Identifying children with developmental disabilities is critical in providing early intervention services. This study aimed to evaluate the concurrent validity information of the 24-, 30-, and 36-month Indonesian Ages and Stages Questionnaires third edition (ASQ-3) with Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) in…

Urine-detecting alarms are prevalent in toilet training intervention research and clinical practice for individuals with intellectual and developmental disabilities, but the effects of urine alarms remain unclear. Urine alarms may function as punishing or reinforcing contingencies, or may merely alert trainers to accidents and improve treatment…

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…

It has been proposed that an implicit learning deficit explains the difficulties with grammar commonly observed in children with Developmental Language Disorder (DLD). The present study further investigates this link in two ways. Firstly, we investigate whether kindergartners with DLD have more difficulties with preposition understanding and…

Background: Women with intellectual and developmental disabilities face poorer reproductive and pregnancy outcomes partially due to health care inequity. Our objective was to conduct a scoping review of reproductive and pregnancy related health care among women with intellectual and developmental disabilities. Methods: We systematically reviewed…

This study used an adapted alternating treatments design to compare the effectiveness of two different procedures for fading video prompts for teaching two individuals with developmental disabilities and moderate intellectual disability to independently perform two different daily living tasks. The tasks were systematically faded from video…

Behavior analysts typically teach conditional discriminations in a mixed-trial format but may switch to a blocked-trial format for learners displaying limited acquisition. No known research has shown that mixed-trial methods are more effective or efficient than blocked-trial methods for teaching discriminations, so it is not clear why this format…

Purpose: This study examines the effects of enhanced conversational recast for treating morphological errors in preschoolers with developmental language disorder. The study assesses the effectiveness of this treatment in an individual or group (n = 2) setting and the possible benefits of exposing a child to his or her partner's treatment target in…

This study explores the psychometric properties of "Self-Determination Inventory: Student Report" (SDI:SR) in students with intellectual and developmental disabilities (IDD) and without disabilities in China. The paper-and-pencil version of SDI:SR Chinese Translation (SDI:SR Chinese) was used to explore self-determination across students…

Noncompliance with adult instruction is a common problem exhibited by individuals diagnosed with intellectual and developmental disabilities. The high-probability (high-p) request sequence was designed to increase compliance with low-probability (low-p) instructions by rapidly presenting high-p instructions immediately prior to the targeted low-p…

Purpose: This study investigated the effects of signs on word learning by children with developmental language disorder (DLD), in comparison with typically developing (TD) children, and the relation between a possible sign effect and children's linguistic and cognitive abilities. Method: Nine- to 11-year-old children with DLD (n = 40) and TD…

Feeding problems are known to be an important clinical issue for children with autism spectrum disorder (ASD), but the majority of studies on this topic have been carried out on children preschool age and older. It is important to understand whether these difficulties begin prior to age 3 years, as well as what parameters are important to study…

Individuals with autism spectrum disorder (ASD) have higher rates of co-occurring diagnoses and use of psychotropic medication prescriptions than people with other developmental disabilities. Few studies have examined these trends in samples of people with intellectual and developmental disabilities (IDD) with and without ASD. Using a random…

Video-based instruction (VBI) has a substantial amount of research supporting its use with individuals with autism spectrum disorder and other developmental disabilities. However, it has typically been implemented as a treatment package containing multiple interventions. Additionally, there are procedural variations of VBI. Thus, it is difficult…

Purpose: This study examined whether college students with developmental language disorder (DLD) could use distributional information in an artificial language to learn about grammatical category membership in a way similar to their typically developing (TD) peers. Method: Seventeen college students with DLD and 17 TD college students participated…
