This Small Business Innovation Research Phase II project from RSK Assessments, Inc. will expand and improve upon the test battery implemented for Phase I, including cross validation, examination of other behavioral scoring approaches (signal detection theory, Bayesian methods), other agents (viz., sleep loss) as well as the interplay of these methods on special purpose hardware and new software. Phase I examined the feasibility of conducting human performance-based fitness-for-duty (FFD) testing as an alternative to chemically-based testing. The testing method was brief and inexpensive, and the tests were stable and reliable. Using a multiple cut-off analysis varying proportion of tests passed, they yielded 98+% specificity (minimal false positives) with 80% sensitivity for high dosages of alcohol (and 60% for low). The new battery tightens security, running within self-contained kiosks and providing data encryption and access via smart card usage. Improved managerial control will be implemented within the test system, including test control and scheduling, data analysis methods, and reporting. Additional means of quantifying behavioral decrements will be obtained from sleep deprivation research, analyses of past alcohol research, and an "alpha" test site. Data from these sources will yield a better assessment model and refine calculations for tradeoff between test length, specificity, and sensitivity.RSK Assessments proffers a tool for testing human performance that could facilitate higher productivity in industrial plants, a means of testing employees while in the field, and reduction in worker on-the-job injuries.

RSK评估公司的小企业创新研究第二阶段项目将扩展和改进第一阶段实施的测试电池，包括交叉验证，检查其他行为评分方法（信号检测理论，贝叶斯方法），其他代理（即睡眠损失）以及这些方法在专用硬件和新软件上的相互作用。第一阶段研究了进行基于人体表现的适合工作测试的可行性，以替代基于化学的测试。该检测方法简单、成本低，检测结果稳定可靠。使用不同比例的测试通过了多重截止分析，他们获得了98%以上的特异性（最小的假阳性），高剂量酒精的灵敏度为80%（低剂量酒精的灵敏度为60%）。新的电池加强了安全性，在独立的信息亭内运行，并通过智能卡使用提供数据加密和访问。改进的管理控制将在测试系统中实施，包括测试控制和调度、数据分析方法和报告。将从睡眠剥夺研究、对过去酒精研究的分析和一个“阿尔法”测试地点获得量化行为下降的其他方法。来自这些来源的数据将产生更好的评估模型，并对测试长度、特异性和敏感性之间的权衡进行优化计算。风险风险评估提供了一种测试人类表现的工具，可以促进工业工厂提高生产率，是在现场测试员工的一种手段，并减少工人的工伤。
