Objective To explore the effects of self-management strategy on cancer-related fatigue patients though meta-analysis. Methods Randomized controlled trials(RCTs) of self-management strategy on cancer-related fatigue were searched in databases including Cochrane Library, Web of Science, PubMed, Elsevier, CBM, CNKI, WanFang. After two researchers evaluated the literature quality, ReviewManager 5.3 was used to analyze. Results Twelve RCTs were retrieved and considered as eligible, using The Brief Fatigue Inventory (BFI),Cancer Fatigue Scale (CFS), Function Assessment of Cancer Therapy-Fatigue (FACT-F), Checklist Individual Strength (CIS), Multidimensional Fatigue Inventory (MFI). According to the Meta-analysis, cancer-related fatigue could be effectively improved though self-management strategy. Two classification data-the results of BFI measurement RR=0.75 (95％CI: 0.70-0.81, P<0.01), continuous data-SMD=-0.96 (95％CI:-1.81--0.11, P=0.03), CFS measurement results, WMD=-10.69 (95％CI:-12.37--9.01, P<0.01), FACT-F,CIS,MFI measurement results, SMD=-0.22 (95％CI:-0.40--0.04,P=0.01). Conclusions Using self-management strategy can significantly relieve cancer-related fatigue, and more high quality researches were needed to support the findings.

Objective:To investigate the status of clinical nurses′ professional identity, structural empowerment and psychological empowerment, analyze the correlation between professional identity and structural empowerment and psychological empowerment, and establish a multiple stepwise regression model to discuss the dependence between professional identity and structural empowerment and psychological empowerment in clinical nurses.Methods:A total of 1 008 clinical nurses from Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University were selected as the subject by using the convenience sampling method. The General Information Questionnaire, Professional Identity Scale, Conditions of Work Effectiveness Scale, and Psychological Empowerment Scale were used to questionnaire.Results:The professional identity of nurses was at medium level (104.49±19.54), the total scores of structural and psychological empowerment of nurses were 60.09±13.49 and 42.59±7.31. Correlation analysis showed that the total score of professional identity of clinical nurses was positively correlated with the total score of structural empowerment, psychological empowerment and theirs dimensions ( r values were 0.436-0.715, P<0.01). Multivariate stepwise regression results showed that the nurse working years, health status self-assessment, formal empowerment, informal empowerment, work meaning, self-efficacy, work influence was the main influencing factors of nurses professional identity, which explained 60.5% of the total variation. Conclusions:Nursing managers should focus on the professional identity of clinical nurses, by optimizing the management organizational structure and pay attention to the perception of empowerment behavior to improve the comprehensive empowerment level, so as to enhance the professional identity of nurses.

Objective:To explore the incidence and degree of compassion fatigue in clinical nurses, and the effects of psychological empowerment on nurses' compassion fatigue level.Methods:A total of 1 005 clinical nurses were investigated with the general information, Chinese version of Professional Quality of Life Scale, Psychological Empowerment Scale. And the relationship between different degrees of compassion fatigue and psychological empowerment were analyzed by ordinal regression analysis.Results:The incidence of sympathetic fatigue was 93.0%,(935/1 005), mild was 53.8%(541/1 005), medium was 22.7%(228/1 005), severe was 16.5%(166/1 005). The score of Chinese version of Professional Quality of Life Scale three dimensions: compassion satisfaction, burnout, and secondary traumatic stress of clinical nurses were 34.15±5.53, 23.96±5.10, 23.73±5.92. The degree of compassion fatigue was negatively correlated with psychological empowerment score and score of each dimension( r values were 0.094-0.468, all P<0.05). The ordinal regression analysis indicated that job impact(odds ratio(OR) value was 1.095, 95% credible interval( CI) 0.094-0.236, P<0.01), self-efficacy( OR value was 0.920, 95% CI 0.250-0.054 , P<0.01) and job meaning( OR value was 0.820, 95% CI 0.431-0.240, P<0.01) were the independent risk factor of compassion fatigue level. Conclusions:The nurses mainly showed mild compassion fatigue, and main manifestation is secondary traumatic stress. The nurses who had more higher job impact scores were more likely to report higher levels of empathy fatigue, while nurses who had higher job meaning and self-efficacy scores were more likely to have low levels of empathy fatigue. Therefore, it is suggested that nursing managers should carry out timely intervention and management in accordance with the different level of compassion fatigue:improve nurses' perception of work meaning and self-efficacy, and avoid increasing workload while paying attention to the influence of work on perception level.

Objective To explore the multiple mediating role of positive psychological capital and adaptive emotion expression between individual social capital and humanistic care ability in nursing students. Methods From December 2018 to August 2019,the study selected 238 undergraduate nursing students of Grade 2015 to 2018 by cluster stratified sampling as subjects in a medical university. All of students were investigated with the Caring Ability Inventory, Individual Social Capital Questionnaire, Positive Psychological Capital Scale and Emotional Expression Questionnaire in college students of China. Structure equation model was used to analyze the correlations among the variables. Results Among 238 nursing students, the scores of humanistic care ability, individual social capital, positive psychological capital, inhibitory emotion expression, adaptive emotion expression and excessive emotion expression were (185.79±17.52), (20.26±2.38), (125.24±17.71), (17.23±3.86), (20.85±3.91) and (9.70±3.97) respectively. Individual social capital, positive psychological capital, adaptive emotion expression and humanistic care ability had positive correlations with each other (r=0.223-0.627,P<0.01). Multiple mediating effect model analysis showed that the positive psychological capital and adaptive emotion expression had multiple mediating roles between individual social capital and humanistic care ability in nursing students(P<0.05). The relative mediating effects of positive psychological capital, adaptive emotion expression and chain mediation were 83.37％, 11.64 ％ and 4.77％ respectively. Conclusions Nursing students have a low level of humanistic care ability with the adaptive emotion expression. Nursing educators can improve nursing students' individual social capital, enrich their positive psychological capital and strengthen their adaptive emotion expression so as to cultivate the humanistic care ability.

Objective:To explore the current status of career self-efficacy and positive psychological capital among undergraduate nursing students and to analyze the correlation between them.Methods:From May to June 2018, we selected 255 undergraduate nursing students in the first to the fourth grade of a medical university in Nanjing as the research objects by cluster sampling. All students were investigated with the General Information Scale, Career Self-efficacy Questionnaire for Nursing Students and Positive Psychological Capital Scale.Multiple linear regression was used to analyze the influencing factor.Results:255 questionnaires were distributed, and 238 valid questionnaires were recoverd.
