Risk Assessments & Recidivism among a Population-Based Group of Swedish Offenders Sentenced to Life in Prison

BACKGROUND:
In Sweden, the number of people serving life sentences has steadily increased. To date, few studies have examined the recidivism rate or the predictive validity of different risk assessment instruments in this group.

AIMS:
Our aim was to test the predictive validity among inmates serving life sentences of two different instruments used for assessing risk-the Historical, Clinical and Risk Management-20 (HCR-20), most widely used in clinical populations, and the Psychopathy Checklist-Revised (PCL-R), commonly applied in both penal and clinical settings.

METHOD:
Ninety-eight life-sentenced prisoners were included, 26 of whom were released during the study period. Data on risk assessments and dates for release were collected from administrative records, while recidivism data were retrieved from a national database on criminal convictions.

RESULTS:
Sex offenders obtained the highest scores and inmates charged with domestic violent offences obtained the lowest scores on both instruments. The released prisoners were followed for a mean period of 33 months. During this time five prisoners (19%) reoffended, four of them violently, with an average time to recidivism of 10 months. Only PCL-R Facet 4, which reflects antisocial features, was significantly associated with recidivism.

CONCLUSIONS:
This small, but population-based, study demonstrates that antisocial behaviour shows incremental predictive validity for reoffending among life-sentenced offenders, but other measures have little to add for this specific task. The fact that those life sentenced prisoners who reoffended did so so soon after release should prompt allocation of earlier interventions towards preventing this.

Risk Factors for Intimate Partner Violence: A Comparison of Antisocial and Family-Only Perpetrators

Subtyping male perpetrators of intimate partner violence (IPV) based on their generality of violence could facilitate the difficult task of matching perpetrator subtype with efficient risk management strategies. 

As such, the aim of the present study was to compare antisocial and family-only male perpetrators of interpersonal violence in terms of 
  1. demographic and legal characteristics, 
  2. risk factors for violence, and 
  3. assessed risk and the importance of specific risk factors for violence. 
A quantitative design was used in this retrospective register study on data obtained from the Swedish police. Risk assessments performed with the Swedish version of the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER) and police registers were used. A sample of 657 male alleged IPV perpetrators were classified as antisocial (n= 341) or family-only (n= 316) based on their generality of violence. 

The results showed that the antisocial perpetrators were significantly younger, as well as more psychologically abusive. Antisocial perpetrators also had significantly more present risk factors for IPV, and were assessed with a significantly higher risk for acute and severe or deadly IPV, compared with the family-only perpetrators. The subtypes also evidenced unique risk factors with a significant impact on elevated risk for acute and severe or deadly such violence. Key findings in the present study concerned the subtypes evidencing unique risk factors increasing the risk for acute and severe or deadly IPV. 

Major implications of this study include the findings of such unique "red flag" risk factors for each subtype. To prevent future IPV, it is vital for the risk assessor to be aware of these red flags when making decisions about risk, as well as risk management strategies.

Genetic Background of Extreme Violent Behavior

In developed countries, the majority of all violent crime is committed by a small group of antisocial recidivistic offenders, but no genes have been shown to contribute to recidivistic violent offending or severe violent behavior, such as homicide. 

Our results, from two independent cohorts of Finnish prisoners, revealed that a monoamine oxidase A (MAOA) low-activity genotype (contributing to low dopamine turnover rate) as well as the CDH13 gene (coding for neuronal membrane adhesion protein) are associated with extremely violent behavior (at least 10 committed homicides, attempted homicides or batteries). No substantial signal was observed for either MAOA or CDH13 among non-violent offenders, indicating that findings were specific for violent offending, and not largely attributable to substance abuse or antisocial personality disorder. 

These results indicate both low monoamine metabolism and neuronal membrane dysfunction as plausible factors in the etiology of extreme criminal violent behavior, and imply that at least about 5–10% of all severe violent crime in Finland is attributable to the aforementioned MAOA and CDH13 genotypes.

Below:  Age- and gender-adjusted odds ratios for low-activity MAOA genotype and CDH13 (rs11649622) as a function of the number of committed violent crimes. The number of individuals, allele frequencies and odds ratios are shown below. The number of control subjects was 1946 for MAOA and 1877 for CDH13 analysis.

