Children who show elevated levels of indirect aggression (IA) from childhood to adolescence are at increased risks of experiencing detrimental outcomes. Some studies suggest that psychopathic traits could act as a predisposing vulnerability in the development of IA, but the contributions of all three dimensions of psychopathic traits in explaining…

Youth with greater levels of narcissism face a wide array of difficulties in interactions with others. However, there exists a curious lack of research on their close relationships, such as friendships. In this study, we examined associations between narcissism and friendship features over time. Participants were 261 eighth and ninth graders (112…

A family systems framework guided our investigation of self-injurious behavior (SIB) in adolescents. As part of a larger study, we collected data examining SIB and family functioning from 29 adolescents (M[subscript age] = 15.66) and their caregivers. These adolescents with traits of borderline personality disorder were seeking counseling from…

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…

Background: Although prior studies have shown that detained females are marked by significant adverse circumstances, little is known about their adult outcomes. Method: Prospective follow-up study of 184 (80.4% of original sample of 229) detained adolescent females who were reassessed 4.5 SD = 0.6) years later in young adulthood (mean age = 20.0,…

Objective: The identification of reliable predictors of course in major depressive disorder (MDD) has been difficult. Evidence suggests that the co-occurrence of personality pathology is associated with longer time to MDD remission. Interpersonal pathoplasticity, the mutually influencing nonetiological relationship between psychopathology and…

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…

An overview of the history of adolescent runaway behavior indicates that it has become a social and psychological problem of significant proportions. This study investigated the use of a personality measure that was hypothesized to be representative of a cluster of behaviors associated with running away. The study also sought to determine a…

Examined the prevalence of eligibility for educational services for serious emotional disturbance (SED) among incarcerated youths, as well as how this designation relates to offender type. Logistic regression was used to understand whether youths with SED designations were likely to be incarcerated for violent offenses. SED status was not…

The potential role of social support for the adolescent offspring of psychiatric patients has hitherto not been examined. We examined whether the adolescent's level of psychiatric symptoms is dependent on the content and the function of social support (whether direct or moderating), controlling for perceived stress. In a cross-sectional design, 40…

This report discusses the outcomes of a study that examined a hypothesis about the acquisition of behavioral inhibitions offered by Hans Eysenck, which suggests that what is often described as morality or conscience is acquired through conditioning experiences to which individuals respond differently according to their temperament-based…

This paper examines antisocial behavior in children and youth in relation to the biosocial personality theory of Hans Eysenck. It explains Eysenck's theory, which includes a significant role for biological factors in the development of antisocial behavior. The theory holds that three temperament traits--Psychoticism (P), Extroversion (E), and…

Evaluated the longitudinal implications of age-18 dysphoric mood in 23-year olds using a multidata, multi informant design. Findings indicated that adolescent dysphoric mood was an important predictor of psychological distress in young adults, especially in young adult women, for whom the prospective correlations of adolescent dysphoria were more…

This paper discusses the outcomes of a study that examined Hans Eysenck's antisocial behavioral hypothesis (ASB). Eysenck's theory of personality has three temperament-based traits: Psychoticism (P), Extraversion (E), and Neuroticism (N). His ASB hypothesis predicts that individuals high on P, E, and N with poor socialization are at the greatest…
