Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomly assigned to receive one of the interventions below, or the comparator.

1. Infographic style information about how to use ChatGPT safely for health questions available as image carousel within the online survey (time to view <5 mins)
2. Short (<5 min) animation about how to use ChatGPT safely for health questions
Content for both interventions covers the potential risks of using ChatGPT for health information, advice about which kinds of health questions may be less risky, and strategies for reducing these risks e.g. accessing multiple information sources.

For all intervention groups including comparator:
Delivered online via online survey in a single instance. Survey completion will be used to monitor adherence.

Time to complete survey is approx 15 minutes.

Efficacy
Statistical methods / analysis
Statistical analysis will be conducted using planned contrasts between the two intervention arms and control arm, implemented in regression models. The influence of age, gender, language, education, health literacy, self-assessed health status, and the presence of pre-existing or chronic health conditions, will be examined by including appropriate interaction terms within the regression models. The total sample size required is 567. This is based on an expected small effect size of 0.15 for the primary outcome. The number of participants required per arm (3 arms), to provide 90% power at error type I (alpha of 0.05) is 189 (this is a balanced design).
