The objective was to investigate the transcultural diagnostic validity of the Social Communication Questionnaire (SCQ) in a clinical sample of 451 adults with Intellectual Developmental Disorder (IDD) with and without ASD in Germany, the U.S.A. and Great Britain. Variables associated with higher SCQ sum-scores were higher levels of IDD, male gender, a diagnosis of ASD and the study site (Germany > U.S.A > G.B.). An ROC analysis revealed a cut-score of 13, which resulted in a sensitivity of 0.87 and a specificity of 0.58. It is recommended to adjust the cut-score according to level of IDD and gender. Further research is needed to align diagnostic assignment of ASD across different sites and countries.

The Social Communication Questionnaire for adults with intellectual disability: SCQ-AID / Olivia DERKS in Autism Research, 10-9 (September 2017)  

Public ISBD [article]  inAutism Research > 10-9 (September 2017) . - p.1481-1490 Titre : The Social Communication Questionnaire for adults with intellectual disability: SCQ-AID Type de document : texte imprimé Auteurs : Olivia DERKS, Auteur ; Manuel HEINRICH, Auteur ; Whitney BROOKS, Auteur ; Paula STERKENBURG, Auteur ; Jane MCCARTHY, Auteur ; Lisa UNDERWOOD, Auteur ; Tanja SAPPOK, Auteur Article en page(s) : p.1481-1490 Langues : Anglais (eng) Mots-clés : autism spectrum disorder (ASD)  intellectual disability (ID)  social communication questionnaire (SCQ)  assessment  validity Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) frequently co-occurs with intellectual disability (ID) and often remains undiagnosed until adulthood. The Social Communication Questionnaire (SCQ) is a widely used measure to screen for ASD. To improve the utility of the SCQ for adults with ID, the aim of this study was to develop an ID-specific and adult appropriate algorithm for the SCQ using a core set of valid items. These items were identified in one sample (N = 226) and further cross-validated in a second, independent sample (N = 225) from Germany, England and the U.S. The newly developed algorithm has 24 items compared with the 40 items in the original instrument. The reduced item core set yielded similar diagnostic validity as the original algorithm with good sensitivity values (0.81–0.89) and low specificity values (0.62–0.72). Overall, these results suggest that the removed items may not carry diagnostically relevant information in adults with ID; thus, excluding these items may result in a more efficient and age-appropriate screening measure for this population. However, due to the low specificity values, a comprehensive assessment is essential for a final diagnostic assignment.

The validity of the social communication questionnaire in adults with intellectual disability / Whitney BROOKS in Research in Autism Spectrum Disorders, 7-2 (February 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-2 (February 2013) . - p.247-255 Titre : The validity of the social communication questionnaire in adults with intellectual disability Type de document : texte imprimé Auteurs : Whitney BROOKS, Auteur ; Betsey A. BENSON, Auteur Année de publication : 2013 Article en page(s) : p.247-255 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorders (ASD)  Intellectual disability (ID)  Adults  Social Communication Questionnaire (SCQ)  Screening measures  Validity Index. décimale : PER Périodiques Résumé : This study assessed the validity of the Social Communication Questionnaire (SCQ) in a sample of 69 adults, aged 18'40 years old. Participants included 21 adults diagnosed with an autism spectrum disorder (ASD) and intellectual disability (ID), and 48 individuals diagnosed with ID and no diagnosis of an ASD. The SCQ yielded a sensitivity of .71 and a specificity of .77 at the authors' recommended cutoff score of 15 (Berument et al., 1999). However, when sensitivity was prioritized over specificity, the optimal cutoff score was 12, which yielded a sensitivity of .86 and a specificity of .60. The internal consistencies of the total scale (' = .87), the social interaction subscale (' = .83), and the restricted repetitive behavior subscale (' = .81) were good, but the communication subscale performed poorly (' = .48). The SCQ shows promise as a screening measure for adults with ID whose early developmental history may be unavailable. A lower cutoff score than the authors originally proposed is recommended in adults.
