This issue of "FOCUS" discusses external validity and what rehabilitation researchers can do to help practitioners answer the question "How far can we generalize this finding-- is it applicable to other clients/patients, with different characteristics, in dissimilar settings treated by other clinicians?," which clinicians and…

This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

Several researchers have employed milieu therapy to address the communication needs of children with autism spectrum disorder (ASD). Thus, the purpose of this review is to examine milieu therapy, particularly, the environments and individuals involved in the training and the effectiveness of milieu therapy with children who have a diagnosis of ASD…

Curriculum-based measurement Reading (CBM-R) is an assessment procedure used to evaluate students' relative performance compared to peers and to evaluate their growth in reading. Within the response to intervention (RtI) model, CBM-R data are plotted in time series fashion as a means modeling individual students' response to varying levels of…

The assessment of generalization has become a priority of applied behavior analysis. The study provided a thorough assessement of the generality of a comprehensive self-control intervention designed to increase the math performance of an underachieving student in a regular elementary school classroom.

This research review concerning intervention to improve young children's social behavior and strategies for promoting generalization and maintenance of young children's social responding focuses on taking advantage of natural communities of reinforcement, training diversely, and incorporating functional mediators. Implications for interventionists…

Recent experimental research is synthesized to identify distinctive biobehavioral characteristics of Down's Syndrome persons across their lifespan. It is argued that educational and other intervention programs have not demonstrated strong gains having significant durability or generalization. Recommended is an interactionist function-structure…

The effects of social interaction skill interventions on the social behavior of four preschool children with behavioral handicaps were evaluated. Findings indicated unique effects for social skills training and contingency management intervention. Results are discussed in relation to the role of reciprocal interaction and behavioral trapping for…

This study assessed a microswitch-based program in which three request and one choice microswitches were used for two participants with multiple disabilities. Each request switch was linked to different stimulation opportunities. Both participants learned to use the microswitches very rapidly. Responding levels were high during intervention and…

Three low-achieving third-grade children were exposed to "report-do-report" correspondence training as a reinforcement program to improve academic performance. Intervention involved teaching the children to prompt praise following completing math work, in both training and classroom settings. Students also reported planned behaviors in their…

This study evaluated the "missing-item" language intervention with two moderately to severely retarded students (ages five and six) in a special class setting. The missing-item format produced effects in requests for targeted snack items and, after generalization training, a requesting repertoire that was durable and generalized across…

This paper identifies factors possibly influencing long-term effectiveness of social skills training with students having emotional or behavioral disorders. These include: lack of a sound conceptual framework, questionable social validity of target skills, controversies surrounding the nature of social skills deficits, imprecise assessment…

Review of the research literature on functional assessment-based interventions for students with or at risk for emotional and behavioral disorders identified key issues in the design of these studies. Issues included (1) an emphasis on descriptive analysis; (2) interventions employed and procedural integrity; (3) generalization and maintenance;…

This study evaluated a multicomponent treatment package with three adults having profound mental retardation who engaged in self-injurious hand mouthing. The intervention, which involved brief response interruption followed by the introduction of a preferred leisure item, was successfully implemented during both individual and small group…

High-probability requests were used to increase responsiveness to low-probability requests to initiate social interactions in three young boys with severe disabilities who were severely socially withdrawn. Increases were also found in unprompted social initiations and generalizations to a nontraining setting. Maintenance after training was also…
