Index Profiling is divided into four phases namely i. Question Formulation, ii. Polygraph Testing, iii. Polygraph Index Profiling, and iv. Historical Profile Repository. The most importance aspect for the success of this research is the question formulation phase. One of the most important aspects of polygraph testing is the formulation of questions. The Question Formulation phase which consist of the technical, organization and personal components play a very important role in the success of the research and the formulation of the framework. APA policies, guidelines, requirements and instrumentation play an important role. The types, needs and goal of the organization determine the attributes to be polygraphed or tested. The profile of the examiner, the examinee (subject), the interpreter, the human resource executive and the question formulation of multilingual Malaysian multiracial based play the dominant roles in the question formulation phase. High security risks and high integrity risks organizations require the appointments of personnel to important key positions to be conducted in a stringent manner with many levels of screening to determine the best person with the best integrity for the right job avoiding wrong hiring. The requirements of question formulation phase must be met with, to achieve the best result of the system.

The 80 research projects listed, published since 1980, Research that utilized field procedures and involve 6380 polygraph examinations or sets of experienced examiners has consistently charts from examinations. Researchers demonstrated that subjects who are telling the conducted 12 studies of the validity of field truth to relevant questions focus their emotional examinations, following 2174 field responses to control questions, whereas subjects examinations, providing an average accuracy of who are lying to relevant questions focus their 98%. Researchers conducted II studies involving emotional responses away from control the reliability of independent analyses of 1609 questions and to the relevant questions (Capps, sets of charts from field examinations confirmed 1991).

Currently, various tools including Polygraph Testing have been utilized by many organizations all over the world to assist them in the pre-employment selection process to detect possible counterproductive behaviours in short- listed candidates.
