This study examined the experiences of South Korean nursing students in a psychiatric nursing class with consumer involvement. Data on 98 nursing students were collected in June 2021 and analysed using content analysis of participants' journals. Our qualitative study design adheres to the COREQ checklist for qualitative studies. Four main categories and subcategories were identified: (1) reflection, (2) learning, (3) preparation for the future, and (4) requirements. The findings demonstrated that applying consumer involvement to psychiatric nursing education is an innovative and effective strategy to correct negative prejudices among nursing students against people with mental illness.
