Nursing involves spiritual, physiological, psychological, and social care. Understanding the impact of art on nursing students' perceptions of peace and spiritual care is essential. This descriptive study investigated how nursing students perceived peace and spiritual care after attending a decorative arts course. The research was conducted between June and July 2022 with a sample of 140 nursing students from a university in Türkiye. Data were collected using a personal information form, the Peace Scale, and the Spiritual Care-Giving Scale. Participants who had taken the "Decorative Arts" course for two terms had a significantly higher mean Peace Scale score than those who had taken it for one semester or had never taken it (p = .001).. Similarly, they had significantly higher mean scores on the Spiritual Care-Giving Scale. In particular, they scored higher on the 'attributes for spiritual care,' 'spiritual care attitudes,' and 'spiritual care values' subscales compared to those who had taken the course for one semester or had never taken it (p < .001). The "Decorative Arts" course positively influenced nursing students' perceptions of peace and spiritual care, highlighting the potential role of artistic engagement in nursing education.
