This article provides a reconceptualization of the role of schools in preventing antisocial behavior problems among children and youth. The U.S. Public Health Service's conceptual model of prevention, involving primary, secondary, and tertiary prevention approaches, is used as an organizing framework to illustrate how schools can deliver interventions more effectively and improve outcomes. Traditional school approaches to coping with students who are at risk and antisocial are reviewed, and the following major topics are addressed: (a) A case is made that schools can play a central, coordinating role in collaboration with families and social service agencies in addressing the challenging problems presented by antisocial students; (b) a generic intervention approach is suggested that involves reducing risk factors for antisocial behavior and enhancing protective factors; (c) a three-level approach to organizing specific interventions for achieving prevention goals and outcomes is described; and (d) recommended interventions or approaches are suggested for each prevention level (i.e., primary, secondary, tertiary). The article concludes with a discussion of some factors associated with a revised mission for schools in this domain and how these factors may impair or enhance the necessary changes required to achieve this goal.

Office discipline referrals (ODRs) are widely used by school personnel to evaluate student behavior and the behavioral climate of schools. In this article, the authors report the results of a review of the relevant literature to evaluate the validity of ODR data as indices of school-wide behavioral climate, the effects of school-wide behavioral interventions, and differing behavior support needs across schools. They used Messick's unified approach to validity by focusing on examples of evidence for empirical and ethical foundations of interpretations, uses, and social consequences of ODR measures at the school-wide level. The authors also discuss ongoing issues, study limitations, and related recommendations for interpretations and uses of ODR measures as school-wide indices, based on the existing literature.

School discipline addresses schoolwide, classroom, and individual student needs through broad prevention, targeted intervention, and development of self-discipline. Schools often respond to disruptive students with exclusionary and punitive approaches that have limited value. This article surveys three approaches to improving school discipline practices and student behavior: ecological approaches to classroom management; schoolwide positive behavioral supports; and social and emotional learning. The article examines their epistemological and empirical roots and supporting research, suggesting ways to combine approaches.

Interspersed requests are simple commands, with a high likelihood of being followed correctly, that are interspersed among instructional trials to increase the probability that a learner will attempt to perform new or difficult tasks without engaging in aggression or self-injurious behavior. This report presents two assessments of the effect of interspersed requests on aggression and self-injury during instruction. The participants were individuals with severe mental retardation who used aggression and self-injury to avoid difficult instructional situations. Results from both studies indicate that interspersed requests were effective at increasing the responsiveness of the learners to instructions and reducing levels of aggression and self-injury.

This article addresses the growing problem of antisocial behavior in schools and its impact on safety, effectiveness, and ecology. We describe the factors leading to the development of antisocial behavior in children and youth. We explore the relationship between early investment in an antisocial behavior pattern and later negative outcomes including school failure, delinquency, and violence. The article also focuses on best practices in the areas of screening and early intervention for antisocial children and youth and those who are at risk for adopting this behavior pattern. Recommendations are made regarding research-based practices, tools, and approaches in both screening and intervention. A model for integrated approaches to school-based prevention of antisocial behavior is presented and the implications of such a model are discussed.

This report provides an experimental analysis of generalized vending machine use by six moderately or severely retarded high school students. Dependent variables were training trials to criterion and performance on 10 nontrained "generalization" vending machines. A multiple-baseline design across subjects was used to compare three strategies for teaching generalized vending machine use. Training occurred with (a) a single vending machine, (b) three similar machines, or (c) three machines that sampled the range of stimulus and response variation in a defined class of vending machines. Results indicated that the third approach was the most effective method of obtaining generalized responding. Methodological implications for the experimental analysis of generalization and programmatic implications for teaching generalized behaviors are discussed.

Two studies examined the effects of a reductive treatment versus instruction-based treatments on the generalized reduction of problem behaviors. Each study involved a detailed analysis of multiple problem behaviors performed by school-aged youth with severe intellectual disabilities. The analysis examined the contrasting effects of one of two different positive intervention procedures (teaching a positive alternative behavior or providing additional teacher assistance during instruction) versus blocking and/or verbally reprimanding a problem behavior. The focus of each analysis was on the covariation of multiple problem behaviors within functional response classes. Results of the investigation indicated that when only one member of the response class was blocked, a collateral increase was observed in one or more different problem behaviors from the same response class. Alternatively, when 1 participant was taught a functionally equivalent mand response, all problem behaviors in the response class were reduced. Problem behaviors also were reduced for the remaining participant by presenting antecedent teacher assistance. Implications of the research extend to analysis of covariation within response classes and to procedures that result in generalized reduction of problem behaviors within a response class.

Research in applied behavior analysis has shaped an important technology, called functional assessment, for understanding the relationship between problem behavior and environmental events and factors. From this understanding, effective and relevant behavioral interventions have emerged. However, given the dramatic increase in the need to conduct functional assessments, efforts must focus on translating what we have learned from this research into formats and processes that can be used efficiently in applied settings. In addition, research must continue to build a technology of functional assessment that meets the full range of situations faced in our schools, homes, and communities.
