Reliability and validity of the Chinese version of the Psychological Climate Scale among nuclear emergency responders

Objective: To translate and culturally adapt the Psychological Climate Scale into Chinese and to examine its reliability and validity among nuclear emergency responders, thereby providing a reliable instrument for assessing their organizational psychological climate. Methods: The Brislin translation-back-translation model was employed to translate and culturally adapt the Psychological Climate Scale. Following expert consultation and a pilot study, a Chinese version of the scale was developed. A total of 286 nuclear emergency responders from three provinces (Beijing, Hunan, and Yunnan) were recruited to evaluate the reliability and validity of the scale. Results: values of 0.944 and 0.929 for "Supervisor Support and Work Value" and "Organizational Constraints and Emotional Expression," respectively. The split-half reliability was 0.951, and the two-week test-retest reliability coefficient was 0.782. Content validity was satisfactory (I-CVI: 0.900-1.000; S-CVI/Ave: 0.953). Exploratory factor analysis supported a two-factor structure (KMO = 0.945), explaining 68.267% of the total variance. Conclusion: The Chinese version of the Psychological Climate Scale demonstrated good reliability and validity among nuclear emergency responders. The instrument provides a useful tool for assessing psychological climate in this population and may offer an empirical basis for organizational support strategies and targeted psychological interventions.
