The Inventory of Callous-Unemotional Traits (ICU) self-report version: Factor structure, measurement invariance, and predictive validity in justice-involved male adolescents.

The Inventory of Callous-Unemotional Traits (ICU) is a widely used measure of callous-unemotional (CU) traits that may aid in the assessment of the diagnostic specifier "with limited prosocial emotions," which has been added to diagnostic criteria for conduct disorder. Though there is substantial support for use of the ICU total score, the scale's factor structure has been highly debated. Inconsistencies in past factor analyses may be largely attributed to failure to control for method variance due to item wording (i.

Health Service Utilization in Adolescents Following a First Arrest: The Role of Antisocial Behavior, Callous-Unemotional Traits, and Juvenile Justice System Processing.

Previous research indicates that youth exhibiting antisocial behavior are at risk for utilizing a disproportionate amount of health services compared to youth without these problems. The present study investigates whether being processed by the juvenile justice system and showing callous-unemotional (CU) traits independently predict health service utilization (medical and mental health service use and out-of-home placement) over and above the severity of antisocial behavior across adolescence. A total of 766 participants who had been arrested for the first time in adolescence provided data at ten appointments over a period of seven years.

Improving the safety and effectiveness of urgent and emergency care.

Delays and waiting in urgent and emergency care (UEC) services are causing avoidable harm to patients and affecting staff morale. Patients are often having a poor experience of using UEC services, increasing stress and anxiety for both their families and themselves, delaying their recovery. Despite the constraints of available permanent staffing, funding and competing NHS priorities, changes along the whole UEC pathway in and out of hospital, admitted and non-admitted pathways need to be made safe, timely and accessible, to provide clinically appropriate care for patients.

Development and validation of a performance-based palliative care assessment tool for student pharmacists.

Introduction: Integration of hospice and palliative care principles within pharmacy curricula is essential to fill the need of pharmacist training in this growing specialty. A formalized assessment tool to evaluate skill development does not exist for student pharmacists specific to palliative care. The objective of this study was to develop a valid and reliable, palliative care-focused, performance-based assessment tool for student pharmacists.

Effects of neighborhood disadvantage and peer deviance on adolescent antisocial behavior: Testing potential interactions with age-of-onset.

Research has suggested that childhood-onset conduct problems (CPs) are more strongly related to individual predispositions, whereas adolescent-onset CP is more strongly associated with social factors, such as peer delinquency. Neighborhood disadvantage (ND) increases the risk for associating with deviant peers. Thus, peer delinquency could mediate the relationship between ND and adolescent-onset CP.

Aging Out of Crime and Personality Development: A Review of the Research Examining the Role of Impulsiveness on Offending in Middle and Late Adulthood.

Virtually everything we know about the relationship between impulsivity and offending is confined to adolescence and early adulthood. There is a paucity of research that examines impulsivity and offending in middle and late adulthood. What little is known is covered in this review.

Proactive and reactive aggression: Developmental trajectories and longitudinal associations with callous-unemotional traits, impulsivity, and internalizing emotions.

Research on proactive and reactive aggression has identified covariates unique to each function of aggression, but hypothesized correlates have often not been tested with consideration of developmental changes in or the overlap between the types of aggression. The present study examines the unique developmental trajectories of proactive and reactive aggression over adolescence and young adulthood and tests these trajectories' associations with key covariates: callous-unemotional (CU) traits, impulsivity, and internalizing emotions. In a sample of 1,211 justice-involved males (ages 15-22), quadratic growth models (i.

The bidirectional effects of antisocial behavior, anxiety, and trauma exposure: Implications for our understanding of the development of callous-unemotional traits.

The association of anxiety and trauma with antisocial behavior in children and adolescents has long been the focus of research, and more recently this area of research has become critical to theories of the development of callous-unemotional (CU) traits. Research suggests those with elevated CU traits and anxiety (i.e.

Inventory of Callous-Unemotional Traits (ICU) Factor Structure and Measurement Invariance in an Adolescent Multinational Sample.

Objective: The Inventory of Callous-Unemotional Traits (ICU) is a widely used, comprehensive measure of callous-unemotional (CU) traits. While the ICU total score is used frequently in research, the scale's factor structure remains highly debated. Inconsistencies in past factor structure research appear to be largely due to the use of small non-representative samples and failure to control for method variance (i.

Central-place foraging poses variable constraints year-round in a neotropical migrant.

Background: "Central-place foragers" are constrained in their habitat selection and foraging range by the frequency with which they need to return to a central place. For example, chick-rearing songbirds that must feed their offspring hourly might be expected to have smaller foraging ranges compared to non-breeding songbirds that return nightly to a roost.

Methods: We used GPS units to compare the foraging behaviour of an aerial insectivorous bird, the purple martin (Progne subis), during the breeding season in three regions across North America, as well as the non-breeding season in South America.

Longitudinal associations of parental monitoring and delinquent peer affiliation: The potential influence of parental solicitation and monitoring rules.

Introduction: Poor parental monitoring has been theorized as a key risk factor for an adolescent's association with deviant peers. However, measurements of parental monitoring often only measure parental knowledge rather than parental monitoring actions, leaving the true longitudinal associations between parental monitoring and peer delinquency unclear.

Methods: The current sample consisted of 1095 male justice-involved adolescents (13-17 years old at baseline collected between 2011 and 2013) from across the United States who provided survey data every 6 months for 3 years.

Examining Differences in the Effect of Vicarious and Personal Procedural Justice on Legal Orientations and Offending Across Race/Ethnicity Among a Sample of Serious Juvenile Offenders.

