Background:The nurses’ moral sensitivity is the first step to make right decisions in difficult moral situations. Therefore, its education and promotion is highly important.Research objectives:The aim of this study was to examine the impact of poetry-based ethics education on the nurses’ moral sensitivity.Research design and methods:This was a semi-experimental study. The sample consisted of 108 nurses who were selected by convenience sampling method and randomly assigned to three groups: intervention with poetry (G1), who read a booklet about values and principles (...) of professional ethics as well as poems related to these subjects for 1 month; intervention without poetry (G2), who only read the booklet without any poetry; and control group (G3), who did not receive any intervention. Data were collected by Moral Sensitivity Questionnaire that was completed by the participants prior to the intervention (T1), 1-month post-intervention (T2), and 2-month post-intervention (T3). Data were analyzed by SPSS 16 software.Ethical considerations:This study was conducted in accord with the principles of research ethics and regulations relating to informed consent.Findings:Changes in the mean score of total moral sensitivity were significantly higher in G1 than in G2, which was in turn significantly higher than in G3. This increase was significant from T1 to T2 and T2 to T3 (P < 0.001). In all subscales, there was a significant difference between the mean changes in the three groups, so that in these subscales, the mean changes in G1 were significantly higher than those in other groups.Discussion:In line with previous studies, our results showed the effectiveness of poetry-based education on the transfer of educational concepts and increase moral sensitivity scores with greater lasting effect.Conclusion:The use of interdisciplinary subjects such as poetry, due to its entertaining, fun, and lasting effect on minds; level of awareness; and actions of nurses, can help raise nursing moral sensitivity.
