BACKGROUND Antisocial personality disorder is usually preceded by serious and persistent conduct problems starting in early childhood, and so there is little difficulty in identifying an at-risk group. AIMS To address six key areas concerning the relationship between early conduct problems and antisocial personality disorder. METHOD Review of recent research into early identification of and...

This study developed and validated the Youth Conduct Problems Scale-Rwanda (YCPS-R). Qualitative free listing (n = 74) and key informant interviews (n = 47) identified local conduct problems, which were compared to existing standardized conduct problem scales and used to develop the YCPS-R. The YCPS-R was cognitive tested by 12 youth and caregiver participants, and assessed for test-retest and ...

BACKGROUND Screen entertainment for young children has been associated with several aspects of psychosocial adjustment. Most research is from North America and focuses on television. Few longitudinal studies have compared the effects of TV and electronic games, or have investigated gender differences. PURPOSE To explore how time watching TV and playing electronic games at age 5 years each pre...

Comorbid conduct problems (CPs) and depression are observed far more often than expected by chance, which is perplexing given minimal symptom overlap. In this study, relations between parental psychopathology and children's diagnostic status were evaluated to test competing theories of comorbidity. Participants included 180 families with an 8-12-year-old child diagnosed with CPs, depression, bo...

Although there is considerable evidence that culture-related factors are associated with aggressive behavior, their effect on the development of conduct problems (CP) has been insufficiently studied. This study focused on adherence to honor code (AHC), defined by the endorsement of honor culture attitudes at the identity narrative level of personality assessment, as a mediator in the prediction...

METHOD Teachers provided ratings of callous-unemotional traits and conduct problems for 3434 twin pa...

BACKGROUND Individual differences in conduct problems arise in part from proneness to anger/frustration and poor self-regulation of behavior. However, the genetic and environmental etiology of these connections is not known. METHOD Using a twin design, we examined genetic and environmental covariation underlying the well-documented correlations between anger/frustration, poor attention regula...
