Study On The Relationship Between The Criminological Characteristics, Drinking Factors And The Capacities Of Criminal Responsibility For The Alcohol-related Offender

Objective: To investigate the relationship between the criminological characteristics,drinking factors and the capacities of criminal responsibility for the alcohol-related offender. To analyze the similarities and differences between the two types of alcohol-related offenders. To explore the relevant factors leading to alcohol related offenses.Methods: We applied the forensic psychiatric expertise registration scale which include the demography factors and criminal items; drinking register scale; alcohol screening scale; social disability screening schedule ( SDSS). We collected 106 cases which meet the criterions of alcohol-related diagnosis and 125 cases without mental disorder, the former was further divided into ordinary drink group (72 cases) and chronic alcoholism group (34 cases). A case-control method was adopted, and the statistical description,T-tests, ANOVA, chi- square test,pearson correlation and logistic regression analysis were used in the study.Results: 1. The criminological characteristics of alcohol-related offenders: There were statistical difference between alcohol-related group and control group in relation (X~2=l7.955, P=0.006), induced incident (X2=25.070, P=0.000), criminal motives (X2=68.292. P=0.000), criminal means (X2=30.203, P=0.000), criminal time (X2=25.395, P=0.000), criminal purposes (X2=34.389. P=0.000), forgotten after committing(X~2=63.745, P=0.000), criminal times (X2=7.106, P=0.011) and criminal record (X2=7.081. P=0.029). And in the alcohol-related group, 84.0% alcohol-related offenders committed violent crime, and the accomplished offense rate was 95.3%.The ordinary drinkers who were familiar with the victims account for 58.4%. 48.6% of the ordinary drinkers had induced incident before committed, and 61.5% of them had realistic motives. 45.4% of the group prepared for before committed, and 20.8% of them optioned criminal time. The offenders whose aim was definited account for 81.9%, and 56.9% of them toke a certain anti-detection means.12.5%of the offenders committed crimes more than one time, and 15.3% of them with a criminal record. 85.5% of the chronic alcoholism group were familiar with the victims.32.4% of the group had induced incident before committed, and 44.1% of them had realistic motives. 45.4% of the latter group prepared for before committed, and only 5.9% of them optioned criminal time. The offenders whose aim was definite account for 50.0%, and 26.5% of them toke a certain anti-detection means. 29.4%of the offenders committed crimes more than one time, and 20.6% of them with a criminal record. 2. The drinking factors of alcohol-related offenders: 72.2% of the ordinary drinkers mainly drank wine. The offenders whose average drinking capacity≤250ml accounted for 58.3% of the ordinary drink group, and the average drinking life span was 9.6944 years. In the ordinary drink group, occasional drinkers account for 30.6%, and 69.4% of the group whose purpose for drinking was social intercourse. In the past, 44.4% of the ordinary drinkers had taken impulsive behavior. Meanwhile, 94.1% of the offenders in the chronic alcoholism group mainly drank wine. The drinkers in the group whose average drinking liquor > 250ml accounted for 73.5%, and the average drinking life span was 20.5588 years. In the latter group, all of them drank frequently or kissed the cup from day to day, and 69.4% of the group whose purpose for drinking was dependence, and in the past, 44.4% of them had taken impulsive behavior.3. The capacity of criminal responsibility and its related factors: All of the ordinary drink group was identified complete criminal responsibility, and 55.9% of the chronic alcoholism group was assessed partial criminal responsibility while the other 44.1% was assigned no criminal responsibility (X~2=106.000, P=0.000). After logistic regression analysis, we found that the induced incidents (b=0.948. P=0.005), the choice of committed time (b=2.505. P=0.022) and the reaction after committing (b=0.346. P=0.018) were associated with criminal responsibility; and the drinking capacity (b=1.217. P=0.004), the drinking age (b=0.112. P=0.000) and the frequency of drinking (0.659, P=0.028) were also associated with criminal responsibility.Conclusions: The evaluation of criminal responsibility about the alcohol-related offense in forensic psychiatry occupy a certain percentage. Most of the cases were violent cases, and the successful rate was high. More ordinary drinker had a certain realistic motive and chose the commit time and target; and had certain self-protection awareness after committing. Meanwhile, more patients of the Chronic alcoholism had not clear realistic motive, and did not prepare before committed, and lacked the sense of self-protection after committing. In the aspect of drinking factors, there were more unhealthy drinking behaviors in the group of chronic alcoholism.All of the ordinary drink group was assessed complete criminal responsibility, and most of the chronic alcoholism group was judged partial criminal responsibility or no criminal responsibility. The assessment of criminal responsibility was mainly affected by the induced incidents, the choice of committed time, the reaction after committing, the drinking capacity, the drinking age and the frequency of drinking.
