Relation between parenting stress and psychopathic traits among children

Parenting stress was examined as a correlate of psychopathic traits, specifically narcissism, callous/unemotional traits, and impulsivity, among school-aged children while controlling for the variance explained by aggressive behavior. Participants included 212 children ranging from 6 to 12 years of age (M = 8.3 years) who were admitted to an acute child psychiatric inpatient unit for treatment. Parents completed standardized measures of aggression (Child Behavior Checklist; CBCL), psychopathic traits (Antisocial Process Screening Device; APSD), and parenting stress (Parenting Stress Index; PSI) at the time of the child's admission. Multiple regression analyses revealed that high levels of the PSI dimension attachment difficulties were associated with high levels of narcissism and callous/unemotional traits among the children while statistically controlling for aggression. The PSI dimension role restriction was also found to be negatively related to narcissism. These findings suggest that specific aspects of parenting stress may be related to child psychopathic traits and might aid with conceptualizing and developing treatment approaches for childhood behavior problems.     

Assessment of Psychopathic Traits in Singaporean Adolescents: Validation of the Antisocial Process Screening Device (APSD)

There is little knowledge available concerning psychopathic traits in Asian adolescents; a lack of a suitable measurement instrument for assessing psychopathy in Asian societies may account for this. This study aimed to validate a widely used scale in the West — the Antisocial Process Screening Device (APSD) — in Singaporean school-based and at-risk adolescents. Using an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA), this study examined the two-factor (i.e., grandiose-manipulative/impulsive traits and callous-unemotional traits) and three-factor (i.e., grandiose-manipulative traits, impulsivity, and callous-unemotional traits) models of the APSD in 1027 school-based and 113 at-risk adolescents. School samples are adolescents from three secondary schools, while at-risk samples are adolescents who manifest different types of delinquent behaviors and are either placed in more structured settings or need closer supervision although they have not violated the law. Gender invariance was further tested in the school-based sample by conducting a multigroup CFA. The convergent validity of the APSD was also investigated in the school-based sample. For the school-based adolescents, the APSD revealed that the three-factor model provided a superior fit over the two-factor model and the factorial invariance across gender. Significant relationships between the three dimensions of the APSD and aggression and delinquency support the convergent validity of the APSD. As for the at-risk adolescents, both the two- and three-factor models were acceptable, but the two-factor model was preferred as it was parsimonious and it aligned with the conceptualized characteristics of psychopathic traits. Findings suggest that the APSD is a reliable and sound instrument for measuring psychopathic traits in Asian school-based and at-risk adolescents.     

Factor Structure and Construct Validity of the Dutch Version of the Antisocial Process Screening Device

The goal of the present study was to evaluate the factor structure and construct validity of the Antisocial Process Screening Device (APSD) in a community sample of Dutch adolescents. Confirmatory factor analyses supported the two- and three-factor model, but the two-factor model (Callous-Unemotional and Impulsivity/Conduct Problems) was more parsimonious. Model fit was invariant across gender. Interrater reliability was good and internal consistency of the factors was modest to good, with the exception of the Callous-Unemotional factor. Convergence with the APSD self-report version, divergence with the Big Five personality dimensions of Agreeableness and Conscientiousness, and expected gender differences in mean APSD scores reproduced findings obtained in American samples, supporting the cross-cultural validity of the APSD.     

Attention Network Performance and Psychopathic Symptoms in Early Adolescence: An ERP Study

Reaction time (RT) and event-related potential (ERP) measures were used to examine the relationships between psychopathic symptoms and three major attention networks (alerting, orienting, and executive attention) among a community sample of youth. Antisocial Process Screening Device (APSD; Frick and Hare 2001) total and subscale scores were negatively correlated with ERP measures of attentional alerting, indicating that youth with psychopathic symptoms had difficulty using warning cues to prepare for upcoming targets. APSD total scores were not related to performance on measures of orienting or executive attention, although weaker executive attention was found among youth with higher scores on the Impulsivity subscale. These findings support attention-based models of psychopathy and provide evidence of specific deficits in attentional alerting among youth with psychopathic traits. Deficiencies in attentional alerting may be related to noradrenergic functioning and may have cascading effects on higher order cognitive and affective processing.     

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.     

