Objective To explore the effects of PDCA nursing model on improving negative emotion and mood state of patients with depression. Methods A total of 70 patients with depression in our hospital between January 2013 and June 2014 were randomly divided into control group ( routine depression nursing group) and observation group ( PDCA nursing intervention group) with 35 cases in each group. The emotion and mood state of two groups before and after intervention were evaluated with Zung′s self-rating depression scale ( SDS) , positive and negative affect schedule ( PANAS) and profile of mood state ( POMS) . Results After the intervention, the scores of SDS, PANAS and POMS in the observation group were all improved more than those in the control group at 1w, 2w and 4w. The differences between two groups were statistically significant ( P<0. 05). Conclusions PDCA nursing model can improve the negative emotion and mood state of patients with depression and help recovery of disease.

Objective:To understand the status quo of autonomous learning ability of nurses in ClassⅢ Grade A psychiatric hospitals and analyze its influencing factors, so as to provide a basis for further improvement of nurse specialist education.Methods:Using the convenient sampling method, a questionnaire survey was conducted among 910 nurses in 5 ClassⅢ Grade A psychiatric hospitals in Zhejiang province from July to October 2019. The survey methods included General Information Questionnaire and Self-Learning Ability of Nursing Staff Evaluation Scale. Multiple linear regression analysis was carried out on the influencing factors of autonomous learning ability of nurses. A total of 910 questionnaires were issued and 904 valid questionnaires were recovered.Results:The total score of Self-Learning Ability of Nursing Staff Evaluation Scale of 904 nurses was (118.43±19.14) , the score of self-motivation belief dimension was (49.49±8.32) and score of the self-evaluation dimension was (14.05±2.39) . There were statistically significant differences in scores of autonomous learning ability of nurses among different genders, working departments, initial and final education background, employment method and current post ( P<0.05) . The results of multiple linear regression analysis showed that gender, initial education, current post and work department were the main factors affecting the autonomous learning ability of nurses, which jointly explained 40.1% of the total variation of the autonomous learning ability of nurses in psychiatric hospitals ( R2=0.401, F=15.685, P<0.001) . Conclusions:The self-learning ability of nurses in psychiatric hospitals is at a general level. Nursing managers should pay attention to the group of nurses with low self-learning ability, and carry out multi-level, multi-form and multi-channel on-the-job training methods for nurses with different educational backgrounds and posts to promote the improvement of self-learning ability and overall quality of nurses.
