The Macarthur Adjudicative Competence Study: The Development And Validation Of A Research Instrument, Steven Hoge, Richard Bonnie, Norman Poythress, John Monahan
The Macarthur Adjudicative Competence Study: The Development And Validation Of A Research Instrument, Steven Hoge, Richard Bonnie, Norman Poythress, John Monahan
Norman Poythress
Assessment of competence to stand trial is a common evaluation that can have substantial consequences for defendants and the criminal justice system. Despite a voluminous literature, much remains unknown. An obstacle to progress in understanding what is better termed ldquoadjudicative competencerdquo is the absence of structured, standardized research measures for assessment of defendants. This article presents the legal framework, assessment strategy, instrument description, psychometric properties, and construct validation of the MacArthur Structured Assessment of the Competencies of Criminal Defendants (MacSAC-CD). The measures meet or exceed accepted indices of internal consistency, and interscorer agreement. Observed patterns of correlations among measures support …

Antisocial personality disorder (ASPD) is associated with suicide, violence, and risk-taking behavior and can slow response to first-line treatment for Axis I disorders. ASPD may be assessed infrequently because few efficient diagnostic tools are available. This study evaluated 2 promising self-report measures for assessing ASPD—the ASPD scale of the Personality Diagnostic Questionnaire-4 (PDQ-4; S. E. Hyler, 1994) and the Personality Assessment Inventory (PAI; L. Morey, 1991, 2007)—as well as the ASPD module of the Structured Clinical Interview for DSM–IV Axis II (SCID-II; M. B. First, R. L. Spitzer, M. Gibbon, J. B. W. Williams, & L. S. Benjamin, 1997). The …
Mentally Ill And Non-Mentally Ill Defendants' Abilities To Understand Information Relevant To Adjudication: A Preliminary Study, Steven Hoge, Norman Poythress, Richard Bonnie, Marlene Eisenberg
Mentally Ill And Non-Mentally Ill Defendants' Abilities To Understand Information Relevant To Adjudication: A Preliminary Study, Steven Hoge, Norman Poythress, Richard Bonnie, Marlene Eisenberg
Norman Poythress
The legal construct of competence to stand trial, or “adjudicative competence,” is based on the premise that some mentally disordered defendants have impaired abilities when compared with most defendants and that adjudication should be barred if these competence-related abilities are significantly impaired. Where the line is drawn between sufficient and insufficient abilities has important consequences: as a result of being adjudicated incompetent, defendants may be detained and treated involuntarily and their trials will be delayed. However, no studies have systematically compared the capacities of relevant groups of defendants. In this studv. 84 criminal defendants—42 of whom were hospitalized as incompetent …

