Although online antisocial behavior has a long history, it appears to have become more widespread in recent years due to the widespread use of online social networks. Although there are established criteria and instruments assessing antisocial…

Children with symptoms of oppositional-defiant and conduct disorders (ODD/CD) pose significant challenges within educational settings. The worldwide prevalence among 6-18 year olds is 3.3% for ODD and 3.2% for CD (Canino, Polanczyk, Bauermeister, Rohde, & Frick, 2010). Students with conduct problems often display aggressive and antisocial…

Callous-unemotional (CU) traits have proven important for designating children and adolescents showing a pattern of particularly severe, stable, and aggressive antisocial behaviors (Frick, Ray, Thornton, & Kahn, 2014). Individuals with secondary CU traits represent a subpopulation that are distinguished from those with primary CU traits by…

Background: Conduct disorder (CD) in female adolescents is associated with a range of negative outcomes, including teenage pregnancy and antisocial personality disorder. Although recent studies have documented changes in brain structure and function in male adolescents with CD, there have been no neuroimaging studies of female adolescents with CD.…

Objective: The Psychopathy Checklist-Revised (PCL-R; Hare, 1991, 2003) is often used to assess risk of violence, perhaps based on the assumption that it captures emotionally detached individuals who are driven to prey upon others. This study is designed to assess the relation between (a) core interpersonal and affective traits of psychopathy and…

Although children with attention-deficit/hyperactivity disorder (ADHD) are at risk for impulsive, health-endangering behavior, few studies have examined nonsubstance, use-related risk-taking behaviors. This study examined whether adolescents and young adults with ADHD histories were more likely than those without ADHD histories to report frequent…

This article summarizes the empirical studies showing pathways in the development of externalizing and delinquent behaviors. Pathways are defined as the orderly temporal development between more than two problem behaviors. The paper addresses the following questions: (1) What are the developmental pathways between different diagnoses of Disruptive…

The purpose of this article was to explore the complex issues surrounding the behaviors exhibited by students who have Narcissistic Personality Disorder (NPD) and the role the disorder may play in school violence. Students with NPD are often characterized by arrogance, grandiosity, and self-importance; a preoccupation with fantasies of success and…

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…

Use of anabolic steroids is believed to increase the odds of violent antisocial behavior, thus posing risks to consumers and the general public. Some research shows the danger of steroids in inducing severe adverse psychiatric effects. Certain lawyers use this abuse to plead insanity for their clients. (SM)

Background: A sample of community-based service users with intellectual disability (ID) was re-examined after 5 years to determine the impact of a diagnosis of personality disorder (PD). Methods: Seventy-five of the original 101 participants were followed up. Of these, 21 people had a PD identified during the original study. Results: Compared with…

Background: Problems associated with psychiatric diagnoses could be minimized by identifying behavioural clusters of specific psychiatric disorders. Methods: Sixty persons with intellectual disability (ID) and behavioural problems, aged 12?55 years, were assessed with standardized Indian tools for intelligence and adaptive behaviour. Clinical…

It is essential to identify childhood predictors of adult antisocial personality disorder (APD) to target early prevention. It has variously been hypothesized that APD is predicted by childhood conduct disorder (CD), attention-deficit/hyperactivity disorder (ADHD), or both disorders. To test these competing hypotheses, the authors used data from a…

This case study examines a 16.5-year-old male adolescent who engages in fire setting, severe aggression and self injurious and impulsive behaviors. He was treated with Mode Deactivation Therapy (MDT) for four months and his problem behaviors have been reduced significantly. He was previously treated with Dialectical Behavior Therapy (DBT). It…

Analyzes a broad range of data examining the relationship among basic skill development, behavior problems, and later negative social development. Results strongly corroborate assumptions that low levels of basic skills at an early age are not per se a precursor of later maladjustment. Includes statistical data and tables. (MJP)
