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.
This health education program is based on a Community-based Participants Research (CBPR) approach, which is a partnership approach that equitably involves community members and researchers in all aspects of the research process. Given the different cultural, professional or living background of Hong Kong residents, we think this simple, flexible and sustainable approach will effectively mitigate the COVID-19 risk in HK society,
An academic-community collaboration platform with several nongovernmental organizations (NGOs), companies and schools will be established before this study. They will work together to recruit participants, design and implement a series of educational programs aimed at controlling the spread of COVID-19 in the community.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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. |
|
| 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. |

| Community-based Health Education based on core intervention package | Behavioral | Community-based Health Education will potentially include the following three components:
Collaborators should design and implement health programs based on the core intervention package. |
| Measure | Description | Time Frame |

| Vaccination rates | The number of participants who received a new dose of COVID-19 vaccine over the total number of participants. | 3 months |

| The knowledge towards COVID-19 vaccine | The knowledge towards COVID-19 vaccine will be measured by 15 items in the self-administered questionnaire. All the items are binary- choice Items (1=Ture, 2= False). The total score ranged from 15 to 30 and a higher score indicates poorer knowledge towards COVID-19 vaccine. | 3 months |

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.

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.
|
| Health Information Sharing Group | Behavioral | Collaborators are encouraged to collect and share health information to the participants. Shared information should be previewed by researchers. |

| The hesitancy towards COVID-19 vaccine |
The hesitancy towards COVID-19 vaccine will be measured by Chinese version of adult Vaccine Hesitancy Scale (aVAS), which includes 10 items of 5-point Likert scale, ranging from least hesitant (1) to most hesitant (5). In total 3 of aVAS are negatively worded and 7 are positively worded. The total score of aVAS is 50 with a score higher than 25 indicated high vaccine hesitancy. |
| 3 months |
| Perceived confidence of COVID-19 vaccine | The confidence of COVID-19 vaccine will be measured by 11 items with 5-point Likert scale with "strongly disagree", "disagree", "neither agree nor disagree", "agree" and "strongly agree". The total score ranges from 11 to 55 with higher score indicating higher confidence of COVID-19 vaccine.. | 3 months |
| Perceived barriers of receiving COVID-19 vaccine | The perceived barriers of COVID-19 vaccine will be measured by 4 items with 5-point Likert scale with "strongly disagree", "disagree", "neither agree nor disagree", "agree" and "strongly agree". The total score ranges from 4 to 20 with higher score indicating higher perceived barriers of COVID-19 vaccine.. | 3 months |
| The amount of early testing | The amount of early testing will be measured by self-reported number of early-testing with rapid antigen testing (RAT) in a month. | 3 months |
| The levels of acceptability for early testing | The levels of acceptability for early testing will be measured by 3 items with 5-point Likert scale with "strongly disagree", "disagree", "neither agree nor disagree", "agree" and "strongly agree". The total score ranges from 3 to 15 with higher score indicating higher acceptability of early testing. | 3 months |
| The frequency of washing hands with soap or hand sanitizer | The amount of early testing will be measured by self-reported number of hand-washing behaviors with soap or hand sanitizer per day in the past week. | 3 months |
| The frequency of washing hands with alcohol-based hand rub | The amount of early testing will be measured by self-reported number of hand-washing behaviors with alcohol-based hand rub per day in the past week. | 3 months |
| The knowledge of proper self-protection | The knowledge of proper self-protection correctly will be measured 13 items in the self-administered questionnaire. All the items are binary- choice Items (1=Ture, 2= False). The total score ranged from 13 to 26 and a higher score indicates poorer knowledge of self-protection. | 3 months |
| Stress status | The Perceived Stress Scale (PSS-4) will be used to measure the stress level. | 3 months |
| Anxiety status | Generalized Anxiety Disorder (GAD-2) will be used to measure the level of anxiety. | 3 months |
| Depression status | The Patient Health Questionnaire-2 (PHQ-2) will be used to measure the depression status. | 3 months |
| Participants' satisfactory level | The participants' satisfactory level will be measured by asking the degree of satisfaction (1-10) in terms of vaccination, early-testing and self-protection. | 3 months |
