Co-occurring intellectual/developmental disability (IDD) and overweight/obesity (OW/OB) is an important consideration of IDD psychiatric care. The relationship between OW/OB and comorbid diagnoses of Autism Spectrum Disorder (ASD) and/or IDD remains inadequately described in existing literature. The purpose of this study is to explore these…

Objective: This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods: A retrospective chart review studied characteristics of severe…

Background: There is a clear predominance of programmes aimed at improving aspects related to language production in pupils with developmental language disorder (DLD). However, programmes aimed at improving their receptive skills are limited. Aims: The main aim was to assess the effectiveness of an intervention programme for oral language…

Background: Although burnout has been recognised as an important stress-related problem among staff working with people with intellectual and developmental disabilities (IDD), literature on the subject is limited yet emerging. The aim of this study is twofold: (1) to evaluate the level of burnout within different professions working with IDD; (2)…

Findings from a research synthesis of the relationships between family needs and parent, family, and child functioning are reported. The synthesis included 31 studies conducted in 12 different countries. The studies were conducted between 1987 and 2021 and included 4,543 participants. Eight different family needs scales or adaptations of the…

The DSM-5 features level of support ratings for social communication (SC) and restrictive and repetitive behaviors (RRB) for individuals with autism spectrum disorder (ASD). We contrasted cognitive, adaptive, and autism severity scores across SC and RRB groups for 158 individuals with ASD diagnosed in a developmental disabilities clinic. Roughly…

Background: Associations between childhood adversity and negative health outcomes are well documented within the general population; however, this relationship has yet to be confirmed in adults with intellectual and developmental disabilities (I/DD). Bridging the gap between public health and I/DD research is critical in order to better understand…

People with learning disabilities are sometimes prescribed psychotropic medication to help manage their challenging behaviour. This case study describes how a multicomponent behavioural intervention in conjunction with the systematic withdrawal of sodium valproate was strongly correlated with reduced aggression. No symptoms of bipolar disorder or…

Problem Statement: Because communication skills, particularly pragmatic skills, are fundamental for living an independent life in society, these skills are vital to the quality of life of individuals with developmental disabilities (DD) and their families. Studies of the pragmatic skills of individuals with DD can provide important insights into…

The behaviors frequently displayed by students with autism can place them at risk for overly reactive behavior interventions with unwanted side effects. The current study examined the level of intrusiveness of behavioral treatments developed for 198 students with disabilities from 13 different states. Results demonstrated that students diagnosed…

Children with 22q11.2 deletion syndrome exhibit high rates of social-behavioral problems, particularly in the internalizing domain, indicating an area in need of intervention. The current investigation was designed to obtain information regarding parent and teacher ratings of the social-emotional behavior of children with 22q11DS. Using the Child…

The purpose of this article is to describe communicative-participation outcomes measured by the Focus on the Outcomes of Communication Under Six (FOCUS©; Thomas-Stonell et al., 2013) for interventions provided by speech-language pathologists (SLPs) in different community settings for preschoolers with speech-language impairments (Sp/LI) with and…

Aim: To examine the internal consistency, test-retest reliability, and responsiveness of the Movement Assessment Battery for Children--Second Edition (MABC-2) Test for children with developmental coordination disorder (DCD). Method: One hundred and forty-four Taiwanese children with DCD aged 6 to 12 years (87 males, 57 females) were tested on…

Children with intellectual and developmental disabilities are at heightened risk for mental disorders. Using current diagnostic criteria, disruptive behavior disorders, specifically Attention-Deficit/Hyperactivity Disorder (ADHD), appear to be the most prevalent co-occurring disorders. However, the validity of ADHD as a diagnosis for children and…

This paper includes a nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies. Different hypothetical studies are used to illustrate how null hypothesis significance testing (NHST) and effect size findings can result in quite different outcomes and therefore conflicting results. Whereas…
