About this study

How health-related information is communicated affects what is understood and might influence how people make decisions and how confident they feel in participating in clinical shared decision-making.

The CICERO trial will compare three different communication tools providing information on fictional interventions for a common medical problem (i.e. social anxiety disorder) both in terms of how well interventions work (benefit) and also possible harms associated (risk). The three communication tools ("Summary of Findings table", "Kilim plot", and "Vitruvian plot") differ in how they present information: exclusively written, primarily written and partially graphical, or mixed written and visual. Each participant will be asked to go through one clinical scenario.

The investigators will ask participants to familiarise themselves with the tool they have been allocated to (either a plot or a table) and then answer some validated questionnaires to measure how useful and efficient the communication strategy was.

The entire study occurs online in a single study session (about 20 minutes).

The results of the CICERO trial will inform how to communicate research findings to the general population, facilitating their implementation in clinical shared decision-making.

What is being measured

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

  1. Decisional Conflict Scale, low literacy version

    Higher scores indicate worse outcomes (min = 0; max = 100).

    Measured: through study completion, an average of 20 minutes

Secondary outcomes (3)
  1. Decision Self-Efficacy scale

    Higher scores indicate better outcomes (min = 0; max = 100).

    Measured: through study completion, an average of 20 minutes

  2. Preparation for Decision Making scale

    Higher scores indicate better outcomes (min = 0; max = 100).

    Measured: through study completion, an average of 20 minutes

  3. Information comprehension (proportion of participants providing a correct answer)

    Participants will be asked to choose one of multiple (fictional) medical interventions based on their characteristics as part of the clinical scenario. The question related to the clinical scenario allows only one correct answer.

    Measured: through study completion, an average of 20 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Vitruvian plot, Kilim plot and Summary of findings table in people with Knowledge, Attitudes, Practice and Literacy, run by University of Oxford at 1 site in United Kingdom.

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 0 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 18 Dec 2023. 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 United Kingdom. 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. 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?

Decisional Conflict Scale, low literacy version (time frame: through study completion, an average of 20 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05917639, which also lists 1 linked publication.

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 18 Dec 2023.
