Psychopathy and suicide: A multisample investigation.

Evidence suggests that behavioral aspects of psychopathy are associated with suicidal behavior, whereas the affective and interpersonal aspects are not. The authors tested the robustness of this bifurcated association across 1,711 persons and 12 samples of adult and juvenile criminal offenders, forensic psychiatric patients, and civil psychiatric patients. The authors observed a small but significant partial correlation (.13) between the behavioral/impulsive lifestyle features of psychopathy and suicidality, but no effect for affective/interpersonal features. Several method and sample features (mental disorder; psychopathy and suicidality measurement format) significantly strengthened or weakened this association. The authors conclude that it is not possible to speak of "the" association between psychopathy and suicide, but that this relationship appears to be partially dependent on methodological (i.e., self-report vs. clinician-administered psychopathy measures) and sample composition (i.e., age; mental illness) factors. Recommendations for practice are provided, including that clinicians should not consider psychopathy a buffer against suicidal behavior.

Psychopathy and Offending From Adolescence to Adulthood: A 10-Year Follow-Up.

This study examined the predictive validity of the Hare Psychopathy Checklist: Youth Version (PCL:YV; A. E. Forth, D. S. Kosson, & R. D. Hare, 2003) from adolescence to early adulthood. The authors coded the PCL:YV using file information and collected criminal record information over a 10-year follow-up period on 157 boys, ages 12 through 18, referred to Youth Forensic Psychiatric Services for assessment in 1986. The risk for violence into early adulthood was greater among those with high PCL:YV scores than among those with low scores, even after controlling for conduct disorder, age at first offence, and history of violent and nonviolent offending. These results indicate that the PCL:YV provides meaningful information about young offenders' risk for violence into early adulthood. Clinical implications are discussed, with reference to pertinent ethical issues. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Disruptive Behavior and School Grades: Genetic and Environmental Relations in 11-Year-Olds.

Disruptive behavior may be associated with poor academic achievement due to covariance with attention problems and low IQ. Evidence is based on clinical samples and on associations between problem behaviors in young children and later achievement difficulties. The contemporaneous relations and their genetic and environmental influences have not been understood. Using the population-based Minnesota Twin Family Study, the authors observed this pattern of associations in 11-year-olds. About 75% of variance in latent inattention, ability, behavior, and school grades variables was genetic. Genetic influences on inattention and grades and on ability and grades were highly overlapping. Those on disruptive behavior were less closely related.

Confirmatory Factor Analysis of the Psychopathy Checklist: Screening Version in Offenders With Axis I Disorders.

One hundred forty-nine inpatients within a maximum security psychiatric facility were assessed with the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995). Within the total sample, 68% had a psychotic disorder and 30% met criteria for psychopathy. Using confirmatory factor analysis, the authors tested the 2-factor PCL:SV model of psychopathy and recent 3- and 4-factor models. Results indicated good fit for each model, with the 4-factor model showing best overall fit. Structural equation modeling was used to determine which psychopathy factors predicted 6-month follow-up of inpatient aggression. The 2-, 3-, and 4-factor models, respectively, accounted for 16%.27%. and 3l% of the variance in aggression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychopathy in a noninstitutional sample: Differences in primary and secondary subtypes.

Early theoretical conceptualizations suggest psychopathy is a heterogeneous construct whereby psychopathic individuals are found in diverse populations. The current study examined male and female psychopathy subtypes in a large sample of undergraduate students (n = 1229). Model-based cluster analysis of the Psychopathic Personality Inventory-Short Form (PPI-SF) revealed two clusters in both male and female students. In males, the primary subtype evidenced greater psychopathic personality traits (i.e., Social Potency, Fearlessness, and Impulsive Nonconformity) and lower anxiety (i.e., higher Stress Immunity), whereas the secondary subtype displayed fewer psychopathic personality traits (i.e., Machiavellian Egocentricity and Blame Externalization) and higher anxiety (i.e., lower Stress Immunity). In females, the primary subtype exhibited higher scores across all PPI-SF subscales and lower anxiety whereas the secondary subtype reported lower PPI-SF subscale scores and higher anxiety. Across a diverse array of personality, affective, and behavioral external correlates, differences between the subtypes and with nonpsychopaths emerged. Implications for psychopathy in noninstitutional populations with respect to theory, research, and gender are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Changes in Young People's Sexual Behavior and Attitudes, 1943-1999: A Cross-Temporal Meta-Analysis.

A cross-temporal meta-analysis of 530 studies (N = 269,649) showed that young people's sexual attitudes and behavior changed substantially between 1943 and 1999, with the largest shifts occurring among girls and young women. Both young men and women became more sexually active over time, as measured by age at first intercourse (decreasing from 19 to 15 years among young women) and percentage sexually active (increasing from 13% to 47% among young women). Attitudes toward premarital intercourse became more lenient, with approval increasing from 12% to 73% among young women and from 40% to 79% among young men. Feelings of sexual guilt decreased. The correlation between attitudes and behaviors was stronger among young women. These data support theories positing that culture has a larger effect on women's sexuality.

Preventing Disruptive Behavior in Elementary Schoolchildren: Impact of a Universal Classroom-Based Intervention.

