Objective:To compare performances of Wechsler Memory Scale(WMS)and Clinical Memory Scale(CMS),to explore applicability of WMS and CMS in the different degree traumatic brain injured patients.Methods:206 patients were tested with WMS and 300 with CMS,and completed clinical diagnosis for all,to compare the performances.Results: ①There was no significant differences in the MQ between the two groups in the normal、marginal memory impairment, there were significant differences in the mild memory impairment.②There were remarkable variance between the MQ and the clinical diagnosis,WMS was even more variant.Conclusion:①There is similar outcome between WMS and CMS in the patients with normal、marginal memory impairment,CMS shows more applicable in the patients with more severe mem- ory impairment.②It is not correct to diagnose memory defect degree with MQ without more clinical information.

Objective To examine the dissimulation in memory test by event-related potentials (ERP).Methods Recording the ERP of 20 students in the choosing tasks according to Binomial Forced-Choice Digit Memory Test (BFMDT) in three situations including reality,dissimulation and forced wrong choose. Results The reaction time was lengthened gradually by the situation of reality ( 681 ± 21 ) ms, dissimulation ( 741 ± 25 ) ms and forced wrong choose( 946 ± 31 ) ms (F= 115.73, P = 0.000). The main components in ERP waveforms, N2 ( 180 ～184 ms) and P2 ( 214 ～ 243 ms) had higher amplitudes in situations of dissimulation and forced wrong choose than that of reality. The amplitude of N2 showed significant difference in three groups(F=6. 896, P＜0.01 ). The amplitudes were increased gradually by the situation with reality( -0.376 ± 0.58 )μV, dissimulation( 0. 86 ± 0.71 )μV and forced wrong choose( 1.77 ±0.82)μV. Conclusion ERP may be an electrophysiological index of the intention of dissimulation in memory test.

Objective:To explore the effects of cognitive impairment on the performance of Binomial Forced-Choice Digit Memory Test (BFDMT). Methods: Subjects were screened by Mini-Mental State Examination (MMSE) and the brief form of WAIS-RC.BFDMT was administered to 38 dementias and 19 controls.Results: (1) There was no significant difference in the scores of two dimensions and total score of BFDMT between dementias and controls. (2) There was significant difference in the difficult item scores and the total score among three groups of subjects with different levels of IQ. The difficult item scores and the total score of the subjects with IQ 70～84 were significantly higher than those with IQ 50～69 and IQ 34～49. There were no significant differences among all groups in the easy item scores. (3) The false positive was 15.8% by the cutoff scores of total scores of BFDMT and increased with the decline of IQ. Conclusion: The performance of BFDMT is somewhat influenced by intellectual defect. A high false positive of BFDMT particularly happens in the patients with severe intellectual decline.

Objective: To develop the norms of Chinese Words and Vocabulary Discerning Test (CWVDT). Methods: According to the principle of stratified proportional sampling,a total of 1605 adult subjects from 17 cities and their surrounding rural areas of China was measured by CWVDT. Results: ①There was significant difference in two dimensions scores and total score of CWVDT between city and countryside(P0.05). Conclusion: The nationwide norms of city and countryside with educated degrees on CWVDT have been developed and with a good representation.

Objective:To explore the executive function of neuroleptic -naive and short -term medicated onset schizophrenic patients.Methods:55 drug naive patients and 49 patients with schizophrenia medicated for one month and 60 normal controls were administered the Wisconsin Card Sorting Test(WCST) to study the executive function.Results:Compared with the controls,neuroleptic-naive patients and medicated patients showed higher level in the number of total trials,perseverant errors,random errors,the rate of error responses and the rate of random errors,while they showed lower level in the number of categories,correct trials and the rate of correct responses.There was no significant difference in WCST between the neuroleptic-naive patients and medicated patients.Conclusion:Neuroleptic-naive and short-term medicated onset patients with schizophrenia may have executive dysfunction.

