RESUMEN

Psychopathic traits have been associated with rearrest in adolescents involved in the criminal legal system. Much of the prior work has focused on White samples, short follow-up windows, and relatively low-risk youth. The current study aimed to evaluate the utility of the Hare Psychopathy Checklist: Youth Version (PCL:YV) for predicting general and violent felony recidivism in a large sample of high-risk, predominantly Hispanic/Latino, male adolescents (n = 254) with a five-year follow-up period. Results indicated higher PCL:YV scores and lower full-scale estimated IQ scores were significantly associated with a shorter time to felony and violent felony rearrest. These effects generalized to Hispanic/Latino adolescents (n = 193)-a group that faces disproportionate risk of being detained or committed to juvenile correctional facilities in the U.S. These results suggest that expert-rated measures of psychopathic traits and IQ are reliable predictors of subsequent felony and violent felony rearrest among high-risk male adolescents.

RESUMEN

OBJECTIVE: This survey study reports the substantial impact of the coronavirus disease (COVID-19) pandemic on the use and perceived advantages and disadvantages of telepsychology among forensic practitioners. HYPOTHESES: We hypothesized that telepsychology use among forensic practitioners would substantially increase during the pandemic. Additional exploratory research questions examined (a) changes in the frequency, type, nature, and motivation for use of telepsychology; (b) changes in impressions of advantages and disadvantages; and (c) barriers specific to the remote administration of assessment instruments in forensic evaluations. METHOD: We disseminated an online survey to one group of forensic practitioners (N = 128; 52% female, 89% White, Mage = 48 years) via various listservs approximately 4 months before COVID-19 shutdowns in the United States and to a second group of forensic practitioners (N = 156; 63% female, 90% White, Mage = 48 years) 1 year later (approximately 8 months after COVID-19 shutdowns began). RESULTS: Respondents used telepsychology at a significantly higher rate after the onset of COVID-19 (92%, n = 143) than before its onset (55%, n = 71). Nonusers of telepsychology before COVID-19 identified a number of perceived barriers to its use that were unsubstantiated by telepsychology users both before and during COVID-19 (e.g., rapport issues, confidentiality, and privacy issues). CONCLUSION: Self-reported use of telepsychology in forensic practice has nearly doubled since the pandemic began. Forensic practitioners will likely continue to use telepsychology, requiring research to address some of their remaining concerns. This includes research on the validity of forensic assessment instruments administered via telepsychology and research informing best practice guidelines.

RESUMEN

BACKGROUND AND OBJECTIVES: Drug courts provide an array of substance use treatments and community-based services for probationers struggling with substance use disorders. We assessed substance use treatment services utilization and related expenditures and relapse and recidivism outcomes and identified predictors of cost of provision of substance use treatment services in a matched cohort of Massachusetts probationers in drug courts and traditional courts. METHODS: This was an observational quasi-experimental study with 542 propensity-score-matched probationers initiating drug court between August 1, 2015 and February 28, 2018 and a minimum 6-month follow-up period. RESULTS: A significantly greater proportion of probationers in drug courts were female, self-reported opioids as their primary drug of choice, had a history of substance use treatment, and a high and very high risk of recidivism than their counterparts in traditional courts. We estimated that the provision of substance use treatment services was $1498 more expensive for probationers in drug courts than traditional courts (p = .054). There were no statistically significant differences in relapse or recidivism rates between court systems. DISCUSSION AND CONCLUSIONS: Probationer's age, gender, risk of recidivism at court intake, and enrollment length were strong predictors of expenditures on substance use treatment services. SCIENTIFIC SIGNIFICANCE: This was the first study to assess substance use treatment services utilization and outcomes among probationers in drug courts and traditional courts. Drug courts served the needs of probationers disproportionally impacted by nonserious drug-related offenses struggling with substance use disorders who were at a high and very high risk of recidivism at court intake.

