Predictive validity of the SAVRY, YLS/CMI, and PCL:YV is poor for intimate partner violence perpetration among adolescent offenders.

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.

Do Community Structural Characteristics Moderate the Association Between Mental Health and the Frequency and Severity of Violent-Behavioral Outcomes in Community Respondents?

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.

The Role of Life Satisfaction in Predicting Youth Violence and Offending: A Prospective Examination.

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.

Ten-Year Trends in Physical Dating Violence Victimization Among Adolescent Boys and Girls in British Columbia, Canada.

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.

Assessing Protective Factors for Adolescent Offending: A Conceptually Informed Examination of the SAVRY and YLS/CMI.

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.

Are adolescent risk assessment tools sensitive to change? A framework and examination of the SAVRY and the YLS/CMI.

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.

Does reassessment of risk improve predictions? A framework and examination of the SAVRY and YLS/CMI.

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.

Questioning fairness: the relationship of mental health and psychopathic characteristics with young offenders' perceptions of procedural justice and legitimacy.

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.

Incremental and Predictive Validity of the Antisocial Process Screening Device in a Community Sample of Male and Female Ethnic Minority and Caucasian Youth.

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.

Changes in J-SOAP-II and SAVRY Scores Over the Course of Residential, Cognitive-Behavioral Treatment for Adolescent Sexual Offending.

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.

Microbial formation of esters.

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.
