Introduction: Sedentary behaviour among individuals with intellectual disabilities, driven by barriers such as limited access to adapted programs and low self-efficacy, contributes to chronic health conditions. This study evaluates the effectiveness of the Valemee Visual System (VVS), a novel tool offering visual support and structured exercise…

Background: The aim was to pilot an adapted manualised weight management programme for persons with mild-moderate intellectual disabilities affected by overweight or obesity ("Shape Up-LD"). Method: Adults with intellectual disabilities were enrolled in a 6-month trial (3-month active intervention and 3-month follow-up) and were…

Prior research suggests that the use of multimedia instruction along with video modeling increases the ability of individuals with intellectual disability (ID) to independently complete tasks. However, the previous research has not always included instruction of the underlying vocabulary, nor has it always resulted in skill maintenance. The…

This study examines the effects of a working memory (WM) sensitive math intervention in students with learning disabilities (LD). The intervention aims to improve early mathematical competencies while accounting for weak cognitive resources through a reduced instructional design. These principles are considered to be effective for learning. Ten…

Background: Knowledge about ageing from the perspective of people with intellectual disability is extremely scarce, which means a lack of evidence-based interventions for healthy ageing adjusted to their needs. Aim: To investigate how people with intellectual disability experience ageing, prior to an educational intervention. Methods: Twenty-six…

Background: Post-traumatic stress disorder (PTSD) is common in adults with intellectual disabilities. Often there are additional disorders such as substance use, mood and anxiety disorders. The current study focuses on the feasibility and initial efficacy of prolonged exposure (PE) for PTSD in adults with mild intellectual disabilities. The…

Appropriate physical education program for students with an intellectual disability can increase their engagement in inclusive physical activity; however, fewer than a quarter of students with an intellectual disability meet the current physical activity guidelines. In this study, we used a single-case multiple probe across participants design to…

Background: Challenging behaviour is a common problem among people with ID and in services for people with ID. This paper aims to provide an overview of the views and preferences of people with ID on challenging behaviour. Method: Semi-structured interviews were conducted with thirteen adults with mild to moderate ID and seven proxies (family or…

This chapter reviews the intervention research literature -- particularly interventions deemed evidence-based -- for students with intellectual disability across academic and life-skills instruction. Although the focus of this chapter is the spectrum of students covered under the term "intellectual disability," the majority of research…

Background: People with intellectual disability may be at elevated risk of adverse consequences of substance use. This study outlines the prevalence of, and factors associated with, substance use in young people with and without intellectual disability. Method: Secondary analysis was undertaken of the Next Steps annual panel study, which follows a…

This study provides the results of a meta-analysis of 31 single-case design studies on safety skills interventions for individuals with intellectual disabilities (ID). Results indicate that individuals who have mild to moderate ID, in particular school-age children, have benefited most from the safety skills interventions. In addition, the…

The purpose of the study was to evaluate whether students with intellectual disabilities (ID) can improve their arithmetic skills by participating in an arithmetic intervention programme, theoretically founded on explicit instruction (EI) and administered via an application developed for tablet computers. The intervention study used a randomised…

Background: Adolescents with mild-to-borderline intellectual disability face peer resistance challenges, risking harmful or dangerous situations. Method: We designed a peer resistance group intervention at school for adolescents with mild-to-borderline intellectual disability, tested its feasibility (N = 4, M[subscript age] = 14.1, M[subscript IQ]…

The aim of this study is to examine the effects of rhythm and dance on the aggression levels of students with mild mental disabilities. The sample group of the study consists of 40 students with mild mental disability, 20 of whom are in the experimental group and 20 in the control group, who continue their education in schools affiliated with the…

Assistive technology (AT) has been shown to be a promising method for supporting individuals with intellectual disability (ID) attain a higher degree of independence both at home and in the work place. The purpose of this alternating-treatment single-case research design study was to compare the effectiveness of three methods (i.e., Notes App,…
