DEVELOPMENT OF SURROGATE METHODOLOGIES FOR OPERATIONAL PERFORMANCE-MEASUREMENT - EMPIRICAL-STUDIES

A series of studies is described demonstrating the feasibility of link ing reliable surrogate performance tests to real-life measures of perf ormance. First, we illustrate dose equivalency, where deficits in comp uterized performance tests were related to graded dosages of alcohol a nd where prediction equations of blood alcohol level were established. Secondly, surrogate criteria composed of standardized aptitude tests (known to be predictive of operational performances) were administered to a sample tested on the same computer-based cognitive tests. This p erformance loss, in connection to alcohol, was indexed to cognitive pe rformances on the computer tests through their composite relation to i ntelligence tests. These laboratory-based relations were then linked t o several studies of real-world performances by applying the integrati ve surrogate metric. An explanation is given of how the composite is d eveloped and used to form units that are common from study to study an d familiar to the reader.
