Background: Humanitude® is a multimodal care communication methodology grounded in a humanistic philosophy emphasizing respect for human dignity. Although originally developed for healthcare professionals, its applicability may extend to the general public. This study evaluated the effectiveness of Humanitude online courses designed for community residents.

Methods: A survey was conducted among participants in the “Humanitude Certified Supporter” program between 2023 and 2025. Data from 419 participants before the course and 264 after course completion were analyzed. Outcomes included communication confidence, dementia-related stigma (PDSA-J), attitudes toward people with dementia, and positive appraisal of caregiving.

Results: Communication confidence improved significantly after course completion, with median scores increasing from 5 to 7 (p < .001). Significant improvements were also observed in dementia-related stigma, particularly in Avoidance, Fear of Diagnosis, and Respect. Positive attitudes toward people with dementia improved in the domains of Tolerance, Familiarity, and Rejection. In addition, all domains of positive appraisal of caregiving—meaning, mastery, positive emotion, and support—showed significant enhancement. No significant changes were observed for Fear of Discrimination or Sense of Distance.

Conclusion: Humanitude-based education enhanced communication confidence and promoted more positive attitudes toward dementia among members of the general public. These findings suggest that citizen education combining a coherent care philosophy with concrete communication skills may contribute to the development of dementia-friendly communities.
