Most studies that have developed instruments for measuring ethical conflict base their measures on the variables ‘frequency’ and ‘degree of conflict’. In our view, however, these variables are insufficient for explaining the root of ethical conflicts. Consequently, the present study formulates a conceptual model that also includes the variable ‘exposure to conflict’, as well as considering six ‘types of ethical conflict’. An instrument was then designed to measure the ethical conflicts experienced by nurses who work with critical care patients. Homework: Ethical Issues in Nursing

The paper describes the development process and validation of this instrument, the Ethical Conflict in Nursing Questionnaire Critical Care Version (ECNQ-CCV). Methods: The sample comprised 205 nursing professionals from the critical care units of two hospitals in Barcelona (Spain). The ECNQ-CCV presents 19 nursing scenarios with the potential to produce ethical conflict in the critical care setting. Exposure to ethical conflict was assessed by means of the Index of Exposure to Ethical Conflict (IEEC), a specific index developed to provide a reference value for each respondent by combining the intensity and frequency of occurrence of each scenario featured in the ECNQ-CCV. Following content validity, construct validity was assessed by means of Exploratory Factor Analysis (EFA), while Cronbach’s alpha was used to evaluate the instrument’s reliability. All analyses were performed using the statistical software PASW v19. Results: Cronbach’s alpha for the ECNQ-CCV as a whole was 0.882, which is higher than the values reported for certain other related instruments. The EFA suggested a unidimensional structure, with one component accounting for 33.41% of the explained variance. Conclusions: The ECNQ-CCV is shown to a valid and reliable instrument for use in critical care units. Its structure is such that the four variables on which our model of ethical conflict is based may be studied separately or in combination. Homework: Ethical Issues in Nursing

 The critical care nurses in this sample present moderate levels of exposure to ethical conflict. This study represents the first evaluation of the ECNQ-CCV. Background Ethical conflicts have been analysed for several years in various clinical contexts. Research suggests that such conflicts are on the rise in the nursing field, due both to the increasing complexity of care and the scientific and technological advances which have been made in recent decades. In this regard, critical care units are a setting that * Correspondence: annafalco@ub.edu 1 Department of Fundamental Care and Medical-Surgical Nursing, Campus of Health Science of Bellvitge, Nursing School, University of Barcelona, Central Pavilion, 3r floor, 08907 L’Hospitalet de Llobregat, Barcelona, Spain Full list of author information is available at the end of the article is especially prone to conflict [1-14]. Various authors have suggested that the ethical conflicts experienced by critical care nurses stem from three main sources: the relationships with patients and their families, the provision of certain treatments and/or the characteristics of the setting in which the clinical team works. As regards the first of these, the decision-making process comes up against issues such as the difficulty of ensuring informed consent, a failure to respect confidentiality or the lack of protection of the patient’s interests [5,9,15-21].

