We chose the DAWBA because: (a) it can be completed by parents online or by interview (telephone or face‐to‐face) (b) interviewers need little training, which can be done by reviewing online materials (Youth inmind, 2012) (c) it is quick to administer, the ASD module taking 20 min to complete (d) diagnosis is aided by computerised algorithm that generates a probability of disorder according to DSM‐IV and ICD‐10 criteria (e) a summary is automatically generated for each case (including probability of disorder, DSM/ICD criteria endorsed and verbatim responses to open‐ended questions) for review by clinicians. It is an online package of questionnaires designed to collect information sufficient to make a range of psychiatric diagnoses according to DSM‐IV and ICD‐10 criteria, with the ASD module gathering information required to diagnose ASD. The Development and Well‐Being Assessment (DAWBA Goodman, Ford, Richards, Gatward, & Meltzer, 2000) is a promising diagnostic tool for community settings. There is a need for simpler, cost‐effective and reliable tools to aid diagnosis in community settings. ![]() Many community services have struggled to adopt these instruments because of the level and cost of training and the time‐ and labour‐intensive nature of the interviews. The ADI‐R and DISCO are semistructured interviews carried out by highly trained clinical interviewers and take 2–3 hr to complete, whereas the 3di is a computer‐based interview that takes trained interviewers 90 min to complete. 1203).Ĭurrently, the best‐established diagnostic tools for collecting an autism‐specific history are the Autism Diagnostic Interview–Revised (ADI‐R Lord, Rutter, & Le Couteur, 1994), the Diagnostic Interview for Social Communication Disorders (DISCO Wing, Leekham, Libby, Gould, & Larcombe, 2002), and the Developmental, Dimensional and Diagnostic Interview (3di Skuse et al., 2004). Similarly, the American Academy of Pediatrics emphasised the importance of determining ‘the presence of a categorical DSM‐IV‐TR diagnosis, preferably with standardized tools that operationalize the DSM criteria’ (Johnson & Myers, 2007, p. Recognising the increased demand for diagnostic services, National Institute for Health and Clinical Excellence guidance (NICE, 2011) recommends that every autism diagnostic assessment includes ‘a developmental history, focusing on developmental and behavioural features consistent with ICD‐10 or DSM‐IV criteria’ preferably using an ‘autism‐specific tool’ (p21). © 2017 International Society for Autism Research, Wiley Periodicals, Inc.Since 1990 there has been a dramatic increase in the number of children presenting for assessment for autism spectrum disorder (ASD) in the United Kingdom (Taylor, Jick, & Maclaughlin, 2013) and United States (Autism and Developmental Disabilities Monitoring Network Principal Investigators, Centers for Disease Control and Prevention, 2014). The data show that the CAST can be a valid and reliable questionnaire for ASD screening in Spanish clinical and community populations. Like previous adaptation studies, a two‐factor structure was found. Correlations were high between the Spanish full and reduced versions of the CAST, and ADI‐R (Autism Diagnostic Interview Revised) and ADOS‐2 (Autism Diagnostic Observation Schedule, Second Edition). Some items showed low discriminating power and these results led us to propose a reduced version with 28 items and a cut‐off score of 13, which presented a high sensitivity (85.7%) and specificity (91.16%), a PPV of. The full Spanish version with a cut‐off score of 15 presented a high sensitivity (83.9%) and specificity (92.5%), a positive predictive value (PPV) of. Factorial and convergent validity is also assessed. This study provides evidence on its psychometric properties, describe its validity for screening and provides data on its discriminative capabilities in a Spanish sample of 4-12 year‐old children from community and clinical settings (N = 1460 and 36, respectively). The Childhood Autism Spectrum Test (CAST Scott, Baron‐Cohen, Bolton & Brayne, 2002) has proved to be a good test for screening autism spectrum disorders (ASD) and social communication problems. ![]() ![]() This study provides evidence on its psychometric properties, describe its validity for screening a.
