OBJECTIVE: To create an instrument to determine the mental disorder offenders' competency to stand trial, which is according with the Chinese legal system. METHODS: Integrating the foreign instruments and the Chinese criminal jurisprudence, and combing the authors' forensic psychiatric experience, the research team created an instrument which was called Competency to stand trial Determining Instrument firstly, then used the instrument in practice, in the end the validity and reliability of the instrument were inspected, and through an diagnostic test, the feasibility of the instrument was evaluated. RESULTS: Split-half and homogeneity reliability of the instrument is 0.9366 and 0.9213 respectively, the correspondence of the conclusion between the instrument and the expertise is 0.704. Except the sensitivity is 0.6097, all the other diagnostic index are over 0.80. CONCLUSION The Competency to stand trial Determining Instrument is feasible.

It is very difficult to identify the relationships between tangle events and accompanied mental disorders. There are often different descriptions of the same controversial conclusion. This thesis introduce the conception of contribute degree and discusses the causality of tangle events and accompanied mental disorders in forensic mental trauma assessments.

OBJECTIVE: To study the intelligence of criminals with no psychosis diagnosed with forensic psychiatry. METHODS: The intelligence test results in 88 criminal cases with no psychosis and in 89 criminal cases with schizophrenia were compared. RESULTS: There were no significant statistical differences between two groups with respect to their sex, age, education, occupation, marital status, and criminal type. The average intelligence quotient (IQ) of no psychosis group was significantly higher than that of the schizophrenic group, but was significantly lower than the normal. There was no significant statistical difference between the subgroups claiming as either suffering or denying psychosis. CONCLUSION There is a mild impairment in the intelligence in no psychosis group.

OBJECTIVE: To explore social function in assessment of self-defense capability of patients with mental retardation against sexual assault. METHODS: The data of 125 sexual assault victims with mental retardation were collected according to our forensic psychiatry assessment criteria. Mental retardation was rated with WAIS-RC, GAF, and the rating scale of the intelligence disability. RESULTS: There were significant differences in occupation, marital status, education, knowledge about sex, and history of pregnancy among the patients with different levels of self-defense capability. The kappa values of the rating scale score of the intelligence disability, GAF, and IQ were 0.710, 0.661, and 0.494; the kappa values of that and self-defense capability were 0.538, 0.472, and 0.316 respectively. CONCLUSION The level of social function is very important in the assessment of self-defense capability in patients with mental retardation.

OBJECTIVE: To explore potential application of Diminished Criminal Responsibility Rating Scale (DCRRS) on rape offenders. METHODS: The DCRRS was used retrospectively to study 77 cases of rape offenders. They were divided into three groups according to the degree of diminished criminal responsibility. RESULTS: There were significant differences in rating scores among three groups (mild group 21.32+/-5.56, moderate group 25.92+/-5.19, and major group 29.54+/-4.62), and 16 of 18 items showed good correlation with the total scores of the scale (r=0.256 to 0.611), 7 factors were extracted by the factor analysis and their cumulative squared loadings was 75.784%. CONCLUSION The DCRRS is valid and reliable in a in assessment of criminal responsibility schizophrenic rape offenders.

OBJECTIVE: To explore the application of Diminished Criminal Responsibility Rating Scale (DCRRS) to mental retardation offenders. METHODS: The DCRRS was used to 121 cases of mental retardation offenders who were divided into three groups according to the degree of their diminished criminal responsibility. RESULTS: There were significant differences in rating score among the three groups (mild group 22.12+/-4.69, moderate group 25.50+/-5.48, major group 27.59+/-5.69), and 17 items had good correlation with the total score of the scale with the correlation coefficient from 0.289 to 0.665. Six factors were extracted by the factor analysis, and 69.392% variation could be explained. CONCLUSION The DCRRS has rational items, its total score could show the difference among the three degree diminished criminal responsibility of mental retardation offenders.

The suicide were analyzed depending only on the death scene and cadaver features but not on the psychological autopsy (PA) that also enables the determination of the manner of death in China for a long time. There are significant differences between PA and the traditional risk assessment of suicide. The goals of PA are to find out the features of individuality, the patterns of behavior and the possible motives of suicide. The methods of PA involve investigating, collecting and analyzing all related information of the deceased. There are many limitations of PA in application mainly due to the lack of the standard procedures. Although an improved procedure has recently developed by Berman, many problems need to be solved before the actual application of PA in China.

OBJECTIVE: To explore the basis to discriminate diminished criminal responsibility. METHODS: Chi-square test, one-way ANOVA test, factor analysis and stepwise discriminant analyses were conducted for 92 cases which were divided into three groups according to the degree of diminished criminal responsibility. RESULTS: There were significant differences in the type of crime and rating score among three groups. The factor 1 reflecting the premeditation and preparation before crime was the most important of all factors. Realistic motivation, time selectivity of offending, emotion during the crime, understanding the nature of the behavioral, impairment of life ability and impairment of reality testing were the discriminating factors of grades division in diminished criminal responsibility. CONCLUSION The diminished criminal responsibility in mental disorder offender could be divided into three grades.

METHODS: The DCRRS were used respectively to 325 cases of schizophrenia offender which were divided into three groups according to the degree of criminal responsibility. RESULTS: There were significant differences in rating score among three groups (mild group 21.16 +/- 4.17, moderate group 25.87 +/- 5.43, major group 29.35 +/- 4.60), and all items have good correlation with the total score of the scale. 6 factors were extracted by the factor analysis, and their cumulative squared loadings is 68.485%. CONCLUSION The diminished criminal responsibility in schizophrenia offenders could be divided into three grades.

OBJECTIVE: To explore the feasibility of the criminal responsibility rating scale for suspects with mental retardation. METHODS: Ninety six suspects with mental retardation were evaluated by trained professionals according to the scale, and the results were compared to the expert's opinion. RESULTS: The scores of three groups (no, diminished, and responsibility group) were 12.25 +/- 2.06, 28.62 +/- 4.57, 44.41 +/- 5.17 respectively and were significant different among them. All items had statistical correlation with the total score of the scale. Five factors were extracted by means of the factor analysis and they could explain 70.919% of the variation. The accuracy of retrospective cumulative square was 92.7%. CONCLUSION The Criminal Responsibility Rating Scale has good reliability and validity, and can be used as a reference in assessment of criminal responsibility.
