Text box 1. Contributions to the literature |
---|
• Community-Based Dementia Prevention Feasibility: This study pioneers community-level dementia prevention with insights into adapting multi-domain interventions for older adults. |
• Implementation Science Framework: Employing the Framework for Reporting Adaptations and Modifications-Enhanced (FRAME), this study advances the systematic adaptation of evidence-based programs to unique community contexts. |
• Barrier Mitigation for Implementation: This study identifies and tackles barriers, including resource constraints and local challenges, enhancing the potential for effective dementia prevention programme delivery. |
• Potential Global Impact: By emphasizing feasibility and adherence, this study contributes to the groundwork for extending healthy aging and improving older adults’ quality of life, potentially influencing future global dementia prevention efforts. |

Step name | Status |
---|---|
1. Conduct a needs assessment | Conducted interviews with J-MINT officials, Obu City department heads (health and welfare, planning, and community development), and public health nurses |
2. Consult with experts | The authors of this article developed the original intervention and discussed it with the team, including experts in implementation science. |
3. Consult with stakeholders and review assessment data to determine most appropriate and effective EBI | Discussed appropriate EBI to be implemented with frontline public health nurses and community volunteers |
4. Decide what needs adapting | Research team and community health nurses Identified items for adaptation within the FRAME |
5. Adapt the original EBI | |
6. Train staff | Staff and volunteers have been trained |
7. Pilot and test the adapted materials | Will be implemented |
8. Evaluate | Will be implemented |
Domain/project | Original (J-MINT) programme/provider | Community (Adapted) programme/provider | (1) Who/when decided, (2) What modified, (3) Rationale |
---|---|---|---|
No./frequency of interventions | 1½ years, weekly (78 sessions) | 1 year, every 2 weeks (26 sessions) + exercise classes provided by the local municipality (26 sessions) | (1) At the time of protocol development/municipality and research team collaborated (2) Shortening of period: 1½ years → 1 year (3) To match the municipality’s fiscal year (1 year) |
Place of intervention | Dedicated studios in hospitals | Community centre | (1) At the time of protocol development/municipality (2) Change to a location more appropriate to the local context (less space and comfort but better accessibility) (3) To increase the possibility of wide-scale uptake in the region |
Exercise instruction methods | Face-to-face guidance + instruction tailored to cognitive and physical functions of subjects/trained instructor | Face-to-face instruction (video + MCI handbook) + instruction tailored to cognitive and physical functions of subjects/trained instructor | (1) During protocol development/municipalities and research team (2) Use of videos and MCI handbook (3) Development of a video and booklet to standardise the J-MINT research experience |
Exercise intensity | Moderate (monitored by heart rate) | Moderate (monitored by subjective symptoms) | (1) At the time of protocol development/municipality and research team (2) Change the monitoring method (no change in intensity) (3) To reduce the cost of monitoring and increase the possibility of wide-scale uptake in the community |
Nutrition guidance | Nutrition quiz + interviews and telephone support/registered dietitian | Nutrition quiz + MCI handbook/trained instructor | (1) During protocol development/municipality and research team (2) Change to instructor/use of MCI handbook (3) Municipalities already offer individual guidance and telephone support. Additional use of the MCI handbook will provide basic nutritional knowledge and facilitate monitoring in a standardised manner. |
Cognitive training | Brain HQ/self-conducted | Introduction to cognitive training + MCI handbook/trained instructor | (1) During protocol development/research team (2) Changed to a more economical intervention (3) To reduce the cost of training and increase the possibility of wide-scale uptake in the community |
Lifestyle-related disease management | Regular medical examination/primary care physician | Provision of information by MCI handbook + recommendation for medical check-ups based on medical check-up data/public health nurse | (1) At the time of protocol development/local government + research team (2) Change to municipal initiative/use of handbook (3) Continuity can be ensured if local governments provide recommendations for medical check-ups |
Social participation | Self-monitoring | Monitoring + group work/implemented by self and shared with the group | (1) During protocol development/research team (2) Additional group work (3) Sharing among participants fosters interaction and sustainability, which in turn reinforces behavioural change. |
Provision of health information | Providing information in brochures/research staff | Providing information using MCI handbook/trained instructor | (1) During protocol development/research team (2) Use of MCI handbook (3) MCI handbook provides comprehensive knowledge of dementia prevention |