The Broward Mental Health Court: Process, Outcomes, And Service Utilization, Roger Boothroyd, Norman Poythress, Annette Christy, John Petrila
Norman Poythress
Mental health courts are one of a variety of special jurisdiction courts that have been created in a number of countries, including the United States (Petrila, 2003). While there is no prototypical mental health court (Steadman, Davidson, & Brown, 2001; Watson, Luchins, & Hanrahan, 2001), most of those in existence today share several common characteristics. These include (a) the creation of a special docket (usually, but not always, nonviolent misdemeanants with mental illness) that is (b) handled by a particular judge, with (c) a primary goal of diverting defendants from the criminal justice system and into treatment (Goldkamp & Irons-Guynn, …
Psychopathic Features In A Juvenile Diversion Population: Reliability And Predictive Validity Of Two Self-Report Measures, Diana Falkenbach, Norman Poythress, Kathleen Heide
Psychopathic Features In A Juvenile Diversion Population: Reliability And Predictive Validity Of Two Self-Report Measures, Diana Falkenbach, Norman Poythress, Kathleen Heide
Norman Poythress
The reliability and predictive validity of two experimental self-report versions of two measures of psychopathic features in youth, the Antisocial Process Screening Device (APSD: Frick & Hare, 2001) and a modified version of the Child Psychopathy Scale (CPS: Lynam, 1997) were examined in a sample of 69 arrested youth (M age¼14.4 years) referred to a juvenile diversion program. Parents or legal guardians completed parent-rating versions of the same measures. Reliability indicators for the APSD total measure were satisfactory although internal consistency indices (coefficient alpha) for the Callous/Unemotional and Impulsive/Conduct Problems scales were slightly lower than desirable. Reliability indicators for the …
Evaluation Of The Hare-Pscan In A Non-Clinical Population, Cristal Elwood, Norman Poythress, Kevin Douglas
Evaluation Of The Hare-Pscan In A Non-Clinical Population, Cristal Elwood, Norman Poythress, Kevin Douglas
Norman Poythress
Using 100 university undergraduates as participants, this study examined the structural reliability and construct validity of Hare and Hervé's P-SCAN (Hare & Hervé, 1999) a 90-item measure that purports to serve as an “… early warning system” or “rough screening device” (p. 1) for identifying individuals with substantial psychopathic features. Internal consistency indices (e.g. Cronbach's α, mean inter-item correlations) for the three P-SCAN subscales (Interpersonal, Affective, Lifestyle) suggested excellent reliability. Statistically significant, though modest correlations (range 0.21–0.33) were obtained in 5 of 6 comparisons with the self-report Primary psychopathy and Secondary psychopathy scales developed by Levenson, Kiehl, and Fitzpatrick (1995) …
Psychometric Properties Of Carver And White’S (1994) Bis/Bas Scales In A Large Sample Of Offenders, Norman Poythress, Jennifer Skeem, John Weir, Scott Lilienfeld
Psychometric Properties Of Carver And White’S (1994) Bis/Bas Scales In A Large Sample Of Offenders, Norman Poythress, Jennifer Skeem, John Weir, Scott Lilienfeld
Norman Poythress
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 1515 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, …
The Relationship Between Psychopathic Personality Features And Malingering Symptoms Of Major Mental Illness, Norman Poythress, John Edens, M. Watkins
The Relationship Between Psychopathic Personality Features And Malingering Symptoms Of Major Mental Illness, Norman Poythress, John Edens, M. Watkins
Norman Poythress
This study examined the relationship between psychopathy and malingering in a subsample of male prison inmates (n D 55) participating in a larger study of the clinical utility of various assessment measures in correctional settings. Participants’ capacity to feign major mental illness successfully was evaluated using standard cutoff scores for the detection of malingering on a variety of instruments, including the Structured Inventory of Malingered Symptomatology (SIMS; G. P. Smith & G. O. Burger, 1997), the Structured Interview of Reported Symptoms (SIRS; R. Rogers, R. M. Bagby, & S. E. Dickens, 1992), and the Personality Assessment Inventory (PAI; L. Morey, …

Stability Of Psychiatric Patients' Perceptions Of Their Admission Experience, Michele Cascardi, Norman Poythress, Lee Ritterband
Stability Of Psychiatric Patients' Perceptions Of Their Admission Experience, Michele Cascardi, Norman Poythress, Lee Ritterband
Norman Poythress
The primary aim of this study was to evaluate the stability (i.e., consistency of patients’ responses over time) of newly developed scales to measure the admission experience of psychiatric hospitalization. Eighty-four psychiatric patients involuntarily committed to a crisis stabilization unit participated. All participants were admitted under an emergency petition or ex parte order for a psychiatric evaluation. Patients were interviewed soon after admission (M 5 3.33 days, SD 5 1.86 days). The test–retest interval was 24–48 hours with most (83.3%) re-evaluated at 24 hours. Overall, the measures showed acceptable levels of stability (r ’s range from .62 to .72). Factors …
Correlates Of Perceived Coercion During Psychiatric Hospital Admission, Michelle Cascardi, Norman Poythress
Correlates Of Perceived Coercion During Psychiatric Hospital Admission, Michelle Cascardi, Norman Poythress
Norman Poythress
The objectives of this study were to replicate the study of C. W. Lidz et al (see record 1996-15479-001); examine the differences in perceptions about hospital admission for voluntary and involuntary patients (16 yr olds and older), all of whom had been involuntarily detained initially for psychiatric evaluation; and examine the impact of community members vs hospital staff, locus of control, and psychiatric symptom severity on patients' perceptions of coercion. Results substantiate earlier findings of Lidz et al in that legal status (involuntary), procedural justice, and negative pressures are significantly related to perceived coercion. Although all patients in this study …

