Purpose: Although conversational recast treatment is generally efficacious, there are many ways in which the individual components of the treatment can be delivered. Some of these are known to enhance treatment, others appear to interfere with learning, and still others appear to have no impact at all. This study tests the potential effect of…

As evidence-based interventions are scaled, fidelity of implementation, and thus effectiveness, often wanes. Validated fidelity measures can improve researchers' ability to attribute outcomes to the intervention and help practitioners feel more confident in implementing the intervention as intended. We aim to provide a model for the validation of…

Single-case research design is a useful methodology for evaluating the presence of a functional relation between an intervention and the mathematical performance of students with a learning disability. However, a functional relation cannot be established with threats to internal validity of the design. External validity is impacted if researchers…

Social deficits are often a core area of development for students in special education, thus schools are charged with providing social skills interventions. Although many strategies are available, few schools successfully employ evidence-based interventions for students with autism and related disabilities. A way to address these concerns while…

Purpose: Parents of children on the autism spectrum enrolled in early intervention often receive coaching to address both social communication and disruptive behavior, which are the two most frequently reported concerns by parents. Intervention techniques for both are often recommended to be implemented across daily routines and require the…

Existing approaches for training paraeducators rely heavily on intensive one-to-one coaching and may not be feasible in practice. In this study, we test a tiered training model in which all paraeducators first received group training, and then coaching was provided only for the subset who did not meet performance criteria after group training.…

With the rapid increase in the diagnostic rates of autism spectrum disorder (ASD), there has been a growing need for evaluating the trends in training natural change agents to implement behavioral interventions and coming to a consensus on training procedures that are efficacious, efficient, and accessible. The purpose of this multiple manuscript…

Evidence-based practice (EBP) is the norm and expectation for providing interventions in school psychology. However, there are two major hurdles to be addressed before EBP can be a true improvement in providing educational and psychological interventions to children and families. The first challenge is that the standard of clinical research limits…

There is growing pressure to make efficacy experiments more useful. This requires attending to the twin goals of generalizing experimental results to those schools that will use the results and testing the intervention's theory of action. We show how electronic records, created naturally during the daily operation of technology-based…

The purpose of this study was to assess the impact of parent training on parent implementation of functional communication training (FCT) in the trained routine and in a novel routine. Three young children with developmental delays and their parents participated. A multiple-probe across parent-child dyads was used to evaluate the impact of parent…

This dissertation investigates ways of training adults to teach students with communication impairments to use augmentative and alternative communication (AAC) systems across a variety of environments. In addition to three stand-alone papers, it will start with an introduction and conclude with a discussion. Chapter 1 will provide the reader with…

Naturalistic behavioral interventions increase the acquisition, generalization, and maintenance of child social communication skills among children with developmental delays (DD). Teaching Assistants (TAs) are ideal interventionists for delivering social communication interventions because of the significant amount of time they spend working…

Measuring treatment fidelity is an essential step in research designed to increase the use of evidence-based practices. For parent-implemented communication interventions, measuring the implementation of the teaching and coaching provided to the parents is as critical as measuring the parents' delivery of the intervention to the child. Both levels…

Children with disabilities play less often and demonstrate fewer varied pretend play behaviors than children with typical development. A multiple-probe design was used to examine the relation between teachers' use of the system of least prompts and contingent imitation and the acquisition, maintenance, and generalization of pretend play and…

This study used a multiple probe across participants design, replicated across two interventions and counterbalanced across participant groups to examine the effects of number sense intervention and extensive practice intervention on strategy transformation when students with mathematics learning disabilities (MLD) solved basic fact problems. In…
