The Association between Psychological Stability and Successful Interpersonal Interaction in Isolation: Theoretical and Methodical Aspects

Abstract

Theoretical definitions of psychological stability of an individual are examined with the emphasis on the main components of this complex characteristic. The focus is laid on the aspects of adaptation in a team, in particular, the effect of psychological stability on the preferred styles of interpersonal interactions in isolation and confinement. We outline a three-stage psychological stability analysis at the cognitive, physiological, and behavior levels and describe the suite of tests used at the Institute of Biomedical Problems in the experiments with simulation of some spaceflight factors (2011–2016) to collect objective data on the strength and dynamics of personal psychological stability and its relevance to successful interaction within an isolated group.
