What this trial studies

This clinical trial aims to enhance the decision-making abilities of older adults regarding recommended vaccinations, including seasonal influenza, pneumococcal, and COVID-19 vaccines. Utilizing a two-arm randomized control design, the study will implement interventions based on the Mental Models Approach and Patient Activation Approach to boost participants' confidence and self-efficacy in managing their health. Participants will be community-dwelling individuals aged 70 and above who have not consistently received vaccinations in recent years. Data will be collected through questionnaires at baseline and follow-up intervals of one and four months post-intervention.
