Functional communication training (FCT) is an evidence-based practice used to mitigate challenging behavior by increasing functional communication skills. To increase the practicality and feasibility of FCT in natural settings, thinning schedules of reinforcement are typically programmed following FCT. In this review, we meta-analyzed 28 studies…

Paraeducators are ideal candidates for delivering communication interventions to children with developmental disabilities and delays (DD) because they spend a significant amount of time with these children. However, professional development is often inadequate and limited research supports best practices. Additionally, paraeducators work with…

This study evaluated the effects of a pyramidal training approach that used an expert trainer who taught teachers how to train their paraeducators. Three special education teachers were taught to train four paraeducators to provide students with intellectual and developmental disabilities opportunities to initiate (OTI). A multiple baseline design…

Two non-U.S. quasi-experimental studies reported Active Support training was associated with increased engagement in individuals with IDD, but no randomized controlled trials (RCTs) exist. We evaluated effects of Active Support training on staff assistance, and social and nonsocial engagement in 75 individuals with intellectual and developmental…

Purpose: The aim of this study was to determine whether parents of children with developmental language disorder (DLD) were aware of their children's language difficulties and whether a brief, classroom-based language screen can reliably identify children at risk for DLD, including those with both good and poor word reading skills. Method: First-…

Students with intellectual and developmental disabilities (IDD) require intensive supports to make progress on literacy goals. These supports must often include methods to decrease challenging behaviors and increase engagement during instruction. In this study, I investigated whether computer-assisted instruction (CAI) may be one effective method…

This paper provides an overview of five review studies that analyzed 92 single subject studies on the effectiveness of major augmentative and alternative communication (AAC) systems for individuals with developmental disabilities including autism. This paper offers recommendations useful for AAC decision-making points. Research on the…

Purpose: Although the 5 studies presented within this clinical forum include children who differ widely in locality, language learning profile, and age, all were motivated by a desire to improve the accuracy at which developmental language disorder is identified within linguistically diverse schools. The purpose of this prologue is to introduce…

Purpose: Modeling of grammatical forms has been used in conjunction with conversational recast treatment in various forms. This study tests the relative effect of providing bombardment prior to or after recast treatment. Method: Twenty-eight children with developmental language disorder participated in daily conversational recast treatment for…

Purpose: The purpose of this tutorial is to discuss the language basis of dyslexia in the context of developmental language disorders (DLDs). Whereas most studies have focused on the phonological skills of children with dyslexia, we bring attention to broader language skills. Method: We conducted a focused literature review on the language basis…

Families of children with autism spectrum disorder (ASD) play a central role in selecting interventions for their children. Despite the importance of understanding the factors that motivate early decisions about treatment, the literature has concentrated little attention on how and why parents of young children with ASD make decisions about…

Using the family resilience model, we examined the association between empowerment, family member age, length of institutionalization, and resilience among family members of relatives with intellectual and developmental disabilities (IDD) following deinstitutionalization. Participants included 56 family members whose relatives with IDD recently…

In an era of globalization, receiving postsecondary education (PSE) becomes necessary for young adults to gain meaningful employment and earn a decent income that supports his or her independent living. The same is true for individuals with intellectual and developmental disabilities who desire for inclusive employment and community living.…

Purpose: Estimates of the expected co-occurrence rates of idiopathic language disorder and attention-deficit/hyperactivity disorder (ADHD) provide a confusing and inconsistent picture. Potential sources for discrepancies considered so far include measurement and ascertainment biases (Redmond, 2016a, 2016b). In this research symposium forum…

Background: It has been established that people with autism spectrum disorder (ASD) often have difficulties understanding spoken language. Understanding reflexive and clitic pronouns is vital to establishing reference-based inference, but it is as yet unclear whether such constructions pose specific difficulties for those with ASD. Pronoun…
