Research involvement and engagement is a vital aspect of nursing practice. However, research in dementia care remains limited compared to research focused on finding a cure, presenting a significant gap that specialist dementia nurses (Admiral Nurses) can help bridge by participating in research themselves and facilitating recruitment to research. This study aimed to assess the research involvement and support needs of Admiral Nurses and identify factors affecting their participation in research. This research is particularly timely as Dementia UK has launched its first research strategy, which necessitates strengthening research capacity within Admiral Nursing. We used a mixed methods convergent parallel synthesis design, simultaneously collecting quantitative and qualitative data. An online survey was conducted in January 2023, targeting current Admiral Nurses across the United Kingdom. The survey included questions addressing demographics, research experience, goals, barriers, facilitators, and support needs. Data analysis involved descriptive statistics, frequencies, univariate analyses, and thematic analysis. A positive relationship was found between the highest level of academic achievement and current or previous research involvement, as well as interest in becoming involved in research in the future. Although most nurses recognized the importance of research, only half reported current or past research involvement, indicating a need for increased support. A lack of access and opportunities for peer discussion hindered engagement with research findings. Time constraints, lack of support, and low confidence were major barriers to research involvement. Support needs varied but included mentorship, coaching, and the potential for a community of practice for research. This survey of Admiral Nurses sheds light on their research involvement, support needs, and barriers to participation. Recognizing the significance of research while identifying challenges and support requirements is crucial for enhancing research capacity among these specialized nurses. This study contributes valuable insights into the world of specialist dementia nursing and lays the foundation for future strategies to increase research engagement in this field.