The reliability, stability, and predictive utility of the self-report version of the Antisocial Process Screening Device

The psychometric properties of the self-report version of the Antisocial Processes Screening Device (APSD; Frick & Hare, 2001), a rating scale developed to assess traits associated with the construct of psychopathy in youth, was tested in a sample of 91 non-referred young adolescents with an average age of 13.38 (SD = 1.75) at the initial assessment. The sample was recruited from a large community-wide screening, where youth with conduct problems and youth high on psychopathic traits were over-sampled. The sample was reassessed three times at yearly intervals. The self-report scores on the APSD showed moderate correlations with parent ratings of psychopathic traits, were moderately stable across 1-2 years, and showed significant correlations with measures of antisocial behavior both concurrently and predictively. One major weakness of the self-report ratings was the low internal consistency of the subscales, which were much lower than the internal consistency found on the parent report version of the scale.     

The relationship between psychopathic features, violence and treatment outcome: the comparison of three youth measures of psychopathic features

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 and strongly related to antisocial behavior and to the days required to progress in treatment than the PCL:YV. The following issues are discussed: (i) implications of the potential impact of measurement format on the understanding and predictive validity of youth psychopathy features and measures; (ii) the differential predictive validity of self-report versus clinician-administered measures; and (iii) the potential practical utility of measures of psychopathic features in youth.     

The relationship between the youth psychopathic traits inventory and psychopathology in a U.S. community sample of male youth

The Youth Psychopathic Traits Inventory (YPI) is a self-report measure of juvenile psychopathic traits. Validity data for this measure are limited, especially for nonreferred samples. This report investigated the concurrent validity of the YPI by assessing 171 nonreferred male youth (M age = 12.96 years) with a battery of self-, parent-, and peer-report measures including the Child Behavior Checklist (CBCL), the Reactive-Proactive Aggression Questionnaire (RPQ), the Antisocial Process Screening Device (APSD), and a peer-sociometric measure of aggression. Results confirmed the expected correlations between the YPI and measures of proactive aggression, other externalizing and internalizing behavior, and parent-report psychopathic-like traits. In addition, cluster analyses of YPI scores revealed 2 groups of youth (low vs. high) who scored differently on measures of externalizing behavior. This study supports the utility of the YPI as a research tool for assessing juvenile psychopathic traits.     

Psychopathic personality as a distinctive indicator of severity and persistence for child and youth conduct problems

Conduct problems are among the most discussed behavioral problems during childhood and adolescence. Given their heterogeneity, in recent years, researchers on this topic have called for delineation of early-onset conduct problems on the basis of affective, interpersonal and behavioral traits that resemble adult psychopathy. The present study aims to analyze, from both a cross-sectional and longitudinal perspective, whether early psychopathic traits allow identification of a group of individuals defined by severe and persistent behavioral problems. To achieve this goal, data from a sample of 192 children (aged 6 to 11) were analyzed; from this sample, 133 children were followed-up in a new data collection that took place three years later. From the data obtained with the mCPS and CBCL (parents), and APSD and TRF (teachers), we observed that children who showed early psychopathic traits, also showed greater frequency, severity and persistence of conduct problems. These results suggest the need to take into account the role of psychopathic traits (particularly, affective and interpersonal) as risk factors to delimit the most serious and persistent patterns of externalizing behavior.     

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.     

A New Measure to Assess Psychopathic Personality in Children: The Child Problematic Traits Inventory

Understanding the development of psychopathic personality from childhood to adulthood is crucial for understanding the development and stability of severe and long-lasting conduct problems and criminal behavior. This paper describes the development of a new teacher rated instrument to assess psychopathic personality from age three to 12, the Child Problematic Traits Inventory (CPTI). The reliability and validity of the CPTI was tested in a Swedish general population sample of 2,056 3- to 5-year-olds (mean age?=?3.86; SD?=?.86; 53 % boys). The CPTI items loaded distinctively on three theoretically proposed factors: a Grandiose-Deceitful Factor, a Callous-Unemotional factor, and an Impulsive-Need for Stimulation factor. The three CPTI factors showed reliability in internal consistency and external validity, in terms of expected correlations with theoretically relevant constructs (e.g., fearlessness). The interaction between the three CPTI factors was a stronger predictor of concurrent conduct problems than any of the three individual CPTI factors, showing that it is important to assess all three factors of the psychopathic personality construct in early childhood. In conclusion, the CPTI seems to reliably and validly assess a constellation of traits that is similar to psychopathic personality as manifested in adolescence and adulthood.     

