Abstract
The goal of this project has been the creation of a Composite-based short-form of the WPPSI-III (Primary) which is able to use any combination of subtests whilst also supplying the same range of comprehensive analytic methods that are available for the full-length version. Additionally, the current short-form application provides further quantitative methods that exceed those that are available for the full-length version. The psychometric methods employed are based on those developed by Crawford et al. (2010) for fixed subtest short-forms but are extended to allow users to select the subtests included in the short-form. Because the calculations are complex and time consuming (and need to be carried out in real time because of the large number of potential short-forms) the methods are implemented in a computer program for end users. The use of the short-form (and of the accompanying program) is illustrated with examples. The short-form produces confidence intervals on scores, and allows analysis of the reliability and abnormality of differences in a child’s profile of scores. The short-form and its associated methods should prove to be a useful tool in both clinical practice and research validity.
