Spaceflight Habitability Acceptability Questionnaire (SHAQ) Development and Validation (SHAQ)
Principal Investigator
Research Area:
Behavior and performance
Species Studied
Scientific Name: Homo sapiens Species: Human



The primary objective of this study was to develop and validate a Space Flight Habitability and Acceptability Questionnaire (SHAQ), to assess the behavioral health and performance impacts of volume, layout, and other design features of vehicles and habitats for long-duration exploration missions and other operational environments. A secondary objective was to characterize the behavioral health and performance risks associated with reduced volume and the lack of individual crew quarters in missions of shorter duration (up to 45 days). SHAQ responses served as the primary outcome metric to study the behavioral health and performance effects of habitat area layouts.

This study had the following specific aims:

  1. Empirically assess the initial sensitivity, construct validity, divergent validity, and concurrent validity of SHAQ over eight 45-day Human Exploration Research Analog (HERA) missions.
  2. Refine SHAQ based on the results of the HERA validation study.
  3. Draft a NASA Technical Report and/or manuscript for publication that (a) provides the results of SHAQ research and development efforts and (b) offers habitability recommendations for future deep space exploration missions.
  4. Author a SHAQ User Guide for public dissemination providing details on administration, scoring, and data management and interpretation.

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.
