Clarifying Conceptions Underlying Adult Psychopathy Measures: A Construct Validity Metric Approach.

Although the Psychopathy Checklist-Revised (PCL-R) and Psychopathic Personality Inventory (PPI) ostensibly measure the same construct, they seem to emphasize different conceptions of psychopathy. This study was designed to clarify these differences by testing how well the PCL-R and PPI map alternative conceptions of psychopathy. Construct validity metrics were used to compare patterns of associations between psychopathy measures and 14 theory-relevant criterion variables that were observed in a sample of 1,281 offenders-with patterns of associations that were predicted based on alternative psychopathy conceptions. PCL-R total scores were most consistent with Karpman's affective dysfunction-centered secondary conception, and PPI total scores were most consistent with the McCords' lovelessness-based conception. Although similarities emerged at the factor level, the PPI demonstrated higher levels of consistency between theory-based predictions and observed relations than did the PCL-R. These results provide direction for refining measures in future research and interpreting PCL-R and PPI scores in current practice.

How well do juvenile risk assessments measure factors to target in treatment? Examining construct validity.

There has been a surge of interest in using 1 type of risk assessment instrument to tailor treatment to juveniles to reduce recidivism. Unlike prediction-oriented instruments, these reduction-oriented instruments explicitly measure variable risk factors as "needs" to be addressed in treatment. There is little evidence, however, that the instruments accurately measure specific risk factors. Based on a sample of 237 serious juvenile offenders (Mage = 18, SD = 1.6), we tested whether California Youth Assessment Inventory (CA-YASI) scores validly assess the risk factors they purport to assess. Youth were assessed by practitioners with good interrater reliability on the CA-YASI, and by research staff on a battery of validated, multimethod criterion measures of target constructs. We meta-analytically tested whether each CA-YASI risk domain score (e.g., Attitudes) related more strongly to scores on convergent measures of theoretically similar constructs (e.g., criminal thinking styles) than to scores on discriminant measures of theoretically distinct constructs (e.g., intelligence, somatization, and pubertal status). CA-YASI risk domain scores with the strongest validity support were those that assess criminal history. The only variable CA-YASI risk domain score that correlated more strongly with convergent (Zr = .35) than discriminant (Zr = .07) measures was Substance Use. There was little support for the construct validity of the remaining 6 variable CA-YASI risk domains-including those that ostensibly assess strong risk factors (e.g., "Attitudes," "Social Influence"). Our findings emphasize the need to test the construct validity of reduction-oriented instruments-and refine instruments to precisely measure their targets so they can truly inform risk reduction.

Does staff see what experts see? Accuracy of front line staff in scoring juveniles' risk factors.

Although increasingly complex risk assessment tools are being marketed, little is known about "real world" practitioners' capacity to score them accurately. In this study, we assess the extent to which 78 staff members' scoring of juveniles on the California-Youth Assessment and Screening Instrument (CA-YASI; Orbis Partners, Inc., 2008) agree with experts' criterion scores for those cases. There are 3 key findings. First, at the total score level, practitioners manifest limited agreement (M ICC = .63) with the criterion: Only 59.0% of staff scores the tool with "good" accuracy. Second, at the subscale level, practitioners' accuracy is particularly weak for treatment-relevant factors that require substantial judgment-like procriminal attitudes (M ICC = .52)-but good for such straightforward factors as legal history (M ICC = .72). Third, practitioners' accuracy depended on their experience-relatively new staff's scores were more consistent with the criterion than those with greater years of experience. Results suggest that attention to parsimony (for tools) and meaningful training and monitoring (for staff) are necessary to realize the promise of risk assessment for informing risk reduction.

Probation Officer Role Emphases and Use of Risk Assessment Information before and after Training.

This research examined how probation officers use risk information about offenders, and how its use is affected by what aspects of their role they emphasize. Officers (N = 152) were invited to complete surveys before and after a risk assessment tool training (46.0-65.8% participation rate). Surveys assessed estimates of reoffense and officers' likely supervision approach given a probationer's risk level. Officers tended to overestimate the likelihood of medium- and high-risk offenders to reoffend. As risk level rose, officers tended to increase the number of meetings and referrals. Officers' role emphases were related to how they perceived low-risk offenders' likelihood to reoffend, but not for offenders at other risk levels. There was relative consistency in officers' role emphases, supervision decisions, and responses to violations, so that differences in practice did not appear to be systematic. Most officers' risk perceptions were more realistic after training. Copyright © 2016 John Wiley & Sons, Ltd.

