Abstract The purpose of the present study was to explore personal growth and changes in values in crewmembers of two spaceflight simulation studies of different duration. The crewmembers were from different nations and of different cultural backgrounds. Stress-Related Growth Scale and Portrait Values Questionnaire were administered to crewmembers of SIRIUS-17 (17 days, n = 6; 3 women) and SIRIUS-19 (120 days, n = 6; 3 women) studies at baseline and debriefing measurements. The results show personal growth in all crewmembers in both experiments, with perceived growth higher than anticipated growth. The highest personal growth was reported in the social area regardless of experiment duration, gender, and background culture type, followed by the cognitive/affective area. An increase in the significance of universalism, benevolence, self-direction, tradition, and stimulation (mainly for men) was observed. The study extends existing knowledge by a more detailed insight into the different aspects of social and cognitive/affective personal growth and significance of particular values in persons exposed to demanding conditions.
