RESUMO

OBJECTIVE: Despite advances in developing structured risk assessment instruments, there is currently no instrument to assess and manage the risk of intimate partner violence perpetration among adolescents. Given the empirical link between many forms of antisocial behavior, we tested whether structured tools commonly used by professionals to evaluate adolescents' risk of engaging in general violence and offending could be used to identify adolescents at risk for perpetrating intimate partner violence. HYPOTHESES: Because researchers have not yet examined whether risk assessment tools for general violence and offending predict intimate partner violence perpetration, we did not have a priori hypotheses regarding the predictive validity of these tools for this purpose. METHOD: Research assistants rated 156 adjudicated youth on the Structured Assessment of Violence Risk in Youth (SAVRY), Youth Level of Service/Case Management Inventory (YLS/CMI), and Psychopathy Checklist: Youth Version (PCL:YV) and recorded charges for intimate partner violence perpetration, any violent reoffending, and any reoffending over a 2-year follow-up period. RESULTS: Receiver operating characteristic analysis indicated that total scores and summary risk ratings on the SAVRY and YLS/CMI and total scores on the PCL:YV were significantly predictive of any violent reoffending and any reoffending, with moderate to large effect sizes, but were nonsignificantly associated with intimate partner violence perpetration. Further, penalized logistic regression analysis indicated that the SAVRY, YLS/CMI, and PCL:YV did not significantly add incremental validity to age, gender, race/ethnicity, and prior intimate partner violence perpetration and victimization for predicting future intimate partner violence perpetration. CONCLUSIONS: These findings suggest that the SAVRY, YLS/CMI, and PCL:YV could have limitations for assessing and managing intimate partner violence perpetration among adolescents.

RESUMO

Although many adolescent risk assessment tools include an emphasis on dynamic factors, little research has examined the extent to which these tools are capable of measuring change. In this article, we outline a framework to evaluate a tool's capacity to measure change. This framework includes the following: (a) measurement error and reliable change, and (b) sensitivity (i.e., internal, external, and relative sensitivity). We then used this framework to evaluate the Structured Assessment of Violence Risk in Youth (SAVRY) and Youth Level of Service/Case Management Inventory (YLS/CMI). Research assistants conducted 509 risk assessments with 146 adolescents on probation (101 male, 45 female), who were assessed every 3 months over a 1-year period. Internal sensitivity (i.e., change over time) was partially supported in that a modest proportion of youth showed reliable changes over the 3-, 6-, and 12-month follow-ups. External sensitivity (i.e., the association between change scores and reoffending) was also partially supported. In particular, 22% of the associations between change scores and any and violent reoffending were significant at a 6-month follow-up. However, only 1 change score (i.e., peer associations) remained significant after the Bonferroni correction was applied. Finally, relative sensitivity was not supported, as the SAVRY and YLS/CMI was not more dynamic than the Psychopathy Checklist: Youth Version (PCL:YV). Specifically, the 1-year rank-order stability coefficients for the SAVRY, YLS/CMI, and PCL:YV Total Scores were .78, .75, and .76, respectively. Although the SAVRY and YLS/CMI hold promise, further efforts may help to enhance sensitivity to short-term changes in risk. (PsycINFO Database Record

RESUMO

Although the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II) and the Structured Assessment of Violence Risk in Youth (SAVRY) include an emphasis on dynamic, or modifiable factors, there has been little research on dynamic changes on these tools. To help address this gap, we compared admission and discharge scores of 163 adolescents who attended a residential, cognitive-behavioral treatment program for sexual offending. Based on reliable change indices, one half of youth showed a reliable decrease on the J-SOAP-II Dynamic Risk Total Score and one third of youth showed a reliable decrease on the SAVRY Dynamic Risk Total Score. Contrary to expectations, decreases in risk factors and increases in protective factors did not predict reduced sexual, violent nonsexual, or any reoffending. In addition, no associations were found between scores on the Psychopathy Checklist:Youth Version and levels of change. Overall, the J-SOAP-II and the SAVRY hold promise in measuring change, but further research is needed.

