Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This trial is a "helix" counterbalanced randomised trial design. Participants are randomly ordered to receive two interventions across two different context areas related to COVID-19 health.
The two arms of the study are:
1. Conversational training approach provided by a General Practitioner ('talking head').
2. Direct information provision provided by a General Practitioner ('talking head').

The two context areas are:
1. Encouraging people to ask workers attending their home if they are vaccinated or not
2. Encouraging people to avoid sharing food, utensils etc. at gatherings.

The arms of study differ by the language and tone. The conversational training approach provides a health message (one of the two context areas mentioned above), in a peer-to-peer fashion that is more about giving advice. The Direct information provision arm, provides a health message that is direct and more one-sided in tone.
Each intervention will be delivered as a pre-recorded video. Each video will be of approximately 1-2minutes duration. Each participant will be exposed to both arms of the intervention, with each intervention level being presented in a different context area as per a counterbalanced 'helix' trial approach (DOI: https://doi.org/10.1186/s13012-019-0896-0).
It is anticipated that these videos will be observed over an approximate 10minutes period. Participants will observe the videos in their own home or at a partner organisation service provider location relative to their vulnerable population subgroup (e.g. meeting place for our ATSI subgroup).
Progression of the participant through both of the intervention/context combinations will be monitored via the online data collection platform (Qualtrics). Qualtrics enables extraction of all responses including partial completions, and allows tracking and recording of in-complete survey entries.

Behaviour
Comparator / control treatment
The comparators in this study are the different levels of the interventions.
Specifically we will be comparing:
1. the effectiveness of health information provision delivered through a conversational training approach by a General Practitioner and through a direct information provision approach by a General Practitioner.
Comparisons are not being made between context areas a part of the primary analysis, however, we will investigate interaction effects of the different intervention comparisons across the different context areas so that we can understand whether certain interventions work better in certain contexts.

Outcomes
Primary outcome [1] 331102 0
Stated intention to undertake a context specific behaviour with responses scaled using a 5 point Likert scale ('much less inclined', 'less inclined', 'about the same', 'more inclined' and 'much more inclined').
The specific questions for each context are:
1. Has viewing this video made you feel more or less inclined to ask a person visiting your home for work if they have had a COVID-19 vaccine before allowing them to enter? Since watching the video, I feel:

2. Has viewing this video made you feel more or less inclined to bring your own plates, cutlery, cups and utensils to social gatherings? Since watching this video, I feel:

Timepoint [1] 331102 0
Immediately following viewing the intervention
Primary outcome [2] 331103 0
Stated intention to encourage family or friends to undertake a context specific behaviour scaled using a 5 point Likert scale ('extremely unlikely', 'unlikely', 'neutral', 'likely', 'extremely likely').
The specific questions for each context are:
1. If you had a family member or friend who was unsure about asking people visiting their home to work whether they have had a COVID-19 vaccine before letting them enter, how likely would you be to encourage them to do so?

2. If you had a family member or friend who was unsure about whether people should bring their own plates, cups, and utensils to social gatherings, how likely would you be to encourage them to bring their own?
Timepoint [2] 331103 0
Immediately following viewing the intervention.
Secondary outcome [1] 408745 0
Stated feelings of inclusion and representation in the developed video for each context area and how this correlates with level of agreement of the message in the video. Responses scaled using a 5 point Likert scale ('strongly disagree', 'disagree', neither agree nor disagree', 'agree', 'strongly agree'). The specific questions measuring this include:
1. We would like to further understand how well represented you felt in this video. Please indicate how much you agree to the following statement.
2. We are interested in understanding in how much feeling like you are strongly represented in a health message video makes you more likely to agree with the message in the video.
Please indicate how much you agree with the following statement: I am more inclined to agree with the message in a health video if I feel strongly represented in it.
Timepoint [1] 408745 0
Question 1: Immediately following viewing the intervention involving a video.
Question 2: At the end of all interventions delivered (end of survey).

Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Qualtrics data collection platform has an inbuilt randomisation function. Therefore, random allocation will be fully concealed from participants and investigators involved in recruitment and data collection.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
In built random allocation sequence within Qualtrics data collection platform.
Masking / blinding
Open (masking not used)

Other design features
This design will use a "helix" counterbalanced design including 2 intervention arms across 2 different context areas related to COVID-19 health. The ordering of presentation of intervention combinations is randomly assigned through the Qualtrics data collection platform.

Efficacy
Statistical methods / analysis
Linear mixed model analyses will be used treating the intervention levels as fixed factors, participants as random factors. Context will be ignored when investigating intervention main effects as it will be balanced across the different intervention levels. Interaction effects will be investigated to explore impacts of intervention combinations (simple effects), while also exploring interactions of main effects and simple effects across context areas.
Through our analysis we aim to:
1. Compare the effectiveness of health information provision delivered through a conversational training approach by a General Practitioner and through a direct information provision approach by a General Practitioner.