Similarly, Glasberg’s construct stress of conscience [34,35] was described as the product of these two variables. In our view, however, the sole use of these two variables (i.e. frequency and degree of ethical conflict) to analyse ethical conflicts is insufficient when it comes to explaining the root of the conflict or the difficulty of making the correct decision from a moral perspective. Indeed, it is noteworthy that research has yet to consider as a whole the different types of ethical conflict described by Jameton [27] and Wilkinson [15]. Neither have we found any studies that take into account the absence of moral conflict as a positive perspective inside a model. Consequently, we have formulated a model for the analysis of ethical conflict (Figure 1) that is based on the following premises: a) in order to study ethical conflict it is necessary to consider four variables: frequency of conflict, degree of conflict, exposure to conflict and type of conflict; b) the variable ‘exposure to conflict’ is the product of the variables ‘frequency’ and ‘degree of conflict’; c) the variable ‘type of conflict’ should take into account the continuum between the presence and absence of ethical conflict. The presence of ethical conflict would correspond to the four categories or types of conflict described by Jameton [26,27] and Wilkinson [15]: moral uncertainty, moral dilemma, moral distress and moral outrage. In order to -Index of exposure to ethical conflict + ( IEEC = Fx D) Presence of ethical conflict Moral outrage Absence of ethical conflict aggressive, when pain management seems to be deficient or when it becomes necessary to limit the use of life support procedures [1,5,15-17,22-24]. Finally, in relation to workplace dynamics, conflict may arise if nurses are not fully involved in the decision-making process or if they feel the work environment makes it difficult to consider questions of a bioethical nature [4,12,15,17,19-25]. Such situations have the potential to produce different ethical conflicts in the individual, and these conflicts will reflect the root of the difficulty in making the right decision. In this context, Andrew Jameton [26] coined the term moral distress and identified three types of ethical conflict which nurses may experience in the clinical setting: moral uncertainty, moral dilemma and moral distress. In a situation of moral uncertainty the professional is either unsure whether there is an ethical problem or not, or recognizes that there is such a problem but is unclear about the ethical principles involved. Moral dilemmas arise when the professional must choose between two or more morally correct principles, each of which would lead to a distinct course of action. Homework: Ethical Issues in Nursing

Finally, moral distress is felt when the professional recognizes the ethical principles involved and knows the right thing to do but is constrained by something or somebody from acting accordingly. Some years after Jameton’s work was first published Judith Wilkinson [15] referred to what she called moral outrage, a type of ethical conflict in which the professional experiences a sense of impotence in the face of an immoral action performed by others. In 1993 Jameton included this type of conflict in his own classification [27]. Although a considerable body of research has considered the types of ethical conflict experienced by nurses, only a few studies have developed instruments for measuring these conflicts. The principal instruments to date have focused on the evaluation of moral distress and stress of conscience. The Moral Distress Scale, developed by Corley [1], was the first instrument of its kind and was subsequently adapted by various authors [6,10,11,20,21,28-30]. Kälvemark-Sporrong’s Moral Distress Questionnaire [31] was designed to explore the relationship between moral distress, ethical competence and the ability to tolerate stress among health professionals. This instrument was also adapted in subsequent research [25,31-33]. Finally, the Stress of Conscience Questionnaire was developed by Glasberg [34] to examine the relationship between stress of conscience and burnout, a relationship that was later confirmed by other studies [35-37]. Most of the research which has set out to analyse ethical conflicts has focused predominantly on two variables: the frequency with which situations of conflict arise and the degree of ethical conflict perceived by the individual concerned. As regards the relationship between these two variables, Corley [23] and Pauly [29] report there to be a positive relationship (p < 0.01) in the Page 2 of 8 Moral distress Moral dilemma Moral uncertainty Moral wellbeing Moral indifference Figure 1 Model for the analysis of ethical conflict. Falcó-Pegueroles et al. BMC Medical Ethics 2013, 14:22 http://www.biomedcentral.com/1472-6939/14/22 capture the absence of ethical conflict our model defines a further two categories: moral wellbeing and moral indifference [24]. Moral wellbeing refers to a positive state in which moral thought and action are clearly coherent with one another. Moral indifference describes the stance of an individual who neither shows interest in nor takes a position on a matter of ethical concern. Based on this model of ethical conflict we then developed an instrument for evaluating its components. The focus of the present study is on critical care nursing, and the paper describes the development and validation of the instrument designed to measure ethical conflicts in this setting, the Ethical Conflict in Nursing Questionnaire-Critical Care Version (ECNQ-CCV). Homework: Ethical Issues in Nursing

