To explore the mediating role of personality traits and mental resilience in the relationship between competence and job performance among junior officers.

Competency Inventory, 25-Item Connor-Davidson Resilience Scale (CD-RISC-25), short version of the Big Five Personality Scale [Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI)], and Chinese Perceived Stress Scale (CPSS) were used as assessment tools to survey 586 junior officers selected by convenience sampling.

① For junior officers, their competence was positively and moderately correlated with job performance, openness personality, extroversion personality, agreeableness personality, responsibility personality, and total score and score for each dimension of psychological resilience (P < 0.01), and negatively and moderately correlated with neuroticism personality (P < 0.01). ② Significantly mediating role was observed in personality and mental resilience for competence and job performance in junior officers, with an indirect effect of 20.68% for personality and 33.18% for mental resilience.

Personality and mental resilience mediate significantly between competence and job performance in junior officers. Our findings provide a theoretical basis for the action mechanism of competence in job performance for junior officers.

To investigate the effects of group identification on death anxiety among military medical students and the chain mediating effects of self-esteem and collective self-esteem.

Cluster sampling was conducted to survey the students in a military medical university in July, 2021, and finally survey data from 360 participants were collected through WeChat Mini Program, Questionnaire Star. The Questionnaires included Templer Death Anxiety Scale (T-DAS), Organizational Identification Questionnaire, Rosenberg Self-Esteem Scale-Revised (RSES-R), Collective Self-Esteem Scale and a self-designed general information questionnaire.

①The score of death anxiety in the participants ranged from 1.00 to 4.33 (M=2.60). ②The scores of group identification, self-esteem and collective self-esteem were negatively correlated with death anxiety (r=-0.56~-0.21, P<0.01). Significantly positive correlations were observed in any 2 scores among the above 3 scores (r=0.42~0.68, P<0.01). ③Group identification significantly negatively predicted death anxiety (b=-0.21, SE=0.02, P<0.001). ④There were 3 mediation effects between group identification and death anxiety: group identification→self-esteem→death anxiety, group identification→collective self-esteem→death anxiety, group identification→self-esteem→collective self-esteem→death anxiety, with a total indirect effect of -017.

Group identification can negatively predict death anxiety among military medical students, and self-esteem and collective self-esteem play a chain mediating role between them.

To construct a group psychological training for junior officers based on competency model and explore its intervention effect on competency and mental health of junior officers.

Delphi method was used to construct a group psychological training program for junior officers based on competency model. A total of 63 junior officers were subjected with convenience sampling during October and November 2023. According to the principle of randomized controlled experimental design, the participants were divided into experimental group (n=30) and control group (n=33). The experimental group was given our group psychological training program for totally 8 sessions, 90~120 min per session, 2 sessions per week, while the control group received no such training. Competency scale, 12-item general health questionnaire (GHQ-12), Chinese perceived stress scale (CPSS), and Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) were used to assess the 2 groups before and at the end of intervention.

① The results of the 2 rounds of expert consultation showed that the total recovery rate was 100%, the expert authority coefficient was 0.87, the Kendall's coordination coefficients (ω) of the 2 rounds of expert consultation were 0.102 (P < 0.001) and 0.410 (P < 0.001), respectively, with a coefficients of variation of < 0.3, indicating reliable expert consultation. ② The results of post-intervention time main effect indicated that the total score of competence (P < 0.001), extroversion score (P < 0.05) and responsibility score (P < 0.01) were significantly higher, but the total score of GHQ-12 was obviously lower in the experimental group than the control group (P < 0.001). ③ The results of post-intervention group main effects revealed that the extraversion score of the experimental group was significantly higher than that of the control group (P < 0.01). ④ The results of the post-intervention time × group interaction displayed that the experimental group had notably higher total competency score (P < 0.01), job performance score (P < 0.05), extraversion score (P < 0.05), agreeableness score (P < 0.001) and responsibility score (P < 0.01), but lower total GHQ-12 score (P < 0.01) than the control group.

Competency-based modeling group psychological training for junior officers can significantly enhance the competency, strengthen the extroversion, agreeableness and responsibility in personality traits, and thus improve job performance for them.

To analyze the research status of group psychological training in the field of psychological training using bibliometric methods, predict future research hotspots and development trends, and summarize the shortcomings in group psychological training.

Chinese literature related to group psychological training from 2003 to 2022 was retrieved from the China National Knowledge Infrastructure（CNKI）, Wanfang Data Knowledge Service Platform（Wanfang）, and the VIP Chinese Science and Technology Periodical Database. Qualified literature was selected using NoteExpress V3.9, and the publication volume and journals of the qualified literature were statistically described using Excel. VOSviewer 1.6.18 was used to draw a co-authorship density view of core authors, and CiteSpace 6.1. R6 was used to draw co-occurrence maps, keyword clustering, timeline, and burst analysis for visualization analysis.

