The distinction between beliefs legitimizing aggression and deviant processing of social cues: testing measurement validity and the hypothesis that biased processing mediates the effects of beliefs on aggression. Conduct Problems Prevention Research Group.

In 2 studies the authors examined knowledge and social information-processing mechanisms as 2 distinct sources of influence on child aggression. Data were collected from 387 boys and girls of diverse ethnicity in 3 successive years. In Study 1, confirmatory factor analyses demonstrated the discriminant validity of the knowledge construct of aggression beliefs and the processing constructs of hostile intent attributions, accessing of aggressive responses, and positive evaluation of aggressive outcomes. In Study 2, structural equation modeling analyses were used to test the mediation hypothesis that aggression beliefs would influence child aggression through the effects of deviant processing. A stronger belief that aggressive retaliation is acceptable predicted more deviant processing 1 year later and more aggression 2 years later. However, this latter effect was substantially accounted for by the intervening effects of deviant processing on aggression.

Attributions for social failure and aggression in incarcerated delinquent youth.

While a variety of cognitive deficits and biases have been found to characterize aggressive and delinquent children and youth, very little attention has focused on determining whether aggressive youth also display deviant attributional beliefs in response to social failure. Research in the more impersonal cognitive domains such as achievement has shown attributions for failure to be potent determinants of both affective reactions and subsequent responding. Thus, the present study was designed to investigate whether specific attributional patterns following social failure may also relate to aggressive behavior. The aim of this study was to determine the relation between the level of self-reported physical aggression and specific attributional patterns following hypothetical social failure in a sample of incarcerated delinquent males. While the general hypotheses were that increased aggressiveness would be related to a greater tendency to endorse attributions for social failure that are external, stable, and controllable, only the hypothesis with regard to controllability was supported. The findings are discussed in terms of the relation between cognition and aggression in delinquent youth.

Discipline responses: influences of parents' socioeconomic status, ethnicity, beliefs about parenting, stress, and cognitive-emotional processes.

Direct and indirect precursors to parents' harsh discipline responses to hypothetical vignettes about child misbehavior were studied with data from 978 parents (59% mothers; 82% European American and 16% African American) of 585 kindergarten-aged children. SEM analyses showed that parents' beliefs about spanking and child aggression and family stress mediated a negative relation between socioeconomic status and discipline. In turn, perception of the child and cognitive-emotional processes (hostile attributions, emotional upset, worry about child's future, available alternative disciplinary strategies, and available preventive strategies) mediated the effect of stress on discipline. Similar relations between ethnicity and discipline were found (African Americans reported harsher discipline), especially among low-income parents. Societally based experiences may lead some parents to rely on accessible and coherent goals in their discipline, whereas others are more reactive.

Prevalence of asthma and wheezing in public schoolchildren: association with maternal smoking during pregnancy.

BACKGROUND: Asthma is the most common chronic disease in childhood. The prevalence of asthma is especially high in inner city children. The occurrence of asthma may be associated with many environmental factors, including involuntary exposure to maternal smoking. OBJECTIVES: This study reports prevalence of asthma and wheezing in a sample of public school students in Chicago and examines the association between maternal smoking during pregnancy and childhood asthma. METHODS: A total of 705 fifth grade students from 13 public schools participated in the study. A slightly modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was administered in classrooms to assess students' wheezing and asthma prevalence. RESULTS: Overall, 34.5% of children reported ever wheezing, 28.9% reported wheezing in the past year, 21.1% reported exercise-related wheezing in the past year, 23.6% reported physician-diagnosed asthma, 16.1% reported taking asthma or wheezing medication in the past 2 weeks, and 15.2% reported visiting emergency rooms for treatment of asthma in the past year. After adjusting for confounding variables in a logistic model, maternal smoking during pregnancy was significantly associated with children's asthma (adjusted odds ratio = 1.9; 95% confidence interval: 1.1 to 3.5). CONCLUSIONS: This study reports high prevalence of asthma and wheezing among the students and suggests that maternal smoking during pregnancy may increase the risk of asthma in children.
