Implementation of evidence-based practices for autistic students must be informed by robust research literature. Randomized-controlled trials (RCTs) are often considered a "gold standard" methodology for determining the effectiveness of interventions. However, the complex nature of schools presents challenges for implementing successful…

In this dissertation, I investigated the impact of the involvement of students with disabilities in the ASPIRE intervention program and examined the relationship between student involvement in the ASPIRE program and academic performance and growth. To do so, first, I outlined how I built my perspective for this study in the areas of transition,…

Engagement behaviors are crucial for school success and are often targeted for improvement in school-based interventions. It may be helpful for both researchers and school-based practitioners to understand the likely impacts of interventions on engagement behaviors (e.g., to understand the extent to which engagement behaviors might change with…

The rapid growth of inclusive higher education opportunities for young adults with intellectual and developmental disabilities (IDD) has contributed to improvements in students' academics, employment, social, and independent living outcomes. However, many college programs lack a focus on functional literacy, a critical skill for success in…

Bullying is a public health priority but to date, there is a lack of evidence-based anti-bullying programmes or interventions designed for use in special schools. KiVa is a successful anti-bullying programme for mainstream schools currently used in 23 countries. This brief paper outlines the co-development and adaptation of two KiVa lessons into…

Special education researchers have for decades emphasized the importance of intervention effectiveness and procedural fidelity, but relatively little attention has been directed toward understanding intervention intensity. This review focused on extracting details of intervention intensity as reported in peer-reviewed studies of scripting and…

At the onset of the COVID-19 pandemic, schools across the United States transitioned to some form of emergency remote instruction. Preliminary research suggests that special education services may have been disjointed and many caregivers assumed a primary role in service provision during emergency remote instruction. To extend this work with a…

Background: Key Word Signing (KWS) is one system that can be used to support the communication needs of children with Down syndrome (DS) who attend mainstream school. The success of KWS in schools is mediated by staff experiences and perceptions of KWS. The current study is one of the first to explore KWS use in mainstream schools. Aims: To…

Currently, a small number of studies discuss augmentative and alternative (AAC) interventions in low- and middle-income countries (LMICs). The primary purpose of this scoping review was to summarize the current evidence base on communication-based interventions and partner training in LMICs, to explore and identify gaps in the AAC evidence base…

This study used the standard setting to establish cutscores for the fidelity of implementation of an evidence-based intervention, the Self-Determined Learning Model of Instruction (SDLMI) designed to enhance goal-directed actions in secondary students with and without disabilities. Cutscores were then applied to fidelity data from a large,…

School-wide positive behavior interventions and supports (SWPBIS) is a tiered framework that supports the academic, social, and behavioral needs of students. In this study, we conducted a conceptual replication of Grasley-Boy et al. (2022a) and used a series of two-level linear multilevel analyses to examine the impact of SWPBIS fidelity on 10…

Autistic youth frequently experience interfering anxiety, and schools may be an ideal setting to deliver mental health care. A type 1 hybrid-effectiveness, cluster randomized trial was used to examine the effectiveness of school-based Facing Your Fears compared to usual care. Change in provider cognitive behavior therapy knowledge and treatment…

The purpose of this study was to examine the efficacy of a teacher-implemented professional development program to increase the fidelity with which paraeducators use evidence-based practices (EBPs) in instruction for children with autism. Employing a modified multiple-probe design, investigators implemented the Autism Focused Intervention…

To support all students, including students with disabilities, many schools have adopted a positive behavioral interventions and supports (PBIS) framework. Although rigorous research documents the beneficial effects of Tier 1 PBIS for all students and emerging research extends these findings to students with disabilities, there has not been a…

Teachers working in a special education self-contained classroom were required to implement evidence-based practices and interventions, rarely researched in a school setting, with fidelity to meet the needs of students with intellectual disabilities. Evidence-based practices and interventions for students with intellectual disabilities were…
