Multi-measurement Approach to Training and Assessment in Various Environments

We propose that a multi-modal measurement approach which integrates data from a variety of sources is critical to forming a comprehensive understanding of human behavior or performance in various environments (e.g., work environments) for various applications (e.g., a training or treatment program). Moreover, the use of a multi-modal measurement technique can afford flexibility in measurement across those environments and selecting the most relevant measurement tools to minimize the technical footprint required for the assessment. The value of the multimodal approach to measurement is the ability to construct a more comprehensive assessment of human behavior within a specific context for a variety of different applications with minimal invasiveness. Two applications of this method will be discussed: (1) a pain management system for older adults with Osteoarthritis (Pain Management and Tracking System for Osteoarthritis, Pain MATS-OA), and (2) a cognitive readiness assessment system for teams in operational military environments (Tool for Rapid Assessment of Cognitive Readiness in Teams, TRACR-T).

Pain MATS-OA: Aptima proposed to design Pain MATS-OA to integrate multiple data sources to measure behavioral and affective factors previously shown to affect pain levels (Parmelee, 2005) (system-based, e.g., from an electronic diary; sensor-based, e.g., ActiGraph). With information from various sources, Pain MATS-OA can capture an accurate and multi-dimensional picture of an individualís pain experience, daily activities, behaviors, mood, and affect, but with minimal invasiveness or reliance on delayed recall which declines with aging Craik, F.I.M. & Salthouse, T.A. (2008). Visualizations based on these measures can be designed to enable users (older adults with OA knee and hip pain and healthcare providers) to easily identify relationships between pain and mediating factors which can be used to (1) identify lifestyle changes that reduce pain levels (2) actively involve patients in the identification of trends in their pain experience and hence decisions about strategies to manage pain, (3) and track patient progress and effectiveness of treatment programs.

TRACR-T: Aptima is currently researching and developing TRACR-T which will be designed to assess a team's cognitive readiness to perform a mission or task. TRACR-T will collect and aggregate instantaneous state measures (e.g., neurophysiological, physiological) at the individual and team levels and integrate those measures with historical information about the team, performance data from the team (e.g., communications, accuracy, reaction time), and from each member to assess cognitive readiness.
