In science in general and in the context of single-case experimental designs, replication of the effects of the intervention within and/or across participants or experiments is crucial for establishing causality and for assessing the generality of the intervention effect. Specific developments and proposals for assessing whether an effect has been…

The use of behavioral skills training (BST) to educate 3 adolescent boys on the risks of lighters and fire setting was evaluated using in situ assessment in a school setting. Two participants had a history of fire setting. After training, all participants adhered to established rules: (a) avoid a deactivated lighter, (b) leave the training area,…

This article demonstrates the impact of functional analysis methodology on clinical work, by describing the evolution of assessment procedures based on "brief functional analysis" methodology at University of Iowa outpatient clinics. It discusses the positive impact functional analysis has had on outpatient clinic assessment as well as…

Principles of statistical process control are applied to a clinical setting through the use of control charts to detect changes, as part of treatment planning and clinical decision-making processes. The logic of control chart analysis is derived from principles of statistical inference. Sample charts offer examples of evaluating baselines and…

A case study of an elementary school child with emotional and behavioral problems illustrates a process of descriptive assessment, functional assessment, and assessment-based intervention. The descriptive information generated hypotheses about variables maintaining the problem behavior which were then tested in the classroom environment.…

The article reports on ways in which the Preparation through Responsive Educational Programs (PREP) project developed and conducted process and outcome assessment in a behavioral program for junior high students with behavior and learning problems. (Author/DLS)

Statistical process control (SPC), which employs simple statistical tools and problem-solving techniques such as histograms, control charts, flow charts, and Pareto charts to implement continual product improvement procedures, can be incorporated into human service organizations. Examples illustrate use of SPC procedures to analyze behavioral data…
