The preliminary study of psychophysiological test technique in the simulative identification of artificial injury and malingering / 中国法医学杂志

Objective To explore the application value of psychophysiological test technique in identification of artificial injury and malingering. Methods CQT test was conducted on 50 students with camouflaged pain and tympanic membrane perforation, respectively, using Tongfang Shenhuo Polygraph Tester (TH 4.0.0.15). T-test and χ2 test were adopted for data analysis. Results The accuracy rate of honest group was higher than that of lying group (P<0.01). There were no significant differences in accuracy rates between automatic scoring and manual scoring,and so were that between mask pain problems' testing and tympanic membrane perforation problems' testing. Conclusion This experiment provides a good research basis for the subsequent real case test.