In the current study it is examined if the impact of vicarious and personal perceptions of procedural justice on legal cynicism, legitimacy, and offending across time is invariant across race/ethnicity. Using longitudinal data from a sample of serious juvenile offenders from the Pathways to Desistance, the within- and between-individual associations of procedural justice, legal orientations, and offending were tested. Race/ethnic-specific models were estimated to examine differences across race/ethnicity.

Differential Item Functioning of the Youth Psychopathic Traits Inventory Across Race/Ethnicity and Gender Among a Sample of Justice-Involved Youth: An Item Response Theory Analysis.

Research is yet to examine whether the items of the Youth Psychopathic Traits Inventory (YPI) function equally well across race/ethnicity and gender. The current study applies an item response theory analysis to detect differential item functioning (DIF) of the YPI subscale across White, Black, and Hispanic youth and males and females among a sample of justice-involved youth. Significant DIF was detected for several items between Black youth and White youth and Black youth and Hispanic youth.

The associations of maternal warmth and hostility with prosocial and antisocial outcomes in justice-involved adolescents.

Parental warmth and hostility are two key dimensions of parenting for child development, but the differential effects of these parenting dimensions on child prosocial and antisocial development has not been adequately investigated. The current study hypothesized that parental warmth would be uniquely related to child callous-unemotional traits and prosocial behavior, whereas parental hostility would be uniquely related to child delinquency and aggression. These hypotheses were investigated in a diverse sample of 1,216 adolescent males (13 to 17 years old, 46% Latino, 37% Black) with justice-system involvement in the 5 years following their first arrest.

Developing Cutoff Scores for the Inventory of Callous-Unemotional Traits (ICU) in Justice-Involved and Community Samples.

The recent addition of the callous-unemotional (CU) traits specifier, "with Limited Prosocial Emotions (LPE)," to major classification systems has prompted the need for assessment tools that aid in the identification of elevations on these traits for diagnostic purposes. The goal of the current study was to use and evaluate multiple methods for establishing cutoff scores for the multi-informant questionnaire, the Inventory of Callous-Unemotional Traits (ICU). The present study compared the clinical utility of various proposed cutoff methods and scores (i.

The use of nocturnal flights for barrier crossing in a diurnally migrating songbird.

Background: The migration patterns of land birds can generally be divided into those species that migrate principally during the day and those that migrate during the night. Some species may show individual plasticity in the use of day or night flight, particularly when crossing large, open-water or desert barriers. However, individual plasticity in circadian patterns of migratory flights in diurnally migrating songbirds has never been investigated.

The utility of self-reported psychopathic traits in predicting recidivism among a sample of incarcerated female youths.

Only a few studies have prospectively examined the utility of self-reported measures of psychopathic traits in predicting criminal behavior among forensic samples of female youth offenders. The main aim of this study is to compare the utility of two self-report measures of psychopathic-like traits in predicting criminal recidivism among a sample of incarcerated female youths. Participants (N = 76) from the three nation-wide Portuguese juvenile detention centers that admit female youths were followed over two years and prospectively classified as recidivists versus non-recidivists.

Callous-Unemotional Traits and Risk of Gun Carrying and Use During Crime.

Objective: With the addition of the "with limited prosocial emotions" specifier within the diagnosis of conduct disorder (DSM-5) and of conduct-dissocial disorder (ICD-11) to designate those with elevated callous-unemotional traits, the authors examined the role that callous-unemotional traits play in the risk for gun carrying and gun use during a crime in a sample at high risk for gun violence.

Methods: Male juvenile offenders (N=1,215) from three regions of the United States were assessed after their first arrest and then reassessed every 6 months for 36 months and again at 48 months. Callous-unemotional traits and peer gun carrying and ownership were measured via self-report after the first arrest (i.

A Longitudinal Test of the Mediational Role of Delinquent Peer Association on the Link Between Psychopathy and Offending.

Although prior research has found that psychopathy and delinquent peer association are predictors of delinquency, less research has assessed the dynamic role of peers in the relationship between psychopathic traits and offending. Using 10 waves of data from the Pathways to Desistance longitudinal study ( = 1,354), the current exploratory study investigates the impact of changes in delinquent peer association on the relationship between psychopathy and self-reported offending. Although the effects are small, results indicate that youth with higher Psychopathy Checklist Youth Version (PCL:YV; Forth et al.

Do callous-unemotional traits moderate the effects of the juvenile justice system on later offending behavior?

Background: Research suggests that callous-unemotional (CU) traits, a recent addition to psychiatric classification of serious conduct problems, may moderate the influence of a number of contextual factors (e.g., parenting, deviant peer influence) on an adolescent's adjustment.

Does self-report of aggression after first arrest predict future offending and do the forms and functions of aggression matter?

The current study tested whether a self-report measure of aggression (i.e., the Peer Conflict Scale; PCS) would predict later delinquency, after controlling for other risk factors, and tested whether the different forms and functions of aggression contributed independently to this prediction.

A Prospective Study on Self-Reported Psychopathy and Criminal Recidivism Among Incarcerated Male Juvenile Offenders.

The present study examines the utility of three self-report measures of psychopathic traits in predicting recidivism among a sample of incarcerated male juvenile offenders. Participants ( = 214, = 16.40 years, = 1.

Estimating and predicting the course of callous-unemotional traits in first-time adolescent offenders.

The stability of callous-unemotional (CU) traits and both individual and contextual factors that influence this stability have been studied in community adolescent samples but not to great extent in adolescents who have been arrested. We estimated the developmental changes in CU traits measured over the course of 36 months (6-month intervals) following the first arrest of male adolescents ( = 1,216). Using latent growth curve modeling and the multiple cohort multiple group method to account for the accelerated cohort study design, we were able to estimate the degree of change in these traits from ages 13 to 20 years.
