About this study

Official title: Metaphors to Enhance Antibiotic Appropriate Use Knowledge and Behaviours to Reduce Educational Disparities Among Chinese Parents: A Survey-experimental Study

A randomized controlled survey experiment was conducted from October to November 2024 to assess the effectiveness of metaphor-based health education in improving Chinese parents' knowledge and behavioural intentions regarding appropriate antibiotic use. A total of 866 parents from two Chinese provinces were randomly assigned to either a metaphorical message group (n = 432) or a conventional message group (n = 434). Metaphors included comparing antimicrobial resistance (AMR) to insect resistance to pesticides, improper antibiotic disposal to mercury battery pollution, and antibiotic-free foods to organic foods. Outcomes measured were AMR knowledge, willingness to pay (WTP) for antibiotic-free foods, and proper antibiotic disposal intention.

Read the detailed description

To assess the influence of metaphorical and conventional health education messages on the AMR-related knowledge and behavioural intentions of rural and urban residents, the investigators conducted a survey experimental study across two provinces in China. Prior to receiving any health education message, the respondents completed questions on AMR-related knowledge, behaviours, and behavioural intentions. Subsequently, participants were randomly assigned to read either metaphorical or conventional health education messages. Following the reading of assigned message, the respondents once again completed the questions on AMR-related knowledge and behavioural intentions.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • metaphorical messagesBehavioural

    We created three specific pairs: the first explained mechanisms of AMR, comparing resistant bacteria to pesticide-resistant insects. The second addressed environmental contamination by likening antibiotics to mercury batteries. The third used the analogy of "organic" food to convey the concept of antibiotic-free animal foods. All metaphorical messages were reviewed by a panel of experts in public health, clinical microbiology, health communication, and health education to ensure factual consistency and clarity.

  • conventional messagesBehavioural

    The conventional messages were adapted from formal health communication sources, such as the World Health Organization and the Chinese National Health Commission, and retained the technical tone typical of official health education materials (China NHC, 2010; He, 2018; WHO, 2022).

metaphorical messages groupExperimentalThe metaphorical messages, by contrast, were crafted to be more accessible, drawing on familiar daily-life analogies derived from our prior qualitative research. We created three specific pairs: the first explained mechanisms of AMR, comparing resistant bacteria to pesticide-resistant insects. The second addressed environmental contamination by likening antibiotics to mercury batteries. The third used the analogy of "organic" food to convey the concept of antibiotic-free animal foods.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. knowledge

    Three items were summed to form the AMR-related knowledge scale. This scale was assessed by asking respondents to judge the correctness of the following statements before and after their first exposure to health education message: (1) Does antimicrobial resistance imply that bacteria are becoming increasingly difficult to kill with antibiotics? (2) Dose overuse of antibiotics lead to antimicrobial resistance? (3) Can antimicrobial resistant be transmitted between people?

    Measured: Immediately after the 30-second message exposure.

  2. Willingness to pay for antibiotic-free animal food

    Respondents were asked whether they were willing to pay a higher price for antibiotic-free animal foods compared to regular animal- foods. Their answers were dichotomized into "Yes" and "No/Not Sure".

    Measured: Immediately after the 30-second message exposure.

  3. antibiotic disposal intention

    To evaluate antibiotic disposal practices, participants were asked to recall how they had handled expired or unused antibiotic prior to receiving a third exposure to health education message.

    Measured: Immediately after the 30-second message exposure.

Questions about this trial

What is this clinical trial studying?

A study testing metaphorical messages and conventional messages in people with Antimicrobial Resistance, run by Bo Yan at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

knowledge (time frame: Immediately after the 30-second message exposure.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2026.
