This paper is on the influences of the classroom context on the course and malleability of aggressive behavior from entrance into first grade through the transition into middle school. Nineteen public elementary schools participated in developmental epidemiologically based preventive trials in first and second grades, one of which was directed at reducing aggressive, disruptive behavior. At the start of first grade, schools and teachers were randomly assigned to intervention or control conditions. Children within each school were assigned sequentially to classrooms from alphabetized lists, followed by checking to insure balanced assignment based on kindergarten behavior. Despite these procedures, by the end of first quarter, classrooms within schools differed markedly in levels of aggressive behavior. Children were followed through sixth grade, where their aggressive behavior was rated by middle school teachers. Strong interactive effects were found on the risk of being highly aggressive in middle school between the level of aggressive behavior in the first grade classrooms and each boy's own level of aggressive, disruptive behavior in first grade. The more aggressive first grade boys who were in higher aggressive first grade classrooms were at markedly increased risk, compared both to the median first grade boys, and compared to aggressive males in lower aggressive first grade classrooms. Boys were already behaving more aggressively than girls in first grade; and no similar classroom aggression effect was found among girls, although girls' own aggressive behavior did place them at increased risk. The preventive intervention effect, already reported elsewhere to reduce aggressive behavior among the more aggressive males, appeared to do so by reducing high levels of classroom aggression. First grade males' own poverty level was associated with higher risk of being more aggressive, disruptive in first grade, and thereby increased their vulnerability to classroom level of aggression. Both boys and girls in schools in poor communities were at increased risk of being highly aggressive in middle school regardless of their levels of aggressive behavior in first grade. These results are discussed in terms of life course/social field theory as applied to the role of contextual influences on the development and etiology of severe aggressive behavior.

In this article, we examine the impact of two universal, first-grade preventive interventions on the prevalence of conduct problems and disorder and mental health service need and use in early adolescence. The classroom-centered (CC) intervention was designed to reduce the risk for later conduct problems and disorder by enhancing teachers' behavior management in first grade, whereas the Family-School Partnership (FSP) intervention targeted improvement in parent-teacher communication and parents' child behavior management strategies. At Grade 6, or age 12, CC and FSP intervention children received significantly lower ratings from their teachers for conduct problems than control children. CC and FSP children were also significantly less likely than control children to meet diagnostic criteria for Conduct Disorder and to have been suspended from school in the last year. In addition, the CC intervention was associated with significantly lower rates of child mental health service need and utilization. Overall, the CC intervention appeared to be the more effective of the two in reducing the prevalence of conduct problems and disorder at age 12 and in reducing mental health service need and utilization. Nevertheless, future studies may show that the combination of CC and FSP interventions produces additive or even synergistic effects.

The present study addressed two specific questions:(1) Are there differences in parenting behaviors between anxious and non-anxious mothers? and (2) Are parenting behaviors within these two groups associated with adverse outcomes in children (i.e., internalizing and externalizing symptoms)? The above questions were examined concurrently (when children were in first grade) and at a six-year follow-up among a predominately African American community-based high-risk sample. Twenty-five anxious and matched non-anxious (N = 50) mothers were videotaped with their children (mean age 5.8 years) engaging in a challenging task. Blind raters coded parent behaviors. Parents and children completed measures of anxiety and/or externalizing symptoms at both time points. Contrary to expectations, results indicated no group differences in parenting behaviors in the first grade and no relation be-Golda S. Ginsburg, PhD, Rachel L.

At the six-year follow-up, however, higher levels of criticism and lower levels of granting of autonomy were significantly related to higher anxiety (but not externalizing) symptoms in children of anxious parents. Findings are discussed in the context of existing developmental models of childhood anxiety and suggest that the interaction of parental anxiety and parenting behavior may increase children's risk for anxiety disorders.

It is generally believed that prior to the middle to late elementary school years children's reports of anxious symptoms represent nothing more than transient developmental phenomena. In light of the limited empirical study of this issue and its import to the allocation of mental health resources, the present study seeks to provide empirical evidence of the significance of anxious symptoms in children younger than 7. Specifically, utilizing an epidemiologically defined population of 1197 first-grade children, followed longitudinally from the fall to spring of first grade, we examine the stability, prevalence and caseness of children's self-reports of anxious symptoms. Self-reported anxious symptoms proved relatively stable over 4-month test-retest interval. In addition, they appeared to have a significant impact on academic functioning in terms of reading achievement. These findings on stability, caseness, and prevalence suggest children's self-reported anxious symptoms in the early elementary school years may have clinical significance. However, further study is necessary before firm conclusions can be drawn.