Further Validation Of The Psychopathic Personality Inventory Among Offenders: Personality And Behavioral Correlates, John Edens, Norman Poythress, M. Watkins
Norman Poythress
The Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) is a relatively new self-report measure that has shown considerable promise as an index of psychopathic traits in both nonoffender and offender samples. The present study examined the construct validity and predictive utility of the PPI by examining its association with theoretically relevant scales of the Personality Assessment Inventory (PAI; Morey, 1991) among 60 male prison inmates, and its ability to predict institutional misbehavior in an expanded sample (n = 89). As expected, correlations with the PAI scales were highest for the Antisocial Features (ANT) and Aggression (AGG) scales (rs = …
Construct Validity Of The Youth Psychopathic Features Inventory (Ypi) And The Antisocial Process Screening Device (Apsd) With Justice Involved Adolescents, Norman Poythress, Richard Dembo, Jennifer Wareham, Paul Greenbaum
Construct Validity Of The Youth Psychopathic Features Inventory (Ypi) And The Antisocial Process Screening Device (Apsd) With Justice Involved Adolescents, Norman Poythress, Richard Dembo, Jennifer Wareham, Paul Greenbaum
Norman Poythress
Two measures of psychopathic features in youths, the self-report version of the Antisocial Process Screening Device (APSD) and the Youth Psychopathic traits Inventory (YPI) were administered to 165 youths in a juvenile diversion program. For both measures, internal consistency was poor for the scales that assess the affective domain of psychopathic features; otherwise, internal consistency was excellent for the YPI and generally superior to that of the APSD. However, the published three-factor models for both measures did not replicate when examined using confirmatory factor analysis. Both measures obtained the expected correlations with measures of a variety of criminal justice (e.g., …

The Macarthur Adjudicative Competence Study: A Comparison Of Criteria For Assessing The Competence Of Criminal Defendants, Richard Bonnie, Steven Hoge, John Monahan, Norman Poythress
Norman Poythress
A set of measures assessing competence-related abilities was administered to three groups of criminal defendants: a group committed for restoration of competence, a group identified by jail personnel as mentally ill but not incompetent, and a group without identified mental disorder. Data from this study were used to test key assumptions bearing on the legal criteria for adjudicative competence. The. data show that among defendants able to understand the nature and purpose of the criminal proceedings, a significant proportion have an impaired ability to appreciate their situations as criminal defendants or to communicate relevant information to counsel; among defendants able …

Evaluating The Efficiency And Community Safety Goals Of The Broward County Mental Health Court, Annette Christy, Norman Poythress, Roger Boothroyd, John Petrila
Norman Poythress
Mental health courts have developed as one response to persons with mental illness who are involved with the criminal justice system. This study investigated the efficiency and safety goals of one such court in Broward County, FL. Mental health court (MHC) clients spent significantly fewer days in jail for the index arrest associated with study enrollment than a comparison group. MHC clients had similar survival time to re-arrest up to one year after study enrollment. MHC clients did not significantly differ from the comparison group in selfreported aggressive acts over an 8 month follow-up period, while they did self-report significantly …

