Objective:To explore the relationship between proactive personality, resilience and achievement motivation of military cadets, and to explore the mediating role of resilience between proactive personality and achievement motivation, as well as the moderating effect of cadets’leading ability on this mediating role.Methods:In this study, 109 military cadets were measured with proactive personality scale, Connor-Davidson resilience scale (CD-RISC) and achievement motivation scale. SPSS 26.0 was used for descriptive statistical analysis and correlation analysis.Results:①There was a significant correlation among the total scores of proactive personality, resilience and achievement motivation ( Ps<0.01). ②Proactive personality could significantly predict the level of achievement motivation ( a=0.454, P<0.001), and resilience could significantly predict the level of achievement motivation ( b=0.231, P=0.019). ③Resilience significantly mediated the relationship between proactive personality and achievement motivation ( c′=0.3, P=0.003). ④Cadets' leading ability moderated the effect of resilience on achievement motivation (index=0.338, 95% CI: 0.057 to 0.881). The mediating effect of resilience between proactive personality and achievement motivation was significant for cadets' leaders (Effect=0.381, 95% CI: 0.085 to 1.005), but not significant for other students (Effect=0.043, 95% CI: -0.069 to 0.252). Conclusion:The proactive personality of military cadets can affect the level of achievement motivation through psychological resilience, which is also moderated by cadre identity, suggesting that military education should improve the level of achievement motivation in many ways.

Objective:To investigate the level of psychological stress, anxiety and posttraumatic stress disorder (PTSD) of military medical students under the condition of normalized prevention and control of the epidemic.Methods:A total of 225 students from a military university were selected by random sampling method. Chinese perceived stress scale (CPSS), Perceived social support scale (PSSS), Self-rating anxiety scale (SAS) and PTSD Checklist-5 (PCL-5) were used to measure the mental health of the subjects and influencing factors. SPSS 26.0 was used to conduct independent sample t test and ANOVA analysis. Pearson correlation analysis was conducted, and multiple regression equation was used to further analyze the relationship between psychometric factors. Results:The SAS scores of 22.2% (50/225) of the subjects and PCL-5 scores of 30.7% (69/225) of the subjects reached the positive standard. The results of correlation analysis showed that the total score of PSSS was negatively correlated with CPSS ( r=-0.315, P<0.01), SAS ( r=-0.336, P<0.01) and PCL-5 ( r=-0.137, P<0.05) scores. The score of family support negatively predicted the level of psychological stress ( B=-0.595, P<0.001), anxiety ( B=-0.635, P<0.001) and PTSD level ( B=-0.769, P=0.006) of the students. Conclusion:Social support, especially family support, has a significant protective effect on psychological stress, anxiety and PTSD during the period of normalized prevention and control of the epidemic.

Objective:To investigate the relationship between resilience, perceived social support, and adaptability in military freshmen.Methods:A total of 195 freshmen were randomly selected from a military medical university. The Chinese version of Connor-Davidson Resilience Scale (CD-RISC), the Perceived Social Support Scale (PSSS), and a self-test questionnaire of college students' psychological adaptability were used to investigate their resilience, perceived social support, and adaptability. SPSS 26.0 was used to perform an independent samples t-test and a Pearson correlation analysis to analyze the differences in these scores between freshmen with different demographic characteristics and the correlation between these scores. By using the PROCESS plug-in, a structural equation model was used to analyze the mediating effect of resilience on the relationship between social support and psychological adaptation, which was further tested using the Bootstrap method. Results:The independent samples t-test showed that females had a significantly higher score of other support than males ( t = -2.05, P = 0.041), and student leaders had significantly higher scores of family support and other support, total score of social support, and score in psychological adaptability than other students (all P<0.05). The correlation analysis showed that there were significant positive correlations between the scores of PSSS and its each item, CD-RISC, and self-test of college students' psychological adaptability (all P<0.05). The structural equation model showed that resilience partially mediated the relationship between social support and psychological adaptation, and the Bootstrap method revealed a significant indirect effect (95%CI: 0.102-0.253). Conclusion:Resilience plays a partial mediating role between perceived social support and adaptability in military freshmen. They should be guided to correctly perceive external support and develop strong resilience.
7.Two year follow up of myopia cohort in central Jiangsu Province
Chinese Journal of School Health 2022;43(9):1298-1300
Objective:
Based on observational, longitudinal and intervention study of common diseases among students in Jiangsu Province, this paper presents the current progress of two year follow up of myopia cohort regarding the association between growth parameters with progression of myopia among children and adolescents in areas with rapid economic growth.
Methods:
This survey adopted the stratified cluster sampling method for school selection. The full automatic computer optometry (TOPCON RM800) was used to track myopia related parameters for all participants from 2019 to 2020 under the condition of mydriasis (compound topicamide eye drops). Relationship between growth parameters of children and adolescents and the incidence and progression of myopia was analyzed by using Cox regression multiple statistical model.
Results:
The myopia rates of students from grade 1 to grade 3 in 2019 were 5.4%, 21.5% and 37.3% respectively. After one year, the myopia rates of all school stages increased to 25.3%, 43.3% and 58.1% respectively( χ 2=53.59, 49.63, 32.52, P <0.01). The mean diopter of right eye and left eye after mydriasis were ( 0.30± 1.24/0.39±1.26)D in 2019 and (-0.33±1.54/-0.19±1.55)D in 2020, respectively based on Cox multiple regression results, age ( HR =1.21, 95% CI =1.09-1.34), naked eye vision ( HR =0.08, 95% CI =0.07-0.11), height ( HR =0.98, 95% CI =0.97-0.99) showed a strong correlation with the incidence and progression of myopia( P <0.05).
Conclusion
Myopia is growing rapidly in the central region of Jiangsu Province. It is suggested that diopter, axial length, naked eye vision, age, height and other indicators should be included in the refractive archives of children and adolescents in the region.
