Comparing, Combining and Converting Screening Instruments

  • A. J. Larner


This chapter examines various methods of comparing, combining and converting various screening instruments. Methods of comparing cognitive scales include not only the standard measures of discrimination considered in previous chapters but also weighted comparison and effect size, as well as meta-analysis. The diagnostic utility of combinations of scales, both cognitive and non-cognitive, is also considered, as well as ways to make approximate conversions between the scores of different screening tests.