RESUMEN

With a sample of 125 adults under community supervision (71.20% male, 76.00% White, mean age = 33.17 years), this study evaluated need-to-service matching using an evaluation framework from implementation science. Need-to-service matching is a case management strategy intended to align service referrals in case plans with justice-involved persons' criminogenic needs. The results indicated that need-to-service matching reached a high percentage of its target population at 81.70%. Within criminogenic need areas, good match frequencies ranged from 80.00% in family/marital problems to 98.29% in alcohol/drug problems. Clinical staff also met the adherence benchmark applied by the current study, which required a 75.00% match between individuals' criminogenic needs and the services they received. Justice-involved persons had, on average, 90.46% of their criminogenic needs matched with at least one service referral. Over-prescription of services (i.e., recommendation of services that were not needed) was high, with frequencies in need areas ranging from 60.98% in education/employment to 82.21% in antisocial patterns. Methods from implementation science are useful for structuring evaluations of need-to-service matching, understanding implementation success and failure, and generating recommendations for improving implementation practice. The field would benefit greatly from benchmarks for need-to-service matching evaluation elements.

RESUMEN

OBJECTIVE: Research indicates moderate-to-limited integration of the risk-need-responsivity (RNR) principles in probation case planning. Efforts to improve implementation are important targets for research, policy, and practice. This study examined the ability of two juvenile probation departments to implement RNR principles with fidelity following a comprehensive implementation protocol that included RNR-related policies, creation of a service matrix for criminogenic need-to-service matching, and extensive staff training. HYPOTHESES: The researchers anticipated fidelity to the risk and need principles would be stronger than previous studies. METHOD: This implementation study involved secondary data analysis of services received over 10 months for 254 adolescent offenders (76.80% male, 72.40% White, M age = 16.13 years) from two probation departments following adoption of the Youth Level of Service/Case Management Inventory. RESULTS: Probation departments evidenced strong fidelity to the risk principle, such that higher risk youth were assigned more services with higher intensity. Fidelity to the need principle was moderate at best (an average 24.61% to 29.38% need-to-service match) and varied by criminogenic need, overall risk level, and the operational definition of criminogenic need. CONCLUSIONS: Comprehensive implementation practices are associated with strong fidelity to the risk principle, but it may take longer for probation departments to achieve strong fidelity to the need principle. Researchers should identify more feasible methods for implementing the need principle and strive for a consensus on methods for measuring need-to-service match that are also consistent with probation policies.

RESUMEN

OBJECTIVES: Many agencies use risk assessment instruments to guide decisions about pretrial detention, postconviction incarceration, and release from custody. Although some policymakers believe that these tools might reduce overincarceration and recidivism rates, others are concerned that they may exacerbate racial and ethnic disparities in placements. The objective of this systematic review was to test these assertions. HYPOTHESES: It was hypothesized that the adoption of tools might slightly decrease incarceration rates, and that impact on disparities might vary by tool and context. METHOD: Published and unpublished studies were identified by searching 13 databases, reviewing reference lists, and contacting experts. In total, 22 studies met inclusion criteria; these studies included 1,444,499 adolescents and adults who were accused or convicted of a crime. Each study was coded by 2 independent raters using a data extraction form and a risk of bias tool. Results were aggregated using both a narrative approach and meta-analyses. RESULTS: The adoption of tools was associated with (a) small overall decreases in restrictive placements (aggregated odds ratio [OR] = 0.63, p < .001), particularly for individuals who were low risk and (b) small reductions in any recidivism (OR = 0.85, p = .020). However, after removing studies with a high risk of bias, the results were no longer significant. CONCLUSIONS: Although risk assessment tools might help to reduce restrictive placements, the strength of this evidence is low. Furthermore, because of a lack of research, it is unclear how tools impact racial and ethnic disparities in placements. As such, future research is needed.

RESUMEN

Youth with elevated psychopathic traits exhibit a number of comparable neurocognitive deficits as adult psychopathic offenders, including error-related processing deficits. Subregions of the basal ganglia play an important, though indirect, role in error-related processing through connections with cortical areas including the anterior cingulate cortex. A number of recent structural and functional magnetic resonance imaging (s/fMRI) studies have associated basal ganglia dysfunction in youth with elevated psychopathic traits, but these studies have not examined whether dysfunction occurring within subregions of the basal ganglia help contribute to error-related processing deficits previously observed in such at-risk youth. Here, we investigated error-related processing using a response inhibition Go/NoGo fMRI experimental paradigm in a large sample of incarcerated male adolescent offenders (n = 182). In the current report, psychopathy scores (measured via the Psychopathy Checklist: Youth Version (PCL:YV)) were negatively related to hemodynamic activity within input nuclei of the basal ganglia (i.e., the caudate and nucleus accumbens), as well as intrinsic/output nuclei (i.e., the globus pallidus and substantia nigra) and related nuclei (i.e., the subthalamic nucleus) during error-related processing. This is the first evidence to suggest that error-related dysfunction previously observed in youth with elevated psychopathic traits may be related to underlying abnormalities occurring within subregions of the basal ganglia.

