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:
Investigators evaluated the quantitative responses to SHAQ as the primary measure. For concurrent validity, habitability-related items from the System Usability Scale (SUS) were administered during SHAQ sessions. Construct and divergent validity was assessed through measures of individual and team behavioral health and performance from complementary HERA investigations such as BHP Standard Measures in HERA. Operational acceptability was assessed during post-mission debrief interviews. Using a within-subjects repeated-measures design, the researchers collected SHAQ data from HERA 16 crewmembers in reference to the Sleep/Bedroom, Hygiene/Bathroom, Work/Office/Workshop, and Food Preparation/Kitchen/Galley habitat areas in the HERA operational environment, private hotel rooms, and individual home habitats.
SHAQ has high construct validity, internal consistency and reliability, concurrent validity, and discriminant validity (e.g., significantly higher facilitation of group activities in HERA Work/Office/Workshop and Food Preparation/Kitchen/Galley areas versus. Hygiene/Bathroom and Sleep/Bedroom areas; significantly lower ratings of privacy, comfort, and convenience in HERA versus. hotel). The resulting data and validated SHAQ instrument can be used to inform recommendations and thresholds on habitat size, layout, and design options to support individual and team behavioral health and performance in operational environments.