A population-based, randomized universal classroom intervention trial for the prevention of disruptive behavior (i.e., attention-deficit/hyperactivity problems, oppositional defiant problems, and conduct problems) is described. Impact on developmental trajectories in young elementary schoolchildren was studied. Three trajectories were identified in children with high, intermediate, or low levels of problems on all 3 disruptive behaviors at baseline. The intervention had a positive impact on the development of all disruptive behavior problems in children with intermediate levels of these problems at baseline. Effect sizes of mean difference at outcome were medium or small. In children with the highest levels of disruptive behavior at baseline, a positive impact of the intervention was found for conduct problems.

The reliability and validity of the Psychopathy Checklist: Youth Version (PCL:YV) in nonincarcerated adolescent males.

Current knowledge about the validity of the psychopathy syndrome in youth is limited largely to studies relying on parent-teacher rating scales or slight modifications of adult measures. Recently, the Psychopathy Checklist: Youth Version (PCL:YV) was designed for use with adolescents. However, most studies that have used this measure examined incarcerated mates and addressed only validity criteria related to antisocial behavior. We investigated the generality and construct validity of the psychopathy syndrome in an adolescent sample by assessing 115 adolescent males on probation with the PCL:YV. Reliability of measurement was high. PCL:YV ratings predicted not only antisocial behavior but also other indices of childhood psychopathology, interpersonal behaviors associated with adult psychopathy, and a lack of attachment to parents. These findings suggest that the PCL:YV identifies a syndrome in adolescence consistent with theory and research on adult males. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Disentangling the Underlying Dimensions of Psychopathy and Conduct Problems in Childhood: A Community Study.

The psychometric and predictive validity of callous-unemotional (CU) traits as an early precursor of conduct disorder and antisocial behavior were assessed. A community sample of children (4-9 years of age) were tested 12 months apart with the Antisocial Process Screening Device (APSD; P. J. Frick & R. D. Hare, 2002), a measure of early signs of psychopathy in children. Factor analysis supported the structure of the APSD. Given controversy surrounding construct overlap between psychopathy and conduct problems, a factor analysis was conducted on pooled items from the Strengths and Difficulties Questionnaire and APSD. A 5-factor solution resulted: antisocial, hyperactivity, CU traits, anxiety, and peer problems. CU traits added small but significant improvements in the 12-month prediction of antisocial behavior for boys and older girls, after controlling for Time 1 measures. These results indicate that although the dimensions of the APSD overlap with dimensions of the disruptive behavior disorders, CU traits have unique predictive validity in childhood.

A proposal for a dimensional classification system based on the shared features of the DSM-IV anxiety and mood disorders: Implications for assessment and treatment.

A wealth of evidence attests to the extensive current and lifetime diagnostic comorbidity of the Diagnostic and Statistical Manual of Mental Disorders (4th ed., DSM–IV) anxiety and mood disorders. Research has shown that the considerable cross-sectional covariation of DSM–IV emotional disorders is accounted for by common higher order dimensions such as neuroticism/behavioral inhibition (N/BI) and low positive affect/behavioral activation. Longitudinal studies indicate that the temporal covariation of these disorders can be explained by changes in N/BI and, in some cases, initial levels of N/BI are predictive of the temporal course of emotional disorders. The marked phenotypal overlap of the DSM–IV anxiety and mood disorders is a frequent source of diagnostic unreliability (e.g., temporal overlap in the shared features of generalized anxiety disorder and mood disorders, situation specificity of panic attacks in panic disorder and specific phobia). Although extant dimensional proposals may address some drawbacks associated with the DSM nosology (e.g., inadequate assessment of individual differences in disorder severity), these proposals do not reconcile key problems in current classification, such as modest reliability and high comorbidity. This article considers an alternative approach that emphasizes empirically supported common dimensions of emotional disorders over disorder-specific criteria sets. Selection and assessment of these dimensions are discussed along with how these methods could be implemented to promote more reliable and valid diagnosis, prognosis, and treatment planning. For instance, the advantages of this system are discussed in context of transdiagnostic treatment protocols that are efficaciously applied to a variety of disorders by targeting their shared features.

Tripartite dimensions of emotion in a child clinical sample: Measurement strategies and implications for clinical utility.

Several measurement strategies to assess the tripartite model of emotion in child and adolescent samples have been developed. However, no studies have comparatively examined the most suitable strategies in clinical samples of children and adolescents. This study involved the evaluation of 2 distinct measures of tripartite constructs relative to anxiety and depression criterion variables in a clinical sample of 226 children in Grades 1 through 12. Results indicated that the measures performed similarly overall, but some differences were pronounced enough to suggest that the measures indexed slightly different aspects of the same constructs. These differences appear consistent with the scale design of each instrument. Implications for measurement of these constructs in future research are highlighted.

The Relationship Between Automatic Thoughts and Negative Emotions in Children and Adolescents: A Test of the Cognitive Content-Specificity Hypothesis.

The aim of this study was to test the cognitive content-specificity hypothesis in children and adolescents aged 7-16 years. Participants consisted of a community sample of 200 youth and a clinical sample of 160 youth with anxiety, depressive, or disruptive behavior disorders. Participants completed several self-report measures assessing a wide range of negative beliefs and symptoms of internalizing and externalizing problems. Multivariate analyses examining the interrelationships between beliefs and noncognitive symptoms revealed that thoughts on loss or personal failure were the strongest predictors of depressive symptoms, thoughts on social threat were the strongest predictors of anxiety symptoms, and thoughts on hostility or revenge were the strongest predictors of aggression. Results showed clear evidence of cognitive-affective specificity across both internalizing and externalizing problems in youth. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
