Psychological evaluation and support during EXEMSI. Experimental Campaign for the European Manned Space Infrastructure.

The aim of this study was to investigate changes in the psychological state of the crew members and the needs for psychological support during prolonged isolation. For the purpose methods employed that have been widely used in psychological evaluation during Soviet spaceflights. Communication between Commander and Crew Interface Coordinator (CIC) was analyzed. Crew disposition was observed and analyzed for information about the process of group formation and the role of each crew member in this process. Operation of the CIC's was investigated for evidence of a psychological support function. During isolation certain adaptive changes in communication took place: (1) use of unplanned contacts and intensive contacts with a preferred ground crew member, (2) resistance to penetration in the life of the crew (increase of aggressive statements and self-justifications, reduction of report length and claims), and (3) closing communication to "outsiders" by using a special code and decreasing discussion of problems. A process of group formation was noted in the course of isolation, but the final structure of the group was not stable. The relations of subjects B, D and G were crucial in the creation of an effective crew. The woman in the crew was never involved in conflicts and acted as a peacemaker. The crew regarded the communication channel between Commander and CIC as belonging to the entire crew for expressing feelings about crew relations, administration and services, and the CIC can provide needed psychological support, confirming earlier experience from Soviet simulated and actual spaceflights.
