Background: Oppositional Defiant Disorder (ODD) appears more prevalent among children with intellectual disabilities (ID) as compared to children with typical development. However, it remains unclear what drives this difference. Methods: Data from 70 youth with typical development (TD) and 20 youth with ID were drawn from (The Collaborative Family…

Objective: To conduct a pilot test of the validity of using empirically derived personality types to characterize eating disorder (ED) risk in college students and resolve discrepancies regarding the role of perfectionism and obsessive-compulsive disorder (OCD) symptoms. Participants: Man and woman undergraduate students (N = 169) at a small,…

Child and youth conduct problems are known to be a heterogeneous category that implies different factors and processes. The current study aims to analyze whether the early manifestation of psychopathic traits designates a group of children with severe, pervasive and persistent conduct problems. To this end, cluster analysis was conducted in a…

Background: The presence of a large cavum septum pellucidum (CSP) has been previously associated with antisocial behavior/psychopathic traits in an adult community sample. Aims: The current study investigated the relationship between a large CSP and symptom severity in disruptive behavior disorders (DBD; conduct disorder and oppositional defiant…

Externalising behaviours such as substance misuse (SM) and conduct disorder (CD) symptoms highly co-ocurr in adolescence. While disinhibited personality traits have been consistently linked to externalising behaviours there is evidence that these traits may relate differentially to SM and CD. The current study aimed to assess whether this was the…

Background: Callous and unemotional (CU) traits might usefully subtype DSM-IV conduct disorder (CD). We investigate this hypothesis in a large, nationally representative sample of 5-16-year-olds. We also examine the characteristics of children with high CU traits but without CD. Methods: Data come from the 2004 British Child and Adolescent Mental…

Objective: Oppositional defiant disorder (ODD) is classified as a disruptive disorder, but shows a wide range of associations with other psychopathology, including internalizing problems. The reasons for these associations are unclear. Here we test the hypothesis that two distinct early temperamental precursors--emotionality and activity--underlie…

The Youth Psychopathy traits Inventory (YPI) is a newly developed self-report measure of psychopathy. There are no studies looking at the validity of this measure in UK samples. We assessed 115 male adolescents (mean age 16.22 years) with DSM-IV conduct disorder on a range of measures including the YPI, Child Behaviour Checklist (CBCL) and the…

Examines the incidence of psychopathy among an alcoholic-offender population (N=128) and compares psychopathic and non-psychopathic alcoholics in relation to childhood history, demographics, alcohol dependence, violence, and suicide. Results indicate that 20% of offenders could be classified as psychopaths. These persons were more alcohol…

Hospitalized female patients with borderline personality disorder were assessed for Axis II disorders by the Structured Clinical Inventory for the Diagnostic and Statistical Manual of Mental Disorders (SCID-II) and for personality traits with the NEO Personality Inventory. The relationship of results to social adjustment and the utility of…

Evaluated internalized and externalized anger in adolescent psychiatric inpatients. Results indicated that internalized anger led to depression and feelings of hopelessness and increased chances of suicide attempts. In contrast, externalized anger was related to alcohol-related problems. Thus, different modes of anger expression appear to be…

This study examined the influence of diagnostic criteria and diagnostic labels for psychopathy or conduct disorder on judicial decisions. A national sample of judges (N = 326) rendered hypothetical dispositions based on 1 of 12 mock psychological evaluations. The evaluations varied the presence of 2 sets of diagnostic criteria (antisocial…

This review discusses conceptual issues in relating temperament to psychopathology, including the disputed relation of temperament to personality in children. A potential integrative framework is discussed that links trait and biological markers of temperament (reactive, incentive-response tendencies) with regulatory processes. This framework is…

This study compared 136 second, third, and fourth graders considered to be at high, moderate, and low risk of behavior disorders on several variables. The Critical Events Index was used; primary differences among the groups were on indicators of social competence and externalizing behaviors. (CR)

Research on factors which contribute to the development of antisocial personality disorder is reviewed. Methodological issues are critiqued, including major assessment instruments and frequently used research designs. Factors which current research indicates might lead to the continuation of antisocial behavior from childhood into adulthood are…
