About this study
Official title: Risk Literacy Among Portuguese Medical and Dentistry Students - a Cohort Study
This study is an online survey to assess risk literacy among students of the medical and dentistry faculties in Portugal. Risk literacy is the capability to understand and interpret statistical information, based on simple rules of thumb.
The investigators assess the level of "medical risk literacy" among Portuguese medical and dentistry students with the Quick Risk Test (QRT) and the multiple choice version of the Berlin Numeracy Test (BNT).
Read the detailed description
This study is an online survey to assess risk literacy among students of the medical and dentistry faculties in Portugal.
The primary outcome is the measurement of "medical risk literacy" among Portuguese medical and dentistry students as assessed with the Quick Risk Test (QRT) and the multiple choice version of the Berlin Numeracy Test (BNT).
Secondary outcomes is to investigate whether study year, faculty, and prior statistical education have an impact on the level of risk literacy. Participants will be invited via email through established faculty mailing lists or established social media channels. For the survey, an online-survey tool (Unipark, academic program or Questback) will be used. Participation is voluntary and can be withdrawn at any time by aborting the survey (e.g. via closing the browser). Informed consent will be acquired at the beginning of the survey. English and Portuguese versions will be available to the participant.
As incentive to participate, participants completing the brief (ca.15 minutes) online-questionnaire will be granted a free subscriptions to the AMBOSS medical learning platform (2 weeks) and have the option to be entered into a lottery with the possibility of winning one of 3 free 6 month subscriptions.
After completion of the questionnaire, participants will be re-directed to a dedicated AMBOSS website where they can enter their email-address to take part in the lottery. This assures strict separation of the anonymous experimental data and the AMBOSS subscription data. Prior to initiation of the questionnaire, in the invitation email, participants will be provided the full participant information and made aware that, due to anonymity, it will not be possible to retrospectively delete their responses once the survey has been completed.
As the primary outcome is a baseline assessment and the secondary outcomes are exploratory analyses, no hypotheses will be tested in this survey.

Questions about this trial
What is this clinical trial studying?
An observational study of Medical Education and Decision Support Techniques, run by Harding Center for Risk Literacy at 1 site in Germany.
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 3 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 17 Feb 2021. 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 Germany. 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?
Quantitative measurement of "medical risk literacy" (time frame: 1st - 30st of May 2020). 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 NCT04380428, which also lists 10 linked publications.
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 17 Feb 2021.
