- Abstract: Behavioral and psychological symptoms of dementia (BPSD) and delirium superimposed on dementia (DSD) can lead to severe complications if they are not accurately identified and managed. Effective dementia care therefore requires clear differentiation, systematic assessment, and appropriate nursing interventions. This study aimed to develop VRDementia: BPSD/DSD, a virtual reality simulation program, and to qualitatively examine its validity and usability as a development-based pilot study. Methods: Using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), the program was systematically developed. During the analysis phase, qualitative interviews and literature reviews identified educational needs among nurses in long-term care hospitals. Key challenges included distinguishing agitation/aggression (BPSD) from hyperactive DSD, and depression (BPSD) from hypoactive DSD. Based on these findings, four case-based scenarios were created. Content validity and usability were qualitatively evaluated through semi-structured interviews with five experienced nurses (≥5 years of clinical experience). Results: The program consists of four sessions addressing agitation/aggression and depression (BPSD), and hyperactivity and hypoactivity (DSD). Nurses practice symptom assessment, therapeutic communication, physician reporting, and nursing interventions. The simulation is accessible via head-mounted display (HMD), mobile devices, and PC (including laptops). Qualitative feedback indicated that participants perceived the program as useful and applicable for dementia care education, including its potential use in interdisciplinary training contexts. Conclusion: VRDementia: BPSD/DSD is a valid, practical educational tool that improves nurses’ competence in distinguishing and managing BPSD and DSD. This program may contribute to higher quality dementia care in clinical settings.