In the 3 major Chinese databases, a total of 4 757 qualified articles were included. The overall publication volume showed a slow growth trend, with medical and educational journals being the main publication outlets. Journal of Chinese Health Psychology got the top in highest number of publications, reaching 171 articles. A total of 173 core authors and representative research teams such as Yang Guoyu, Li Na, Wang Ping and Zhang Yan were identified. Co-occurrence and clustering analysis of keywords showed a focus on empirical intervention research. Keyword burst analysis indicated that themes such as quality of life, psychological state, social functioning, negative emotions, and psychological resilience were the research directions of group psychological training. Group intervention research emerged as a research hotspot, representing the future development trend of psychological training.

The research hotspots of group psychological training mainly include group psychological counseling, group psychological therapy, group psychological consultation, and group psychological training. They are reflected in areas such as college students, mental health education, positive psychology, anxiety, depression, interpersonal relationships, and psychological qualities, and have obtained certain stage achievemets. However, further exploration and improvement are still needed in theoretical research, research methods, long-term tracking and evaluation, integration of theory and practice, and interdisciplinary cooperation.

To explore the change features over time in anxiety, depression, insomnia, and professional identity in new recruits, and investigate the change rules in correlation over time of professional identity with anxiety, depression, and insomnia.

A total of 272 new recruits were surveyed twice with Patient Health Questionnaire-9（PHQ-9）, Generalized Anxiety Disorder-7（GAD-7）, Athens Insomnia Scale（AIS）, and Military Professional Identification Scale.

①Over time, the GAD-7, PHQ-9 and AIS scores were decreased [Z（based on the negative rank）=-5.134, -4.991, -5.915, P<0.001], but that of professional identity was increased [Z（based on the positive rank）=-4.392, P<0.001]. ②The correlation of professional identity with anxiety, depression and insomnia was gradually decreased over time, and the interaction effects of professional identity by training time on anxiety, depression and insomnia were significant（Wald Chi-square=6.335, 10.487, 4.147, P<0.05）.

During the new training period, anxiety, depression, insomnia are decreased, and professional identity is increased over time. The correlation of professional identity with anxiety, depression and insomnia is declined during the training among the new recruits.

To develop a training scheme of psychological training for the developmental group of army sergeants and explore the intervention efficacy of the scheme on their psychological health.

Delphi method was used to construct a psychological training program for the developmental group of army sergeants. Eighty army sergeants were recruited as the research subjects, and randomly divided into an experimental group and a control group, with 40 individuals in each group. The experimental group received 10 sessions（90~120 min per session）of group psychological training based on our training program, while the control group received regular psychological health education and political education. The training effects were evaluated using the Self-Rating Depression Scale, Generalized Anxiety Disorder Scale, Psychological Resilience Scale, Perceived Social Support Scale, Brief Coping Style Questionnaire, Perceived Stress Scale, Big Five Personality Inventory, and Self-Evaluation Questionnaire for Group Psychological Training before and in 1 week after the training.

①Our training program consisted of 3 units and 8 themes. The first unit focused on self-development, including self-awareness, self-acceptance, and self-growth. The second unit focused on emotion and stress management, including emotion regulation and stress management. The third unit focused on social development, including interpersonal communication, relationship adjustment, and career planning. ②After the training, the experimental group had significantly decreased scores of PHQ and GAD（P<0.05）, and the PHQ score was obviously lower than that of the control group（P<0.05）. ③The total score of psychological resilience, as well as the sub-scales of toughness, strength, and optimism, significantly increased in the experimental group（P<0.05）, and were significantly higher than those of the control group（P<0.05）. ④After the training, the dimension of friend support in social support was significantly increased in the experimental group（P<0.05）and it was notably higher than that of the control group（P<0.05）. ⑤The positive coping score was significantly increased in the experimental group after the training（P<0.05）. ⑥The extraversion dimension of the Big Five Personality Inventory was significantly increased in the experimental group after the training（P<0.05）.

Our training scheme for army sergeants can effectively alleviate anxiety and depression, increase positive coping styles, enhance psychological resilience, friend support in social support, and extraversion in the Big Five Personality.

To establish a group psychological training program for improving the psychological capital of recruit training squad leaders, and to explore its intervention efficacy for their psychological capital and work engagement.

Delphi method was used to construct a psychological training program to improve the psychological capital of recruit training squad leaders. With convenient sampling, 71 recruit training squad leaders were enrolled from April 1 to May 30, 2023, and then randomly divided into experimental group（n=35, 6 times of psychological training, for 2 hours each time, twice a week）and control group（n=36, routine training）. Pre-test, post-test and one-month follow-up measurements were conducted using Psychological capital questionnaire（PCQ）and Utrecht work engagement scale（UWES）in both groups.

