Supplementary file 1_A culture-informed psychological model for elite Chinese mountaineers: an exploratory study and development of a performance-based assessment tool.docx

IntroductionThe psychological determinants of performance and survival in elite high-altitude mountaineering remain poorly understood, partly due to the difficulty of recruiting substantial samples from this highly specialized population and the limited applicability of Western-derived frameworks to culturally distinct cohorts such as Chinese mountaineers. This study aimed to develop and preliminarily examine a culture-informed psychological model for elite Chinese mountaineers and to establish a performance-based evaluation framework.
MaterialsUsing a cross-sectional exploratory design, 15 psychological indicators were assessed in 84 Chinese mountaineers (53 elite; 31 non-elite) using validated Chinese-language instruments. Independent-samples t-tests were conducted to identify performance-discriminant indicators, and principal component analysis (PCA) was employed to explore the underlying psychological component structure.
ResultsElite mountaineers scored significantly higher on 10 indicators, including Perseverance (d = 0.66), Goal Clarity (d = 0.56), and Anxiety Control (d = 0.58) (all p < 0.05). PCA yielded a four-component structure comprising Willpower (39.13% of explained variance), Psychological Skills (29.49%), Anxiety Level (17.77%), and Tenacity (13.62%). A weighted composite score derived from normalized component loadings significantly differentiated elite from non-elite mountaineers (Fisher–Freeman–Halton exact test, p < 0.001).
ConclusionAs an exploratory model-development study, these findings provide preliminary evidence for a willpower-centered, contextually grounded psychological framework and its discriminative utility, offering a preliminary basis for research and training-oriented psychological profiling in elite high-altitude mountaineering.