The P-psychopathy continuum: Facets of Psychoticism and their associations with psychopathic tendencies

Eysenck proposed that psychopathy is at the extreme end of the Psychoticism (P) personality dimension (Eysenck & Eysenck, 1976). This study examined (i) whether psychopathy-relevant P items of the EPQ-R can form psychometrically valid facets that map onto the conceptualization of the two-, three- or four-factor models of psychopathy using confirmatory factor analysis (N = 577) in a normal population; and (ii) whether those P-facets have criteria-related validity in associations with self-reported primary and secondary psychopathy, impulsivity (subsample N = 306), and measures of trait empathy and aggression (subsample N = 212). The four-factor model incorporating affective, interpersonal, impulsive, and antisocial facets of P was superior to the two-factor model; however, the three-factor conceptualization excluding the antisocial P-facet was the best fit. The facets show predicted divergent associations with primary and secondary self-reported psychopathy and trait measures. Findings are discussed in light of Eysenck’s P-psychopathy continuity hypothesis and the applicability of facet approaches to the prediction of psychopathic and antisocial tendencies.     

Secondary psychopathy,but not primary psychopathy,is associated with risky decision-making in noninstitutionalized young adults

Although risky decision-making has been posited to contribute to the maladaptive behavior of individuals with psychopathic tendencies, the performance of psychopathic groups on a common task of risky decision-making, the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994), has been equivocal. Different aspects of psychopathy (personality traits, antisocial deviance) and/or moderating variables may help to explain these inconsistent findings. In a sample of college students (N = 129, age 18–27), we examined the relationship between primary and secondary psychopathic features and IGT performance. A measure of impulsivity was included to investigate its potential as a moderator. In a joint model including main effects and interactions between primary psychopathy, secondary psychopathy and impulsivity, only secondary psychopathy was significantly related to risky IGT performance, and this effect was not moderated by the other variables. This finding supports the growing literature suggesting that secondary psychopathy is a better predictor of decision-making problems than the primary psychopathic personality traits of lack of empathy and remorselessness.     

The validity of the Antisocial Process Screening Device as a self-report measure of psychopathy in adolescent offenders

There is a growing interest in the assessment of adolescent psychopathy to enable early treatment and intervention. Recently, a self-report measure has been developed to assess psychopathic traits in adolescents. The Antisocial Process Screening Device (APSD), a self-report measure of psychopathic traits, and the Psychopathy Checklist: Youth Version (PCL:YV), a clinical rating scale, were administered to a sample of 100 incarcerated male adolescent offenders to assess the concurrent validity of the APSD. Results indicated that the APSD had limited concurrent validity with respect to the PCL:YV and that there appears to be a method effect in the measurement of psychopathy. Thus, it appears the APSD did not assess psychopathy in a manner parallel to that of the PCL:YV.     

Psychophysiological and Neuropsychological Characteristics of Non-Incarcerated Adult Males with Higher Levels of Psychopathic Personality Traits

Although much research on psychopathic individuals has been conducted in incarcerated settings, there is increasing interest in studying adults with higher levels of psychopathic traits in the general population. The present study investigated differences in psychophysiological response and neuropsychological functioning between undergraduate males with higher levels of psychopathic traits (higher-p) and undergraduate males with lower levels of psychopathic traits (lower-p). Participants completed self-report measures and neuropsychological measures, and skin conductance response was measured during a risk-taking and affective-picture viewing task. Consistent with previous findings among samples of incarcerated psychopaths, higher-p adults exhibited diminished responses to aversive and positive affective stimuli and were more disinhibited on a motoric response inhibition task. Contrary to expectations, higher-p adults made marginally better decisions on a risky decision making task. Findings were discussed in relation to Gao and Raines’ (Behavioral Sciences & the Law 28(2) 194–210, 2010) model of the neurobiological underpinnings of adults with higher levels of psychopathic traits in non-incarcerated settings, and offer evidence that higher-p adults have both adaptive and non-adaptive traits.     

