The antisocial personality seems unable to learn from his experiences that he continues to repeat his impulsive behavior even if it leads to legal prosecution. The antisocial personality cannot fully realize that what he does is actually socially unacceptable or dangerous, or that he has any responsibility to society to control his behavior. Quite often he cannot stop himself or control his unconscious impulses regardless of his supposed good intentions and the impending punishment to be inflicted upon him. RR, a 31 -year old male from Metro Manila has been in and out of jail because of multiple robberies. He was referred for psychiatric evaluation due to difficulty sleeping, restlessness, hallucinations and delusions of persecution. During therapy RR was deceitful, manipulative and without insight or remorse for his wrongdoing. He rationalized his stealing, cheating, gambling, hurting or killing of people and substance abuse. RR came to the sessions only upon court order without any intention to change or conform to societys laws and despite a confrontational stance, remained in denial, rationalized his actions and gained no insight.

OBJECTIVES: The purpose of the study was to examine the relationships between temperament and character dimensions and family environments, and to investigate the influences of those factors on the antisocial personality traits in delinquent adolescents. METHODS: The subjects consisted of 160 male adolescents detained at the public prosecutor's office on the suspicion of crimes. To assess personality dimensions and family environmental factors, the Temperament and Character Inventory(TCI) and the Family Environment Scale(FES) were completed. Antisocial personality traits were assessed by the number of antisocial personality disorder symptoms of the Personality Disorder Questionnaire-Revised. RESULTS: Most of the TCI dimensions except Reward Dependence(RD) were highly correlated with the subscales of FES. Among temperament dimensions, Novelty Seeking(NS) and Persistence(P) were significantly affected by Organization, and Harm Avoidance(HA) was influenced by Expressiveness of FES. Self-Directednss(SD) was best predicted by Organization and Achievement-Orientation. While the Independence had significant effect on Cooperativeness, Expressiveness and Achievement-Orientation best predicted the level of Self-Transcendence(ST). On factor analysis, NS, HA, SD and ST were allocated to the same factors with subscales of FES. The level of antisocial personality trait was best predicted by NS, P and SD scores of TCI, and conflict subscale scores of FES. CONCLUSION: The findings of this study suggest that not only the character dimensions but also the temperament dimensions have close relationships with family environmental factors, and that the antisocial personality traits of delinquent adolescents may developed by the interaction between temperament/character dimensions and family environments.

OBJECTIVE: Impulsivity is a core feature of borderline personality disorder (BPD) and antisocial personality disorder (ASPD) that likely arises from combined genetic and environmental influences. The interaction of the low activity variant of the monoamine oxidase-A (MAOA-L) gene and early childhood adversity has been shown to predict aggression in clinical and non-clinical populations. Although impulsivity is a risk factor for aggression in BPD and ASPD, little research has investigated potential gene-environment (G×E) influences impacting its expression in these conditions. Moreover, G×E interactions may differ by diagnosis. METHODS: Full factorial analysis of variance was employed to investigate the influence of monoamine oxidase-A (MAO-A) genotype, childhood abuse, and diagnosis on Barratt Impulsiveness Scale-11 (BIS-11) scores in 61 individuals: 20 subjects with BPD, 18 subjects with ASPD, and 23 healthy controls. RESULTS: A group×genotype×abuse interaction was present (F(2,49)=4.4, p=0.018), such that the interaction of MAOA-L and childhood abuse predicted greater BIS-11 motor impulsiveness in BPD. Additionally, BPD subjects reported higher BIS-11 attentional impulsiveness versus ASPD participants (t(1,36)=2.3, p=0.025). CONCLUSION: These preliminary results suggest that MAOA-L may modulate the impact of childhood abuse on impulsivity in BPD. Results additionally indicate that impulsiveness may be expressed differently in BPD and ASPD.

OBJECTIVE: The association of offender mental illness (including those on probation) with crime has long been the subject of social interest; however, systematic management has been insufficient. The study purpose was to analyze mental illness prevalence, proportion of first offenses and recidivism with the mental illness of those on probation. METHODS: A total of 206 adults on probation were divided into groups (first offenders and repeat offenders) and they completed self-report instruments and clinical interviews designed to diagnose mental illness. RESULTS: The mental illness prevalence among those on probation was considerably higher than that of the general population, and having mental illness was related to re-sentencing probation or recidivism. In particular, alcohol use disorder, major depressive episode, manic/hypomanic episode, and antisocial personality disorder were shown to affect recidivism. CONCLUSION: To achieve the ultimate purpose of probation, social and systematic intervention on a mental health and medical basis may be required.

