Purpose: The purpose of this study is to examine the effectiveness of a reflection sheet for general ward nurses focusing on older adults as more-being． Methods: The study design used the case study method. First, we applied the reflection sheet to seven nurses who provided care to older adults in a general ward for two months. Next, the contents of nurses’ written reflection sheets and reflections from semi-structured interviews with nurses were then summarized for each case. Finally, the newly learned information, discoveries, and changes in thinking and perception that occurred through the reflection process were categorized qualitatively. Results: As a result of applying the reflection sheet for nurses, five categories of outcomes were identified: “self-understanding,” “awareness of the older adults,” “change in attitude,” “preparing for practical application,” “commitment to practice.” Comparing the questions on the reflection sheet with the case scenario led to changes in nurses’ perceptions of the older individuals’ reactions and their relationships. Conclusion: The effectiveness of this reflection sheet was confirmed as the nurses have newly learned information, discoveries, and changes in thinking and perception, and have gained an awareness of the meaning and value of their relationships with the older adults. On the other hand, issues such as insufficient depth of reflection and difficulty in comparing the effects of reflection with practice were identified. To provide more effective and practical support to nurses, this study proposes the creation and facilitation of a system that can be reflected throughout the ward.