Genetic and environmental bases of childhood antisocial behavior: a multi-informant twin study

Genetic and environmental influences on childhood antisocial and aggressive behavior (ASB) during childhood were examined in 9- to 10-year-old twins, using a multi-informant approach. The sample (605 families of twins or triplets) was socioeconomically and ethnically diverse, representative of the culturally diverse urban population in Southern California. Measures of ASB included symptom counts for conduct disorder, ratings of aggression, delinquency, and psychopathic traits obtained through child self-reports, teacher, and caregiver ratings. Multivariate analysis revealed a common ASB factor across informants that was strongly heritable (heritability was .96), highlighting the importance of a broad, general measure obtained from multiple sources as a plausible construct for future investigations of specific genetic mechanisms in ASB. The best fitting multivariate model required informant-specific genetic, environmental, and rater effects for variation in observed ASB measures. The results suggest that parents, children, and teachers have only a partly "shared view" and that the additional factors that influence the "rater-specific" view of the child's antisocial behavior vary for different informants. This is the first study to demonstrate strong heritable effects on ASB in ethnically and economically diverse samples.     

Evaluating the generalizability of a fear deficit in psychopathic African American offenders

Laboratory studies of psychopathy have yielded an impressive array of etiologically relevant findings. To date, however, attempts to demonstrate the generalizability of these findings to African American psychopathic offenders have been largely unsuccessful. The fear deficit has long been regarded as the hallmark of psychopathy, yet the generalizability of this association to African American offenders has not been systematically evaluated. In this study, we used an instructed fear paradigm and fear-potentiated startle to assess this deficit and the factors that moderate its expression in African American offenders. Furthermore, we conceptualized psychopathy using both a unitary and a two-factor model, and we assessed the constructs with both interview-based and self-report measures. Regardless of assessment strategy, results provided no evidence that psychopathy relates to fear deficits in African American offenders. Further research is needed to clarify whether the emotion deficits associated with psychopathy in European American offenders are applicable to African American offenders.     

Psychopathy scores and violence among juvenile offenders: a multi-measure study

This study examined the relations between psychopathy scores and violent behavior in 113 incarcerated adolescents. We compared the results of four different instruments designed to assess psychopathy features among juveniles-the Psychopathy Checklist: Youth Version (PCL:YV), two versions of the Antisocial Processes Screening Device (APSD), and a Psychopathy Content scale on the Millon Adolescent Clinical Inventory (MACI). We found that PCLY:YV scores were significantly correlated with violent offense history, unadjudicated violence, and institutional violence, as well as measures of the severity and instrumentality of prior violence. Receiver operating characteristic analyses generated statistically significant effect sizes (AUC values) ranging from 0.64 to 0.79. The three other measures generated statistically significant correlations with one or more of the violence criteria, although correlations and effect sizes tended to be smaller in magnitude. Our results offer some support for the validity of these measures of psychopathic features, and the value of the PCL:YV in particular, with respect to short-term measures of violence outcome among juvenile offenders.     

Psychopathic Traits in Youth: Is There Evidence for Primary and Secondary Subtypes?

The current study employed model-based cluster analysis in a sample of male adolescent offenders (n = 94) to examine subtypes based on psychopathic traits and anxiety. Using the Psychopathy Checklist: Youth Version (PCL:YV; Forth et al. 2003) and the self-report Antisocial Process Screening Device (APSD; Caputo et al. 1999), analyses identified three clusters in males that varied in the severity of psychopathic traits (low, moderate, and high) and anxiety. The high psychopathic group exhibited more negative personality traits and was judged to be at greater risk for dangerousness whereas the low psychopathic group exhibited more positive personality traits and was judged to be at lower risk for dangerousness. Implications regarding potential developmental differences between adolescent and adult psychopathy, as well as treatment considerations are discussed.     

Confirmatory Factor Analysis of the School Refusal Assessment Scale-Revised: Child and Parent Versions

The School Refusal Assessment Scale-Revised (SRAS-R) is an instrument designed to evaluate the relative strength of four functional conditions of school refusal behavior in youth. Although previous work has shown the scale's child and parent versions to show good reliability, verification of the SRAS-R factor structure remains necessary. The present study investigated administrations of the child and parent versions of the SRAS-R (SRAS-R-C and SRAS-R-P) using confirmatory factor analysis. For both measures, four-factor models were supported following the removal of two SRAS-R-C and three SRAS-R-P items. Three-factor and two-factor models for each SRAS-R version were not supported. Ramifications of these results for use of the SRAS-R are discussed.
