The dark core of personality is a recent construct that encompasses the malevolent, antagonistic, and aversive side of human nature that represents the common inner core of dark personality traits. The aim of the present study is to develop a short, multidimensional, and invariant version of the dark core of personality D70 measure. Two samples of…

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were…

This work evaluated the cross-sectional and longitudinal (i.e., over four months) impact of attachment to mother, father, and peers on three psychopathic traits (i.e., grandiose-manipulative, callous-unemotional, and impulsive-irresponsible) using a community adolescent sample, and if that impact was differentiated by gender. Though there is…

This research examined whether following social and physical aggression trajectories across Grades 3-12 predicted psychological maladjustment. Teachers rated participants' (n = 287, 138 boys) aggressive behavior at the end of each school year. Following the 12th grade, psychosocial outcomes were measured: rule-breaking behaviors, internalizing…

Antisocial behavior and school aggression in youth has been linked with affective, interpersonal, self-attributional, and behavioral characteristics; these traits have often been associated with psychopathic behaviors among adults. Psychopathic traits were examined in nonclinically-referred youth exhibiting antisocial and aggressive behavior.…

This study had three primary goals: to explore the relationship between narcissism, participant roles, and aggression; to examine the role of gender as a moderating influence on narcissism-based aggression; and to examine how these variables work together to influence aggressive outcomes in a sample of aggressive middle and high school students.…

Objective: To investigate the relative importance of ADHD symptoms, mood instability, and antisocial personality disorder traits in predicting self-reported offending. Method: A total of 295 Icelandic students completed two scales of offending behavior and measures of ADHD symptoms, mood instability, and antisocial personality traits. Results:…

In this study, self-report student surveys on early childhood maltreatment, attachment styles, alcohol expectancies, and narcissistic personality traits are examined to determine their influence on stalking behavior. Two subtypes of stalking were measured using Spitzberg and Cupach's (2008) Obsessive Relational Intrusion: cyber stalking (one…

Many personality assessment inventories provide gender-specific norms to allow comparison of an individual's standing relative to others of the same gender. In some cases, this means that an identical raw score produces standardized scores that differ notably depending on whether the respondent is male or female. Thus, an important question is…

This study examined the development of antisocial personality problems (APP) in young adulthood from disruptive behaviors and internalizing problems in childhood and adolescence. Parent ratings of 507 children's (aged 6-8 years) symptoms of attention deficit hyperactivity disorder, oppositional defiant disorder, and anxiety, were linked to…

This study tested differences in personality traits measured by the Multidimensional Personality Questionnaire (MPQ) in a community sample of adolescents with definite or probable conduct disorder (CD) diagnoses that did not progress to a diagnosis of antisocial personality disorder (ASPD) by early adulthood (n=43), those with definite or probable…

This study evaluated the structural reliability, construct-related validity, and cultural validity generalization of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in a sample of more than 560 male and female Swedish forensic psychiatric treatment patients, forensic evaluation patients, and criminal offenders. Structural reliability…

Current prevalence rates of Conduct Disorder (CD) in girls may be an underestimate due to inappropriate diagnostic criteria, biased perceptions by those responsible for reporting problematic behavior, and differential social constraints for each gender. Relatively few published studies of CD and related behaviors in girls exist. Available evidence…

Background: This study aimed to identify personality features characterizing adolescent girls and boys with borderline personality disorder (BPD) and to see whether meaningful patterns of heterogeneity exist among adolescents diagnosed with the disorder. Methods: Two hundred and ninety-four randomly selected doctoral-level clinicians described…

A review is made of female intimate abuse. It is concluded that females are as abusive as males in intimate relationships according to survey and epidemiological studies. This is especially so for younger "cohort" community samples followed longitudinally. Predictors of intimate violence with women appear to be similar to those of men; including…
