Binomial Forced-Choice Digit Recognition Test in Identification of Dissimulation of Intelligent Deficit in Asking Compensation after Traffic Accident / 中国心理卫生杂志

ABSTRACT

Objective: To explore the validity of Binomial Forced-Cho ic e Digit Recognition Test (BFDRT) in detecting dissimulation of intellectual defi cit Method: 57 subjects with history of head injury in traffic and diagnosed as malingering in forensic assessment received BFDRT before the fo rensic assessment 66 subjects with similar head injury of other reasons were c o llected as control Discrimination analysis was done to determine the role of B F DRT in identifying malingering Result: The results of BFDRT sh o wed that there were significant differences of the two dimension scores, total s core and quotient of response bias between the two groups The accuracy of disc r imination was 92 7%-100%, with the rate of false positive 0-3%, the rate of fal se negative 1 8-14%, when the cut-off point was 11 on easy items, 7 on difficul t items and 18 on total score The total score had the highest accuracy in discr i mination Conclusion: BFDRT is useful in identifying dissimulat ion of intelligent deficit in asking compensation after traffic accident
