Objective To test the reliability and validity of the rating scale of social function deficit due to mental disorders (SSFD-MD). Methods 1003 cases with mental disability evaluation were tested by SSFDMD. At sametime, 100 cases of 1003 cases were test-retested and back to back tested by two examiners. 300 cases of 1003 cases also were tested by social disability screening schedule( SDSS),scale of social function for psychosis inpatients(SSPI),global assessment function(GAF) ,the brief psychiatric rating scale(BPRS) ,WH0 disability assessment scale Ⅱ (WHO-DASⅡ ), adult rating scale of mentally disabled ( ARSMD) and rating scale for extrapyramidal side effects (RSESE). Results ①The Cronbach's α coefficients of the total score and all dimensions of SSFD-MD were more than 0.90. The test-retest reliability ranged from 0.67～0. 83 ,and the scorer reliability were 0. 87～0.97. ②The correlations between item scores ranged from 0.46 ～0.74(P＜0.01). The correlations between the factor scores and the total scores ranged from 0.73～0.87(P＜0.01). To extract five full-scale principal components after orthogonal rotation to maximize variance,the cumulative total variance explained was 82.25%.There were highly correlations between SSFD-MD and SDSS.SSPI and GAF,respectively ( r = 0. 71,0.72 and 0. 78). There were moderate correlations between SSFD-MD and BPRS WHO-DAS II ARSMD,respectively(0.62,0. 50 and 0.46). There was a low correlations between SSFD-MD and RSESE ( r = 0.22) ,but all correlations were significant(P＜0.01). Conclusion SSFD-MD has acceptable psychometrics properties on reliability and validity.

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 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 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 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.
