Predicting adult offending behavior for individuals who experienced a traumatic brain injury during childhood.

Objectives: To examine whether individuals who experienced a childhood traumatic brain injury (TBI) are at increased risk for subsequent offending behavior, to identify the emotional characteristics of adults who experienced childhood TBI, and to examine whether these predict offending behavior.

Participants: Individuals from the Canterbury region who had experienced a childhood (<18 years of age) injury event and were now 18 years or older and more than 5 years postinjury (between 18 and 30 years of age). Three groups were formed: (1) moderate/severe TBI (n = 62); (2) mild TBI (n = 58); and (3) fracture control group (n = 38).

Relationship between psychopathy and indirect aggression use in a noncriminal population.

Psychopathy has long been associated with increased use of direct aggression and violence, especially among male inmates. Little research has, of yet, considered the relation between psychopathy and indirect forms of aggression. The current research sought to investigate the relationship between psychopathy and indirect aggression in a noncriminal sample.

The construction and validation of a new scale for measuring emotional response style in adolescents.

Background: Research on children's emotional behaviour has been hampered by the lack of psychometric assessment scales. The present study reports on the construction and validation of a new self-report instrument to measure the emotional response styles of adolescents.

Method: Exploratory and confirmatory factor analyses were carried out on the responses of three samples of adolescents aged between 11 and 14 years (total = 609) to an item pool derived from a scenario study.
