A correlation study of military psychological stress, optimistic intelligence quotient, and emotion regulation of Chinese naval soldiers

Psychological stress is closely related to the mental and physical health of soldiers. We explored the relationships between stress, optimistic intelligence, and emotion regulation in Chinese Navy personnel ( N = 452), who completed the General Information Questionnaire, the Psychological Stress Self-Evaluation Test, the Chinese Adult Optimistic Intelligence Quotient Questionnaire, and the Emotion Regulation Questionnaire in this cross-sectional study. Results show that stress was negatively correlated with perceived happiness and the ability to respond positively to negative events, and positively correlated with emotional regulation, cognitive reappraisal, and expressive suppression. These findings indicate that comprehensive measures using positive psychology techniques should be taken to reduce stress among naval soldiers to enhance their well-being and the military's combat readiness.
