Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study has two intervention factors, each with two levels delivered in a 2x2 factorial arrangement.
Factor 1: Who is providing the message (General Practitioner versus Community Representative).
Factor 2: How the message is delivered (Animation versus Talking Head).

Each participant will be exposed to each of the four combinations of these factor levels across four different messaging contexts. These contexts are:
1. Getting your booster vaccine
2. Wearing a mask outdoors when you can’t physically distance
3. Staying at home when you have a new cough symptom
4. Using QR check in codes when required

Provision of these intervention combinations across these different contexts is enabled through our "helix", counterbalanced randomised trial design. A Latin square approach has been used to order the exposure of participants to each intervention level combination to eliminate study level order effects.

Each intervention will be delivered as a pre-recorded video and all informational material related to each context area will be provided in this format. Each video will be of approximately 1-2minutes duration. Each participant will be exposed to all levels 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 20minute period. Participants will observe the videos either 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 each 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. General Practitioner 'talking head' visual stimulus delivered health message versus Community Representative 'talking head' visual stimulus delivered health message
2. General Practitioner animation visual stimulus delivered health message versus Community Representative animation visual stimulus delivered health message
3. General Practitioner 'talking head' visual stimulus delivered health message versus Community Representative animation visual stimulus delivered health message
4. General Practitioner animation visual stimulus delivered health message versus Community Representative 'talking head' visual stimulus delivered health message

Comparisons are not being made between context areas as 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] 331073 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.Now that you have watched the video, please indicate if it has made you feel more or less inclined to have a further dose of the COVID-19 vaccine (when you become eligible to receive it). This includes a 4th dose if you have already had 3 doses.
2. Has viewing this material made you feel more or less inclined to wear a mask outside when you are unable to socially distance?
3. Has viewing this material made you feel more or less inclined to spend time with people you do not live with if you were to develop a cough (but that was the only issue)?
4. Has watching this material made you feel more or less inclined to use QR code check-ins every time you visit a venue if there were to be a future pandemic like the COVID-19 pandemic?
Timepoint [1] 331073 0
Immediately following viewing the intervention.
Primary outcome [2] 331074 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 having a COVID-19 vaccine booster (3rd dose), how likely would you be to encourage them to get the vaccine?
2. If you had a family member or friend who was unsure about whether they should wear a mask outside if they are unable to socially distance, how likely would you be to encourage them to wear one?
3. If you had a family member or friend who was unsure about spending time with people they do not live with if they developed a cough (but that was the only issue), how likely would you be to encourage them to stay away from other people while they had a cough?
4.If you had a family member or friend who was unsure about using QR code check-ins every time they visited a venue in a future pandemic, how likely would you be to encourage them to use QR code check-ins?

Timepoint [2] 331074 0
Immediately following viewing the intervention.
Secondary outcome [1] 408645 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: I felt strongly represented in this video.
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.

Question 1: Immediately following viewing the intervention.
Question 2: At the end of all interventions delivered (end of survey).

Study design
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)
Who is / are masked / blinded?



Intervention assignment
Other
Other design features
This design will use a "helix" counterbalanced design, involving factorial allocation of two interventions each with two levels (2x2 factorial) across four context areas. The ordering of presentation of intervention combinations to participants will follow a Latin square pattern to eliminate study level order effects.

For more information on helix counterbalanced designs please refer to:

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 vulnerable participants subgroups, and context areas.
