Ethnic differences in the relationship between psychopathy and (re)offending in a sample of juvenile delinquents

The present study focused on the relationship between psychopathy and delinquency in a multiethnic sample of juvenile offenders (N=207, n=105 native Dutch, and n=102 immigrants) referred to a treatment program. Aims were (1) to examine the cross-ethnic equivalence of the Antisocial Process Screening Device (APSD); (2) to compare the mean levels of psychopathic traits in native Dutch and immigrant juvenile delinquents and (3) the strength of the associations between psychopathic traits and delinquency in both the native Dutch and immigrant samples. Measurement invariance was established for APSD factors assessing callous-unemotional (CU) traits and impulsivity. However, there were ethnic differences in the factor structure of narcissism. No differences were found between ethnic groups in mean levels of CU traits and impulsivity. Finally, the association between impulsivity and self-reported delinquency was stronger for native Dutch than for immigrant juveniles. Further research is needed in order to make the treatment of juvenile delinquents with psychopathic traits in ethnic minority groups more effective according to the specific needs of these juveniles.     

Maltreatment and Family Dysfunction in Childhood and the Subsequent Adjustment of Children and Adults

The adjustment problems associated with sexual abuse, physical abuse, psychological maltreatment, neglect, and witnessing family violence during childhood were examined in three studies. Study 1 demonstrated significant overlap between maltreatment types in parent reports (N = 50) of maltreatment experiences of their child aged 5–12 years. Parental sexual punitiveness, traditionality, family adaptability and family cohesion significantly predicted scores on 4 maltreatment scales and children's externalizing behavior problems. Level of maltreatment predicted internalizing, externalizing, and sexual behavior problems. In Study 2, significant overlap was found between adults' retrospective reports (N = 138) of all 5 types of maltreating behaviors. Parental sexual punitiveness, traditionality, family adaptability, and family cohesion during childhood predicted the level of maltreatment and current psychopathology. Although child maltreatment scores predicted psychopathology, childhood family variables were better predictors of adjustment. Study 3 demonstrated that child maltreatment scores predicted positive aspects of adult adaptive functioning (N = 95).     

Impairment in the processing of fear gaze in adolescents with callous–unemotional traits

ABSTRACT

Callous and unemotional traits affect a subgroup of children and adolescents with severe conduct problems, characterized by lack of guilt, remorse, emotionality, and empathy, which trigger a chronic and severe antisocial pathway. One aim of the current study was to investigate if the results found by Dadds and his colleagues (Dadds et al., [2006]. Attention to the eyes and fear-recognition deficits in child psychopathy. British Journal of Psychiatry, 189, 280–281. doi:10.1192/bjp.bp.105.018150, [2008]. Reduced eye gaze explains ‘fear blindness’ in childhood psychopathic traits. Journal of the American Academy of Child & Adolescent Psychiatry, 47(4), 455–463. doi:10.1097/CHI.0b013e31816407f1) in the processing of the eye region of a fearful face in subjects with high levels of callous–unemotional traits could be replicated using event-related potentials (ERPs). From a sample of 48 male adolescent offenders, those who presented high CU (HCU) scores and low CU (LCU) scores were selected. Psychophysiological results show that HCU traits are associated with deficits in processing the eye region of fearful faces. These findings are discussed below.     

Assessing callous–unemotional traits in adolescent offenders: Validation of the Inventory of Callous–Unemotional Traits

The presence of callous–unemotional (CU) traits designates an important subgroup of antisocial youth. To improve upon existing measures, the Inventory of Callous–Unemotional Traits (ICU) was developed to provide an efficient, reliable, and valid assessment of CU traits in samples of youth. The current study tests the factor structure and correlates of the ICU scale in a sample (n = 248) of juvenile offenders (188 boys, 60 girls) between the ages of 12 and 20 (M = 15.47, SD = 1.37). Confirmatory factor analyses are consistent with the presence of three independent factors (i.e., Uncaring, Callousness, and Unemotional) that relate to a higher-order callous–unemotional dimension. Also, CU traits overall showed associations with aggression, delinquency, and both psychophysiological and self-report indices of emotional reactivity. There were some important differences across the three facets of the ICU in their associations with these key external criteria.     

