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…

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…

Over 50 years of research suggests that toilet training based on behavioral principles is effective for most individuals with intellectual and developmental disabilities (IDD). However, many adults with IDD are never effectively toilet trained. Lack of independent toileting is associated with detrimental physical, mental, and social experiences.…

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…

Introduction: For in-person psychotherapy, psychotherapists make individual adaptions to meet clients' disability-related needs, for example, by providing plain or sign language. Such adaptations apply to different types of psychotherapy (e.g. psychodynamic, systemic, or cognitive-behavioral). Digital interventions, such as video psychotherapy or…

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…

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…

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…

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: The prevalence of obesity among individuals with intellectual and developmental disabilities (IDD) is equal to or greater than the general population. Methods: Overweight/obese adults (BMI =25 kg/m2) with mild-to-moderate intellectual and developmental disabilities were randomized to an enhanced stop light diet…

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…

Background: Although parental stress is higher for children with neurodevelopmental disorders (NDs), it is unclear how this stress compares to more common NDs. The current study compared stress in parents of children with Williams syndrome (WS), Down syndrome (DS) and autism spectrum disorders (ASD). The impact of individual and contextual factors…

Background: Participation in social and physical activities has a number of benefits for children with or without disabilities. However, individuals with disabilities are often excluded from taking part in social activities. Most of the research on activity participation has focused on adults or youth with milder disabilities. However, children…

States have increasingly transitioned Medicaid enrollees with disabilities from fee-for-service (FFS) to Medicaid Managed Care (MMC), intending to reduce state Medicaid spending and to provide better access to health services. Yet, previous studies on the impact of MMC are limited and findings are inconsistent. We analyzed the impact of MMC on…

Anxiety disorders affect ~ 15-20% of youths without neurodevelopmental disorders, with persons having autism spectrum disorder (ASD) and fragile X syndrome (FXS) at elevated risk for anxiety disorders. Few studies have compared rates and predictors of anxiety disorders in adolescents with FXS or ASD. This study directly compares rates, predictors,…