RESUMEN

OBJECTIVE: There is increasing recognition in the justice system that transition-age youth (TAY) are in a unique developmental period that may require tailored policies and practices. This study investigated the differential predictive validity and potential for disparate impact of both juvenile (the Structured Assessment of Violence Risk for Youth and Youth Level of Service/Case Management Inventory) and adult risk assessment instruments (the Historical-Clinical-Risk Management-20 [HCR-20] and the Violence Risk Appraisal Guide [VRAG]) with this age group (ages 16-24), relative to adolescents (ages 12-15) or older adults (ages 25-40). METHOD: The authors obtained secondary data sets for the 4 instruments totaling 3,353 cases. The final samples for each instrument after exclusions ranged from 1,181 cases for the VRAG to 290 cases for the HCR-20. RESULTS: Age group generally did not moderate the prediction of any recidivism or of violent recidivism. The only exception was on the HCR-20, which significantly predicted recidivism regardless of age but operated better for TAY than adults. The VRAG was the only instrument with significant mean age-related differences in risk scores. CONCLUSIONS: The potential for an unfair impact of risk assessments on TAY is minimal regardless of whether they are processed in the juvenile or adult justice systems. This preliminary evidence suggests well-validated instruments used in either system should accurately quantify the likelihood of recidivism for TAY; however, this does not necessarily translate into effective risk management for this developmental period. More research using study designs developed specifically for examining age-related differences is needed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

RESUMEN

Adults with psychopathy have a high propensity for substance abuse, generally starting from a young age. This investigation tested hypotheses about differences in the neural responses associated with drug craving among high-risk young offenders with histories of abuse of stimulants and other drugs as a function of psychopathic traits. Fifty-four male adolescents (44 with a history of stimulant abuse and 10 controls) incarcerated at a maximum-security facility (M age = 17.08 years) completed a drug-cue exposure task while brain hemodynamic activity was monitored using functional magnetic resonance imaging (fMRI) with a mobile MRI scanner stationed at the facility. Psychopathic traits were assessed using the Hare Psychopathy Checklist: Youth Version (PCL:YV). In the stimulant abuser group, drug cues elicited activity in classic reward circuitry. Consistent with studies of adult psychopathic traits and substance abuse, there was a negative association between PCL-YV scores and hemodynamic response related to drug craving in the amygdala and ACC in youth with a history of stimulant abuse. However, there were considerably more negative associations between the PCL:YV and hemodynamic response among youth than adults and this was primarily due to callous-unemotional traits rather than interpersonal or behavioral traits. The implications for how personality traits modulate motivations for drug-seeking behavior among adolescent offenders are discussed.

RESUMEN

Disparate results have been found in previous reports when incorporating both interview-based and self-report measures of psychopathic traits within the same sample, suggesting such assessments should not be used interchangeably. We previously found Total and Facet 4 scores from Hare's Psychopathy Checklist: Youth Version (PCL:YV) were negatively related to amplitude of the error-related positivity (Pe) event-related potential (ERP) component. Here, we investigated using the same previously published sample whether scores on four different self-report measures of adolescent psychopathic traits (the Antisocial Process Screening Device [APSD], Child Psychopathy Scale [CPS], Inventory of Callous-Unemotional Traits [ICU], and Youth Psychopathic Traits Inventory [YPI]) were similarly associated with reduced Pe amplitude. Unlike our previous results, adolescent self-report psychopathy scores were not associated with reduced Pe amplitude in multiple regression analyses. Results obtained in the current report support previous research observing incongruent findings when incorporating different assessment types within the same sample.

