Purpose: The purpose of this study was to examine English reading comprehension skills in Spanish-English bilingual children with and without developmental language disorder (DLD). In particular, we examined the contribution of Spanish and English oral language skills and of the language of instruction (i.e., English only or dual language) to…

Purpose: This study aims to investigate the learning potential of French-speaking children, either with typical development (TD) or with developmental language disorder (DLD), when learning an invented inflectional morphological rule. We tested the children's performance in learning pseudomorphemes of gender and number with dynamic assessment…

In this review, we summarized and meta-analyzed 35 single-case intervention studies that involved the use of multiple schedules of reinforcement with 78 individuals with intellectual and developmental disabilities. Based on Tau-U calculations, multiple schedules of reinforcement produced an overall large effect for appropriate communicative…

Aims: This study compared two dose frequency conditions of an explicit intervention with 50 trials per session designed to improve past tense marking in early school-aged children with developmental language disorder (DLD). The influence of allomorphs on intervention effects was also examined. Methods: Data from previously conducted intervention…

Purpose: This research note addresses whether task administration variations can improve Dimensional Change Card Sort (DCCS) performance in preschoolers with developmental language disorder (DLD). Method: Participants included preschoolers with DLD who failed the standard DCCS, which is characterized by inability to switch from one card sorting…

Background: This study examines recent trends in the age-at-death disparity between adults with and without intellectual and/or developmental disabilities in the United States. Method: Data were from the 2005-2017 U.S. death certificates. Average age at death was compared between adults whose death certificate did or did not report an intellectual…

Background: Individuals with intellectual/developmental disabilities are vulnerable to potentially traumatic events and trauma sequelae. Despite ongoing advances surrounding trauma and intellectual/developmental disabilities, trauma-specific treatments are needed for people with intellectual/developmental disabilities. This study explores the…

Performance for three independent living tasks were examined via task analyses. Given the relatively small sample size (n = 56) of individuals with intellectual and developmental disabilities, we simulated 1000 replications based upon observed results using Monte Carlo techniques. The results of the current study suggest that: (1) adaptive…

Students with intellectual and other developmental disabilities often require substantial support to acquire the skills needed to secure work experience and paid employment. Prior findings suggest that video prompting is likely to be an effective and feasible strategy for establishing such skills. To evaluate this possibility in a special…

The current study examined how employment conditions (competitive employment, work center employment, unemployment) are associated with the quality of life (QoL) for individuals with intellectual or developmental disabilities. Using the Comprehensive Quality of Life Scale -- Intellectual/Cognitive Disability (5th Edition; ComQoL-I5; Cummins,…

As a treatment for escape-maintained problem behavior, differential reinforcement of alternative behavior (DRA) is typically initiated by reinforcing compliance on a dense reinforcement schedule. This work schedule is then progressively thinned such that the individual is required to complete more work, up to some socially acceptable terminal…

Parents are the primary source of support for their children and can become principal interventionists for preventing and treating their child's challenging behavior. Yet, providing adequate and adapted training for culturally diverse families can be difficult due to the increase of international migration and the diversity of languages spoken…

Special education advocacy programs support families to secure services for their children with intellectual and developmental disabilities. Although research demonstrates the efficacy of one such program (the Volunteer Advocacy Project), its effectiveness when replicated by others is unknown. Replication research is critical to ensure that…

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…

"Promoting choice" is a defining value guiding Positive Behavior Support (PBS) models for serving individuals with intellectual and/or developmental disabilities (IDD). The ability to make independent choices is of paramount importance to self-advocacy and self-determination. Promoting choice is also an essential commitment of…
