![]() ![]() Frankenburg has replied to such criticism by pointing out that the Denver Scale is not a tool of final diagnosis, but a quick method to process large numbers of children in order to identify those that should be further evaluated. ![]() This revised definition of the Denver's function remains commensurate with what screening tests are designed to do: sort those who probably have problems from those who probably don't. Thus standards for screening test construction still apply to the Denver. Although the instrument has proven reliability, it was not constructed on a large, current, nationally representative sample. It has not been studied for validity (given alongside diagnostic measures to view their relationship or researched for the kinds of problems it may or may not detect). Studies by other researchers showed it to detect only about 50% of children with disabilities, although its specificity in identifying normally developing children is high (when questionables are grouped with normal scores) and the converse when questionable scores are grouped with abnormal results.Īs a consequence, the measure was not studied by its authors for the most critical attribute of any screen, its accuracy. ![]()
