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.

Decisional Conflict Scale, low literacy version
Higher scores indicate worse outcomes (min = 0; max = 100).
Time frame: through study completion, an average of 20 minutes
Decision Self-Efficacy scale
Higher scores indicate better outcomes (min = 0; max = 100).
Time frame: through study completion, an average of 20 minutes
Preparation for Decision Making scale
Higher scores indicate better outcomes (min = 0; max = 100).
Time frame: through study completion, an average of 20 minutes
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.
Time frame: through study completion, an average of 20 minutes