OBJECTIVE: The percentage of repeat offenders is increasing among juvenile offenders in Korea. The assessment and treatment of the mental health of young offenders may play an important role in reducing the recidivism rate of adolescents. This study examined the prevalence of psychiatric disorders among adolescents on probation or parole and the risk of recidivism associated with specific psychiatric disorders. METHODS: We studied 120 adolescents on probation. The Mini-International Neuropsychiatric Interview and Conners’ Rating Scale-Revised were used to diagnose psychiatric disorders. RESULTS: Almost half of the juvenile offenders had psychiatric disorders, including alcohol use disorder (19.17%), bipolar disorder (18.33%), antisocial personality disorder (11.67%), and attention-deficit/hyperactivity disorder (10.83%). Alcohol use disorder was significantly associated with repeated offenses, but psychiatric disorders, excluding alcohol use disorder, were not significantly associated with repeated offenses. CONCLUSION: These results suggested that the development of education and treatment programs for psychiatric disorders, including alcohol use disorder, among juvenile offenders on probation or parole may help to prevent repeated criminal behaviour.

The purpose of this study is to afford basic data for planning a program to strategically prevent adolescent sexual violence by clarifying the concept of sexual violence in adolescence and investigating factors influencing the adolescent attitudes towards sexual violence. Subjects of the study were 288 adolescents between the ages of 14 to 21, living in K city in Chungnam Province. The data was collected for this study between May 30 and June 13, 2001. For this study, the following materials were used as instruments: the types of attitudes toward sexual violence developed by Nam, S. Y.(2000), the antisocial personality by Min, B. K., Choi, S. J., & Lee, G. H.(1978), the self-esteem developed by Rosenberg(1965) and interpreted by Jeon, B. J.(1974), the family support developed by Cobb(1976), the stereotyped sex role and the attitude on sexuality by Kim, E. J.(1997). The data was analyzed, using SPSS 7.5 for Windows Program, descriptive statistics, t-test, ANOVA, and discriminant analysis. The results of this study were as follows: 1. Adolescents of the first type, ones blaming social morals, amounted to 34.7%(100 subjects), the second type, ones blaming the victims, amounted to 22.3%(64 subjects), the third type, ones claiming reform of consciousness, amounted to 25.3%(73 subjects), and the fourth type, ones coping actively, amounted to 17.7%(51 subjects). 2. Attitudes toward sexual violence were influenced a great deal by the sex of the subject. 3. The study revealed that various types of the attitudes toward sexual violence was significantly different from one another, related to antisocial personality(F=2.80, P= .04). Especially the first type and the third type were most different from each other. The latter showed the antisocial personality strongly, compared with the former. 4. Discriminant analysis revealed that the most powerful predictors of attitudes toward sexual violence were the sex of the subject and whether or not they had an antisocial personality. 5. The degree of possibility of identifying a risk group of adolescents was 45.9% and the possibility of identifying a non-risk group was 73.3%. The hit ratio was 67.8%. In conclusion, the results of the study lead us to understand the type of adolescent attitudes toward sexual violence. The results will be useful to furnish a guideline for nursing intervention and education programs to prevent sexual violence in adolescence.

