This quasi-experimental study utilized a pre-test-post-test design and was conducted among undergraduate nursing students in the 7th and 8th semesters at the Islamic Azad University in Golestan province during the first semester of the 2023 - 2024 academic year. The study protocol was approved with the ethics code
IR.IAU.TON.REC.1402.098 by the Islamic Azad University, Aliabadkatul Branch, and was registered under the clinical trial code
IRCT20240219061050N1 in the Iranian Registry of Clinical Trials.
Based on a similar study by Fard et al. (
20), and considering a type I error of 0.01 and a test power of 90%, the required sample size for this study was calculated as 23 participants per group using the sample size formula for interventional studies. To account for a potential 10% dropout rate, the final number of n = participants in each group was set at 25, resulting in a total sample size of 75 participants.
The participants in this study were selected through cluster sampling. To do so, three faculties out of five nursing faculties in Golestan province were selected by drawing lots. For randomization, sealed envelopes containing letters representing three groups (X: The situation simulation group, Y: The reflection group, and O: The control group) were used to assign group membership at three university branches: The situation simulation group (Aliabadkatol Branch), the reflection group (Gonbadkavous Branch), and the control group (Azadshahr Branch). The number of students in the 7th and 8th semesters at the Aliabadkatol, Gonbadkavous, and Azadshahr branches were 50, 45, and 48, respectively. A total of 75 students were selected through convenience sampling and randomly assigned to the three groups, each consisting of 25 students.
The inclusion criteria were being a nursing student in the 7th or 8th semester, willingness to participate in the study, not having used modern educational methods, and not having failed the nursing ethics course. The exclusion criteria included being absent for more than one session, unwillingness to continue attending the training sessions, being an exchange student, or being transferred to another university.
Before conducting the interventions, a briefing session was held separately for students in each group at each faculty. First, the students were informed about the objectives of the study, the research procedure, the confidentiality of their data, and the fact that their participation or non-participation would not affect their academic evaluations. The participants were also given written and verbal assurances that they could withdraw from the study at any stage. Written informed consent was obtained from all participants before the interventions began. Additionally, the participants were assured that their involvement in the study would not incur any financial costs and that the researcher would be available to answer any questions or concerns they had during the intervention, with care and patience. Following this, a demographic information form (which assessed the participants' age, gender, nursing ethics course grade, and overall GPA) and Costa and McCrae’s Work Conscientiousness Scale were completed by the participants in all three groups as a pretest.
The Work Conscientiousness Scale consists of 16 items from Costa and McCrae’s (1992) NEO Personality Inventory. A total of 8 items (items 1 to 8) are related to the dependability subscale (e.g., "I am a very competent and efficient person"), while the other 8 items (items 9 to 16) measure the achievement orientation subscale (e.g., "I work hard to achieve my goals"). The purpose of this questionnaire is to assess work conscientiousness from different dimensions. The items are scored on a five-point Likert Scale: Strongly agree (4), agree (3), undecided (2), disagree (1), and strongly disagree (0). The overall conscientiousness score is calculated by summing the scores of all items. The dependability subscale score is calculated by summing the scores for items 1 to 8, and the achievement subscale score is calculated by summing the scores for items 9 to 16. It should be noted that items 1, 2, 4, 6, 9, 11, and 13 are scored reversely. The minimum possible score on this scale is 0, and the maximum is 64. A score of 0 to 21 indicates weak conscientiousness, a score of 22 to 32 indicates moderate conscientiousness and a score of 33 to 64 indicates strong conscientiousness (
21). Costa and McCrae’s Work Conscientiousness Scale has also been used in numerous studies, and its face and content validity have been confirmed in most of them. The reliability of the scale was reported as 0.76 by Gatley-Irwinel and 0.72 by Ezhei et al. (as cited by Imani et al.) in an Iranian sample (
21). In the present study, the reliability of the scale was calculated as 0.76 using Cronbach's alpha.
The participants in the situation simulation group watched a film on ethical challenges in nursing once a week for seven 30-minute sessions. The content of the films was approved by a group of experts and nursing professors. At the end of each session, the students were asked to complete a root cause analysis (RCA) form. Root cause analysis is the process of identifying the root causes of problems in order to find effective solutions for the same situation individually. The students in the reflection group also reviewed a written scenario of ethical issues similar to the films shown to the participants in the situation simulation group. After studying the scenario, they also completed a RCA form. Feedback was provided to the members of both groups by the researcher in each session.
Table 1 shows the content of the intervention sessions. The students in the control group received no training intervention.
| Sessions | Situation Simulation Groups | Reflection Groups | Duration |
|---|
| 1 | Missed care: A woman is hospitalized due to a complete burn on her right leg. She has asked the nurse several times since the beginning of the shift to help her change position, but each time the nurse was busy doing something else and the patient moved on the bed without help, enduring a lot of pain. | Missed care: A woman is hospitalized due to a complete burn on her right leg.

| 3 | Failure to comply with government regulations or abortion laws: A woman has just found out that she is pregnant. She has been admitted to the hospital due to a cold and shortness of breath. Due to financial problems, she has decided to have an abortion and does not want to inform her husband; because she knows that he won’t allow her to do so. Thus, she asks the nurse for advice on abortion, and the nurse introduces her to a center that performs illegal abortions. | Failure to comply with government regulations or abortion laws: A woman has just found out that she is pregnant.

To prevent the exchange of information between students in the three groups, students from different faculties and cities were placed in separate groups. The students were unaware of their group assignments (control or intervention) based on their faculties and were instructed not to share information with other students. After completing the final training session, participants in all three groups were asked to complete the items on the Work Conscientiousness Scale again. To comply with ethical protocols and ensure that no group was deprived of a beneficial intervention, participants in the control group were provided with the content of the intervention programs. Additionally, the content of the training interventions for the two intervention groups was shared between both groups.
The collected data were statistically analyzed using SPSS 24 software at a significance level of less than 0.05 (P < 0.05). The Shapiro-Wilk test was initially used to examine the normal distribution of the data. Descriptive statistics, including mean, standard deviation, frequency, and percentage, were used to summarize the data. Furthermore, inferential statistics, including the independent samples t-test, paired samples t-test, chi-square test, Fisher's exact test, and analysis of variance (ANOVA), were employed for analysis.