Incarcerated youths with high or low callous–unemotional traits: a comparison controlling for age of crime onset

The aim of this study was to analyze the relevance of callous–unemotional (CU) traits in incarcerated juvenile delinquents. A sample of 160 incarcerated male youths was used. Results showed that youths with high CU traits had an earlier age of crime onset and of trouble with the law, and also had higher levels of conduct disorder. When controlling for age of crime onset, youths with high CU traits showed higher levels of general psychopathic traits and of psychopathy taxon membership as well as lower levels of prosocial behavior, but no differences were found for self-reported delinquency, crime seriousness, impulsivity-conduct problems, and general conduct problems. Also, no significant associations of CU traits with self-reported delinquency and crime seriousness were found when controlling for age of crime onset. Future studies of CU traits should take into account the specific importance of age of onset.     

Perceptions of police-juvenile contact predicts self-reported offending in adolescent males

ABSTRACT

Evidence suggests that positive experiences with the police can foster attitudes of respect towards the justice system that can reduce an adolescents’ propensity to commit later illegal behaviors. To advance prior work, we tested whether this association might be stronger for those adolescents who associate with deviant peers. Additionally, we tested whether the link between attitudes towards police and the justice system, and the influence of peer delinquency, would be weaker for those with elevated callous–unemotional (CU) traits. These predictions were examined in a prospective study using a sample (N?=?1,216) of adolescent males who were followed prospectively for 2 years following their first official contact with the juvenile justice system. Positive experiences with the police following the youth’s first arrest were associated with less self-reported delinquency 2 years later, which was partially mediated by reductions in adolescents’ cynicism about the legal system. However, this link was only significant for youth with low levels of peer delinquency. Although CU traits were related to less positive perceptions of experiences with the police and greater cynicism about the justice system, CU traits did not moderate the associations among experiences, attitudes, and later illegal behavior nor did they moderate the influence of peer delinquency.     

Postmortem Measurement of Human Chorionic Gonadotropin in Vitreous Humor and Bile

Abstract: Postmortem human chorionic gonadotrophin (HCG) blood assay can confirm postmortem diagnosis of pregnancy or document situations in which HCG levels are elevated. In some cases, however, blood sampling is not possible at autopsy. In this study, HCG was quantified by enzyme‐linked fluorescent assay (ELFA) in the bile (n = 5), vitreous humor (n = 4), and postmortem blood (n = 4) of five pregnant women. There were no false negatives in the pregnant subjects (n = 5) or false positives in controls (n = 34), enabling this test to be recommended for routine use in forensic contexts in which the detection of elevated HCG levels could be of interest.     

Social problem solving,anxiety, and depression in adult male prisoners

Objectives. Social problem‐solving ability has been identified as a significant mediator between stressful life‐events and psychological distress in community samples. This study examined the relationships between social problem solving, anxiety, and depression in adult male prisoners. The hypothesis was that a negative problem orientation (NPO) would be the strongest predictor of anxiety and depression. Methods. Participants (N=68) completed the Social Problem‐Solving Inventory–Revised: Short Version (SPSI‐R:S) and the Hospital Anxiety and Depression Scale (HADS). Results. NPO was found to be the sole predictor of anxiety and depression. Conclusion. NPO includes feelings of nervousness, threat, and fear in response to problems. In a prison setting, this may serve to protect the individual against conflict with and abuse by dominant others. However, high levels of fear and anxiety may be disabling both for coping with imprisonment and for effective participation in rehabilitation programmes. While this raises issues regarding prison cultures and the damage imprisonment may cause to individuals, it also indicates that interventions to assist some prisoners to cope are required.     

Recidivism and Psychiatric Symptom Outcomes in a Juvenile Mental Health Court

Few researchers have examined outcomes in Juvenile Mental Health Courts. Recidivism rates were assessed among 108 predominantly African American (95.3%) youth. Ages ranged from 12 to 18 (M = 15.85, SD = 1.45). Substantially fewer re‐convictions, along with re‐arrests, were exhibited among the treatment group (n = 54) compared to the control group (n = 54) after one year of participation or probation supervision. Psychiatric symptomatology among 21 youth was assessed pre‐ and post‐ intervention using the Comprehensive Behavior Rating Scales‐Self Report. Cohen's d effect sizes indicated substantial reductions in mental health symptoms (.33 ≥ d ≤ .88). Results are consistent with the previous studies of problem‐solving court efficacy.     