Procedural Preferences, Perceptions Of Fairness, And Compliance With Outcomes: A Study Of Alternatives To The Standard Adversary Trial Procedure, Norman Poythress
Norman Poythress
Mental health professionals (N=198) read a vignette describing malpractice case and were asked to imagine themselves in the role of defendant. Using a between-subjects design, each subject was offered two possible trial procedures for resolving the case, the standard adversary procedure (ADVERS) and one of five possible hybrid procedures. Using scales that juxtaposed these two procedures, subjects provided judgments on 12 procedural justice dimensions. A series of regression analyses examined the most important determinants of PREFERENCE judgments, FAIRNESS ratings, and ratings of imagined COMPLIANCE with trial outcomes. PREFERENCE raings were significantly influenced by perceived FAIRNESS of the procedures and by …

Norman Poythress
Few studies have compared self-report and clinician-administered measures of youth psychopathic features in juvenile-justice settings in terms of antisocial behavior and treatment indices. In a sample of 85 adjudicated delinquents, the predictive validities of the Antisocial Process Screening Device (APSD), the modified Childhood Psychopathy Scale (mCPS), and the Hare Psychopathy Checklist: Youth Version (PCL:YV) were tested. Three indices of institutional antisocial behavior (physical aggression; verbal aggression; administrative infractions) and two indices of treatment progress (time to treatment level promotion; whether treatment levels were dropped) were used as external correlates. The self-report measures (mCPS more so than APSD) were more consistently …

Procedural Justice In The Context Of Civil Commitment: An Analogue Study, Michelle Cascardi, Norman Poythress, Alicia Hall
Norman Poythress
Procedural justice theory posits that the process by which disputes are resolved in¯uences perceptions of fairness and satisfaction with outcomes, even if the outcomes are unfavorable. Within the context of civil commitment, Tyler (1992) has suggested that enhancing respondents' perceptions of procedural justice (i.e., participation, dignity, and trust) during commitment proceedings might facilitate accommodation to an adverse judicial determination (i.e., commitment) and subsequently enhance therapeutic outcomes. The study reported here used videotapes of mock commitment hearings to examine whether patients committed for involuntary treatment are sensitive to procedural justice manipulations. Results suggest that patients are sensitive to procedural justice manipulations …

Relationships Between Psychopathy And Impulsivity In The Domain Of Self-Reported Personality Features, James Ray, Norman Poythress, John Weir, Angela Rickelm
Norman Poythress
Impulsivity is widely accepted as a characteristic of psychopathy. However, both psychopathy and impulsivity are multi-faceted constructs, and theory suggests that primary and secondary variants of psychopathy may differ in their manifestations of impulsivity-related features. Using a sample of 92 offenders, this study used the fearless dominance (FD) and self-centered impulsivity (SCI) factors of the psychopathic personality inventory - revised (PPI-R; Lilienfeld, S.O., & Widows, M.R. (2005). Psychological assessment inventory - revised (PPI-R). Lutz, FL: Psychological Assessment Resources.), respectively, as proxy indicators of primary and secondary psychopathy, and examined their relations to multiple impulsivity- related constructs. Bivariate and hierarchical regression …

Psychopathic Personality Or Personalities? Exploring Potential Variants Of Psychopathy And Their Implications For Risk Assessment, Jennifer Skeem, Norman Poythress, John Edens, Scott Lilienfeld
Psychopathic Personality Or Personalities? Exploring Potential Variants Of Psychopathy And Their Implications For Risk Assessment, Jennifer Skeem, Norman Poythress, John Edens, Scott Lilienfeld
Norman Poythress
Although psychopathy typically has been construed as a relatively uniform construct, seminal theories and contemporary research suggest that it may be heterogeneous. In this article, the most promising literature is distilled to distinguish among potential variants of antisocial personality disorder (APD) that can be derived from, and informed by, modern conceptions of psychopathy. This analysis suggests that there are primary and secondary variants of psychopathy, which may be distinguished based on the extent to which they are heritable and are characterized by affective deficits, impulsivity, trait anxiety, and characteristics of borderline and narcissistic personality disorders (NPD). These variants also may …
The Competence-Related Abilities Of Women Criminal Defendants, Norman Poythress, Steven Hoge, Richard Bonnie, John Monahan
The Competence-Related Abilities Of Women Criminal Defendants, Norman Poythress, Steven Hoge, Richard Bonnie, John Monahan
Norman Poythress
A new research instrument, the MacArthur Structured Assessment of Competencies of Criminal Defendants (MacSAC-CD), was administered to three groups of women defendants: those adjudicated incompetent and committed to forensic hospitals for treatment (n = 38), jail inmates receiving mental health treatment (n = 18) who had not been adjudicated incompetent, and randomly selected jail inmates (n = 50). Measures of the competence-related abilities of understanding and reasoning were found to have satisfactory indices of internal consistency (coefficient a), and all measures correlated in the expected direction with measures of global psychopathology, psychoticism, and verbal cognitive functioning. Between- group mean scores …

