你好，“局限性”的写作！
重复一下小班长的观点：太爱《The Journal of Nursing Management》这个杂志啦！初尝试护理管理主题的老师可以去试一下这个杂志~
首先，大家一定见过很多中文护理核心上关于相关性研究的文献，比如，
[1]侯向华,张学长,孙丹丹,张情,张立文,李伟.我国男护士心理契约与工作投入的相关性研究[J].中国护理管理,2020,20(09):1390-1395.
[2]景丽伟,江佳隆,邢凤梅,周松飞,张超.中高龄居家不出老年人领悟社会支持与生活质量的相关性研究[J].中国护理管理,2020,20(08):1192-1196.
[3]蒋婷婷,单岩,杜理平,李艳艳,周越,蔡利,蒋鑫鑫,高雅靖.老年血液透析患者认知衰弱现状及其与跌倒恐惧的相关性研究[J].中国护理管理,2020,20(07):1005-1009.
基本的思路都是：①使用两个量表去做横断面调查；②汇报两个变量的得分现状，并分析其相关性。
今天给大家分享的这篇源自《The Journal of Nursing Management》上的文献，思路基本也是与上述一致。
文献：Moazez, M, Miri, S, Foroughameri, G, Farokhzadian, J. Nurses’ perceptions of systems thinking and safe nursing care: A cross‐sectional study. J Nurs Manag. 2020; 28: 822– 830. https://doi.org/10.1111/jonm.13000
护士对系统思维与安全护理的认知：一项横断面研究
小班长分享这篇文献的推荐的理由是：其“局限性”部分的写作很漂亮。我先给大家附上（提示：基本横断面研究的局限性写作逃不开这3点内容）：
LIMITATIONS 局限性
The present study had several limitations. First, use of a self-reporting method for data collection could result in exaggerative scores and personal bias. Second, the cross-sectional method applied in this study could not evaluate the cause and effect relationship between safe nursing care and systems thinking. Third, this study was carried out in one university; therefore, the results are not generalizable to other universities and settings. As a result, we recommend future researchers to conduct experimental and cohort studies by controlling the confounding variables in various clinical settings.
存在3个方面的局限性。①使用自我报告的方法收集数据可能会导致夸大的分数（偏高）和个人偏见。②本研究采用的横断面方法不能确定安全护理与系统思维两个之间的因果关系。③本研究是在其中一所大学进行的，因此，研究结果可能并不适用于其他大学和单位环境。因此，我们建议未来的研究人员通过控制各种临床环境中的混杂变量来进行试验和队列研究。

Abstract摘要
Aim To assess nurses’ perceptions of systems thinking, safe nursing care and the correlation between them.
研究目的：评估护士对系统思维能力和安全护理的认知，及其相关性研究。
Background Systems thinking and safe nursing care are the key elements of quality improvement approaches, such as accreditation and patient safety programmes. However, these two variables have not been well studied in different health care settings.
研究背景：系统思维和安全护理是质量改进方法的关键要素，如护理认证体系和患者安全计划。然而，这两个变量在不同的卫生保健环境中还没有得到很好的研究。
Methods In this cross‐sectional study, 300 nurses were selected using the stratified random sampling method. The data were collected using a demographic data form, systems thinking scale and assessment of safe nursing care questionnaire.
研究方法：采用横断面研究设计，应用分层随机抽样方法，选取300名护士进行调查。采用一般人口学资料调查表、系统思维量表和安全护理评估问卷进行数据收集。
其中，①系统思维量表systems thinking scale：主要是用来评估护士识别、理解和整合事件发展，因果，多因素，反馈及相关因素等的能力。（简单来说，就是评估护士在安全护理中的系统思维能力）②安全护理评估量表assessment of safe nursing care (ASNC)：该调查表评估了护士在防止患者受到伤害和最大程度地及早发现错误方面的实践。
Results The scores of nurses’ perceptions of systems thinking (63.25 ± 9.20) and safe nursing care (4.13 ± 0.60) were above average. A positive correlation was found between systems thinking and safe nursing care (r=0.66,p<0.001), and its dimensions: nursing skills (r=0.61,p<0.001), psychological needs (r=0.56,p<0.001), physical needs (r=0.51,p<0.001) and teamwork (r=0.56, p<0.001).
研究结果：
①现状：护士系统思维感知得分为(63.25±9.20)、安全护理感知得分为(4.13±0.60)均高于平均水平。
②相关性：系统思维总分与安全护理总分呈正相关(r = 0.66, p＜0.001)，系统思维与安全护理各维度的相关性：护理技能(r=0.61, p＜0.001)，心理需求(r=0.56, p＜0.001)，生理需要(r=0.51, p＜0.001)和团队合作(r=0.56, p＜0.001）。
Conclusion Regarding the correlation between systems thinking and safe nursing care, nurses and other medical professionals, especially novices, are recommended to strengthen their systems thinking skills to improve the safe nursing care.
研究结论：关于系统思维与安全护理的相关性结果显示，建议护士及其他医学专业人员，特别是初学者，加强系统思维技能，以提高安全护理水平。
Implications for Nursing Management
Nurse managers should deal with organisational condition and factors affecting some poor aspects of systems thinking and safe nursing care. They must lead, support and allocate resources to the foundations of systems thinking to achieve safe nursing care.
对护理管理的启示：护士管理者应处理组织现状和影响系统思维和安全护理的一些不良方面的因素。他们必须领导、支持和分配资源以构建系统思维能力，进而实现安全护理。