Like Parent Like Child? The Role of Delayed Childrearing in Breaking the Link Between Parent's Offending and Their Children's Antisocial Behavior

This paper investigates the impact of parents' history of violent offending, their age at first birth, and the interaction of the two on their adolescent children's violent behavior. We employ intergenerational longitudinal data from the Rochester Youth Development Study to estimate parental trajectories of offending from their early adolescence through early adulthood. We show that the particular shape of the parents' propensity of offending over time can interact with their age at first birth to protect their children from delinquency. We investigate these relationships for children at 6 and 10 years of age. We find that for some groups delaying childrearing can insulate children from their parents' offending.

Below:  Interquartile Ranges of Age at First Birth By Trajectory Group



...The more important research question is whether among those parents who put their children at risk by having participated in delinquent behavior, are there some relatively distal behaviors that can offset the effects of parental delinquency? That is, can even those parents who are in the high delinquent trajectory groups behave in ways that serve to protect their children from problematic behavior? Specifically, the question posed was whether having children later rather than earlier would serve to offset the effects of high parental involvement in delinquency.

The results answer the question affirmatively for those 10-year-old children of parents who were in the most delinquent trajectory group, the chronic group (group 5). The age of first birth is a protective factor for all three measures of problematic behavior for our 10-year-olds. Moreover, the impact of having parents who are in the group 5 is no longer significant once the interaction between age of first birth and group 5 membership is entered into the equation. It is important to note that this was not the case for the declining group (group 4). Their main effects of group membership on problematic behaviors were reduced to insignificance for two of the three outcomes when the interaction terms were entered into the equations. However, the interaction terms measuring the protective efficacy of delaying childbirth were not statistically significant. So, there is no protective effect of delaying childbirth. Although both group 4 and group 5 were similarly high in their offending patterns initially, the trajectory for group 4 sloped down while group 5 remained relatively high. In contrast, for group 4 (but not group 5) we found some evidence of a supportive effect for the protective role of age of first birth for the 6 year olds. The only significant impact of parental delinquency on the child’s problematic behavior was for the relationship between having parents in group 4 and the Achenbach delinquency scale. The interaction between age of first birth and parental membership in group 4 was significant as well, indicating that delaying having children protects children of relatively high risk parents even at the age of 6. The differences between 6- and 10-years-olds pose interesting questions about how mediators and protective factors might operate at different ages but we leave this for future research...

Early Life Risks, Antisocial Tendencies & Preteen Delinquency

Early age-of-onset delinquency and substance use confer a major risk for continued criminality, alcohol and drug abuse, and other serious difficulties throughout the life course. Our objective is to examine the developmental roots of preteen delinquency and substance use. 

Using nationally representative longitudinal data from the UK Millennium Cohort Study (n = 13,221), we examine the influence of early childhood developmental and family risks on latent pathways of antisocial tendencies from ages 3 to 7, and the influence of those pathways on property crime and substance use by age 11. We identified a normative, non-antisocial pathway; a pathway marked by oppositional behavior and fighting; a pathway marked by impulsivity and inattention; and a rare pathway characterized by a wide range of antisocial tendencies. 

Children with developmental and family risks that emerged by age 3-specifically difficult infant temperament, low cognitive ability, weak parental closeness, and disadvantaged family background-face increased odds of antisocial tendencies. There is minimal overlap between the risk factors for early antisocial tendencies and those for preteen delinquency. Children on an antisocial pathway are more likely to engage in preteen delinquency and substance use by age 11, even after accounting for early life risk factors.

The Availability and Utility of Services to Address Risk Factors for Recidivism among Justice-Involved Veterans

The availability and utility of services to address recidivism risk factors among justice-involved veterans is unknown. We explored these issues through qualitative interviews with 63 Specialists from the Department of Veterans Affairs’ (VA) Veterans Justice Programs. To guide the interviews, we utilized the Risk-Need-Responsivity (RNR) model of offender rehabilitation. Specialists reported that justice-involved veterans generally have access to services to address most RNR-based risk factors (substance abuse; lack of positive school/work involvement; family/marital dysfunction; lack of prosocial activities/interests), but have less access to services targeting risk factors of antisocial tendencies and associates and empirically-based treatments for recidivism in VA. Peer-based services, motivational interviewing/cognitive-behavioral therapy, and Veterans Treatment Courts were perceived as useful to address multiple risk factors. 