Methods Item generation The initial pool of items was created through an extensive review of the literature on sources of ethical conflict in nursing and in the critical care setting. During the search particular emphasis was placed on identifying and selecting care scenarios that generated an ethical problem, a moral dilemma or moral distress. A total of 31 situations involving an ethical conflict were identified. Those situations which produced conflict of another kind, for example, staff-related or financial, were excluded. The 31 scenarios were then analysed and adapted to the specific context of critical care units, grouping them into 11 areas with the potential to produce an ethical conflict. These areas were as follows: informed consent, confidentiality, withholding and withdrawing treatments, the patient’s interests, characteristics of an ethical environment, procedures and treatments, interprofessional relationships, moral agency and professional values, privacy, research tasks and resource management. In order to reduce the number of scenarios we then grouped together any that were related to one another, the result being a total of 19 situations, each of which was represented by one item on the questionnaire. The 19 scenarios were then analysed in accordance with the Code of Ethics of the International Council of Nurses [38] in order to identify which articles of the Code might be implicated in each case. The questionnaire: content validity and pilot study The instrument, which we called the Ethical Conflict in Nursing Questionnaire-Critical Care Version (ECNQCCV), was developed in Spanish and initially comprised the 19 care scenarios with the potential to produce an ethical conflict in nurses working in critical care units. In order to test the content validity of this initial version of the ECNQ-CCV each of its items was rated by two committees of experts. One committee (the Ethics Committee) comprised four experts in the field of ethics and nursing ethics, while the other was formed by Page 3 of 8 four experts in critical care nursing (the Critical Care Committee). Each member of both committees evaluated the ECNQ-CCV according to the following two parameters: ‘Relevance of the item for exploring ethical conflict’ (RI) and ‘Degree of ethical conflict’ (DEC). The members of the Ethics Committee also evaluated the items according to the degree of agreement in the ‘Definition of ethical concepts’ (DEFEC), whereas the Critical Care Committee was asked to consider, as a third parameter, the ‘Frequency of occurrence of each scenario’ (FO). Ratings of the four parameters (RI, DEC, DEFEC and FO) were made using a Likert scale with five or six response options, and there was also a section in which the experts could make any comments or suggestions they felt were necessary. Content validity was then assessed by means of two procedures. Homework: Ethical Issues in Nursing

The data corresponding to the parameters RI, DEC and FO were analysed according to the consensus method described by Fehring [39]. This method classifies the degree of agreement into four categories: 0 to 0.24 = no consensus, 0.25 to 0.49 = little consensus, 0.50 to 0.74 = considerable consensus, and 0.75 or higher = strong consensus. The results showed that three items (Item 2, Item 13 and Item 16) yielded values below 0.50 with respect to RI and DEC, thereby suggesting that they should be eliminated. However, one of these items (Item 2) produced a value above 0.50 on FO and it was therefore retained. The other two items were replaced with two new items suggested by some of the experts. One item referred to the effect of a lack of resources on care, while the other concerned institutional interests coming before those of the patient. The parameter DEFEC was analysed by using Kendall’s coefficient of concordance to determine the degree of agreement between experts. The degree of agreement obtained was sufficient: W = 0.519 for the four types of ethical conflict and W = 0.750 for the degree of agreement between the categories moral dilemma and moral distress. The questionnaire therefore comprised 19 items, each of which described a critical care scenario in which nurses might experience an ethical conflict. For each item, three questions were formulated, corresponding to the parameters ‘frequency of occurrence of the ethical conflict’ , ‘degree of perceived ethical conflict’ and ‘type of ethical conflict experienced’ (Additional file 1). The variable ‘frequency of occurrence’ was rated according to six categories: never, almost never, at least once a year, at least once every six months, at least once a month, and at least once a week. Homework: Ethical Issues in Nursing

