Effects of different types of interference on nurses' working memory: An ERP study.

AIM: To explore the effects of different types of interference on nurses' working memory, and the role of attention control. DESIGN: A repeated measures design. METHODS: A single-factor, four-level within-subjects design was adopted. Thirty-one nurses completed a delay-recognition task with four blocks in September 2020: Interrupting Stimulus (stimuli requiring attention), Distracting Stimulus (stimuli to-be-ignored), No Interference and Passively View. Behavioural responses of the participants and EEG data were recorded. MATLAB 21b and EEGLAB 21b were used for electroencephalogram data preprocessing and data extraction. RESULTS: Firstly, when nursing information system was used as task material, the accuracy rate and false alarm rate of primary tasks under interruption condition was statistically significantly different with that of distraction and no interference condition. There is a statistically significant difference in electroencephalogram measurement between correct and wrong response under interruption. Secondly, the role of attention control was different under interruption and distraction. There was a statistically significant positive correlation between the average amplitude distraction attention control index and task accuracy, and statistically significant negative correlation between the latency interruption attention control index and the accuracy of working memory task. CONCLUSIONS: There were different effects of interruptions and distractions on nurses' working memory and the role of attention control were also different. Measures can be designed according to these results to reduce the negative impact of interference on nurses, so as to improve work efficiency and reduce patient risk. IMPACT: This study has implications for clinical nursing during human-computer interaction. Resumption of the speed of the target information after an interruption affected task performance. Therefore, interventions should be designed to reduce the time needed for nurses to extract task information after an interruption, such as providing key clues in the information system interface. PATIENT OR PUBLIC CONTRIBUTION: Registered nurses participated in the study as subjects.

Nurses' turnover intention, hope and career identity: the mediating role of job satisfaction.

BACKGROUND: A high turnover rate has become a critical issue in the field of nursing and how to tackle the problem of nursing turnover has received increased attention worldwide. Hope, career identity, job satisfaction may be useful for reducing turnover. The aim of this study is to explore the relationships among career identity, hope, job satisfaction, and the turnover intention of nurses, and to test the mediating role of job satisfaction on the associations of hope and career identity with turnover intention. METHODS: A descriptive cross-sectional design was used. A total of 500 nurses were recruited from five comprehensive tertiary hospitals using convenience sampling. The questionnaire included items about sociodemographic information as well as the Adult Dispositional Hope Scale, Nursing Career Identity Scale, Job Satisfaction Index Scale, and Nurse Turnover Intention Scale. Pearson's correlation, multiple linear regression, and structural equation modeling were used to analyze the data. We describe the study in accordance with the STROBE statement. RESULTS: Hope (r = - 0.227, p < 0.001) and career identity (r = - 0.342, p < 0.001) were negatively correlated with turnover intention. Job satisfaction played a completely mediating role on the associations of hope and career identity with turnover intention (ß1 = - 0.09, ß2 = - 0.33). CONCLUSIONS: Job satisfaction mediated the associations of career identity and hope with turnover intention. Thus, effective measures can be taken to enhance nurses' hope and career identity in order to improve their job satisfaction and thereby reduce their turnover intention. Providing nurses with more support, helping them find a spiritual foundation, and holding mindful activities that stimulate positive emotions are helpful. In addition, colleges should pay more attention to instilling nursing students with career identity and nursing values.

Development and testing of the knowledge-attitudes-practices questionnaire for nurses on the perioperative pulmonary rehabilitation of patients with lung cancer.

Objective: This study aims to develop and validate a suitable scale for assessing the level of nurses' knowledge and practice of perioperative pulmonary rehabilitation. Methods: We divided the study into two phases: scale development and validation. In Phase 1, the initial items were generated through a literature review. In Phase 2, a cross-sectional survey was conducted involving 603 thoracic nurses to evaluate the scale's validity, reliability, and difficulty and differentiation of items. Item and exploratory factor analyses were performed for item reduction. Thereafter, their validity, reliability, difficulty, and differentiation of items were assessed using Cronbach's α coefficient, retest reliability, content validity, and item response theory (IRT). Results: The final questionnaire comprised 34 items, and exploratory factor analysis revealed 3 common dimensions with internal consistency coefficients of 0.950, 0.959, and 0.965. The overall internal consistency of the scale was 0.966, with a split-half reliability of 0.779 and a retest reliability Pearson's correlation coefficient of 0.936. The content validity of the scale was excellent (item-level content validity index = 0.875-1.000, scale-level content validity index = 0.978). The difficulty and differentiation of item response theory were all verified to a certain extent (average value = 2.391; threshold ß values = -1.393-0.820). Conclusions: The knowledge-attitudes-practices questionnaire for nurses can be used as a tool to evaluate knowledge, attitudes, and practices among nurses regarding perioperative pulmonary rehabilitation for patients with lung cancer.

Research-training needs of clinical nurses: A nationwide study among tertiary hospitals in China.

OBJECTIVE: This study aimed to evaluate Chinese tertiary hospital nurses' research output, research ability, and their related training needs regarding scientific research methodology and analyze the relations among them. METHODS: A nationwide survey was conducted in China on a large sample of tertiary hospital nurses (n = 27,335) recruited from 22 provinces, autonomous regions, and municipalities. A validated, self-designed questionnaire, consisted of a common questionnaire, the Science Research Skills Self-Rating Questionnaire (SRSQ) and the Scientific Research Training Needs Questionnaire (SRTNQ) were used to assess nurses' research output, self-rated research skills and research-training needs. RESULTS: The nurses' scientific research participation rates (with 4.13%, 7.85%, 5.35%, and 2.04% in research projects, research attendance, papers published, and patent, respectively) and their self-rated research skills 25.00 (12.50, 37.50) were very low. However, the research training needs were relatively high 53.12(37.50, 75.00). Significant differences in research participation rates (research projects, research attendance, papers published, and patent), scientific research skills, and research-training needs were determined by age, highest education level, nursing experience, employment, technical title, administrative post, and clinical tutoring experience (P < 0.05). Female and male nurses had different research participation rates (only research projects and studies published) and scientific research skills (P < 0.05). Positive correlations were observed among research output, scientific research skills, and research-training needs (P < 0.01). CONCLUSIONS: Nurses' scientific research participation and self-rated research ability were below the optimal despite that they had relatively high research-training needs. Nurses should be provided further research training with tailored content to their characteristics and capacity.