Does the self-report Inventory of Callous-Unemotional Traits predict recidivism?

Callous-unemotional (CU) traits, that is, a lack of guilt or empathy and poverty of emotion, are believed to be the developmental precursor to psychopathy in adulthood, capturing its emotional detachment dimension. Similar to psychopathic adults, research shows that children and adolescents with high CU traits represent an important population at heightened risk for criminal behavior. The present study is the first to examine whether a self-report measure of CU traits, the Inventory of Callous-Unemotional Traits (ICU), predicts general and violent recidivism postinstitutional release among a sample of 227 juvenile justice-involved adolescent boys (M age = 15.73, SD = 1.27). Results indicated that boys high on CU traits were faster to reoffend postrelease both nonviolently (Hazard Ratio [HR] = 1.27, p < .01) and violently (HR = 1.54, p < .05). Further, the Uncaring subscale of the ICU predicted faster time to general recidivism (HR = 1.21, p < .05), whereas the Callousness subscale (i.e., "I do not care who I hurt to get what I want") predicted faster time to violent recidivism (HR = 1.39, p < .05). The present study provides preliminary support for the predictive validity of a brief, yet comprehensive self-report measure of CU traits. Findings inform youth risk assessment by offering possibilities within the domain of self-report for screening high-risk youth in need of intensive, comprehensive, and individualized intervention.

High-fidelity specialty mental health probation improves officer practices, treatment access, and rule compliance.

Many probation agencies in the United States assign offenders with mental illness to relatively small specialty caseloads supervised by officers with relevant training, rather than to large general caseloads. Specialty caseloads are designed to improve the process and outcomes of probation, largely by linking these probationers with psychiatric treatment and avoiding unnecessary violations. In this multimethod, longitudinal matched trial, we tested whether a prototypical specialty agency (n = 183) differed from a traditional agency (n = 176) in officers' practices, probationers' treatment access, and probationers' rule violations. The specialty agency yielded significantly (a) better officer practices (e.g., problem solving rather than sanction threats; higher quality relationships with probationers; more boundary spanning), (b) greater rates of treatment involvement, and (c) lower rates of violation reports than the traditional agency. Additionally, officers' use of sanctions and threats increased probationers' risk of incurring a probation violation, whereas high-quality officer-probationer relationships protected against this outcome. When implemented with fidelity, specialty mental health caseloads improved the supervision process for this high-need group.

Offenders with mental illness have criminogenic needs, too: toward recidivism reduction.

Many programs for offenders with mental illness (OMIs) seem to assume that serious mental illness directly causes criminal justice involvement. To help evaluate this assumption, we assessed a matched sample of 221 parolees with and without mental illness and then followed them for over 1 year to track recidivism. First, compared with their relatively healthy counterparts, OMIs were equally likely to be rearrested, but were more likely to return to prison custody. Second, beyond risk factors unique to mental illness (e.g., acute symptoms; operationalized with part of the Historical-Clinical-Risk Management-20; Webster, Douglas, Eaves, & Hart, 1997), OMIs also had significantly more general risk factors for recidivism (e.g., antisocial pattern; operationalized with the Level of Service/Case Management Inventory; Andrews, Bonta, & Wormith, 2004) than offenders without mental illness. Third, these general risk factors significantly predicted recidivism, with no incremental utility added by risk factors unique to mental illness. Implications for broadening the policy model to explicitly target general risk factors for recidivism such as antisocial traits are discussed.

Firm, fair, and caring officer-offender relationships protect against supervision failure.

A growing body of research suggests that high quality dual role relationships between community corrections officers and offenders reduce risk of recidivism. This study assesses whether this finding generalizes from offenders with mental illness to their relatively healthy counterparts. More importantly, this study tests the possibility that this finding is spurious, reflecting the influence of pre-existing offender characteristics more than a promising principle of practice. In this study of 109 parolees without mental illness, the authors found that (a) firm, fair, and caring relationships protect against rearrest, and (b) do so even after accounting for offenders' pre-existing personality traits and risk for recidivism. These findings are consistent with the theoretical notion that good dual role relationships are an essential element of core correctional practice, even (or particularly) for difficult or high risk offenders.

