Demographic, criminogenic, and psychiatric factors that predict competency restoration.

Previous research has investigated the characteristics of competent and incompetent defendants and restorable and nonrestorable defendants. However, less is known about the influence of current treatment variables and other systemic factors on restorability. In the present study, we sought to examine the impact of demographic, criminogenic, historical clinical, and current treatment variables on the restorability and length of stay (LOS) of incompetent defendants. We reviewed the records of 71 male patients who had been court ordered for competency restoration and subsequently discharged from a maximum-security forensic hospital. Results indicated that nonrestorable patients had more prior hospitalizations, incarcerations, and episodes of incompetence, had lower level charges, were diagnosed with a psychotic and cognitive disorder, were prescribed more medications, and had lower global assessment of functioning (GAF) scores. Nonrestorable patients were hospitalized nearly twice as long as those eventually found competent, and patients with lower IQs and lower GAFs and who spent more days on special observations had longer LOS.

Police officers' experience with trauma.

This study examined officers' perceptions of the traumatic events they encounter on the job. Officers (N = 313) completed a survey asking about their experience with specific types of trauma, as well as what they considered to be their most traumatic event. They were given the opportunity to describe their unique perceptions of these events in response to open-ended questions. The results revealed vast variability in officers' experience with trauma in terms of the number, type, unique perceptions, and impact of these events. Results are discussed in terms of their implications for clinicians who treat officers affected with posttraumatic stress reactions and disorders.

Police interviewing and interrogation: a self-report survey of police practices and beliefs.

By questionnaire, 631 police investigators reported on their interrogation beliefs and practices-the first such survey ever conducted. Overall, participants estimated that they were 77% accurate at truth and lie detection, that 81% of suspects waive Miranda rights, that the mean length of interrogation is 1.6 hours, and that they elicit self-incriminating statements from 68% of suspects, 4.78% from innocents. Overall, 81% felt that interrogations should be recorded. As for self-reported usage of various interrogation tactics, the most common were to physically isolate suspects, identify contradictions in suspects' accounts, establish rapport, confront suspects with evidence of their guilt, and appeal to self-interests. Results were discussed for their consistency with prior research, policy implications, and methodological shortcomings.

Opinion formation in evaluating the adjudicative competence and restorability of criminal defendants: a review of 8,000 evaluations.

Evaluations of competence to stand trial (CST) are the most common type of criminal forensic evaluation conducted, and courts tend to defer to clinician opinions regarding a defendant's competence. Thus, it is important to study the ways in which clinicians arrive at opinions regarding adjudicative competence and the data they consider in forming their opinions. We reviewed 8,416 evaluations conducted by forensic evaluators in Virginia over a 12 year period, and examined (a) the clinical, demographic, and criminal characteristics of a defendant as related to opinions regarding competence, predicted restorability, and impairment on "prongs" of the Dusky standard, (b) process and outcome differences in evaluations conducted by psychiatrists versus psychologists and inpatient versus outpatient evaluators, and (c) the consistency of incompetence base rates over a 10 year period. Overall, clinicians opined that 19% of defendants were incompetent and considered 23% of these unlikely to be restored to competence. Not surprisingly, psychotic and organic/intellectual disorders were most strongly associated with findings of incompetence. However, there were some notable differences between evaluations by psychologists versus psychiatrists and between evaluations conducted in inpatient versus outpatient settings.

The impact of mental health evidence on support for capital punishment: are defendants labeled psychopathic considered more deserving of death?

Controversy surrounds the use of the Hare Psychopathy Checklist--Revised (Hare, 1991, 2003) in capital murder cases, where it has been introduced to support prosecution claims that a defendant represents a "continuing threat to society". Although widely presumed to have a prejudicial impact (e.g., American Psychological Association, 2004), little is known about how the lay public reacts to data derived from ostensibly stigmatizing assessment instruments such as the PCL-R. The present study examined the effect of psychopathy data on layperson attitudes by having 203 undergraduates review a capital murder case where the results of the defendant's psychological evaluation were experimentally manipulated. When expert testimony described the defendant as psychopathic, a much larger percentage of participants supported a death sentence (60%) than when testimony indicated that he was psychotic (30%) or not mentally disordered (38%). Interestingly, participant ratings of how psychopathic they perceived the defendant to be--regardless of the testimony condition to which they had been assigned--also predicted support for a death sentence. Given the limited probative value of the PCL-R in capital cases and the prejudicial nature of the effects noted in this study, we recommend that forensic examiners avoid using it in these trials.

The influence of psychosocial maturity on male juvenile offenders' comprehension and understanding of the Miranda warning.

Self-report measures of psychosocial maturity and screening measures of achievement and intelligence (Wechsler Abbreviated Scale of Intelligence; WASI) were used to investigate the influence of psychosocial maturity on male juvenile offenders' comprehension and appreciation of the Miranda warning (Grisso's Instruments for Assessing Understanding and Appreciation of Miranda Rights; GUAM). A sample of 67 male juvenile offenders, placed in a short-term detention facility or juvenile boot camp facility, participated in the study. Demographic differences revealed that youths in short-term detention were approximately one year older than boot camp youths. The two groups did not differ in IQ or measures of psychosocial maturity. Detention youths had GUAM subtest scores that were slightly higher than, but comparable to, those of boot camp youths. Consistent with previous research, verbal IQ correlated positively with GUAM subtest scores and was a significant predictor of all four scores after controlling for setting and age in a series of hierarchical regressions. In addition, the psychosocial maturity factor of Responsibility was a significant predictor of two GUAM subtests (CMR and FRI), while the Temperance and Perspective factors were not.

Are there ethnic differences in levels of psychopathy? A meta-analysis.

Although considerable research on psychopathy has been conducted over the past 30 years, relatively few studies have examined key issues related to potential ethnic differences in this constellation of socially maladaptive personality traits. Given recent sociopolitical and scientific developments, an issue of considerable debate is whether Black individuals possess "more" traits of psychopathy than do Whites. To address this issue, a meta-analysis of differences between these groups' scores on the Psychopathy Checklist--Revised (PCL-R; Hare, 1991) was performed, using 21 studies (N = 8,890) of correctional, substance abuse, and psychiatric samples. Blacks exceeded Whites by an average of less than 1 point on the PCL-R total score. Effect sizes for core interpersonal and affective traits of psychopathy (Factor 1) were sufficiently homogeneous to clearly interpret, although other features manifested statistically significant heterogeneity. Our finding that Blacks and Whites do not meaningfully differ in their levels of core psychopathic traits is consistent with community-based findings for self-report measures of psychopathy and clinical diagnoses of antisocial personality disorder.

Prototypical analysis of adolescent psychopathy: investigating the juvenile justice perspective.

The past ten years have seen a dramatic increase in the empirical investigation of psychopathic characteristics in children and adolescents. In general, the focus of this research has been on the validation of assessment instruments to evaluate psychopathy as well as concurrent and predictive validity. Little attention has been directed toward elucidating the core characteristics of this construct. The current study expands on previous research by asking juvenile justice personnel (424 juvenile detention and probation officers) to identify the core characteristics of the construct via prototypical analysis for both male and female adolescents. Results of separate factor analyses by gender revealed five identifiable dimensions: juvenile delinquency, serious/violent conduct problems, narcissistic/manipulation of others, impulsivity/acting out, and family problems. The results suggest that juvenile justice personnel focus on a wide range of behavioral indicators as indicative of adolescent psychopathy in addition to affective and interpersonal characteristics typically viewed as crucial to the construct by clinicians.
