Identifying positive behavioral interventions for students who display disruptive behavior in the classroom has become a critical issue for schools due to the high frequency of these behaviors and recent changes in legislative requirements. To address this issue, the present study investigated the utility of brief experimental analysis approach as a means to identify the most efficient and effective interventions for three students displaying problem behaviors in the classroom. By using a multi-element design, the brief experimental analysis was conducted by randomly applying interventions for three common functions of problem behavior in the classroom: teacher attention, peer attention, and escape from task demand. Then, the effects of the most efficient and effective intervention on on-task, disruptive, and work completion behaviors were compared relative to a baseline condition over time. There were individual differences in responses to the intervention, but all students responded to at least one treatment. Further, an extended analysis of the alternative baseline conditions using a BAB design was applied that included a treatment phase with the hypothesized efficient and effective treatment and a baseline phase. Results showed that selected interventions decreased disruptive behavior and increased on-task and work completion for all three participants over time relative to baseline.

Functional Analysis is a widely used and effective tool for the assessment of challenging behavior. However, there are several practical issues associated with analogue functional analysis, including the reinforcement of challenging behavior and the extended duration of the assessment process. These issues have been addressed in several modified functional analysis models, including the brief functional analysis. The brief functional analysis allows practitioners and researchers to complete an assessment of challenging behavior within a 90-minute period, thus addressing the practical issue of extended duration. It does not, however, address the potential issues associated with the reinforcement of challenging behavior. The current study evaluated the efficacy of three modified functional analysis methods, including a brief antecedent-based analysis (A-B), a brief latency-based analysis, and a brief functional analysis (A-B-C). Results from each assessment were compared and high levels of correspondence was observed between the respective assessment models. Results are discusses in terms of the relative strengths and limitations of each of the models. / text