Do core interpersonal and affective traits of PCL-R psychopathy interact with antisocial behavior and disinhibition to predict violence?

The utility of psychopathy measures in predicting violence is largely explained by their assessment of social deviance (e.g., antisocial behavior; disinhibition). A key question is whether social deviance interacts with the core interpersonal-affective traits of psychopathy to predict violence. Do core psychopathic traits multiply the (already high) risk of violence among disinhibited individuals with a dense history of misbehavior? This meta-analysis of 32 effect sizes (N = 10,555) tested whether an interaction between the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 2003) Interpersonal-Affective and Social Deviance scales predicted violence beyond the simple additive effects of each scale. Results indicate that Social Deviance is more uniquely predictive of violence (d = .40) than Interpersonal-Affective traits (d = .11), and these two scales do not interact (d = .00) to increase power in predicting violence. In fact, Social Deviance alone would predict better than the Interpersonal-Affective scale and any interaction in 81% and 96% of studies, respectively. These findings have fundamental practical implications for risk assessment and theoretical implications for some conceptualizations of psychopathy.

Role of Serotonin and Dopamine System Interactions in the Neurobiology of Impulsive Aggression and its Comorbidity with other Clinical Disorders.

Impulsive aggression is characterized by an inability to regulate affect as well as aggressive impulses, and is highly comorbid with other mental disorders including depression, suicidal behavior, and substance abuse. In an effort to elucidate the neurobiological underpinnings of impulsive aggression and to help account for its connections with these other disorders, this paper reviews relevant biochemical, brain imaging, and genetic studies. The review suggests that dysfunctional interactions between serotonin and dopamine systems in the prefrontal cortex may be an important mechanism underlying the link between impulsive aggression and its comorbid disorders. Specifically, serotonin hypofunction may represent a biochemical trait that predisposes individuals to impulsive aggression, with dopamine hyperfunction contributing in an additive fashion to the serotonergic deficit. The current paper proposes a modified diathesis-stress model of impulsive aggression in which the underlying biological diathesis may be deficient serotonergic function in the ventral prefrontal cortex. This underlying disposition can be manifested behaviorally as impulsive aggression towards oneself and others, and as depression under precipitating life stressors. Substance abuse associated with impulsive aggression is understood in the context of dopamine dysregulation resulting from serotonergic deficiency. Also discussed are future research directions in the neurobiology of impulsive aggression and its comorbid disorders.

Psychometric Properties of Carver and White's (1994) BIS/BAS Scales in a Large Sample of Offenders.

Contemporary motivational theories of psychopathy (Lykken, 1995) employ constructs from Gray's Reinforcement Sensitivity Theory (RST; Gray, 1982), behavioral inhibition system (BIS) and behavioral activation system (BAS) functioning, to explain etiologic differences in psychopathy subtypes. Carver and White's (1994) BIS/BAS scales are the most widely used measures of these constructs, yet there is a dearth of research on how these measures perform with offenders. Using a sample of 1,515 offenders, we found evidence that five, rather than the usual four factors, underpin the BIS/BAS scales. Importantly, BIS items that tap into anxiety and fear sensitivity, respectively, split to form separate factors, yielding a structure that is more consistent with the revised (Gray & McNaughton, 2000) than with the earlier version of RST. Implications for the use of the BIS/BAS scales to study psychopathy in offenders are discussed.

Validity of factors of the Psychopathy Checklist--Revised in female prisoners: discriminant relations with antisocial behavior, substance abuse, and personality.

The validity of the Psychopathy Checklist-Revised (PCL-R) has been examined extensively in men, but its validity for women remains understudied. Specifically, the correlates of the general construct of psychopathy and its components as assessed by PCL-R total, factor, and facet scores have yet to be examined in depth. Based on previous research conducted with male offenders, a large female inmate sample was used to examine the patterns of relations between total, factor, and facet scores on the PCL-R and various criterion variables. These variables include ratings of psychopathy based on Cleckley's criteria, symptoms of antisocial personality disorder, and measures of substance use and abuse, criminal behavior, institutional misconduct, interpersonal aggression, normal range personality, intellectual functioning, and social background variables. Results were highly consistent with past findings in male samples and provide further evidence for the construct validity of the PCL-R two-factor and four-facet models across genders.
