| Resilience is the hot pot in positive psychology. It has been broadly defined as thecapacity of individuals exposed to a negative event to remain healthy and to cope flexiblywith challenges of life. Resilient people are typically characterized with optimism, positivecoping, and hardiness. These characteristics are associated with better physical and mentalhealth outcomes, and more positive adaptive behaviors to negative life events. In line withthe component of positive psychology, resilience is indicative of positive mental health.Studies have found that resilience had positive impact on individuals’ stress, not onlypresenting in its thinking and cognitive flexibility, adaptability of coping strategies andpositive evaluation to solve the problem, but also in how to interpret the positive andnegative life events. Fatigue is the subjective feeling that is closely related to stress, such aslong engagement in intense mental labor, excessive bother and sustained mood swingswhich would inevitablly lead to fatigue. Howerver, the degree of fatigue differs from timeand symptoms. Some researches indicate that psychological recovery process havesignificant correlation with physiological responses. The physiological response is parallelproduct of psychological and physiological recovery, and physiological response durationcan be the index of self recovery. Psychological stress and physiological responses havesignificant links, and the rise and drop of hormone level is the parallel product ofpsychological stress and physiological recovery.Surface warship soldiers are responsible for maritime tasks, and they are often in astate of stress when face harsh environment. They are in high concentration when work,which can lead to mental stress, reduced work efficiency. Hence their mental stress, fatigueand mental health directly affect the level of the combat effectiveness of the armed forces.How about the resilience state of military? What are the impact factors of resilience? Howto train and improve their psychological resilience? How about the effects that the resilience training on stress, fatigue and mental health? In the acute stress conditions, whichhormonal and neural mechanisms are involved in psychological resilience process? How tomeasure these physiological evidences and what are the indexes? These issues have notbeen reported. Therefore, this research selected warship soldiers as subjects. First evaluateand analyze resilience, personality, self consciousness, emotion, coping style, job stress,fatigue and mental health and other aspects by psychological tests, and then select subjectswith different resilience to carry out resilience training to understand the changes beforeand after training. Finally, explore resilience mechanism by the Trier Social Stress test andobserve dynamic changes of physiological indexes in military college students.Methods: This study firstly select warship soldiers as subjects, and evaluate andanalyze resilience, personality, self consciousness, emotion, coping style, job stress, fatigueand mental health and other aspects by psychological tests. Secondly, select50participantsin each of high and low individuals through interviews. Randomly divide them into thetraining group (n=45) and controlling group (n=50). Carry out resilience training to thetraining group, and understand the effect and physiological mechanism that the training totheir mental health, positive and negative emotion and heart rate variability. Finally, recruit160pariticipants from a medical university, using a screening questionnaire and interviewsto select11in each of high and low groups. Finally explore resilience mechanism by theTrier Social Stress test and observe dynamic changes of physiological indexes in militarycollege students. All data are used in SPSS17.0, AMOS7.0and Excel statistical softwareprocessing. The main statistical methods are: t test, chi-square test, analysis of variance andregression analysis.The main findings were as follows:1. Mental health, emotional stability, internal/external and resilience were able topredict individual’s stress level. Mental health and psychological stress had direct positiveimpact on work fatigue; The mental health affected psychological stress and had indirectpositive influence on work fatigue; Self-consciousness had indirect negative effect onfatigue by influencing on psychological stress and mental health.2. Resilience training can effectively improve warship soldiers’ resilience, increasetheir anti-stress ability and mental health level and reduce fatigue symptoms. Resiliencetraining can significantly improve positive emotion, keep the vagus nerve and sympathetic dynamic balance for people with lower resilience; Heart rate variability was positivelyaffected for people with higher resilience after resilience training.3. After the TSST experiment, an individual in a high state of psychological stress hasadverse reactions and subjective feelings such as obvious increases of tension, saliva sAA,GC and HRV, which increase with time, and that the subjective tension and state of mindwill gradually recover; the autonomic nervous system had a faster positive response againstthe acute stress in the high resilience group after the test, conducing to effective activeresponse. The autonomic nervous system under stress in the low resilience group respondedmore slowly, therefore stress recovery was more gradual, which did not conduce to thesubjects’ rapid and effective response.In conclusion, this study showed that:1. Warship soldiers’ resilience, personality, self-awareness are important factorsaffecting psychological stress and mental health.2. Work fatigue of warship soldiers had close relationships with their self-acceptance,self-concept, mental health and anti-stress ability.3. Resilience training can effectively improve warship soldiers’ resilience, increasetheir anti-stress ability and mental health level and reduce fatigue symptoms.4. The autonomic nervous system had a faster positive response against the acute stressin the high resilience group after the test, stress state of mind, the nervous system andhormone level recovery better than the low resilience group. |
