SBIR Phase II: A Computerized Test Battery to Evaluate Workplace Stresses

这个小企业创新研究第二阶段项目从RSK评估，公司。将扩展和改进第一阶段实施的测试组合，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的表现的适合工作（FFD）测试作为替代基于化学的测试的可行性。 该方法简单、成本低，试验稳定可靠。 使用多个截止值分析不同比例的测试通过，他们产生了98+%的特异性（最小的假阳性），高剂量酒精的敏感性为80%（低剂量为60%）。 新电池加强了安全性，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。 将在测试系统内实施改进的管理控制，包括测试控制和调度、数据分析方法和报告。 量化行为减少的其他方法将从睡眠剥夺研究、过去酒精研究的分析和“阿尔法”测试点获得。 从这些来源的数据将产生一个更好的评估模型和完善的计算之间的权衡测试长度，特异性和sensitivity.RSK评估提供了一个工具，用于测试人类的表现，可以促进更高的生产力在工业厂房，一种手段，测试员工，而在现场，并减少工人的工伤。

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.
