Brief Summary

Introduction: The COVID-19 vaccine is an effective measure for preventing and controlling COVID-19 epidemics, and the World Health Organization lists older adults as a high-priority group for COVID-19 vaccination. However, the willingness of older people to be vaccinated against COVID-19 remains an important issue in achieving herd immunity. We investigated the effectiveness of a COVID-19 vaccine intervention for older adults, based on self-determination theory. Methods and analysis: Questionnaires were administered to assess vaccine willingness at baseline and at 6 weeks following educational intervention programs concerning vaccination against COVID-19. Four nursing homes with a population size of over 100 will be selected and randomized into intervention and control groups. The control group will undergo conventional intervention methods, and the intervention group will undergo a comprehensive intervention program based on self-determination theory. Ethics and dissemination: The study has been approved by the Ethics Committee of Taizhou Hospital, Zhejiang Province, China (approval number: K20230832).

Study Arms (2)

Control group: traditional health education

OTHER

In the control group, a conventional intervention will be used, and health education brochures on the COVID-19 vaccine will be distributed for the study participants to read on their own time. The contents of the brochure included basic knowledge concerning the SARS-CoV-2 coronavirus, COVID-19 vaccine, herd immunity, and precautions for vaccination.

Other: Self-determination theory-based health education measures

Intervention group: Self-determination theory-based health education measures

OTHER

The intervention group will receive self-determination theory-based interventions, with targete interventions proposed based on the self-determination theory-including health-related talks and sharing sessions. To ensure that older individuals with varying levels of literacy understood the intervention, the process will be conducted in the local native dialect.