Morphoscopic Trait Expression in “Hispanic” Populations

This study evaluates population variation of eight cranial morphoscopic traits using samples of known southwest Hispanics (n = 72), Guatemalans (n = 106), American Blacks (n = 146), and American Whites (n = 218). We applied the support vector machine (SVM) method to build a prediction model based on a subsample (20%) of the data; the remainder of the data was used as a test sample. The SVM approach effectively differentiated between the four groups with correct classification rates between 72% (Guatemalan group) and 94% (American Black group). However, when the Guatemalan and southwest Hispanic samples were pooled, the same model correctly classified all groups with a higher degree of accuracy (American Black = 96%; American White = 77%; and the pooled Hispanic sample = 91%). This study also identified significant differences between the two Hispanic groups in six of the eight traits using univariate statistical tests. These results speak to the unique population histories of these samples and the current use of the term “Hispanic” within forensic anthropology. Finally, we argue that the SVM can be used as a classification model for ancestry estimation in a forensic context and as a diagnostic tool may broaden the application of morphoscopic trait data for the assessment of ancestry.     

Application of the Optimized Summed Scored Attributes Method to Sex Estimation in Asian Crania

The optimized summed scored attributes (OSSA) method was recently introduced and validated for nonmetric ancestry estimation between American Black and White individuals. The method proceeds by scoring, dichotomizing, and subsequently summing ordinal morphoscopic trait scores to maximize between‐group differences. This study tests the applicability of the OSSA method for sex estimation using five cranial traits given the methodological similarities between classifying sex and ancestry. A large sample of documented crania from Japan and Thailand (n = 744 males, 320 females) are used to develop a heuristically selected OSSA sectioning point of ≤1 separating males and females. This sectioning point is validated using a holdout sample of Japanese, Thai, and Filipino (n = 178 males, 82 females) individuals. The results indicate a general correct classification rate of 82% using all five traits, and 81% when excluding the mental eminence. Designating an OSSA score of 2 as indeterminate is recommended.     

Can Callous-Unemotional Traits and Aggression Identify Children at High-Risk of Anti-Social Behavior in a Low Socioeconomic Group?

Frick et al. (2005) proposed that Callous-Unemotional (CU) traits may be an important personality dimension associated with youth offending. The goal of the present study was to examine whether CU traits were associated with risk factors for offending in a low SES sample of children aged 10 years to 11 years in New Zealand. Two subgroups were identified: one high (High-CU/Agg group) and one low (Low-CU/Agg group) on CU traits and aggression. Results showed that scores for the High-CU/Agg group were significantly worse compared to the Low-CU/Agg group on a range of measures including stress management, caregiver criminal convictions, and dysfunctional parenting. However, analyses revealed that the measure of aggression accounted for more unique variance compared to CU traits. Further research is needed with youths from low SES communities to develop a more robust profile of potential youth offenders.     

The Ubiquitous Family Environment: Examining Emotional Insecurity in the Family and Adjustment in School

The present study examines adolescents' emotional insecurity and problem behaviors at school. Adolescents (n = 280; 136 boys, 144 girls, Median age = 13) and their parents reported on adolescents' emotional security and adjustment problems. Adolescents' teachers (n = 240) also reported on adolescents' school adjustment. Results support that emotional insecurity is related to adjustment problems in the home and at school. Emotional insecurity in the family system was a better predictor of adolescents' adjustment problems than emotional insecurity in the interparental relationship. Findings have implications for teachers, parents, school administrators and policy‐makers, as adolescents' problem behaviors at school can be explained by their emotional insecurity.     

Ancestry Assessment Using Random Forest Modeling, ,

A skeletal assessment of ancestry relies on morphoscopic traits and skeletal measurements. Using a sample of American Black (n = 38), American White (n = 39), and Southwest Hispanics (n = 72), the present study investigates whether these data provide similar biological information and combines both data types into a single classification using a random forest model (RFM). Our results indicate that both data types provide similar information concerning the relationships among population groups. Also, by combining both in an RFM, the correct allocation of ancestry for an unknown cranium increases. The distribution of cross‐validated grouped cases correctly classified using discriminant analyses and RFMs ranges between 75.4% (discriminant function analysis, morphoscopic data only) and 89.6% (RFM). Unlike the traditional, experience‐based approach using morphoscopic traits, the inclusion of both data types in a single analysis is a quantifiable approach accounting for more variation within and between groups, reducing misclassification rates, and capturing aspects of cranial shape, size, and morphology.     

