Self-report measures of child and adolescent psychopathy as predictors of offending in four samples of justice-involved youth

The authors examined the relation between self-report psychopathy measures and official records of offending in four samples of justice-involved youth (total N = 447). Psychopathy measures included the Antisocial Process Screening Device (APSD) and a modified version of the Childhood Psychopathy Scale (mCPS). Measures of offending included the total number of preadmission arrest charges for three samples (n = 392) and the total number of offenses in the year following release for two samples (n = 138). Neither measure was a strong correlate of preadmission offenses. Although mCPS scores were associated with postrelease offending in one sample, effects for the APSD were observed only when reoffending was conceptualized as a dichotomous variable, indicating a lack of robustness in this association. The findings suggest caution in the use of self-report measures of psychopathic features for decision making with respect to issues of delinquency risk among justice-involved youth.     

Psychopathic features in a juvenile diversion population: reliability and predictive validity of two self-report measures

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 age = 14.4 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 CPS were excellent after deleting items that had poor corrected item-to-CPS total score correlations. Positive and statistically significant correlations for all measures were obtained with prospective measures of program failure (range 0.22-0.36) and rearrest at 1 year follow-up (range 0.33-0.56). Although further research is needed prior to the clinical use of these measures, these results signal the potential of such measures to inform clinical judgments regarding treatment compliance and risk with justice-involved youth.     

Using Force: Australian Newspaper Depictions of Contacts Between the Police and Persons Experiencing Mental Illness

The media creates and sustains knowledge about socially relevant issues such as crime, mental illness, and policing. Past research suggests that while the media portrayal of the police is undoubtedly complex, their portrayal of people experiencing mental illness remains mainly negative. The depiction of their encounters in the mass media is of considerable interest because of the influential role the media has on public opinion and debate; however, there is a lack of current research in this area. This study aimed to examine media items in the major newspapers across Australia between January 2006 and December 2007 (n = 77) to investigate their portrayal of this interface. The dominant themes encountered in the initial analysis depicted people experiencing mental illness as dangerous and a threat to the public, where the mental health system has failed to manage them adequately. Further analyses found that people experiencing mental illness were stigmatised in a third of the media items reviewed and were represented significantly more negatively in these encounters than the police. Implications of these findings and some suggestions regarding possible strategies that could improve socially responsible media reporting and public discourse on mental illness are proposed.     

Using self-esteem to disaggregate psychopathy,narcissism, and aggression

Past research offers conflicting conclusions regarding the associations between self-esteem, psychopathy, narcissism, and aggression. The current study clarified these associations by examining self-esteem level and stability as it relates to the factors of psychopathy and narcissism predicting aggression. Self-report assessments were administered to 118 undergraduates. While self-esteem instability was not related to psychopathy or narcissism, it was positively correlated with aggression. Additionally, those with the healthier aspects of narcissism and Factor 1 features of psychopathy had high self-esteem and less aggression, while those with more pathological narcissism and Factor 2 features of psychopathy had lower self-esteem and more aggression. Specifically, the relationship between psychopathy Factor 1 and aggression was partially mediated by lower self-esteem.     

Psychopathy and malingering of psychiatric disorder in criminal defendants

Because the use of deception is an important clinical characteristic of psychopathy, there is intuitive appeal to the idea that psychopathy and malingering are associated. There is, however, very little research showing that psychopaths are more likely to malinger. We classified a sample of criminal defendants as high, moderate, or low in psychopathy, based on PCL-R scores, and compared their scores on indices typically used to detect malingering on the MMPI-2, the PAI and the SIRS. The high psychopathy group scored significantly higher on the MMPI-2 F and F-K; the PAI NIM, and the SIRS, but not the MMPI-2 Fb, F(p), or the PAI RDF or Mal, lending some support for the DSM-IV recommendation that malingering should be considered whenever there is a diagnosis of antisocial personality disorder. Logistic regression analysis (LGA) revealed that Factor I but not Factor II of the PCL-R significantly discriminated malingerers from nonmalingerers with 75% correct classification. However, receiver operating characteristic (ROC) analysis revealed that psychopathy ratings had poor sensitivity and specificity in the detection of malingering. Calculation of the percentages of those exceeding accepted cut-offs on each of the malingering measures revealed that a high percentage of severe psychopaths did not attempt to feign psychiatric disorder. The results suggest that psychopathy is not a clinically useful indictor of malingering. The results are discussed in terms of confirmatory bias and the impact such a bias could have on the evaluation of criminal defendants.     

熟悉性对外群体同质性效应的影响

两个实验考查了年龄和性别群体中是否存在外群体同质性效应以及熟悉性对该种效应的影响。结果表明：1．年龄群体中存在明显的外群体同质性效应,这与青年群体和老年群体彼此不够熟悉有关;2．性别群体中不存在外群体同质性效应,这与青年男女群体彼此较为熟悉有关。     

Reliability and validity of two self-report measures of psychopathy

The present study assessed the psychometric properties and construct validity of two self-report measures of psychopathy in a male-college sample: the Levenson Psychopathy scales (LPS; Levenson, Kiehl, & Fitzpatrick, 1995) and the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996). Both the LPS and the PPI demonstrated good internal consistency, although selected items from the PPI correlated weakly with their respective factor scores, suggesting the need for further investigation of the factors' item content. The PPI showed stronger validity than the LPS in terms of convergent and discriminant validity of its factor scores and factor associations with two criterion variables, aggression, and anxiety. Overall, the current study provides greater support for the use of the PPI over the LPS in studies investigating psychopathic traits in nonclinical and nonforensic samples.     

Internal consistency reliability of the self-report antisocial process screening device

The self-report version of the Antisocial Process Screening Device (APSD) has become a popular measure for assessing psychopathic features in justice-involved adolescents. However, the internal consistency reliability of its component scales (Narcissism, Callous-Unemotional, and Impulsivity) has been questioned in several studies. This study evaluates the internal consistency reliability of the self-report APSD by examining various indices (e.g., Cronbach's alpha, mean interitem correlation) across 11 studies. Whereas the Narcissism and Impulsivity scales display moderate to good reliability, internal consistency indices for the Callous-Unemotional scale are consistently poor across studies. Suggestions are made for revisions to this scale that would substantially improve its internal consistency reliability.
