Lucid Adult Dyslexia Screening (LADS)
Swift, objective and accurate identification of dyslexia for adults ages 16 and over
LADS provides quick and effective screening for dyslexia in a wide variety of adult settings. The tests will provide a swift but effective screening for dyslexic individuals in a wide variety of settings, including those in further and higher education. The Reasoning test has been included in order to calibrate the word recognition and word construction tests to increase the accuracy of detection of dyslexia in bright, well-compensated adults. The accuracy of LADS has been proven in extensive scientific trials, with fewer than 4% false positive ('false alarms') and 5% false negative ('misses') misclassifications.
The LADS tests are adaptive (i.e. the difficulty of the items varies in response to the ability level and performance of the person taking the test) so screening is swift and less stressful. On average, there is an overall screening time of about 20 minutes per person and the test can be self-administered, thus requiring minimal supervision.
The computer automatically generates a simple graphical report for each person assessed. Individual module scores are compared to normative data. Indications are given of whether or not the scores fall into the dyslexic 'risk' category. There is ample room on the report for administrators to add their own comments before the report is printed. The LADS reasoning module also provides an estimate of the person's general intellectual ability, which can be important when giving advice about further action after screening. The test is accompanied by a comprehensive Administrator’s Manual, which explains how to use the program and how to interpret results. The final section of the Manual (which has been written by E.A. Draffan of Sussex University’s Assistive Technology Unit) covers a range of strategies for supporting adults with dyslexia, particularly using computer technology.