‘Degree of conflict’ was rated across five categories: no problem at all, mildly problematic, fairly problematic, considerably problematic, and highly problematic. Finally, six categories were used to rate the ‘type of ethical conflict experienced’. Four of these were Falcó-Pegueroles et al. BMC Medical Ethics 2013, 14:22 http://www.biomedcentral.com/1472-6939/14/22 the four types of ethical conflict defined by Jameton [26,27] and Wilkinson [15]: moral uncertainty, moral dilemma, moral distress and moral outrage. The remaining two categories referred to moral states in which no ethical conflict was present: moral wellbeing and moral indifference [24]. The instrument in this form was then piloted with a sample of 20 nurses from the critical care unit of a hospital in the city of Barcelona, the characteristics of which were similar to those of the two hospitals chosen for the main study. In this pilot study, 72% of the nurses surveyed considered that the ECNQ-CCV had sufficient scope and 28% regarded it as acceptable. 78% affirmed it was sufficiently clear and the remaining 22% declared it was clear. These results meant that no substantial changes needed to be made to the design or content of the questionnaire. Index of Exposure to Ethical Conflict (IEEC) As mentioned earlier the model of ethical conflict on which this study is based includes the variable ‘exposure to conflict’. This variable results from the relationship between the frequency with which an individual encounters an ethical conflict and the degree of conflict that such situations produce in that individual. This relationship is best regarded as a continuum. At one extreme there would be no ethical conflict: the individual has either never been in a situation of potential conflict, or has been but no conflict was produced (zero frequency – zero intensity). The other end of the continuum would be anchored by maximum or strong ethical conflict: the individual frequently encounters situations of ethical conflict and the degree of conflict produced is very intense (high frequency – high intensity). Homework: Ethical Issues in Nursing

Between these two extremes would lie intermediate combinations: low frequency – high intensity; high intensity – low frequency. In order to estimate ‘exposure to ethical conflict’ we developed a specific index, the Index of Exposure to Ethical Conflict (IEEC), which yields a reference value for each subject. The IEEC is calculated by means of the following equation: IEEC ¼ 19 X ðF i  D i Þ i¼1 where (Fi) is the frequency of occurrence of each situation (Itemi) and (Di) is the degree of intensity corresponding to that situation. The value of the IEEC therefore provides an estimate of the frequency and intensity with which a given subject experiences each of the 19 scenarios listed within the ECNQCCV, the sum of its products reflecting the interaction between the ratings given for frequency and intensity. Thus, the IEEC enables respondents to be Page 4 of 8 evaluated and ordered according to the degree of ethical conflict they experience. The possible score for each item ranges from 0 to 25: 0 is the product of the categories Zero Frequency – Zero Intensity (‘0 – Never’ × ‘0 – No problem at all’) and 25 is the product of the categories High Frequency – High Intensity (‘5 – At least once a week’ × ‘5 – Highly problematic’). The range of the IEEC is therefore 0 to 475, the upper limit being the product of 19 × 25 (19 = the number of scenarios included in the ECNQ-CCV with the potential to produce ethical conflict × 25 = maximum value of the IEEC for each situation). Participants and setting Participants were critical care nurses with at least one year of professional experience who were recruited through two tertiary level hospitals, one in Barcelona (Spain) and the other in the metropolitan area of the same city.

Both centres were linked to the University of Barcelona. The sample comprised 205 nurses who worked in the critical care units of these two hospitals. As the total number of critical care nurses at these hospitals was 292, the sample accounted for 70% of the population. Socio-demographic, academic, professional and institutional information regarding the sample was collected by means of a data sheet comprising 20 questions. This data sheet was attached to the ECNQ-CCV. Administration of both the ECNQ-CCV and the complementary data sheet took place during October and November 2009. Homework: Ethical Issues in Nursing

Statistical analysis All data were analysed using PASW v19 for Windows. The tests of normality and the analyses of the reliability and construct validity of the Ethical Conflict Nursing Questionnaire were based on the IEEC. Internal consistency was calculated using Cronbach’s α coefficient. Construct validity was assessed by means of Exploratory Factor Analysis (EFA), examining the scree plot in order to interpret dimensionality. Measures of central tendency were studied for the IEEC, and the Kolmogorov-Smirnov and Shapiro Wilks tests were applied in order to assess the goodness of fit of the distributions. Variances were also analyzed with ANOVA test or the corresponding non- … Homework: Ethical Issues in Nursing
