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.

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.

OBJECTIVE: Externalizing disorders such as attention-deficit/hyperactivity disorder (ADHD), conduct disorder and antisocial personality disorder, as well as depression are common comorbidities in alcohol use disorder (AUD). The current study focused on the temporal relationship between the onsets of these disorders and AUD, and investigated the serial multiple mediator model of externalizing disorders (e.g., ADHD) and depression on AUD. METHODS: We analyzed the mediated effects of the Adult ADHD Self-Report Scale (ASRS), the Barratt Impulsiveness Scale motor (BIS_M) and the Beck Depression Inventory (BDI) on Korean version of the Alcohol Dependence Scale (ADS_K) using the multiple-step multiple mediation procedure regression analysis. In addition, we comparatively analyzed different clinical characteristics in relation to conduct problems. RESULTS: The multiple-step multiple mediation procedure found the serial multiple mediated effects of the BIS_M and the BDI on the relationship between the ASRS and the ADS_K. Also, the group with conduct problem was significantly high in ADHD symptoms, depression, anxiety, impulsivity, legal problems and alcohol-related problems, compared to the group without conduct problems. CONCLUSION: To sum up, the results of this study show that ADHD symptoms in childhood could exert significant effects on the severity of AUD in adulthood, and both disorders might be mediated by the externalizing disorders characterized by the core feature of motor impulsivity, and depression serially. Thus, the treatment of preceding disorders in accordance with developmental stages is an overarching clinical component for preventing the subsequent development of AUD and for its treatment.

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: 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.

Violence in individuals with schizophrenia and other psychotic disorders is known to be higher than in the general population, according to various definitions of violence, although most people with schizophrenia are not violent. Various factors are reported to increase the risk of violence: demographic characteristics such as male gender, young age, and low socioeconomic status; antisocial personality and history of conduct disorder; comorbidity of substance abuse; psychopathological-clinical variables including positive psychotic symptoms, duration of the untreated psychosis, and the first episode of psychosis; and cognitive disorders. There are 3 types of violent patients with schizophrenia: 1) violent patients with a history of conduct disorder prior to the onset of schizophrenia; 2) violent patients in an acute psychotic episode, with no history of conduct disorder prior to the onset of schizophrenia; and 3) chronically violent patients who show no aggressive behavior prior to their thirties and early forties, and then are engaged in serious violence often including homicide. There are some identified triggering factors including exposure to violence, traumatic brain injury, self-harm, unintentional injury, substance intoxication and parental bereavement. The preventive and treatment strategies will be discussed according to the two different pathways of violence that are classified by the history of conduct disorder. A scientific approach is essential to reduce the rates of violent behaviors and potentially related stigma in patients with schizophrenia.

Novelty seeking (NS) and antisocial personality (ASP) are commonly exhibited by those who suffer from addictions, such as substance abuse. NS has been suggested to be a fundamental aspect of ASP. To investigate the neurobiological substrate of NS and ASP, we tested the relationship between regional cerebral glucose metabolism and the level of NS, determining the differences between individuals with and without ASP. Seventy-two healthy adults (43 males, mean age±SD=38.8±16.6 years, range=20~70 years; 29 females, 44.2±20.1 years, range=19~72 years) underwent resting-state brain positron emission tomography (PET) 40 minutes after 18F-fluorodeoxyglucose (FDG) injection. Within 10 days of the FDG PET study, participants completed Cloninger's 240-item Temperament and Character Inventory (TCI) to determine NS scores. Participants with and without ASP were grouped according to their TCI profiles. Statistical parametric mapping analysis was performed using the FDG PET and TCI profile data. NS scores positively correlated with metabolism in the left anterior cingulate gyrus and the insula on both sides of the brain and negatively correlated with metabolism in the right pallidum and putamen. Participants with ASP showed differences in cerebral glucose metabolism across various cortical and subcortical regions, mainly in the frontal and prefrontal areas. These data demonstrate altered regional cerebral glucose metabolism in individuals with NS and ASP and inform our understanding of the neurobiological substrates of problematic behaviors and personality disorders.

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: Symptoms of attention-deficit hyperactivity disorder (ADHD) during childhood may persist into adulthood. This study included the development and validation process of the Korean Adult ADHD Rating Scale (K-AARS), which was developed for screening and monitoring treatment of adults with ADHD. METHODS: Preliminary questionnaires of the K-AARS were based on the reviews of previous adult ADHD scales and clinical experiences of the board certified child and adolescent psychiatrists in Korea. For this study, 136 adults (18-50 years old) with inattention, hyperactivity and/or impulsivity symptoms were enrolled as ADHD subjects, and compared with 406 control subjects (18-50 years old) without ADHD symptoms. Construct validity was examined using explorative factor analysis and Cronbach's alpha to obtain internal reliability coefficients. Concurrent validity was evaluated by comparison with the Conners' Adult ADHD Rating Scale (CAARS). RESULTS: An explorative factor analysis showed that the K-AARS had 8 factors (inattention, hyperactivity, impulsivity, antisocial personality disorder/conduct disorder/oppositional defiant disorder, impairment, driving, emotional dysregulation, disorganization). K-AARS was highly reliable in terms of internal consistency (Cronbach's alpha 0.77-0.95) and correlation between factors (0.57-0.86). Concurrent validity with the CAARS and discriminant validity were statistically significant. CONCLUSION: The K-AARS is a valid and reliable measure for assessment of Korean adults with ADHD.

OBJECTIVE: To investigate the structural abnormalities of brain in patients with antisocial personality disorder (ASPD) but without alcoholism and drug abuse. METHODS: Volunteers from Hunan Reformatory (n=36) and the matched healthy subjects (n=26) were examined by high-spatial resolution magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). Voxel-based morphometry and fractional anisotropy (FA) maps were generated for each subject to reveal structural abnormalities in patients with ASPD. RESULTS: Compared with the healthy controls, ASPD patients showed significantly higher gray matter volumes in the inferior parietal lobule (P≤0.001, uncorrected), white matter volumes in the precuneus (P≤0.001, uncorrected), FA in the left lingual gyrus, bilateral precuneus, right superior frontal gyrus and right middle temporal gyrus (P≤0.01, uncorrected). CONCLUSION Our results revealed the abnormal neuroanatomical features in ASPD patients, which might be related to the external behavioral traits in ASPD patients.