Assessing Callous-Unemotional traits across different groups of youths: further cross-cultural validation of the Inventory of Callous-Unemotional traits

The Inventory of Callous-Unemotional (CU) Traits (ICU) is a self-report questionnaire which was developed to measure the affective features of psychopathy in children and adolescents. Previous studies reported both support and difficulties with this promising new measure. The present study investigated the psychometric and discriminating qualities of the Dutch questionnaire across different groups by examining its structure, distribution and correlates. The ICU was administered to young clinical offenders (detained, N=127), healthy controls (community, N=172), non-clinical offenders (not detained, N=42) and an externalizing non-offender group (under treatment for behavioral problems, N=42). The age range for all groups was 13-20years. Since confirmatory factor analysis of models from earlier research did not yield an acceptable fit, exploratory factor analysis was conducted. Five factors were extracted: Lack of Conscience, Uncaring, Unemotional, Callousness and Lack of Empathy. The results indicated moderate to good test-retest stability and adequate internal consistency. CU traits correlated well with measures of conduct problems and aggression, indicating a good criterion and convergent validity. Results indicate weak associations with expert (Psychopathy Checklist: Youth Version, PCL:YV) and informant (Antisocial Process Screening Device, APSD) measures of psychopathic traits. Although groups could be differentiated on a statistical basis, no meaningful distinction based on CU traits alone was possible. Results of this study cast doubt on the validity of the current ICU. Suggestions are made for improvement.     

Antidepressants at Autopsy in Hispanic Suicidal Youth in Miami‐Dade County,Florida*

Abstract: Controversy has surrounded the use of antidepressants and suicidal behaviors in youth. This study reviewed the Medical Examiner’s Office records of 253 persons aged 24 years or younger classified as suicides in Miami‐Dade County, Florida, from 1990 to 2007. Information was collected regarding demographic information, suicidal characteristics, psychiatric and psychosocial factors, and toxicology results. Eighty‐five percent of the sample was men, and 53.4% of the subjects were Hispanic. Consistent with previous literature, the existence of antidepressants at autopsy was rare; present in only 6% (n = 15) of the victims. The occurrence of antidepressants was not significantly different between Hispanics (n = 7) and non‐Hispanics (n = 8). The incidence of antidepressants was weakly correlated with a tendency to be men and no history of psychiatric illness. The presence of antidepressants in Hispanic youth suicide victims was similar to non‐Hispanics.     

The Etiology of Basal Vacuolizations in Renal Tubular Epithelial Cells Evaluated in an Isolated Perfused Kidney Model

To determine whether basal lipid vacuolization characteristic of ketoacidosis could be induced with short‐term hypertriglyceridemia, adult Sprague Dawley rat kidneys were perfused in an isolated perfused kidney model with, and without, 11.3 mM (10 g/L) of triglycerides in Krebs‐Henseleit buffer, for 1 and 2 h (n = 5/group). Additional treatments included perfusion with triglycerides with 20 mM of β‐hydroxybutyrate and 2 mM of acetoacetate (n = 5) and perfusion with triglycerides with 70 mM of glucose (n = 1). Basal vacuolization was produced in all groups, but differed in morphology to that reported in postmortem studies. There was no further increase in vacuolization after 2 h of perfusion compared to 1 h (p = 0.24), and the addition of ketones did not alter the morphology or extent of vacuolization. This study using an ex vivo model has confirmed that isolated hypertriglyceridemia is sufficient to cause basal lipid vacuolization in renal tubular epithelial cells, but with different morphology to vacuoles observed in lethal ketoacidosis at autopsy.     

Trait Anger,Physical Aggression,and Violent Offending in Antisocial and Borderline Personality Disorders

Antisocial personality disorder (ASPD) and borderline personality disorder (BPD) are common conditions in forensic settings that present high rates of violence. Personality traits related to the five‐factor model personality domains of neuroticism and agreeableness have shown a relationship with physical aggression in nonclinical and general psychiatric samples. The aim of the present investigation was to examine the association of these personality traits with violence and aggression in ASPD and BPD. Results revealed that trait anger/hostility predicted self‐reported physical aggression in 47 ASPD and BPD subjects (β = 0.5, p = 0.03) and number of violent convictions in a subsample of the ASPD participants (β = 0.2, p = 0.009). These preliminary results suggest that high anger and hostility are associated with physical aggression in BPD and ASPD. Application of validated, self‐report personality measures could provide useful and easily accessible information to supplement clinical risk assessment of violence in these conditions.
