Brief summary

This study adopted a mixed-methods approach and was conducted in two exploratory phases. The first phase focused on development and involved three focus group interviews with community-dwelling older adults. These qualitative focus group discussions were used to inform the development of a dementia prevention education program based on the analysis results. In the second phase, community-dwelling older adults were recruited to participate in the study. The experimental group received the dementia prevention education program, while the control group received general health education leaflets. Participants were assessed before the intervention, immediately after the intervention, and again three months later. The assessments measured changes in dementia-related knowledge, dementia-related worry, health beliefs, and willingness to engage in preventive actions. This study aimed to examine the effects of the intervention on older adults' dementia knowledge, health beliefs, and willingness to undertake preventive actions.
