Analog Validation Study of Team Measures (Team_Measures)

Scientific Name: Homo sapiens Species: Human

When considering long-duration missions, it is acknowledged that there are many factors likely to influence crew performance, crew cohesion, and the interactions between crew and ground control. These factors have the potential to create interpersonal conflict, decrease morale, and/or create a negative environment for both individual crewmembers and the team itself. Many of these factors, if not addressed, may negatively influence cohesion among the crewmembers, interactions between the crew and ground control, and crew performance. In order to mitigate these negative consequences, it is essential to conduct research that will identify the most optimal measures and tools to monitor and assess these risk factors and their impact on these important team outcomes.

The main objective of this study was to create a standardized set of measures for team gaps and a normative database of team measures that are generalizable to both the astronaut population and the space flight context by utilizing high fidelity analog environments. This study provided the opportunity to assess crew performance, crew cohesion, and crew-ground interaction and identify which risk factors are most influential in relation to those three outcomes. In addition, it is designed to enrich the team literature and knowledge base of team research within the analog environment.

Specific Aims:

  1. Selection of initial team measures - measures will be selected based on present knowledge of important factors that relate to crew cohesion, crew performance, and crew-ground interaction as well as a consideration of acceptability and feasibility of implementing those measures selected
  2. Data collection at high fidelity analogs to create a team measure normative database - data will be collected at multiple analogs over time to create enough power to complete analyses (at least 25-30 teams)
  3. Analyze collected data to determine optimal set of team measures - will assess measures used and the robustness of the data
  4. Conduct an annual review to update measures used and/or analogs to be utilized

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
