INTRODUCTION: Long-duration space missions introduce stressors that can disturb the affective states of astronauts (e.g., isolation, workload). However, studies in or space-analog environments struggle to find a consensus on impact these stressors. Also, there is lack research using multiple measures assess conditions positive and negative physiological parameters). More needed understand psycho-physiological mechanisms during long-duration space-like missions. Our study was conducted confinement (SIRIUS-19). Throughout mission, we assessed variations subjective parameters. We expected interindividual variability, with transitory chronic changes psychological dimensions states. METHODS: Six subjects (three men/three women; four Russians/two Americans; age = 33.83 ± 6.37) performed protocol once month 4-mo confinement. Subjects completed various psychometric scales about their (Self-Assessment Manikin, Positive Negative Affective Schedule) provided hair cortisol samples. Due small sample size, only individual values descriptive statistics were used. RESULTS: Psychometric remained stable. Hair levels increased at beginning mission (from 31.79 18.05 pg · mg −1 62.25 31.99 ). Most measurements showed variability. DISCUSSION: The relatively stable throughout mission. initial increase attributed an adaptation phase crew. No variation seems be related this phase. results indicate effective Pauly J, Langlet C, Hainaut J-P, Yusupova A, Bolmont B. insights from . Aerosp Med Hum Perform. 2025; 96(5):436–442.
