DESCRIPTION

Callous-Unemotional Traits and Violent OffendingThe study examined whether callous-unemotional (CU) traits predict the onset of juvenile violent offending and the extent to which CU traits predict future violent offending. The analyses were based on 1,170 male adolescent offenders from the Pathways to Desistance project, a multisite, longitudinal study of serious juvenile offenders which begain in 2000, when project staff recruited 1,354 adolescents aged 14 through 18 who were adjudicated delinquent or found guilty of a serious (felony level) offense at their current court appearance in Philadelphia, PA (N = 654) and Phoenix, AZ (N = 700). Immediately after enrollment, researchers conducted a structured four-hour baseline interview with each adolescent. At each annual follow-up interview, researchers gathered information on the adolescents’ self-reported behavior and experiences during the prior 12 months. We restricted our current analyses to male adolescent offenders (N = 1,170), as the data set had only a marginally sufficient number of females in the sample (N = 184). Utilizing multinomial logistic regression, the present study found that adolescent males who were high in CU traits were more likely to commit a violent act before age 13, even after controlling for other known risk factors for violence. Additionally, odds ratios from the negative binomial regression analysis revealed that participants high in CU traits were nearly twice as likely than those with low or moderate CU traits to have committed more violent crimes at the 5-year follow-up. Implementing preventative interventions with children exhibiting early CU traits (prior to the onset of serious conduct problems) seems particularly important. If interventions can be better tailored to the unique characteristics (e.g., identifying CU traits) of children based on the developmental mechanisms underlying their conduct problems, more pronounced and sustained treatment effects will likely be achieved.

Paragraph 1Paragraph 2Paragraph 3Paragraph 4 (Problems with past research)Includes known covariates for violent offendingParagraph 5 (Summary)Paragraph 6 (Purpose)Research QuestionsAcknowledgementsTitle & AuthorsColumn TitleIntroduction SectionParagraph 1Researchers argue that callous-unemotional (CU) traits (i.e., general disregard for others, lacking empathy, shallow affect) delineate a subgroup of conduct-disordered youth that is more likely to engage in violent criminal behavior than conduct-disordered youth without such features (Flexon & Meldrum, 2013; Pardini & Frick, 2013).

Introduction SectionParagraph 2Previous studies have typically created groups of children based on extreme scores on scales that assess CU features and/or conduct-disorder symptoms. These studies tend to support the utility of CU traits for predicting violent and other antisocial behavior. However, the effect of CU is often not significant after controlling for initial differences between groups in antisocial behavior (Frick, Cornell, Bodin, Dane, Barry, & Loney, 2003). Introduction Section Paragraph 3In contrast, dimensional studies (i.e., studies that utilize continuous measures of CU traits and conduct disorder) suggest that CU features add modest predictive validity to impulsivity and past antisocial behavior (Pardini, Obradovi, & Loeber, 2006).

Introduction Section Paragraph 4However, previous research on juvenile psychopathy in general, and CU specifically, suffer from important methodological limitations, to include:inadequate sample sizes (Dyck, Campbell, Schmidt, & Wershler, 2013; Salekin, 2008; Edens & Cahill, 2007) retrospective designs or short follow-up durations (Edens & Cahill, 2007) failure to include other dimensions of psychopathic personality, such as impulsivity (Flexon & Meldrum, 2013) limited inclusion of additional risk factors for violent offending (Vaughn, Litschge, DeLisi, Beaver, & McMillen, 2008)

Introduction SectionParagraph 4 Continuedlimited inclusion of additional risk factors for violent offending (Vaughn, Litschge, DeLisi, Beaver, & McMillen, 2008)Environmental risk factors for violence:Peer deviance (i.e., number of friends arrested; see Baskin & Sommers, 2013)Family arrests (Dallaire & Wilson, 2010) Exposure to violence (both witnessing and victim of violence; see Baskin & Sommers, 2013)Poor neighborhood conditions (i.e., abandoned buildings, gang activity; Turner, Shattuck, Hamby, & Finkelhor, 2013)Individual risk factors for violence:Impulsivity (Castellanos-Ryan & Conrod, 2011)Anxiety (Dallaire & Wilson, 2010; Hammen, Brennan, Keenan-Miller, & Herr, 2008)Lack of psychosocial maturity/inability to regulate emotions (see Hammen et al., 2008)Low IQ (see Baskin & Sommers, 2013)Executive function impairments/lack of inhibitory control (see Pharo, Sim, Graham, Gross, & Hayne, 2011) Early onset problems (i.e., cheating, disturbing class, getting drunk/stoned, stealing, fighting; see Mulvey, 2004)School dropout (see Baskin & Sommers, 2013)Introduction SectionClosing Paragraphs 5 and 6Overall, these issues raise the need for additional research on the relationship between CU traits and violence, while controlling for potential covariates.

