This systematic review aimed to identify factors significantly associated with the occurrence of epilepsy in autistic individuals and to consider the impact of study quality on findings. Electronic databases were systematically searched on October 2nd, 2020 and records retrieved were limited to those published from 2000 onwards. Study quality was…

Background: Although competitive integrated employment (CIE) has been established as a goal of employment research, policy, and practice for individuals with intellectual and developmental disabilities, the secondary benefits of CIE are rarely discussed. Aims: The purpose of this systematic review was to analyze and synthesise research related to…

Growing interest in the pathogenesis of autism spectrum disorders (ASDs) and other intellectual and developmental disabilities (IDD) has led to emerging evidence implicating a role for oxidative stress. However, understanding the strength of this association is made challenging by the use of a variety of purported biomarkers of oxidative stress,…

Background: There is a high prevalence of challenging behaviors (CB) in adults with intellectual disability (ID), which lead to negative personal outcomes and diminished quality of life. Emerging evidence suggest attachment theory could be useful to address CB in adults with ID and lower the negative impact on their social environment. Methods: A…

Background: Interventions for offenders with intellectual disabilities (ID) have used cognitive variables as measures of treatment outcome. However, the relevance of cognitive variables to offending in people with intellectual disabilities is unclear. This review aimed to evaluate the evidence for a relationship between cognitive variables and…

Background: There is strong evidence indicating that paid employment is generally good for the physical and mental health of the general population. This systematic review considers the association between employment and the health of people with intellectual disabilities. Methods: Studies published from 1990 to 2018 were identified via electronic…

Introduction: The aim of this systematic review was to synthesize the literature on the correlates and risk factors of anxiety among adults with ID. Methods: Following the PRISMA guidelines, a systematic search of peer-reviewed literature was conducted across six major electronic databases. From an initial screening of 844 records, 13 studies were…

The purpose of this scoping review was to examine the literature about the participation of students with intellectual disability in community-based work experiences (CBWEs). We analyzed 54 original research articles written in English, conducted in the United States, and published between 1975 and 2020 in peer-reviewed journals. We identified…

Background: People with intellectual disabilities are more likely to experience poor health than the general population and are frequently prescribed multiple medications. Therefore, it is important that people with intellectual disabilities understand their medication and potential adverse effects. Method: A scoping review explored people with…

Background: Epilepsy and challenging behaviour are both highly prevalent in the intellectual disability (ID) population and it is thus crucial to understand any possible associations between the two. Method: PsycINFO, MEDLINE, Embase, CINAHL and Web of Science were searched for quantitative data about epilepsy and any forms of challenging…

Children exposed to intimate partner violence (IPV) can experience negative social, emotional, behavioral, and academic outcomes. A growing body of research has examined the relationship between intellectual and developmental disabilities (IDD) and IPV exposure. We systematically reviewed the literature for research exploring this relationship and…

Background: Mortality studies can help reduce health inequalities by informing public policy through a better understanding of causes of death and comorbidities. Mortality studies often rely on Medical Certificates of Cause of Death (MCCD) for data. Method: A systematic review was undertaken to identify the extent and nature of issues in recording…

Intelligence tests and adaptive behavior scales measure vital aspects of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability. The present study investigated the population correlation between intelligence and adaptive behavior using psychometric meta-analysis. The main…

Rhyme awareness is a typical component of preschool curricula, yet research evidence does not support a direct link between rhyming ability in typically developing preschoolers and later literacy acquisition. Since the evidence base on literacy development among typically developing children is often used to guide intervention among children with…

Background: Constipation can lead to serious health issues and death. This systematic review summarizes international research pertaining to the management of constipation in people with intellectual disability. Method: Studies published from 1990 to 2017 were identified using Medline, Cinahl, PsycINFO, Web of Science, email requests and…