RESUMO

BACKGROUND: Theories of procedural justice suggest that individuals who experience the criminal justice system as fair are more likely to perceive it as legitimate and, in turn, are less likely to reoffend. However, when individuals come into contact with the legal system, they are not blank slates - they have beliefs and personality characteristics that may systematically influence such perceptions. AIMS: Our aim was to establish the extent to which demographic characteristics, legal history and clinical features, including personality characteristics, systematically influenced the degree to which young people experience the justice system as fair and legitimate. METHOD: Self-report, file and interview data were collected from ninety-two 12 to 17-year-olds on probation in Western Canada. RESULTS: Substance use and traumatic experiences were inversely correlated with perceptions of procedural justice and legal legitimacy. Young people with higher scores on interpersonal, lifestyle and antisocial facets of the psychopathy checklist: youth version believed less strongly in the legitimacy of the law, but regression analyses confirmed that only history of trauma was independently associated with perceived procedural justice and legitimacy. Those in the youngest age group were more likely to have positive perceptions of justice than older youths, but demographics and legal history otherwise did not relate to outcomes. CONCLUSIONS: Our findings suggest that examining the relationship between procedural justice, legitimacy and offending without taking intra-individual variables into account may neglect important influences on those relationships. Other research has begun to show that young people who do not accept the law as legitimate or the criminal justice system as fair are more likely to offend. Copyright © 2016 John Wiley & Sons, Ltd.

RESUMO

Physical dating violence (PDV) victimization among adolescents is a serious global problem. Although knowledge of trends in PDV victimization can help guide programming and health policies, little research has examined whether the prevalence of PDV victimization has increased, decreased, or remained stable over time among non-U.S.-based samples of youth. In addition, few studies have directly tested whether disparities in PDV victimization between boys and girls have narrowed, widened, or remained unchanged in recent years. To address these gaps, we used school-based data from the British Columbia Adolescent Health Survey (BC AHS) of 2003, 2008, and 2013 (n boys = 18,441 and n girls = 17,459) to examine 10-year trends in PDV victimization. We also tested whether trends differed across self-reported sex. Data from the 2003 to 2013 BC AHS revealed that recent PDV victimization rates had significantly decreased among youth overall (5.9%-5.0%) and boys (8.0%-5.8%), but not girls (5.3%-4.2%). Although boys had steeper declines than girls in PDV victimization rates, year-by-sex interactions indicate that the sex gap in PDV victimization had not significantly narrowed. Moreover, rates of PDV victimization over the 10-year period indicated significantly higher rates of PDV victimization among boys compared with girls. Despite positive declines in recent rates of PDV victimization among youth, important differences in rates of PDV victimization between boys and girls remain. These findings underscore the need for greater attention to sex differences in research and programming and health policies to reduce PDV victimization and the sex disparities therein.

RESUMO

In this prospective study, we examined the association between three types of mental health symptom clusters (i.e., psychotic, internalizing, and externalizing) and the frequency and severity of violent-behavioral outcomes, and whether community disadvantage, residential instability, and criminogenic facility density moderated these associations. Study data were derived from 258 community-dwelling adults nested in 60 postal forward sortation areas (FSAs) in a large metropolitan area in Western Canada who were assessed twice over a 6-month period. In addition, census and administrative data were obtained on the same areas. Controlling for sociodemographic characteristics (i.e., age, gender, ethnicity, relationship status, and employment status), lifetime history of violent-behavioral outcomes, and community structural characteristics, internalizing and externalizing mental health symptoms were significantly positively associated with the frequency and severity of subsequent violence perpetration and with the severity of subsequent violent victimization. Several significant interactions were observed: internalizing symptoms increased the risk of frequent and severe violence perpetration in FSAs with high but not low disadvantage, and externalizing symptoms increased the risk of frequent violent victimization in FSAs with a high but not low criminogenic facility density. Only the interactive association of internalizing symptoms and community disadvantage with the severity of violence perpetration, however, remained significant after Bonferroni correction was applied. These findings provide tentative support that associations between mental health and violent-behavioral outcomes can vary with community context. The implication of these findings for assessing and managing violent-behavioral outcomes in the community is discussed.

RESUMO

Life satisfaction in adolescence has been shown to protect against numerous negative outcomes (e.g., substance use, sexual risk-taking), but limited work has directly explored the relationship between life satisfaction and youth violence and offending. As such, we conducted a prospective assessment to explore this relationship among community (n = 334) and at-risk youth (n = 99). Findings suggest life satisfaction is significantly associated with decreased offending and violence within both samples and adds incremental value above established risk factors in predicting violent and total offending among community youth. Furthermore, moderation analyses indicate that the protective value of life satisfaction is greater for youth with high callous-unemotional traits. Mediation analyses suggest that youth who are unsatisfied with their lives may seek out substance use, in turn elevating risk of offending. Together, these findings indicate that efforts to improve overall life satisfaction may help prevent adolescent offending. However, future research is needed.

