Objective To explore factors that affect the assessment of sexual self-defense capacity and to evaluate the effect of social functions on sexual self-defense capacity in patients with mental retardation. Methods A 1∶1 matched case-control study was carried out, which included 174 sexual assault cases, 87 with mental retardation and 87 without mental retardation. A record of forensic psychiatry assessment designed by ourselves was used to collect the general characteristics. Wechsler Adult Intelligence-Rerisedin China (WAIS-RC) was used to determine the intelligence quotient. Rating Scale of Intellectual Disability (RSID) and Global Assessment Function (GAF) were used to assess social functions. Results Besides factors such as culture, occupation, knowledge about sex and payment claim, the scores of GAF and RSID were also related to the assessment of sexual self-defense capacity. Moreover, the correct ratio of discrimination was 73.1% (yes), 66.9% (impaired) and 87.2% (no), respectively, and the general correct ratio of discrimination was 78.1%. Conclusion Not only social and legal factors but also the level of social functions should be considered in the assessment of sexual self-defense capacity. Therefore, it might be concluded that multiple discriminant analysis can be useful when assessing the sexual self-defense capacity of patients with mental retardation.
Objective To compare the incidence of social function disorders in head injury patients with and without craniocerebral injury and to explore the value for mental identification. Methods SDSS (Social Disability Screening Schedule), GAF (Global Assessment Function) and GAS (Global Assessment Scale) instruments were used to test the social function of 56 patients without craniocerebral injury and 55 patients with craniocerebral injury. Results One hundred and eleven patients with head injury were included and identified as head injury with or without craniocerebral injury by CT or MRI. The incidence of social function deficit, tested by using SDSS instrument, was 33.9% (19/56) in patients without craniocerebral injury and 45.5% (25/55) in patients with craniocerebral injury respectively. There was no statistically significant difference between the two groups (χ2=1.544, P=0.214). This was also no statitical difference in both GAS group (t=0.021, P=0.983) and GAF group (t=0.391, P=0.697). Conclusions The limited evidence showed that the incidence of social function deficit of the head injury patients combined with craniocerebral injury is higher than those who without craniocerebral injury, but the difference between the two groups has no statistically significant difference.We could not detect a difference in the incidence of social deficit between those head injury patients with or without craniocerebral injury ones.
ObjectiveTo explore the characteristics of the criminal cases assessed by forensic psychiatry expertise in order to provide evidence for guiding forensic psychiatric practice, preventing and reducing criminal acts of patients with mental disorders. MethodsWe collected information of 3 720 criminal cases assessed in Forensic Psychiatry Department of Sichuan University, China from January 1997 to December 2011 by using the self-made questionnaire, and analyzed the demographic data, criminological characteristics and expert consensus of psychiatric diagnosis and legal ability. ResultsOut of 3 720 criminal cases, 3 211 (86.3%) were male, and 3 022 (81.2%) were between 18 and 45 years old. A total of 1 683 (45.3%) were married or remarried. A total of 3 178 (85.4%) were under junior middle school, and 3 221 (86.6%) were farmer or unemployed. Schizophrenia (46.7%), without psychosis (13.8%), mental retardation (9.6%) were the top three kinds of diagnosis. Homicide (42.7%), intentional injury (21.5%) and rape/indecency (8.1%) were the main crimes. A total of 1 616 (43.4%) were irresponsible, and 1 172 (31.5%) were with full responsibility. There was a significant correlation between the number of criminal cases in every year and years (rS=0.94,P=0.00), and significant correlation was also found between the percentage of mental disorder caused by drugs and years(rS=0.84,P=0.00), as well as the percentage of mental retardation and years(rS=0.72,P=0.00). ConclusionThe number of cases shows an increasing trend in forensic psychiatry assessment over years. Most of the suspects of criminal responsibility are young and middle-aged male with low level of education, farmer or unemployed. The top three diagnoses are schizophrenia, without psychosis and mental retardation.
