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
Participants will have access to the Editor (https://shell.techlab.works/ ) and self-directed training materials. The Editor is an online browser-based tool that helps users develop text-based health education materials that adhere to health literacy guidelines. The Editor comprises six assessments: readability, complex language, passive voice, text structure, lexical density and diversity, and person-centred language. These are each presented as global scores, with additional, more specific feedback flagged in the text itself. Several training resources embedded within the intervention include:
1. Help page: The Editor’s help page containing instructions, video tutorials and worked examples
2. Self-check tool: 5 questions to check understanding of key concepts (available from the help page)
3. Quick start guide: A 2-page PDF introducing key concepts (available from the help page)

Participants in this group will also be invited to take part in a 30-minute Zoom call administered by a member of the research team. Participants will be introduced to the tool and any relevant training resources, with opportunity to ask questions. If participants are not able to make the Zoom meeting they will have access to a recording of the same content. Zoom attendance / evidence of viewing of the recording will be used to monitor adherence to the intervention.

After completing training, participants in the intervention group will be sent a link to the text revision task. They will receive reminders at 1 and 2 weeks if the task has not been completed.

During the text revision task, participants are provided with the following instructions: Your task is to revise each of the texts below so that they are easy for most people to understand. Try to:
• make the text simpler (aim for Grade 8 to 10)
• make sure that the take-home messages stay the same.
Participants are asked to set aside 40 minutes for this part of the study.

Participants in the intervention group are also instructed to use the Editor to help them revise the text.

As stated in the outcomes, participants in the intervention group will also be asked to self-report which features they used within the Editor (e.g. readability, complex language, passive voice)

Treatment: Other
Comparator / control treatment
Participants will be asked to use their usual processes to revise the text. No training is provided prior to the task revision task. Examples of usual processes include revising text based on Microsoft Word grade reading score, only readability calculators, and using thesauri to identify simpler alternatives.

Participants in the control group will be sent a link to the text revision task. They will receive reminders at 1 and 2 weeks if the task has not been completed.

During the text revision task, participants are provided with the following instructions: Your task is to revise each of the texts below so that they are easy for most people to understand. Try to:

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation takes place via the online survey platform Qualtrics and is therefore concealed from all investigators.