RESUMO

Although the Structured Assessment of Violence Risk in Youth (SAVRY) and the Youth Level of Service/Case Management Inventory (YLS/CMI) are among the most widely used adolescent risk assessment tools, they conceptualize and measure strengths differently. As such, in this study, we compared the predictive validity of SAVRY Protective Total and YLS/CMI Strength Total, and tested conceptual models of how these measures operate (i.e., risk vs. protective effects, direct vs. buffering effects, causal models). Research assistants conducted 624 risk assessments with 156 youth on probation. They rated protective factors at baseline, and again at 3-, 6-, 9-, and 12-month follow-up periods. The SAVRY Protective Total and YLS/CMI Strength Total inversely predicted any charges in the subsequent 2 years (area under the curve scores = 0.61 and 0.60, respectively, p < .05). Furthermore, when adolescents' protective total scores increased, their self-reported violence decreased, thus providing evidence that these factors might play a causally relevant role in reducing violence. However, protective factors did not provide incremental validity over risk factors. In addition, because these measures are brief and use a dichotomous rating system, they primarily captured deficits in protective factors (i.e., low scores). This suggests a need for more comprehensive measures.

RESUMO

Small aliphatic esters are important natural flavor and fragrance compounds and have numerous uses as solvents and as chemical intermediates. Besides the chemical or lipase-catalyzed formation of esters from alcohols and organic acids, small volatile esters are made by several biochemical routes in microbes. This short review will cover the biosynthesis of esters from acyl-CoA and alcohol condensation, from oxidation of hemiacetals formed from aldehydes and alcohols, and from the insertion of oxygen adjacent to the carbonyl group in a straight chain or cyclic ketone by Baeyer-Villiger monooxygenases. The physiological role of the ester-forming reactions can allow degradation of ketones for use as a carbon source and may play a role in detoxification of aldehydes or recycling cofactors. The enzymes catalyzing each of these processes have been isolated and characterized, and a number of genes encoding the proteins from various microbes have been cloned and functionally expressed. The use of these ester-forming organisms or recombinant organisms expressing the appropriate genes as biocatalysts in biotechnology to make specific esters and chiral lactones has been studied in recent years.

RESUMO

Although experts recommend regularly reassessing adolescents' risk for violence, it is unclear whether reassessment improves predictions. Thus, in this prospective study, the authors tested 3 hypotheses as to why reassessment might improve predictions, namely the shelf-life, dynamic change, and familiarity hypotheses. Research assistants (RAs) rated youth on the Structured Assessment of Violence Risk in Youth (SAVRY) and the Youth Level of Service/Case Management Inventory (YLS/CMI) every 3 months over a 1-year period, conducting 624 risk assessments with 156 youth on probation. The authors then examined charges for violence and any offense over a 2-year follow-up period, and youths' self-reports of reoffending. Contrary to the shelf-life hypothesis, predictions did not decline or expire over time. Instead, time-dependent area under the curve scores remained consistent across the follow-up period. Contrary to the dynamic change hypothesis, changes in youth's risk total scores, compared to what is average for that youth, did not predict changes in reoffending. Finally, contrary to the familiarity hypothesis, reassessments were no more predictive than initial assessments, despite RAs' increased familiarity with youth. Before drawing conclusions, researchers should evaluate the extent to which youth receiving the usual probation services show meaningful short-term changes in risk and, if so, whether risk assessment tools are sensitive to these changes.

RESUMO

The Antisocial Process Screening Device (APSD) is a well-supported tool for assessing psychopathic features in youth. However, most research with the APSD has been derived from clinical and forensic samples comprised mainly of male Caucasian and African American adolescents. In this prospective study, the incremental and predictive validity of the self-report APSD for violent and non-violent offending was examined in an ethnically diverse community sample of male and female youth (N = 335) aged 12 to 14. High-school students from a moderate sized city in Western Canada completed the self-report APSD and then completed the Self-Report of Offending 6 months later. Receiver Operating Characteristics analysis indicated that APSD total and subscale scores were predictive of violent and non-violent offending at 6-month follow-up with moderate to large effect sizes. In addition, total scores on the APSD added incremental predictive utility above and beyond traditional criminogenic predictors of youth offending (i.e., prior offending, delinquent peer affiliation, poor school achievement, substance use, low parental monitoring). Although sex differences emerged in the predictive utility of the Impulsivity subscale of the APSD vis-à-vis violent offending, sex did not moderate the relationship between APSD total, Narcissism, or Callous/Unemotional scores and offending. In addition, the predictive utility of the APSD did not vary as a function of the youth's ethnic background. These findings suggest that: (1) the self-report APSD may have utility for risk or threat assessment with normative school populations, (2) APSD findings from higher risk samples generalize to a lower risk sample of high-school youth, and (3) predictive utility of APSD total scores do not differ across male and female Caucasian and ethnic minority youth.
