| Abstract: | Little research has been conducted into the accuracy of abbreviated assessments in identifying children and young people with an intellectual disability (ID). The present study compared two such methods in a clinical population of individuals with (n = 106) and without (n = 170) ID: a 7-subtest short form of the Wechsler Adult Intelligence Scales for Children—fourth edition (WISC-IV) proposed by Crawford and colleagues and the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q). Both the CAIDS-Q and the WISC-IV short form had high and comparable levels of predicting group classification (88% and 91% correct classification, respectively). Both methods would appear to offer clinicians and researchers an efficient and accurate means of identifying those who are likely to have ID. The WISC-IV short form was slightly more accurate, but the CAIDS-Q may offer the advantages of being shorter to administer and having no requirement for the user to have a particular qualification or training. |