The present study aims to test these relationships by extending previous work examining CU traits, in addition to identifying the age of onset for CU traits and violent offending.Introduction SectionResearch QuestionsResearch Questions:Do CU traits predict the early onset of violent offending?Do CU traits predict future violent offending?

Negative binominal regression model was used to examine Time 1 predictors (i.e., baseline) of violent offending at Time 2 (i.e., 5-year follow-up). Initially we computed a conditional Poisson distribution model, but because the deviance statistic indicated overdispersion (when the true variance is bigger than the mean) we ultimately used negative binomial regression analyses for violent offending.

Materials and Methods SectionParagraph 3 (IV = CU Traits) Independent Variable: Callous-Unemotional Traits

CU was assessed with a 15-item, 4-point Likert subscale of the Youth Psychopathic Traits Inventory (Andershed et al., 2002; see Mulvey, 2004)Items ranged from does not apply at all to applies very well Examples of items indicating CU traits were: I usually feel calm when other people are scared, and I think that crying is a sign of weakness, even if no one sees you The baseline measure of CU (continuous scale) was used in the onset of violent offending analysisFor the 5-year follow-up regression model, a time-averaged (across 6 years) CU variable was computedSubjects were then categorized into three CU groups: Low CU (< mean)Moderate CU (mean - 1 std)High CU (> 1 std)

School Dropout(yes/no)Materials and Methods SectionParagraph 5 (DVs)Dependent Variables: Violent Offending and Age of Onset Self-reported violent offending. Modified version of the Self-Report of Offending scale (SRO; Elliott, 1990; see Mulvey, 2004) was used at each interview to measure the adolescents account of his involvement in one or more of eight violent crimes (gang activity fights, aggravated assault, carjacking, robbery with weapon, robbery without weapon, shooting someone, shooting at someone, carrying a gun). The dichotomized items were then summed together for the analyses. A sum of the number of types of violent offenses committed (a general versatility or variety score) was calculated for each subject at each interview.Age of onset for violent offending (at baseline). The age of onset for each of the eight violent offenses (mentioned above) were recorded during the baseline interviews. Utilizing the age of initiation data, a three-category variable was constructed: No violent offending Early onset (12 years old or younger) Later onset (13 years old to 18 years old)

PredictResults and Conclusion SectionAnswer to Question 11. Do CU traits predict the early onset of violent offending?

Adolescent males who were high in CU traits were more likely to commit a violent act before age 13, even when controlling for other known risk factors for violence (no violence v. early onset: odds ratio [OR] = .930, p < .001; later onset v. early onset: OR = .968, p < .05)Additional findings: Respondents who engaged in early onset violence (as compared to no violence) had lower levels of impulse control and executive functioning, a higher proportion of friends that were arrested, and lived in neighborhood with more physical and social problems

Results and Conclusion SectionAnswer to Question 22. Do CU traits predict future violent offending?

Respondents high in CU traits were almost twice as likely (OR = 1.79, p < .001) than those with low or moderate CU traits to have committed more types of violent crimes at the 5-year follow-up, even when controlling for individual differences.

Results and Conclusion SectionLimitations and Future DirectionsLimitations.The participants selected for this study did not include female adolescents. The study only included juveniles who had committed serious crimes and who were involved in the criminal justice system. The study did not include all types of violent crimes. Specifically, sexual assault and domestic violence were not among the eight types of violent crimes included in the measure of violent offending. Similarly, there was no distinction between instrumental versus reactive forms of violence. The study did not include substance use as a covariate, a risk factor that is highly correlated with violence.

Results and Conclusion SectionLimitations and Future DirectionsFuture directions. This study serves as a predictive utility of CU traits for violent outcomes.Intervening early in the developmental trajectory of childhood-onset behavioral problems represents an important avenue for preventing later serious aggression and antisocial behavior. Future research should continue to explore the pathways, trajectories and treatments for youth who exhibit early CU traits.