RESUMEN

Risk assessment instruments are widely used by juvenile probation officers (JPOs) to make case management decisions; however, few studies have investigated whether these instruments maintain their predictive validity when completed by JPOs in the field. Moreover, the validity of these instruments for use with minority groups has been called into question. This field study examined the predictive validity of both the Structured Assessment of Violence Risk in Youth (SAVRY; n = 383) and the Youth Level of Service/Case Management Inventory (YLS/CMI; n = 359) for reoffending when completed by JPOs. The study also compared Black and White youth to examine the presence of test bias. The SAVRY and YLS/CMI significantly predicted reoffending at the test level, with most of the variance in reoffending accounted for by dynamic risk scales not static scales. The instruments did not differentially predict reoffending as a function of race but Black youth scored higher than White youth on the YLS/CMI scale related to official juvenile history. The implications for use of risk assessments in the field are discussed. (PsycINFO Database Record

RESUMEN

There is a strong movement toward juvenile justice agencies' use of risk assessment and risk-need-responsivity approaches to improve case management decisions for young offenders. However, little is known about whether adoption of risk assessment actually effectuates any changes in the way young offenders are handled. This was a multisite study of the impact on case processing of implementation of the Structured Assessment of Violence Risk in Youth (SAVRY) or Youth Level of Service/Case Management Inventory in 6 juvenile probation offices using a prepost design and 1,694 propensity score-matched young offenders. Consistent with the risk principle, there were significant changes to at least some areas of case processing in all but 1 site, most notably with respect to decreases in the amount of supervision youth received and in rates of out-of-home placement. The nature and extent of the impact varied as a function of sites' characteristics and implementation quality, not as a function of the risk assessment used. No increases in recidivism were observed in any site, and there was a significant reduction in recidivism in 1 site. The key benefits of implementation of valid risk assessment and case management procedures were improved resource allocation and fewer instances of inappropriate interference in youths' lives without an apparent increased risk to public safety.

RESUMEN

Adult psychopathic offenders show an increased propensity towards violence, impulsivity, and recidivism. A subsample of youth with elevated psychopathic traits represent a particularly severe subgroup characterized by extreme behavioral problems and comparable neurocognitive deficits as their adult counterparts, including perseveration deficits. Here, we investigate response-locked event-related potential (ERP) components (the error-related negativity [ERN/Ne] related to early error-monitoring processing and the error-related positivity [Pe] involved in later error-related processing) in a sample of incarcerated juvenile male offenders (n=100) who performed a response inhibition Go/NoGo task. Psychopathic traits were assessed using the Hare Psychopathy Checklist: Youth Version (PCL:YV). The ERN/Ne and Pe were analyzed with classic windowed ERP components and principal component analysis (PCA). Using linear regression analyses, PCL:YV scores were unrelated to the ERN/Ne, but were negatively related to Pe mean amplitude. Specifically, the PCL:YV Facet 4 subscale reflecting antisocial traits emerged as a significant predictor of reduced amplitude of a subcomponent underlying the Pe identified with PCA. This is the first evidence to suggest a negative relationship between adolescent psychopathy scores and Pe mean amplitude.

RESUMEN

Rearrest has been predicted by hemodynamic activity in the anterior cingulate cortex (ACC) during error-processing (Aharoni et al., 2013). Here, we evaluate the predictive power after adding an additional imaging modality in a subsample of 45 incarcerated males from Aharoni et al. (2013). Event-related potentials (ERPs) and hemodynamic activity were collected during a Go/NoGo response inhibition task. Neural measures of error-processing were obtained from the ACC and two ERP components, the error-related negativity (ERN/Ne) and the error positivity (Pe). Measures from the Pe and ACC differentiated individuals who were and were not subsequently rearrested. Cox regression, logistic regression, and support vector machine (SVM) neuroprediction models were calculated. Each of these models proved successful in predicting rearrest and SVM provided the strongest results. Multimodal neuroprediction SVM models with out of sample cross-validating accurately predicted rearrest (83.33%). Offenders with increased Pe amplitude and decreased ACC activation, suggesting abnormal error-processing, were at greatest risk of rearrest.

