Introduction
With the rapid development of high and new medical technology and the current social transformation period, there have been some new changes in the nurse-patient relationship [
1]. The work of nurses is no longer a simple operation of basic skills such as injection and medicine dispensing, but we need to constantly explore the new changes in the new era of nursing ethics, so as to guide the cultivation of the professional ethics of nurses, nursing professional elements and ethical requirements internalized into nurse behavior habits [
2‐
4]. Therefore, it is particularly important to pay attention to the cultivation of ethical sensitivity. Ethical sensitivity is an important part of nursing practice. No matter the in-role behavior required by the position or the spontaneous out-of-role behavior, they are all in the ethical context of communicating and dealing with patients [
5]. The ability to identify ethical problems is a lifelong learning process for nursing staff. Ethical sensitivity has been proved to be related to understanding ethical dilemma and dealing with ethical conflict, cultivating clinical ethical decision-making ability, forming ethical professional accomplishment and practicing ethical behavior norms [
6‐
8].
Ethical sensitivity is a positive attribute in theory, and awareness of the existence of ethical issues is a prerequisite for decision-making and taking actions [
9]. Improving the ethical sensitivity of nursing students can strengthen the ethical cognition of nursing students and enhance the practice ability of clinical decision-making [
10]. In the face of the new pattern of health development, nursing students must keep up with the trend and constantly improve their own ethical sensitivity. High ethical sensitivity is conducive to improving the ability of combining nursing students’ professional level with nursing ethics and moral quality. Lack of ethical sensitivity will lead to the loss of moral responsibility and negative health consequences.
Ethical sensitivity is an evolving concept. Rest [
11] defined ethical sensitivity as the ability to make ethical decisions without obvious ethical conflicts and to evaluate the reactions and feelings of others and to recognize their relative importance to the patient and the potential course of action to take. Lützén and colleagues [
12] pointed out that ethical sensitivity is the ability to show contextual and intuitive understanding of patients’ vulnerable situations, to recognize ethical conflicts and to have insight into the ethical consequences of their decisions.
Previous studies have shown that the Moral Sensitivity Questionnaire (MSQ) developed by Lützén and colleagues [
12] was often used to measure ethical sensitivity among nurses in Japan [
13] and Korea [
14]. However, China lacks such instruments. Although some studies have also used the Moral Sensitivity Questionnaire-Revised Version into Chinese (MSQ-R-CV) translated by Huang et al. in 2015 [
15], which is mainly used by nurses or professionals. Currently, there is a lack of effective tools to assess the level of ethical sensitivity of nursing students. This must be urgently addressed so that the education and training sector can be kept informed.
Taeko Muramatsu and colleagues [
16] defined the ethical sensitivity of nursing students as the ability to identify ethical issues in nursing practice and developed a validated instrument called the Ethical Sensitivity Questionnaire for Nursing Students (ESQ-NS). Altogether, 13 items for nursing students were identified and classified into there domains: respect for individuals, distributive justice, and maintaining patients’ confidentiality. Studies [
17‐
19] have shown that ethical sensitivity can be improved through training and education. The measuring instrument of ethical sensitivity can help nursing students understand their sensitivity level more clearly, which is conducive to making up for their shortcomings. It can promote nursing students in the future nursing practice can be sensitive to find the patient’s problems, understand the patient’s situation, as far as possible to avoid the occurrence of nurse-patient conflict. In a complex and challenging health care environment, this is critical for the future development of nursing students. The purpose of this study was to translate ESQ-NS into Chinese and to describe the reliability and validity of the Chinese version of ESQ-NS among nursing students.
Discussion
The Chinese version of ESQ-NS scale strictly followed the procedures of translation, back-translation, cultural adjustment and pre-survey [
20]. At each stage, the experts discussed and modified fully, and according to the Chinese guidelines and common expressions, the Chinese version of ESQ-NS was obtained.
