For students with severe or complex challenging behavior, incorporating hypothesis testing as a component of functional behavior assessment (FBA) is often warranted. Several hypothesis testing strategies (i.e., functional analysis, antecedent analysis, concurrent operant analysis) can confirm whether and how features of a student's environment…

The purposes of this paper are to (a) propose an operational standard for defining a "practice," (b) encourage development of professional standards for visual and statistical analysis of single-case research, and (c) propose a standard for using single-case research results to identify practices that are "evidence-based." These topics are not new…

Although functional behavior assessment (FBA) has been widely recognized as a promising practice for providing proactive interventions with students exhibiting challenging behaviors in typical schools, questions persist as to how FBA should best be trained and used in such public settings. Debate has balanced the issue of what is practical for…

We describe the historic and current use of brief experimental analysis procedures in outpatient clinic and home settings. We discuss some applications of the designs and suggest design modifications for improving internal validity. We describe our application of the designs to longitudinal, in-home programs for children with severe behavior…

Since the reauthorization of IDEA (1997), the use of functional assessments to examine factors that are related to students' challenging behaviors has gained increasing attention in the literature. Over the past five years, several groups of investigators have conducted systematic analyses of the current status of the use of functional assessment…