①The expert authority coefficient（Cr）of the 2 rounds of expert consultation was 0.905, the positive coefficient was 100%, and the Kendall coordination coefficient was 0.142 and 0.260（P<0.001）. The psychological capital group training program had 6 first-level indicators and 24 second-level indicators. ②After the intervention, the group-by-time interaction between the experimental group and the control group showed that the total scores of psychological capital and work engagement were significantly higher in the experimental group than the control group（Wald Chi-square=60.341, 101.410; P<0.001）.

Group training program can significantly improve the psychological capital and enhance work engagement for recruit training squad leadser.

To construct a career management index system for army mental health personnel in order to promote the development of mental health personnel team.

A total of 82 mental health personnel were selected for semi-structured interviews. Colaizzi analysis was used for this qualitative research, and Delphi expert consultation was employed to establish a career management index system for army mental health personnel.

The effective recovery rate of the questionnaires for the 2 rounds of expert consultation was 100%, with a recommendation ratio of 70% and 35% respectively, and the authority coefficient of the expert consultation was 0.86. The values of Kendall's concordance coefficients for each level ranged in 0.186 to 0.240 and 0.132 to 0.162, respectively（all P<0.01）, and the coefficient of variation of each indicator was <20%. Finally, a career management index system for military mental health personnel was constructed, specifically including 4 first-level indicators（organizational mechanism, management content, implementation path and effect evaluation）, 13 second-level indicators and 36 third-level indicators.

Our constructed career management index system for army mental health personnel has high authority and scientificity.

To investigate the intervention effect of group psychological training for cadets on individual wellbeing literacy, cognitive reassessment, mental toughness, and subjective well-being based on wellbeing literacy theory.

A total of 116 undergraduate cadets were subjected from a military university with whole-group sampling, and according to their mock platoons of cadet corps, they were divided into experimental group（n=58, 7 times of group psychological training, for 90~100 min each time, twice a week）and control group（n=58, no such training）. Wellbeing Literacy 6 item scale（Well-Lit 6）, General Well-being Schedule（GWBS）, Cognitive Rating Scale of the Chinese version of the Emotion Regulation Questionnaire（ERQ）, and Connor-Davidson resilience scale（CD-RISC-10）were used to assess the 2 groups of participants before（T1）, immediately after（T2）, and 1 month after（T3）the training, respectively.

There were no statistical differences in demographic information and each psychological index between the 2 groups before training（P>0.05）. Significant grouping×time interaction effects were observed in total wellbeing literacy score（P<0.05）, cognitive reassessment score（P<0.001）, psychological resilience score（P<0.001）, and total subjective well-being score（P<0.001）.

Group psychological training for military cadets based on wellbeing literacy theory can enhance the wellbeing literacy of military cadets, improve their cognitive reassessment strategies, elevate their psychological resilience, enhance their subjective well-being, and beneficially improve their mental health.

To analyze the miRNAs expression profile of the amygdala of mice with chronic stress-induced anxiety disorder and explore the key miRNAs and their possible targets.

Eight-week-old C57BL/6 male mice with body weight ranging from 18 g to 22 g were randomly divided into anxiety disorder group（n=12）and control group（n=12）. The anxiety disorder group have been restrained in narrow space for 10 consecutive days（2 h/d）to create a mouse model of anxiety disorder, while the control group accepted no stress. After the modeling was completed, the anxiety-like behavior of mice was detected by elevated cross maze experiment, open field experiment and light and dark box experiment. Transcriptome sequencing was used to detect the expression of miRNAs in the amygdala of mice between the anxiety disorder group and the control group. The target genes of differentially expressed miRNA were predicted by miRanda. Functional annotation was conducted by Gene Ontology（GO）analysis, and signal pathway analysis by Kyoto Encyclopedia of Genes and Genomes（KEGG）database to explore the important miRNAs in the amygdala that play a role in anxiety disorders. The key miRNAs explored before were quantitatively detected by RT-qPCR.

The anxiety disorder group showed significant anxiety-like behavior in elevated cross maze, open field and light and dark box experiments. Compared with the control group, the mice in the anxiety disorder group had 35 differentially expressed miRNAs in the amygdala. The results of GO function analysis showed that the predicted target genes were significantly enriched in the functions related to plasticity regulation of synaptic, while the results of KEGG signal pathway analysis showed that the differential miRNA predicted target genes were obviously enriched in signal transduction and cancer-related signaling pathways. The expression of miR-128-2-5p in the anxiety disorder group was significantly decreased（P<0.05）, while the expression of miR-10b-5p, miR-200a-3p, miR-200b-3p and miR-429-3p in the anxiety disorder group were significantly increased（P<0.05）. Among them, the extents of changes of miR-128-2-5p and miR-200a-3p were consistent with the transcriptome sequencing results.

The key miRNA molecule miR-128-2-5p and its downstream target genes bmpr2, irf6 and rbfox3 may become the potential therapeutic targets for anxiety disorders.
