Background: Many children experience delayed or missed identification of an intellectual disability diagnosis, meaning that key opportunities for early educational intervention may be lost. Methods: Semi-structured interviews were used to explore the views of teachers, parents, and clinicians (n = 22), about the use of the Child and Adolescent…

Background: We explored the accuracy of using the learning disability screening questionnaire (LDSQ) in services for people experiencing homelessness in the United Kingdom. Method: We examined the concordance between the LDSQ outcomes and assessments of intellectual disability. Seventy adults experiencing homelessness completed the LDSQ. Staff…

Background: One contributor to the health inequalities that people with an intellectual disability face is failure to identify their intellectual disability. The Learning Disability Screening Questionnaire (LDSQ) can identify adults who are likely to have an intellectual disability, but little is known about its impact. Methods: A modified Delphi…

There is an increasing emphasis on the importance of research having an impact on policy and practice. This can be more difficult to evidence in intellectual disability services because of the wide range of stakeholders involved. We evaluated whether an impact questionnaire covering: knowledge production, capacity building, informing policy and…

Background: People with learning disabilities are at increased risk of physical health conditions and mortality compared to the general population. Initiatives to address these health inequalities include the introduction of learning disability registers, through which people with learning disabilities can be identified and offered annual health…

Background: The increasing number of individuals with an intellectual disability who are at risk of developing dementia highlights the need to use measures with strong psychometric properties as part of the screening, assessment and diagnostic process. Method: Searches were made of clinical and good practice guidelines and English language journal…

Background: There has been only limited research into the psychometric properties of short-form intellectual assessments when used with children who may have an intellectual disability (ID). The aim of this study was to evaluate an 8-subtest short form of the Wechsler Intelligence Scale for Children -- Fourth Edition (WISC-IV) in children assessed…

The Learning Disability Screening Questionnaire (LDSQ), a brief screening tool for intellectual disability, was originally validated against the Weschler Adult Intelligence Scale, Third Edition (WAIS-III), which was superseded by the Weschler Adult Intelligence Scale, Fourth Edition (WAIS-IV) in the United Kingdom in 2010. This study examines the…

Background: It is important that screening tools for intellectual disability are validated against the diagnostic criteria relating to intellectual and adaptive functioning, as well as childhood onset, but researchers often focus only on intellectual functioning. This brief report aimed to explore the convergent validity of the Child and…

Background: Outcomes for people with an intellectual disability (ID) may differ depending on the severity of the condition. This study evaluated whether a tool used to screen for the presence of ID could also give an early indication of severity, in order to help inform future support needs. Methods: Multicategory receiver operating characteristic…

There is a need for brief screening instruments for autistic spectrum disorders (ASD) that can be used by frontline healthcare professionals to aid in the decision as to whether an individual should be referred for a full diagnostic assessment. In this study we evaluated the ability of a short form of the autism spectrum quotient (AQ)…

The study assessed the validity of an intellectual disability screening tool, the Learning Disability Screening Questionnaire (LDSQ), in three forensic settings: a community intellectual disability forensic service; a forensic in-patient secure unit and a prison, using data for 94 individuals. A significant positive relationship was found between…

Background: Early identification of possible intellectual disability can help children and families access appropriate services and support more quickly. There has been an increasing interest in the use of screening tools for this purpose. This study reviews the literature in relation to such tools. Methods: A literature search was carried out for…

The study outlines the evaluation of an intellectual disability screening tool, the "Child and Adolescent Intellectual Disability Screening Questionnaire" ("CAIDS-Q"), with two age groups. A number of aspects of the reliability and validity of the "CAIDS-Q" were assessed for these two groups, including inter-rater reliability, convergent and…