RESUMEN

This study used an item response theory (IRT) model and a large adolescent sample of justice involved youth (N = 1,007, 38% female) to examine the item functioning of the Psychopathy Checklist-Youth Version (PCL: YV). Items that were most discriminating (or most sensitive to changes) of the latent trait (thought to be psychopathy) among adolescents included "glibness/superficial charm," "lack of remorse," and "need for stimulation," whereas items that were least discriminating included "pathological lying," "failure to accept responsibility," and "lacks goals." The items "impulsivity" and "irresponsibility" were the most likely to be rated high among adolescents, whereas "parasitic lifestyle," and "glibness/superficial charm" were the most likely to be rated low. Evidence of differential item functioning (DIF) on 4 of the 13 items was found between boys and girls. "Failure to accept responsibility" and "impulsivity" were endorsed more frequently to describe adolescent girls than boys at similar levels of the latent trait, and vice versa for "grandiose sense of self-worth" and "lacks goals." The DIF findings suggest that 4 PCL: YV items function differently between boys and girls.

RESUMEN

A recently published study by the present authors reported evidence that functional changes in the anterior cingulate cortex within a sample of 96 criminal offenders who were engaged in a Go/No-Go impulse control task significantly predicted their rearrest following release from prison. In an extended analysis, we use discrimination and calibration techniques to test the accuracy of these predictions relative to more traditional models and their ability to generalize to new observations in both full and reduced models. Modest to strong discrimination and calibration accuracy were found, providing additional support for the utility of neurobiological measures in predicting rearrest.

RESUMEN

Recent neuroscientific evidence indicates that psychopathy is associated with abnormal function and structure in limbic and paralimbic areas. Psychopathy and substance use disorders are highly comorbid, but clinical experience suggests that psychopaths abuse drugs for different reasons than non-psychopaths, and that psychopaths do not typically experience withdrawal and craving upon becoming incarcerated. These neurobiological abnormalities may be related to psychopaths' different motivations for-and symptoms of-drug use. This study examined the modulatory effect of psychopathic traits on the neurobiological craving response to pictorial drug stimuli. Drug-related pictures and neutral pictures were presented and rated by participants while hemodynamic activity was monitored using functional magnetic resonance imaging. These data were collected at two correctional facilities in New Mexico using the Mind Research Network mobile magnetic resonance imaging system. The sample comprised 137 incarcerated adult males and females (93 females) with histories of substance dependence. The outcome of interest was the relation between psychopathy scores (using the Hare Psychopathy Checklist-Revised) and hemodynamic activity associated with viewing drug-related pictures vs. neutral pictures. There was a negative association between psychopathy scores and hemodynamic activity for viewing drug-related cues in the anterior cingulate, posterior cingulate, hippocampus, amygdala, caudate, globus pallidus, and parts of the prefrontal cortex. Psychopathic traits modulate the neurobiological craving response and suggest that individual differences are important for understanding and treating substance abuse.

RESUMEN

Identification of factors that predict recurrent antisocial behavior is integral to the social sciences, criminal justice procedures, and the effective treatment of high-risk individuals. Here we show that error-related brain activity elicited during performance of an inhibitory task prospectively predicted subsequent rearrest among adult offenders within 4 y of release (N = 96). The odds that an offender with relatively low anterior cingulate activity would be rearrested were approximately double that of an offender with high activity in this region, holding constant other observed risk factors. These results suggest a potential neurocognitive biomarker for persistent antisocial behavior.

RESUMEN

An effective approach to reducing recidivism is, first, to identify a youth's risk of reoffending and then to match the intensity of interventions to that risk level. This pre-post quasi-experimental, prospective study compared 247 (pre) with 217 (post) adjudicated youths to examine the implementation of the Structured Assessment of Violence Risk in Youth (SAVRY) and its effects on case management practices in Louisiana's Caddo parish probation office. The results indicated that placement rates dropped by 50%, use of maximum levels of supervision dropped by almost 30%, and use of community services decreased except for high-risk youths, but only after the SAVRY was properly implemented. This shift towards more appropriate allocation of resources that are matched to risk level occurred without a significant increase in reoffending. The implications for implementation and for use of risk/needs assessment in juvenile probation are discussed.
