MURRAY, Auteur Article en page(s) : 102076 Langues : Anglais (eng) Mots-clés : Intellectual disability  Autism spectrum disorder  Screening  Child and adolescent intellectual disability screening questionnaire Index. décimale : PER Périodiques Résumé : Background There is high co-occurrence between intellectual disability and Autism Spectrum Disorder (ASD). It is important to identify people who have both conditions for clinical and research reasons. This study explored if the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q) and Learning Disability Screening Questionnaire (LDSQ) could accurately identify intellectual disability in autistic children and adults respectively. Method Pre-existing CAIDS-Q data for 40 autistic children and LDSQ data for 27 autistic adults were used. The participants were classified as likely to have an intellectual disability or not based on the age-appropriate cut-off score on the relevant screening tools. This was compared with their clinical diagnosis of intellectual disability. Results The sensitivity, specificity, and positive and negative predictive values, for the CAIDS-Q were 93.1 %, 88.5 %, 90 % and 92 % respectively. The corresponding figures for the LDSQ were 75 %, 95.6 %, 75 %, and 95.6 %. Conclusions The values for the CAIDS-Q were broadly consistent with figures found in previous research. The sensitivity and PPV figures for the LDSQ, were somewhat lower. The specificity and sensitivity values for both measures were above the threshold for levels that are generally considered to be acceptable for a developmental screening tool. The results suggest that the CAIDS-Q and LDSQ may be appropriate measures to screen for intellectual disability in autistic people.

Screening tools for autism spectrum disorder, used with people with an intellectual disability: A systematic review / Dale METCALFE in Research in Autism Spectrum Disorders, 74 (June 2020)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 74 (June 2020) . - p.101549 Titre : Screening tools for autism spectrum disorder, used with people with an intellectual disability: A systematic review Type de document : Texte imprimé et/ou numérique Auteurs : Dale METCALFE, Auteur ; Karen MCKENZIE, Auteur ; Kristofor MCCARTY, Auteur ; George MURRAY, Auteur Article en page(s) : p.101549 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Intellectual disability  Screening  Diagnosis Index. décimale : PER Périodiques Résumé : Background A diagnosis of autism spectrum disorder (ASD) can be beneficial in ensuring the person receives appropriate support. People with intellectual disability often have undiagnosed co-occurring ASD, due to the specific diagnostic challenges that having intellectual disability can present. Screening tools can be useful to indicate those who are likely to require full diagnostic assessment of ASD. Method We conducted a systematic review of the literature. The databases ProQuest, PsycArticles, PubMed, and Web of Science were searched for articles published before July 2019. When duplicates were removed 3068 articles were retained. Articles were removed in stages and were retained if there was a possibility that the content was relevant. In total, 14 articles were reviewed fully. Results The articles covered eight ASD screening instruments and were reviewed in respect of the quality of the available reliability and validity data when used with people with intellectual disability. Conclusion A few tools have psychometric properties that indicate they have potential to screen for ASD in people with intellectual disability, but overall research with this group is limited, particularly in terms of reliability. The implications for screening and diagnosis of ASD in people with intellectual disability are discussed.
