Non-suicidal self-injury (NSSI) continues to be an important problem in adolescents, and it was aimed to investigate the relationship between suicide probability, cyberbullying, impulsivity, and aggression with NSSI history in the adolescent clinical population on the basis of gender. 267 adolescents with a history of NSSI and 210 without were…

Children who exhibit inattention (IA) and hyperactivity-impulsivity (HI), symptoms often indicative of attention-deficit/hyperactivity disorder (ADHD), have notable social impairments. We investigated whether IA and HI are directly connected to peer difficulties or indirectly connected through their known association with other problem behaviors.…

It is unknown whether sluggish cognitive tempo (SCT) is prospectively associated with depression in adolescence, and possible processes linking SCT to depression remain unexamined. Using a longitudinal study with three timepoints over a two-year period, the current study tested the indirect effects of SCT on depression via peer victimization,…

In a previous study, reactive criminal thinking or cognitive impulsivity mediated the relationship between parental knowledge and delinquency. This study sought to determine whether cognitive impulsivity also mediated the relationship between parental knowledge and childhood aggression. A path analysis was performed on a sample of 438 early…

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.…

The present study investigated externalizing and internalizing behaviours in Greek (n = 599), Russian (n = 596), Indian (n = 571), and Chinese (n = 376) 7- to 12-year-old children. The Fairy Tale Test was used to measure impulsive and motivated aggression, fear of aggression, anxiety, and depression. The results indicated culture-specific patterns…

The current study investigated the patterns of aggressive behavior displayed in a sample of 282 students in the 4th through 7th grades (M age = 11.28; SD = 1.82). Using cluster analyses, two distinct patterns of physical aggression emerged for both boys and girls with one aggressive cluster showing mild levels of reactive aggression and one group…

The goal of this study is twofold: (1) to assess brain anatomical differences between children meeting diagnostic criteria for oppositional defiant disorder (ODD) and healthy controls, and (2) to investigate whether morphological brain characteristics associated with ODD differ in boys and girls. Eight-year-old participants (N = 38) were scanned…

Men are overrepresented in socially problematic behaviors, such as aggression and criminal behavior, which have been linked to impulsivity. Our review of impulsivity is organized around the tripartite theoretical distinction between reward hypersensitivity, punishment hyposensitivity, and inadequate effortful control. Drawing on evolutionary,…

If a mother is stressed or anxious while pregnant her child is more likely to show a range of symptoms such as those of attention deficit hyperactivity disorder, conduct disorder, aggression or anxiety. While there remains some debate about what proportion of these effects are due to the prenatal or the postnatal environment, and the role of…

This study examined the structural relations of preadolescents' inattention and hyperactivity/impulsivity, aggressive and prosocial behaviors, and peer functioning. There were 739 fourth (n = 239) and fifth (n = 500) graders (52.23% boys) in Taiwan who participated in this study. Preadolescents' inattention and hyperactivity/impulsivity were…

The purpose of this study was to extend the current literature on forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of participants' cognitions and beliefs about aggressive behavior. Participants included an ethnically diverse group of emerging adults (N = 165; M = 19.05 years; SD = 1.55) and completed a battery of…

This study presents evidence on the reliability and construct validity of the Dutch version of the Youth Psychopathic traits Inventory (YPI), a self-report instrument for psychopathic traits in adolescent boys and girls. In a sample of 776 Dutch non-referred adolescents, the YPI was found to have good internal consistency. Furthermore, exploratory…

The authors examined the association between alcohol consumption and aggression from a personality trait perspective with 92 self-identified Hispanic college students.