The purpose of this study was to test the theoretical model designed to explain juvenile delinquency by media violence. Data were collected through questionnaire survey over a period of 3 months. Subjects served for this study consisted of 537 adolescents including 217 delinquent adolescents and 320 student adolescents in Korea, sampled from Korean student population and delinquent adolescent population confined in juvenile correctional institutions, using proportional stratified random sampling method. In this study, exogeneous variable was family dynamic environment and endogeneous variables were character of adolescent including need satisfaction/ frustration, sociability, antisocial personality tendency, complaints of psychosomatic symptoms and depressive trend, juvenile delinquent behavior and media violence themes including the extent of interest in and exposure and modelling impulsiveness and modelling to media violence themes. A total of 18 instruments were used to operationalized concepts in this model. A validation study indicated that internal consistencies for the 18 instruments which the researcher used were reliable. The one month test-retest correlation for these instruments ranged from 0.54 to 0.88. Statistical methods employed were descriptive statistics and covariance structural modelling. In summarized conclusion, it was found that media violence served as the most contributor to juvenile delinquency by direct effect of 0.64(t=10.18). That is, as the adolescents have to be the higher extent of interest in and exposure and modelling impulsiveness and modelling to media violence themes, they will show the more frequency of delinquent behavior. The single most powerful contributor by total effect of 0.73(t=7.90) (direct effect=0.19, indirect effect=0.54) to the development of delinquent behavior identified in this study was a construct defining family dynamic environment. That is, as the adolescents had to be more unstable family dynamic environment, they became more frustrated to their psychological need, and revealed the more maladaptive personality pattern, consequently they behaved the higher misconducts such as juvenile delinquency through media violence.

PURPOSE: The purpose of this study was to determine the important factors on juvenile delinquency and to examine relationships between sex, age, the family environment, the personality of adolescents, smoking, and juvenile delinquency. Methods: Data collection was done through questionnaire surveys. The subjects for this study consisted of 1,948 adolescents delinquents : 784, students : 1,164 in Korea, using proportional stratified random sampling method. Statistical methods employed were chi-square, t-test and path analysis. Results: The results of this study were as follows : 1. The delinquent adolescents were reared in a more dysfunctional family environment, and had a higher maladaptive personality than the other student adolescents. 2. The delinquent adolescents showed the larger amount of smoking than the student adolescents. The cause of increased smoking tendency among delinquents simply were 'for social relation', 'for diversion', 'for nicotine addiction', whereas 'for tension relieving' among non-delinquent adolescents. 3. The most powerful contributors on delinquent behavior were antisocial personality tendencies, smoking, sex, strength of parent- child relationships, and the age of the adolescents in this order. Conclusions: Our cross-sectional findings indicate that smoking was one of the most powerful contributing variables to delinquent behavior, but family environment, personality, sex and age of adolescents were also proved to be strong exogenous variables to smoking in adolescents.

Criminology has been understood within a sociological framework until the emergence of neurocriminology, which describes, understands and predicts criminal behaviors from a neurobiological point of view. Not only using biological factors including genes and hormones to understand criminal behaviors, but also using neuroimaging techniques, the field of neurocriminology aims to delve into both structural and functional differences in the brain of individuals with aggression, antisocial personalities, and even the criminals. Various studies have been conducted based on this idea, however, there still are limitations for the knowledge from these studies to be used in the court. In this review article, we provide an overview of the various research in neurocriminology, and provide insight into the future direction and implication of the field.

OBJECTIVES: To investigate the epidemiological characteristics of antisocial personality disorder (ASPD) in young men in Chengdu and explore the characteristics and risks of violence. METHODS: Stratified random sampling was used to conduct a self-assessment questionnaire survey in 4 108 males aged from 18 to 34 in Chengdu, including general demographic characteristics, structured clinical interview for the diagnostic and statistical manual of mental disorders-Ⅳ axis Ⅱ disorders (SCID-Ⅱ) personality disorder screen questionnaire, violence questionnaire, psychosis screening questionnaire (PSQ), Alcohol Use Disorders Identification Test (AUDIT) and drug use. χ² test, univariate and multivariate logistic regression were used for analysis and odds ratio (OR) was calculated. RESULTS: The positive rate of ASPD was 5.91%, which was associated with young age, unmarried, unemployment state, low educational level, violent behavior, psychotic symptoms, alcohol and drug use (P<0.05). Young men with ASPD also had a risk (P<0.05) of violence (OR was 8.51), multiple violence (OR was 16.57), injury (OR was 6.68), intentional violence (OR was 11.41), etc., the risk decreased after controlling for psychotic symptoms and substance abuse, but was still statistically significant. CONCLUSIONS The risk of violence, severe violence and intentional violence in young men in Chengdu is high, and psychotic symptoms and substance abuse increase the risk of ASPD violence and relate characteristics.
