Objective First popularized as neurasthenia in the late 1800s by American George Beard, asthenia has been viewed by Russian psychologists and flight surgeons as a major problem that affects cosmonauts participating in long-duration space missions. However, there is some controversy about whether this syndrome exists in space; this controversy is attributable in part to the fact that it is not recognized in the current American psychiatric diagnostic system. Methods To address this issue… Expand
Cultural differences in patterns of mood states on board the International Space Station
Abstract Based on our previous studies of astronauts and cosmonauts, we hypothesized that the patterning of mood states among International Space Station (ISS) crewmembers would vary by culture,Expand
Perspectives on Asthenia in Astronauts and Cosmonauts: Review of the International Research Literature
TLDR
The aim of this report is to address one of the recommendations made by that panel, specifically the recommendation that the literature on asthenia should be evaluated (possibly as a psychological or psychosomatic / psycho-physiological analogue of chronic fatigue syndrome). Expand
Different Perspectives on Asthenia in Astronauts and Cosmonauts: International Research Literature
TLDR
This report was a collaborative international work effort focused on the evaluation and determination of the importance of continuing research on asthenia as a possible psychological problem that might affect the optimal psychological functioning among crewmembers during long-duration space flight missions.

Psychosocial interactions during ISS missions
Abstract Based on anecdotal reports from astronauts and cosmonauts, studies of space analog environments on Earth, and our previous research on the Mir Space Station, a number of psychosocial issuesExpand

TLDR
Important psychosocial issues involving tension, cohesion, leader support, and displacement of negative emotions were evaluated in a 4 1/2-year study involving five U.S. and four Russian Shuttle/Mir space missions, and there was strong evidence to support the hypothesized displacement of tension and negative emotions from crewmembers to mission control personnel and from missions control personnel to management.

DIFFERENCES IN PATTERNS OF MOOD STATES AMONG RUSSIAN AND AMERICAN SPACE STATION CREWS
Based on our previous studies of astronauts, cosmonauts, and Russian psychiatric patients, we hypothesized tha t the patterning of mood states among space program personnel would vary by culture,Expand
Development and Validation of the Cognition Test Battery for Spaceflight.
TLDR
The first normative and acute total sleep deprivation data on the Cognition test battery are described as well as several efforts underway to establish the validity, sensitivity, feasibility, and acceptability of Cognition. Expand
Behavioral and psychological issues in long-duration head-down bed rest.
TLDR
Psychological support and training provided to both subjects and study personnel have successfully improved the well being of study participants, indicating Behavioral health services are indispensable to long-duration head-down bed rest studies. Expand
Behavioral Health and Performance Support
This chapter reviews the stressors and countermeasures that affect crew behavioral health and performance during space flight. This review is based on the experiences of crewed space flight in bothExpand
Human cognitive performance in spaceflight and analogue environments.
TLDR
The available evidence fails to strongly support or refute the existence of specific cognitive deficits in low Earth orbit during long-duration spaceflight, which may be due in large part to small numbers of subjects. Expand

TLDR
Although much is known about psychiatric issues related to long duration manned space travel, more empirical work needs to be done during actual space missions. Expand
Human interactions in space: results from Shuttle/Mir.
TLDR
There was little support for the presence of a moderate to strong time effect that influenced the space crews, and crewmembers perceived their work environment differently from people on Earth, and they demonstrated equanimity in mood and group perceptions, both in space and on the ground. Expand
Crewmember communication in space: a survey of astronauts and cosmonauts.
A total of 54 astronauts and cosmonauts returned questionnaires which addressed various aspects of crewmember communication in space. All respondents believed that crewmembers should be fluent in oneExpand
Social and cultural issues during Shuttle/Mir space missions.
TLDR
Findings related to social and cultural issues from a NASA-funded study conducted during several Shuttle/Mir space missions indicate that American subjects reported more dissatisfaction with their interpersonal environment than their Russian counterparts, especially American astronauts. Expand
Crewmember and ground personnel interactions over time during Shuttle/Mir space missions.
TLDR
The absence of moderate to strong support for the biphasic model suggests that crewmember interpersonal functioning does not depend appreciably on 1st half/2nd half time effects and countermeasures need to be developed to deal with this phenomenon in both crewmembers and mission control personnel. Expand
Interpersonal and cultural issues involving crews and ground personnel during Shuttle/Mir space missions.
TLDR
In future long-duration space missions, countermeasures should focus on providing support for crewmembers from a culture in the minority, and crews should include more than one representative from this culture. Expand