Effects Of State Organizational Structure And Forensic Examiner Training On Pre-Trial Competence Assessments, John Edens, Norman Poythress, Robert Nicholson, Randy Otto
Norman Poythress
States differ widely in their delivery of pretrial forensic evaluation services, in terms of organizational structure and training requirements of forensic examiners. It was hypothesized that defendants adjudicated incompetent to proceed in states using community-based, private-practitioner systems would show less impairment on a competence assessment measure, the MacArthur Competence Assessment Tool-Criminal Adjudication (MacCAT-CA), than defendants adjudicated incompetent in states using traditional, inpatient systems. It also was hypothesized that mean MacCAT-CA scores for incompetent defendants from states requiring forensic training/certification would be lower than for defendants from states lacking such requirements. Results indicated significant differences across the four types of service …

The Factor Structure And Convergent Validity Of The Aggression Questionnaire In An Offender Population, Tamra Williams, Jenine Boyd, Michele Cascardi, Norman Poythress
Norman Poythress
The study examined whether the 4-factor structure of the Aggression Questionnaire (AQ; A. H. Buss and M. Perry, see record 1993-00039-001), consisting of Physical Aggression, Verbal Aggression, Hostility, and Anger, would replicate in an offender population. The AQ and Novaco's Anger Scale (NAS; R. Novaco, 1994) were administered to 200 adult offenders. The results of a confirmatory analysis suggested that the 4-factor model is a poor fit in an offender population. A 2-factor model was suggested: 1 factor combines Physical Aggression and Anger; the other combines Verbal Aggression and Hostility. Evidence of convergent validity of the 2-factor model was provided …

Rediversion In Two Postbooking Jail Diversion Programs In Florida, Marcus Boccaccini, Annette Christy, Norman Poythress, David Kershaw
Rediversion In Two Postbooking Jail Diversion Programs In Florida, Marcus Boccaccini, Annette Christy, Norman Poythress, David Kershaw
Norman Poythress
OBJECTIVE: Patterns of rediversion in two postbooking jail diversion programs in Florida were examined to better understand the extent to which diversion programs served repeating clients. Rediversion occurs when a former or current diversion program participant is booked into jail on a new charge and diverted once again through the same diversion program. METHODS: Data from 18 months of consecutive entries into the Hillsborough County jail diversion program (N=336) and Broward County mental health court (N=800) were examined. RESULTS: Similar rediversion patterns were observed for the two diversion programs. About one-fifth of those who were diverted during the 18-month study …

Norman Poythress
This article describes the development of a new clinical instrument for use in assessments of adult criminal defendants' competence to proceed to adjudication, the MacArthur Competence Assessment Tool-Criminal Adjudication (MacCAT-CA). The MacCAT-CA was derived from a more comprehensive research instrument (MacArthur Structured Assessment of Competencies of Criminal Defendants; Hoge, Bonnie, Poythress, Monahan, & Eisenberg, 1997) on the basis of considerations efface validity for use in legal contexts, psychometric analyses, and advice from mental health experts who reviewed an earlier prototype. This article presents the results from an National Institute of Mental Healthsponsored validation study that investigated the psychometric properties of …
