Brief Summary

This study evaluates the community-based health education program in improving early testing for COVID-19, increasing vaccination acceptability and enhancing emergency preparedness and self-protection measures against COVID-19 in HK. We established a partnership with several local community stakeholders and they will be responsible for recruiting participants and implementing educational programs. Half of the community collaborators will receive the core intervention package, and use it as education material. The other half will be encouraged to self-collect and send health information to the participants.

Community-Based Health Education Group

EXPERIMENTAL

The collaborators will design the Community-based education approach (based on the core intervention package). Collaborators will be required to submit a brief standardized proposal to the academic investigators for review and approval, to ensure that all intervention programs have the same core intervention content and can be implemented appropriately. Collaborators will be able to use any reasonable strategies, such as social media platforms, information technology, posters, leaflets, and videos, to implement the programs . The use of incentives will be encouraged to improve participation. Each programs will last for 3 months. A booster session will be conducted at the mid of the intervention.

Behavioral: Community-based Health Education based on core intervention package

Health Information Sharing Group

ACTIVE COMPARATOR

The collaborators will design the community-based education approach and deliver health information to the participants. Researchers will provide some information, while collaborators need to self-collect the rest. Collaborators also need to submit a proposal to ensure the feasibility of intervention programs and the accuracy of health information. Collaborators can use any reasonable strategies to implement the programs . The use of incentives will be encouraged to improve participation. Each programs will last for 3 months. A booster session will be conducted at the mid of the intervention.

Interventions

Community-based Health Education based on core intervention package BEHAVIORAL

Community-based Health Education will potentially include the following three components: 1. A manual of emergency preparedness and self-protection against COVID-19 infection. The main content will include hand washing, mask wearing and social distancing guidelines. 2. Early testing. Participants will be trained on how to recognize the early symptoms of COVID-19 and appropriate practice to take in a response, and they will be provided with testing resources. 3. Knowledge of vaccines and their benefits and resources for vaccination. Collaborators should design and implement health programs based on the core intervention package.

Community-Based Health Education Group

Health Information Sharing Group BEHAVIORAL

Collaborators are encouraged to collect and share health information to the participants. Shared information should be previewed by researchers.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: PARTICIPANT
• Masking Details: All the participants will be blind to the allocation. Participants in the intervention group will receive intervention based on core package, while participants in the control will receive health information which are collected and provided by collaborators. The collaborator also will be told to avoid discussing allocation with the participants.
• Purpose: PREVENTION
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Assistant Professor

Model Details: The participants recruited by one collaborator will be considered as one cluster. A research assistant will randomly assign the clusters from the NGOs, Schools, and Companies to either the intervention group or the active control group, respectively. After allocation, there will be four clusters in both the intervention and control groups from the NGOs, schools and companies, respectively. This will result in 3 × 4 = 12 clusters for each group (intervention/control). A active control group will be used instead of a standard control group to help motivate the collaborators to implement the program and to avoid a high participant dropout rate.
