<![CDATA[Background: Sharia-based nursing care emphasizes fulfilling patients’ biological, psychological, social, and spiritual needs by integrating the principles of maqashid sharia. Spiritual nursing diagnoses are an essential component as they influence patients’ recovery and quality of life; however, nurses’ ability to establish these diagnoses remains low. Purpose: To evaluate the effectiveness of mandatory training on sharia-based nursing on the ability to enforce spiritual nursing diagnoses. Method: A pre-experimental one-group pretest–posttest design was applied to 76 nurses at Sari Asih Ciputat Hospital who met the PK II/Sharia Nurse II criteria. Data were collected using pretest–posttest questionnaires and practice observation sheets, then analyzed using a paired t-test with a significance level of α = 0.05. Results: The mean pretest score of 54.27 (SD = 22.17) increased to 67.63 (SD = 16.98) after the intervention, showing a statistically significant difference (t = -12.292; df = 71; p < 0.001; 95% CI: -15.52 to -11.19). The proportion of nurses who could optimally establish spiritual nursing diagnoses increased from 54.2% to 83.4% after mentoring. Observation results also indicated consistent improvement in practical skills. Conclusion: These findings demonstrate that sharia-based mandatory training with mentoring is effective in improving nurses’ competence in spiritual assessment and diagnosis. Suggestion: The implementation of continuous practice-based training to strengthen nurses' spiritual competencies and improve the quality of nursing services based on Sharia.
