This study reports the results from a Swedish randomized controlled trial of a standardized behavior management intervention. The intervention targeted students with externalizing behavior in a regular education setting. First- and second-grade students (N = 100) from 38 schools were randomly assigned to either the intervention or an active comparison group. Observer, teacher, and peer ratings were collected at pretest, posttest (6 months later), and follow-up (14 months after pretest). Significant intervention effects were found on student externalizing behavior and teacher behavior management at both posttest and follow-up. The intervention effect on student externalizing behavior was mediated by change in teacher behavior. Moderating effects of demographic and classroom variables were explored, as well as the social validity of the intervention. The results are discussed in relation to cost-effectiveness and feasibility of behavioral interventions in typical school settings.