These findings highlight potential gaps in provision of evidence-based care to address recidivism among justice-involved veterans, as well as promising policy-based solutions that may have widespread impact on reducing recidivism in this population.

...The objectives of the current study were to determine the availability of services for justice-involved veterans that address empirically-supported risk factors for recidivism that are targeted by the RNR model, the types of treatment options and resources that are perceived as being most helpful in addressing these risk factors, and whether justice-involved veterans have access to empirically-based treatments for recidivism risk. For most risk factors (substance abuse, lack of positive school or work involvement, family/marital dysfunction, and lack of prosocial activities/interests), responses from the majority of Veterans Justice Program Specialists in our sample included description of some type of treatment option or resource that was available to address these issues among justice-involved veterans. By comparison, only a little more than half of the Specialists’ responses included description of any treatment options or resources to address antisocial tendencies and antisocial associates. This is noteworthy, given that risk factors related to antisociality (i.e., the Big Four) have been identified as the strongest predictors of criminal recidivism (, ).

The current findings are largely consistent with research on availability of services for offenders in general. For example, a recent review highlighted the range of offender reentry programs and services that target vocational training, substance abuse prevention, and other psychosocial needs of offenders (e.g., housing; James, 2015). By contrast, others have noted that extant programming for offenders tend not target antisocial tendencies, despite the centrality of these issues in the prediction of recidivism risk (;). This potential gap may be greater among justice-involved veterans, given that in the current study the availability of interventions that directly target antisocial cognitions and attitudes (e.g., MRT, T4C) were reported to be less prevalent in VA (vs. non-VA settings)...

Parent Programs for Reducing Adolescent’s Antisocial Behavior and Substance Use: A Randomized Controlled Trial

Two theoretically based parent training programs, delivered in real-world settings by the social services, were examined in this randomized controlled trial for effectiveness in reducing adolescents’ antisocial behavior and substance use. 

Two hundred and thirty-seven (237) adolescents in ages between 12 and 18 and their parents were assigned to one of two programs or to a wait-list control condition. The programs were the nine weekly group sessions program Comet 12–18 (Swedish Parent Management Training Program) and the six weekly ParentSteps (Swedish shortened version by Strengthening Families Program 10–14). Outcome measures were antisocial behavior, substance use, and delinquency, and psychosocial dysfunction. Data based on adolescents’ and parents’ ratings of the adolescents’ problem behavior at baseline and 6 months later were analyzed with repeated measures ANVOA, Logistic regression, and Kruskal–Wallis H test. 

The results showed that parents’ ratings of adolescents’ antisocial behaviors decreased significantly over time, but no time by group effect emerged. No program effects were found in the adolescents’ self-reported antisocial behavior, delinquency, or psychosocial functioning. A threefold risk of illicit drug use was found in both intervention groups. 

The results suggest that neither Comet nor ParentSteps had beneficial effects on adolescent’s antisocial or delinquent behavior, or on alcohol use. The only significant group difference found was a threefold risk of drug use in the intervention adolescents at follow-up, but for several reasons this finding should be interpreted with caution.

Impaired Executive Function in 14- to 16-Year-Old Boys with Conduct Disorder Is Related to Recidivism

BACKGROUND:
Several studies have suggested a relationship between cognitive impairment and recidivism, but most have adopted a retrospective design.

AIM:
The aim of this study was to test for any relationship between impaired executive function in adolescents with conduct disorder and subsequent recidivism up to 3 years later.

METHOD:
In this prospective cohort study, 221 male adolescents with conduct disorder, admitted to a juvenile justice assessment centre for the first time, were interviewed about their offence, age, onset of delinquency and family history. They completed the Wisconsin Card Sorting Test (Keio version) (KWCST) and the Iowa gambling task. Scores were compared between those who subsequently re-offended and those who did not.

RESULTS:
Seventy-six (34%) participants re-offended. There was no direct difference between groups in executive function, but there were age differences both in executive function and in recidivism. Multivariate logistic regression analysis indicated that the variables, which were independently associated with recidivism, were younger age, change in the person who brought up the child, and fewer (≤4) categories achieved on the KWCST. Recidivists were about twice as likely as single offenders to have achieved four categories or less on the KWCST (odds ratio 2.2, 95% confidence interval 1.1-4.4).

