The publication of John Hattie's "Visible Learning: A synthesis of over 800 meta-analyses relating to achievement" in 2009 has led to the widespread adoption of the Visible Learning program around the world. Critique of this program has been less widespread, especially in English, and has tended to centre on the mechanisms of…

Investigated internal consistency reliability and criterion validity of the Asperger Syndrome Diagnostic Scale (ASDS) in a well-characterized sample of 120 children ([X-bar][subscript age] = 9.91; autism [AUT] n = 54; non-autism [NOT] n = 66) who completed comprehensive outpatient evaluations with a gold-standard measure, the Autism Diagnostic…

Background: Phelan-McDermid Syndrome (PHMDS)/22q13.3 deletion syndrome is a rare genetic disorder linked to Autism Spectrum Disorder (ASD) and Intellectual Disability (ID). There are reports of PHMDS co-occurring with psychiatric disorders, but little is known about the assessment of such disorders in PHMDS. Method: A case study focusing on a…

A long history of racism and ableism exists within the U.S. and shapes policies, practices, and assumptions within the public education system. Racism and ableism are built into educator and principal practices, which contribute to the reproduction of inequitable systems and outcomes. Yet, principals are in a key position to challenge dominant…

Background: People with learning disabilities have an increased risk of diabetes, cardiovascular disease and hearing loss. This study explored service users' and health professionals' perspectives and experiences of adopting minimally invasive diagnostic and screening devices, known as point-of-care testing (POCT) as a means of improving access…

It is well-recognized that measurement options for diagnosing and monitoring children with neurogenetic syndromes (NGS) associated with moderate to severe intellectual impairment are limited (Berry-Kravis, Dev Med Child Neurol 10.1111/dmcn.13018, 2016), and caregivers experience significant concerns regarding the assessment process. However to…

In this research, leisure activity engagement of students with intellectual disabilities was examined. This study aims to compare the engagement of students with intellectual disability in leisure time activities that they chose with the ones that were selected by their teachers. Four students diagnosed with intellectual disability at the age of…

Background: The cardiovascular disease (CVD) risk is high in adults with intellectual disabilities. This CVD risk can potentially be decreased with a resistance training (RT) programme at vigorous intensity, following previous research on successful High-Intensity Training programmes. Our aim was to explore the feasibility of a vigorous…

Background: Organizational culture in group homes for people with intellectual disabilities has been identified as influencing staff behaviour and residents' quality of life (QOL). Despite this influence, culture has been under-researched, with no published and validated instrument to measure its dimensions in group homes. The aim was to develop…

Background: Children with dyslexia and/or developmental language disorder (hereafter children with DDLD) have been reported to retrieve fewer words than their typically developing (TD) peers in semantic fluency tasks. It is not known whether this retrieval difficulty can be attributed to the semantic structure of their lexicon being poor or,…

The social and motor context in which restricted and repetitive behaviors (RRBs) occur in autism and their relationship to social traits are not well-understood. Participants with and without autism completed tasks that varied in social and motor engagement and RRB frequency was measured. Motor and verbal RRBs were most common, RRBs varied based…

Although informed consent is critical for all research, there is increased ethical responsibility as individuals with intellectual or developmental disabilities (IDD) become the focus of more clinical trials. This study examined decisional capacity for informed consent to clinical trials in individuals with fragile X syndrome (FXS). Participants…

Research suggests that autistic children can provide accurate and forensically useful eyewitness evidence. However, members of a jury also rely on non-verbal behaviours when judging the credibility of a witness, and this could determine the verdict of a case. We presented mock jurors with videos (from an experimental study) of one of two child…

Background: Older people with intellectual disability (ID) are at high risk of incidents leading to hospital visits. Method: Through national registers, 7936 people with ID, aged 55+ years in 2012, and a same-aged referent cohort from the general population were identified. Information on diagnoses made in inpatient and outpatient specialist…

Easy-to-read (ETR) German is the subject of public debate. Even though it is heavily promoted by officials, its status is controversial. Moreover, the comprehensibility of ETR German texts awaits systematic testing. The aim of the present study was to test a controversial rule concerning word segmentation. Hypotheses derived from psycholinguistic…
