Background: Nurses are involved in providing end-of-life care for end stage individuals and their self-efficacy is one of the key factors bearing on such care. The purpose of this study was to determine the effect of palliative care on perceived self-efficacy of the nurses. Methods: This is a quasi-experimental study with pretest-posttest design. Sampling was randomized and included 40 individuals. The intervention consisted of palliative care training for four sessions, each lasting 45 min. Data were collected using demographic and perceived self-efficacy questionnaires completed before and after the intervention. Data were then analyzed by SPSS 16 software using descriptive and inferential statistics. Results: The mean age of the participants was 38.6 and their work experience was 14.25 years. The majority of the participants were female (85%) and had a bachelor level of education (92.5%). The findings showed that "perceived self-efficacy", "psychosocial support" and "symptom management" improved significantly after intervention (p < 0.05). Conclusion: Based on the results, palliative care education has the potential to increase nurses' perceived self-efficacy. Since all members of the health care team Including nurses play an important role in providing palliative care, nursing managers can take an effective step to maximize the capacity of nurses by planning and supporting training in this regard.
