Jury Panel Member Perceptions of Interpersonal‐Affective Traits of Psychopathy Predict Support for Execution in a Capital Murder Trial Simulation

Recent research with college undergraduate mock jurors suggests that how psychopathic they perceive a criminal defendant to be is a powerful predictor of whether they will support a death verdict in simulated capital murder trials. Perceived affective and interpersonal traits of psychopathy are especially predictive of support for capital punishment, with perceived remorselessness explaining a disproportionate amount of variance in these attitudes. The present study attempted to extend these findings with a more representative sample of community members called for jury duty (N = 304). Jurors reviewed a case vignette based on an actual capital murder trial, provided sentencing verdicts, and rated the defendant on several characteristics historically associated with the construct of psychopathy. Consistent with prior findings, remorselessness predicted death verdicts, as did the affective and interpersonal features of psychopathy - though the latter effect was more pronounced among jurors who were Caucasian and/or who described their political beliefs as moderate rather than conservative or liberal. Results are discussed in terms of the potentially stigmatizing effects of psychopathy evidence in capital cases.

An exploration of criminal thinking styles among civil psychiatric patients.

BACKGROUND Several studies have found a relationship between psychiatric illness and criminal behaviour. Despite this, few studies have examined the presence of criminal thinking among civil psychiatric patients. AIMS The aim of this study is to explore the patterns and correlates of criminal thinking, using the Psychological Inventory of Criminal Thinking Styles (PICTS), in a sample of civil psychiatric patients. METHOD The PICTS (Layperson Edition) and the Brief Psychiatric Rating Scale (Anchored Version; BPRS) were administered to 76 civil psychiatric patients. PICTS scores were compared with those of offenders from a previously published study. Bivariate tests were conducted between selected PICTS scales, BPRS factors, demographic and criminal history variables. Stepwise multiple regressions were performed to assess those variables that predicted the general criminal thinking, proactive and reactive composite scales of the PICTS. RESULTS Independent samples t-tests revealed that five PICTS thinking styles were significantly higher in the psychiatric sample compared with the comparison sample of criminal offenders. Bivariate correlations revealed that the PICTS proactive composite scale was significantly related to and predicted by substance abuse and arrest history. CONCLUSIONS/CLINICAL IMPLICATIONS: Thinking styles which are typically associated with criminality were found in this sample of civil psychiatric patients. Cognitive remediation strategies targeting these may help to prevent criminal activity in psychiatric patients.

Using the Personality Assessment Inventory to predict male offenders' conduct during and progression through substance abuse treatment.

Prior research has supported the utility of the Personality Assessment Inventory (PAI; Morey, 1991, 2007) to predict various negative outcomes among offender samples, yet few studies have specifically examined its association with behavior in treatment. In this study, the PAI was administered to 331 male offenders court ordered into substance abuse treatment. Several theoretically relevant PAI scales (e.g., Antisocial Features, Borderline Features) predicted various forms of problematic conduct (e.g., disruptive behavior, aggression) and subjective and objective ratings of treatment progress. Although there was relatively limited evidence for the superiority of any one predictor over the others, the Aggression (AGG) scale demonstrated incremental validity above and beyond other indicators for general noncompliance and aggressive behavior. Interpersonal scales also predicted select treatment behavior while sharing relatively little common variance with AGG. These findings highlight the importance of distinguishing lower order and higher order dimensions on the PAI and other measures.

Predictive validity of the personality assessment inventory (PAI) for identifying criminal reoffending following completion of an in-jail addiction treatment program.

We examined the predictive validity of the personality assessment inventory (PAI; Morey, 2007) for criminal reoffending over a 44-60 month follow-up period among incarcerated offenders (N = 124) who completed an addiction treatment program. With this study, we sought to test whether PAI scores conceptually relevant to Andrews and Bontas (2010) central eight and responsiveness factors were predictive of general and specific reoffending in a sample with criminal involvement and substance-related impairment. PAI scores tapping antisocial personality style and the anger/hostile component of antisocial cognitions had the most robust relationships with the timing and occurrence of reoffending. Hostile dominance and discrepancy scores of observed versus predicted drug and alcohol problems were also predictive of reoffending. None of the other variables examined were consistently associated with reoffending. We discuss these results in relation to the use of the PAI to inform clinical decision making for individuals involved in the criminal justice system.

An Exploration of the Relationship Between Criminal Cognitions and Psychopathy in a Civil Psychiatric Sample

The relationship between psychopathy and thinking styles that support and maintain a criminal lifestyle is examined using the Psychopathy Checklist: Screening Version (PCL:SV; Hart, Cox, & Hare, 1995) and the Psychological Inventory of Criminal Thinking Styles (PICTS; Walters, 1995). These measures are administered to a sample of 75 patients recruited from a state psychiatric hospital in the northeastern United States. Correlational analyses indicate that the PICTS General Criminal Thinking, Self-Assertion/Deception factor scale, and several criminal thinking style scales are significantly related to psychopathy. The significantly associated criminal thinking scales include Entitlement (r = .44) and Superoptimism (r = .43) with Factors 1 and 2 of the PCL:SV, respectively. Multiple regression analyses reveal that these two criminal thinking scales are the strongest predictors of Factors 1 and 2 of the PCL:SV, respectively. Implications for the cognitive basis of the construct of psychopathy, as well as potential treatment interventions, are discussed.

The psychometric properties of the Personality Assessment Inventory–Adolescent’s Borderline Features Scale across two high-risk samples.

The present study sought to assess the performance of the Borderline Features (BOR) Scale of the adolescent version of the Personality Assessment Inventory (Morey, 2007b) in 2 high-risk samples: inpatient and justice-involved adolescents. This study is the first to evaluate the BOR scale in high-risk adolescent samples, outside the initial standardization studies. Across both samples (NClinical = 327, NForensic = 151), results indicated good internal consistency. Confirmatory factor analysis indicated poor fit of the 4-factor structure proposed by the measure’s authors. Convergent validity and receiver-operating characteristics analyses, conducted in the clinical sample, indicated that the adolescent version of the Personality Assessment Inventory BOR scale had good diagnostic accuracy for predicting a borderline personality disorder diagnosis (via structured interview). Findings suggest that the BOR scale has adequate internal consistency, convergent validity, and clinical utility, although areas for future measure evaluation (including factor structure) remain. Still, the BOR scale may partially address the current hesitation to assess borderline personality disorder features in high-risk youth because it is embedded within a broadband psychopathology measure.
