Development and validation of the psychological stability scale for special operations personnel in China.
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Special operations personnel are consistently exposed to high-stress, high-risk, and hazardous occupational environments due to the unique operational demands. To effectively cope with these stresses and ensure successful task execution, high levels of psychological stability are required of them. However, specific assessment tools are lacking to evaluate the psychological stability of special operations personnel. Based on grounded theory, this study proposed a theoretical model of psychological stability among special operations personnel and developed a corresponding measurement scale. Methods: A mixed-methods approach integrating both qualitative and quantitative research was adopted across three studies. Study 1 included in-depth interviews conducted with 30 special operations personnel. Grounded theory was applied to analyze the dimensions of psychological stability, and the Delphi consensus was used to determine the specific connotation of each dimension of psychological stability. Study 2 focused on developing and refining the scale through content validity analysis, item analysis, item-total correlation analysis and exploratory factor analysis. Study 3 validated the scale using confirmatory factor analysis and conducted reliability and validity testing. Results: Study 1 identified seven dimensions of psychological stability, including self-confidence, conscientiousness, equanimity, rationality, disturbance tolerance, stress tolerance, and frustration tolerance. In Study 2, a 29-item psychological stability scale (PSS) with five dimensions was developed, including self-confidence, conscientiousness, equanimity and rationality, disturbance tolerance, stress and frustration tolerance. Study 3 demonstrated that the scale exhibited strong reliability and validity across different samples. Discussion: This study innovatively revealed the dimensions of psychological stability in special operations personnel and developed a valid and reliable measurement tool.