CONCLUSIONS:
Impaired executive function appears to predispose to recidivism among young first-time male offenders with conduct disorder. Our findings also suggest that further precise assessments of environmental stress on developing neurocognitive function could clarify the background of antisocial behaviour.

Empathy Impairments in Intimate Partner Violence Perpetrators with Antisocial and Borderline Traits: A Key Factor in the Risk of Recidivism

Antisocial, borderline, and narcissistic personality traits have been described as characteristics of intimate partner violence (IPV) perpetrators. Furthermore, deficits in cognitive empathy and impairments in emotional decoding processes may at least partially explain conduct disorders and social dysfunction in general. However, previous research has not explored potential associations between empathy deficits and the aforementioned traits or whether they are reflected in recidivism in IPV perpetrators. 

Accordingly, the main aim of this study was to explore associations between empathy deficits, antisocial, borderline, and narcissistic traits and the risk of recidivism in this population. 

The sample consisted of 144 IPV perpetrators (mean age = 41 years). High antisocial and borderline personality traits in this sample were associated with a high risk of recidivism, these relationships being moderated by poor empathy skills. Moreover, in IPV perpetrators with both antisocial and borderline personality traits, the risk of recidivism was higher than in those with only one of these traits. In contrast, narcissistic traits were unrelated to the risk of recidivism and impairments in empathy. 

The results of our study highlight the importance of empathy deficits and may help professionals to develop specific intervention programs focusing on improving empathy skills in antisocial and borderline IPV perpetrators.

Aggression Behavior & Substance Use among Immigrant Children: Mediating Effect of Antisocial Attitudes

In 2010, approximately one out of four youths in the United States were immigrant children. Hispanics and Asians comprised the largest groups (58% and 16%), respectively. Today, the Hispanic population is the largest ethnic minority in the United States (15%) and is a majority of the U.S. foreign-born population (47%). 

While immigration is a positive process for most immigrants, resettlement into a new country has challenges, including acculturation adjustments. Youth engage in risky behaviors such as substance use and antisocial behaviors. For immigrant youth with limited supportive opportunities, however, the acculturation process can be difficult. Stress, alienation, and stigma often manifest and cause behavioral problems, including aggression. 

This pilot study examines the mediating effect of antisocial attitudes using sociocultural, developmental, and environmental factors to understand Hispanic youth problem behaviors. We sampled 136 youths, ages 6-12, from predominantly Hispanic elementary schools in the southwestern United States to ascertain the role of aggression and antisocial behavior in substance use attitudes. 

The results show significant differences in aggression, antisocial attitudes, and substance use according to (1) age, (2) years in the United States, (3) English level, and (4) relationship with mother. Aggression significantly predicted antisocial attitudes and substance use, with antisocial attitudes having a mediating effect on the relationship between aggression and substance use. 

In developing social service programs to prevent substance use among children from immigrant families, social work educators and practitioners may consider addressing the role of aggression in Hispanic adolescents' future behavior.

Chronic Anger as a Precursor to Adult Antisocial Personality Features: The Moderating Influence of Cognitive Control

Anger is among the earliest occurring symptoms of mental health, yet we know little about its developmental course. Further, no studies have examined whether youth with persistent anger are at an increased risk of exhibiting antisocial personality features in adulthood, or how cognitive control abilities may protect these individuals from developing such maladaptive outcomes. 

Trajectories of anger were delineated among 503 boys using annual assessments from childhood to middle adolescence (ages 7-14). Associations between these trajectories and features of antisocial personality in young adulthood (age 28) were examined, including whether cognitive control moderates this association. 

Five trajectories of anger were identified (i.e., childhood-onset, childhood-limited, adolescent-onset, moderate, and low). Boys in the childhood-onset group exhibited the highest adulthood antisocial personality features (e.g., psychopathy, aggression, criminal charges). However, boys in this group were buffered from these problems if they had higher levels of cognitive control during adolescence. Findings were consistent across measures from multiple informants, replicated across distinct time periods, and remained when controlling for general intelligence and prior antisocial behavior. 

This is the first study to document the considerable heterogeneity in the developmental course of anger from childhood to adolescence. As hypothesized, good cognitive control abilities protected youth with persistent anger problems from developing antisocial personality features in adulthood. Clinical implications and future directions are discussed.