Objective: To evaluate Raven's Standard Progressive Matrices (RSPM) for assessing validity of test performance. Methods: To compare the results of RSPM between head injured patients with and without malingering. Results:①There were significant differences in the performance between the two groups of patients in subtests A,B,C and D of RSPM. There was no significant difference on subtest E. ②Based on p

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

Objective To investigate prevalence of long-term mental disorders following traumatic brain injury (TBI) in 4 ～ 13 years. Methods Of the 4287 patients with traumatic brain injury by systematic sampling.675 subjects were screened by the manual of the psychiatric consequences following traumatic brain injury. The final diagnoses of mental disorders were determined by two advanced psychiatrists based on CCMD-3 on the criteria of organic mental disorders. Results ① Of the 675 subjects with traumatic brain injury,206 had satisfied diagnosed criteria of one or more organic mental disorder syndromes by CCMD-3, and with dementia 17.48% , amnestic syndrome 1. 04% , personality or behaviour change 13. 84% , psychotic syndrome 1. 19% , depressive syndrome 7.41% ,manic syndrome 0.30% ,hysteric syndrome 0.98% , neurotic syndrome 10. 22%. ②The incidence of the mental disorders in the subjects with severe TBI was significantly higher than that of moderate and mild TBI,separately 66.01% (134/203) ,18.04% (46/255) and 11.98% (26/217 ),λ2 =109.03 and 129.82 separately(P< 0.01). ③The incidence of the personality or behaviour change in male was significantly higher than that of female, separately 15.31% and 6.98% (λ2 =5.65, P<0.05). The incidence of the neurotic syndrome in female was significantly higher than that of male, separately 15. 12% and 8. 55% (λ2 = 6. 02, P < 0.05). Conclusion The high incidence of the mental disorders in the patients with TBI should not neglect. There are more high occurrence rate with more severe degree of brain injuries.

Objective To examine the reliability and validity of compensative neurosis assessing scale (CNAS) and in order to develop the quantitative assessing method for distinguishing the compensation neurosis from malingering and typical neurosis. Methods The reliability and validity of the scale was tested based on the subjects including the cases involved forensic problems, the patients with typical neurosis in general psychiatric 0.944. The test-retest reliability was more than 0.820. The scorer reliability was more than 0. 812. The total accu-racy rate of CNAS for evaluating three groups of subjects based on the experts diagnosis, and with 91.2% of speci-ficity and 79.3% of sensitivity for evaluating compensation neurosis. Condusion The CNAS has acceptable psy-chometrics properties on reliability and validity. It will provide method to distinguish the compensation neurosis from malingering and typical neuroses.

Objective To test the cut-off point and empirical validity of psychiatric assessment scale of cognitive and volition capacity for suspects in crime (PASCVC).Methods One thousand of forensic psychiatry cases from fifteen bodies of the seven administrative regions in China were collected for forensic assessment by the three scales of PASCVC,DCRRS and CRRSV in August 2009 to December 201 l.in all cases by the appraiser to make six grade judgment of the cognitive and volition capacity including completely lost,lost most,partial loss,partial loss of a small,slightly damaged and normal.Results ① Based on the results of frequency distribution table: complete loss of demarcation divided ＜ 56 minutes,lost most 57-66,partial loss 67-76,partial loss of a small 77-87,slightly damaged 88-100 and normal ≥ 101.②The correlation coefficient of six demarcation point grading assessment results and expert opinion was 0.939(P＜0.001).③PASCVC consistency with DCRRS and CRRSV,the Kappa values were 0.838 and 0.835 respectively(P＜0.001).④Discriminant function were established by two methods of PASCVC and expert assessment,the correct rates of PASCVC and expert judgment on back substitution determine were 86.9％ and 85.1％.Two kinds of classification results,the Kappa value of 0.857 (P＜0.001).Conclusion PASCVC has good empirical validity,and can be used as an objective assessment tool for forensic assessment of criminal cognitive and volition capacity.