The results of this study showed that the items of the Chinese version of ESQ-NS were consistent with those of the original scale, and no items were deleted. However, the factor structure of the Chinese version is slightly different from that of the original one. The original ESQ-NS had three dimensions: respect for individuals (Item 1-8), distributive justice (Item 9-11) and maintaining patients’ confidentiality (Item 12-13), with a total of 13 items. In this study, exploratory factor analysis showed that the first factor had 4 items, involving the original scale 1, 2, 3 and 5, named “respect for individuals”. Factor 2 had 4 items in total, involving the original scale 4, 6, 7 and 8. Based on expert opinions, literature review and the underlying characteristics of the items, we renamed it “reasonable care”. The dimensions of factor 3 and factor 4 were exactly the same as those of the original scale, indicating that they were easier to apply cross-culturally. An EFA determined 13 items categorized under four factors (respect for individuals, reasonable care, distributive justice, maintaining patients’ confidentiality), which explained 62.479% of the total variance. Each item had a factor loading of 0.60 or higher, which was considered ideal [
34].
The researchers interpreted and labeled the emerging factor according to the core concepts of the human care theory by WATSON J [
35]. The second factor (“reasonable care”) explains 16.683% of the total variance and should be considered as the main aspect for the existence of a valid assessment of ESQ-NS level. Watson’s theory points out that care is the essence of nursing, which provides theoretical core knowledge for patient care and provides a new dimension for revealing the core essence of nursing. Literature [
36,
37] have revealed that in the analysis and application of human care theory, the dynamic change of human care needs in different stages plays an important role in clinical nursing practice, nursing education, nursing management and other fields. In fact, studies [
38,
39] have shown that due to the lack of safe nursing knowledge and medication methods. Many patients have been admitted to professional institutions for treatment or formal care, which also suggests that nursing staff should strengthen the study of basic principles and ethical requirements of care. Nursing students are the reserve force of medical service application-oriented talents. Their willingness to care directly affects the quality of future care system professionals [
40]. Therefore, we use “reasonable care” as an independent factor in evaluating ethical sensitivity tool, rather than being included among other factors.
In our study, in addition to the three basic aspects of the original version, our scale includes “reasonable care” (factor 2), which makes the domain classification of the Chinese scale more specific. Considering that the incidence of nurse-patient relationship, nurse-patient disputes, nurse-patient conflicts and other cases is increasing year by year, nursing students believe that the focus of professional nursing is to care patients, hope to take better care of patients through their own ability, and have a stronger sense of responsibility for taking care of patients [
41]. This may be influenced by different medical environment, cultural background and subject education at home and abroad. Different regions have different educational modes for nursing students, so they have different understandings of problems. Further research is needed to see if the findings can be applied to other cultures.
According to the expert evaluation method, the content validity range of I-CVI of each item level was 0.857~1.000 ( I-CVI≥0.78) [
22]. The value of I-CVI ranges from 0 to 1. A larger value indicates that the item is more representative and more suitable for the items in the scale. The S-CVI/Ave of ESQ-NS reached 0.956 (>0.90), indicating that the scale has good content validity [
42]. The analysis shows that the Bartlett spherical test<0.01, KMO>0.6, with a value of 0.857 indicating a moderate-to-high level of adequacy of the correlation matrix, which shows that the data are suitable for factor analysis. Four common factors were obtained through CFA analysis, each index has good adaptability and within a reasonable range (CMIN/DF<3, CFI, IFI, GFI, AGFI,TLI>0.90,PGFI>0.50,RMR<0.05, RMSEA<0.08). The results prove that factor loading and interpretation variance are strong, which are consistent with EFA results, and have a good four-factor structure and model fitting index. The findings showed that the Chinese version of ESQ-NS could reflect the ethical level of nursing students and the function of nursing students in four dimensions. A significant positive correlation was found between ESQ-NS and MSQ-R-CV (
r=0.488,
P<0.001). The results show that the concurrent validity was well.
In the ESQ-NS, the internal consistency of the Chinese version of ESQ-NS and its 4 dimensions, as measured by Cronbach alpha coefficient, were all greater than 0.7. The internal consistency were consistent with those of the original study [
16]. Corrected item-total correlation are greater than 0.3. Test-retest reliability of the whole scale was 0.814. All result show that the scale is stable and all indexes are within a reasonable range, so it can be considered as a reliable assessment tool to be applied to Chinese nursing students.
