Childhood predictors of adult criminality: are all risk factors reflected in childhood aggressiveness?

Background Early aggressive behaviour is one of the best predictors of adult criminality. Aim To assess the degree to which family background variables, parental beliefs and behaviour and child intelligence predict child aggression and adult criminality. Method Data were used from the Colombia County Longitudinal Study, a longitudinal study of 856 children in third grade in New York, in 1959–60. Adult measures of criminal behaviour, child measures taken at age eight, child peer-nominated aggression, child's peer-nominated popularity, child's IQ and parental measures at eight years were used. Results Aggressive children were less intelligent, less popular, rejected more by their parents, had parents who believed in punishment, were less identified with their parents' self-image and were less likely to express guilt. As adults, more aggressive children with parents who were less well educated, experienced more marital disharmony and who seldom attended church were most at risk for arrest. However, after the effect of early aggression was controlled, most effects disappeared and only parents having a strong belief in punishment added significantly to risk of arrest by age 30; the only fact that then reduced the risk of arrest was having parents who attended church often. Both parental authoritarianism and child IQ reduced the risk of conviction for arrested children. Discussion Level of aggression at age eight is the best predictor of criminal events over the next 22 years. A clear implication is that the risk for criminality is affected by much that happens to a boy before he is eight years old. Preventive interventions need to target risk factors that appear to influence the development of early aggression.

Developmental Issues in School-Based Aggression Prevention from a Social-Cognitive Perspective

Contemporary research on the development and prevention of aggressive behavior in childhood and adolescence emphasizes the importance of social-cognitive factors such as perceptual biases, problem-solving skills, and social-moral beliefs in the maintenance of aggression. Indeed, school-based social-cognitive intervention approaches have been identified as best practices by the Centers for Disease Control and Prevention. However, because child age is an important covariate of both intervention effectiveness and social-cognitive ability, school-based prevention program designers should keep in mind a number of issues identified through developmental research. In this paper, we review the social-cognitive model of aggressive behavior development as applied to prevention programming. We then discuss some of the ways in which the broader developmental research base can inform the design of aggression prevention programs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45098/1/10935_2005_Article_5.pd

Proximal Peer-Level Effects of a Small-Group Selected Prevention on Aggression in Elementary School Children: An Investigation of the Peer Contagion Hypothesis

Examined peer contagion in small group, selected prevention programming over one school year. Participants were boys and girls in grades 3 (46 groups, 285 students) and 6 (36 groups, 219 students) attending school in low-resource, inner city communities or moderate resource urban communities. Three-level hierarchical linear modeling (observations within individuals within groups) indicated that individual change in aggression over time related to the average aggression of others in the intervention group. The individual child was “pulled” toward peers’ mean level of aggression; so the intervention appeared to reduce aggression for those high on aggression, and to make those low on aggression more aggressive. Effects appeared to be magnified in either direction when the child was more discrepant from his or her peers. From these results we derive a principle of “discrepancy-proportional peer-influence” for small group intervention, and discuss the implications of this for aggregating aggressive children in small group programs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44593/1/10802_2005_Article_3568.pd

Teachers' self-efficacy, perceived effectiveness beliefs, and reported use of cognitive-behavioral approaches to bullying among pupils: Effects of in-service training with the I DECIDE program.

Despite the promise of being effective in tacking bullying and conduct disorder, cognitive-behavioral (C-B) interventions are underused by teachers. Little detailed information exists as to why this is the case. The current study with junior school teachers in the U.K. (N = 249) confirmed this low reported usage and showed that while teachers tended to believe that C-B approaches would be effective, most held rather low self-efficacy beliefs. Attending a workshop on a specific C-B approach, the I DECIDE program had positive effects on perceived effectiveness and self-efficacy beliefs, and longer durations of training (3 days) were more beneficial than shorter durations (half/1 day). In line with outcome-expectancy theory and the theory of planned behavior, self-efficacy and duration of training predicted an increase in reported usage of I DECIDE across an 8-month period, and self-efficacy fully mediated the association between duration of training and increase in reported usage. The implications of these findings for overcoming impediments to the more widespread use of C-B approaches by teachers to tackling bullying were discussed, particularly the notion that attending training of sufficient duration coupled with a more explicit attention on fostering self-efficacy will pay dividends
