“For applications such as the assessment of environmental stress or toxic agents, the metric requirements of performance test batteries include stability, reliability and sensitivity. However, fitness-for-duty applications present additional organizational and management laboratory conditions where the sensitivities of these test batteries are evaluated, the ratio of "treated" to "untreated" subjects is usually 50/50. However, in the workplace, the percentage of persons who are expected NOT to be impaired may be <5% and unless the accuracy of the psychological tests exceeds one minus the percentage NOT”

Kennedy, Robert S., Turnage, Janet J. and Dunlap, William P. (1993): Diagnosis of Alcohol Intoxication: Effectiveness of Cognitive and Neurovestibular Field Sobriety Tests. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 964-968.

“Tests from an automated performance test battery of cognitive tests and the standardized field sobriety tests (FST) used nationwide by law enforcement officers were administered in three experiments involving graded dosages of alcohol. In the first experiment, subjects were raised to one of four levels of alcohol dosage in four different sessions. In the second experiment, the descending branch of the blood alcohol level (BAL) curve was monitored from .15 BAL, and cognitive and motor performances were assessed by the Automated Performance Test System (APTS) and FST. In the third experiment, the ascending and descending limbs of the alcohol dosage curve were followed. Dose-response relationships were conducted and were statistically significant (p < .001) in all three studies for all but one test when evaluated singly. Using either test battery, composite scores could be employed to index degraded performance from elevated blood alcohol levels. The best single test was gaze nystagmus from the FST battery and the next best was code substitution from the cognitive battery. Taken singly, the individual tests ranged from 66% to 81% in terms of correctly detecting the dichotomous criterion of < 0.10 versus 0.10 BAC and above. These results are discussed in the context of standards setting for driving under the influence (DUI) and the use of behavioral tests to evaluate over-the-counter and prescription drugs.”

“A promising approach in recent years has been to develop measures of individual differences based upon componential cognitive theory to supplement or supplant traditional measures. Cognitive tests are developed to measure theoretically based mental operations which can be isolated by the computation of derived measures such as slope and difference scores. Along with others, we believe there are impediments to this approach due to unreliability of derived measures and lack of demonstrated statistical independence of tests of cognitive abilities. This paper describes a methodology for examining measures of individual differences in information processing skills that first follows the tenets of psychometric theory and then addresses cognitive theories. The approach is illustrated by demonstrating its application in tests representing four distinct cognitive paradigms which were administered repeatedly to subjects over three weeks. Recommended direct measures and derived scores for the four paradigms were examined in terms of their stabilities, retest reliabilities, and cross-correlations. Use of these procedures revealed that 1) derived scores had reliabilities near zero, and therefore, their correlations with other variables were equally low, rendering them of little use as individual difference variables, and 2) correlations between basic or nonderived scores were as high as their reliabilities would allow, suggesting that one common factor could account for the majority of the variance. The generality of this repeated measures paradigmatic approach to the identification of individual differences in human ability is illustrated by describing its application to the evaluation of a family of video games, tests of episodic memory, and visual contrast sensitivity at different spatial frequencies.”
