What is being measured

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

  1. Pictorial memory task

    Participants will be presented with 24 neutral, 24 positive and 24 negative photographs in a random order. Scores will be calculated by summing the correctly remembered photographs per valence.

    Measured: 25 minutes and 24 h after presentation

  2. Verbal memory task

    Six series of five semantically unrelated nouns will be presented.Total score is calculated by summing the number of correctly recalled words

    Measured: 25 minutes and 24 h after presentation

Secondary outcomes (7)
  1. Saliva cortisol level

    Samples are collected at different timepoints during the day in order to measure stress related cortisol activity. Participants have to chew a cotton sponge for 2-3 minutes, which then are contained in a special device

    Measured: 1 day after word/picture presentation Start /middle and end of day. Baseline cortisol 1-14 days later.

  2. Working memory

    Participants will have to calculate as many arithmetical means of seven one-digit numbers possible within two minutes by mental calculation.

    Measured: 1 day after word/picture presentation

  3. Visual Analogue Scale VAS test anxiety

    will be assessed between each task by the participant using a visual analogue scale. Respondents specify their level of agreement to the statement by indicating a position along a continuous line (10 cm).

    Measured: 1 day after word/picture presentation

  4. Visual Analogue Scale VAS confidence

    will be assessed between each task by the participant using a visual analogue scale. Respondents specify their level of agreement to the statement by indicating a position along a continuous line (10 cm).

    Measured: 1 day after word/picture presentation

  5. Visual Analogue Scale VAS interference

    will be assessed between each task by the participant using a visual analogue scale. Respondents specify their level of agreement to the statement by indicating a position along a continuous line (10 cm).

    Measured: 1 day after word/picture presentation

  6. Visual Analogue Scale VAS solicitude

    will be assessed between each task by the participant using a visual analogue scale. Respondents specify their level of agreement to the statement by indicating a position along a continuous line (10 cm).

    Measured: 1 day after word/picture presentation

  7. Visual Analogue Scale VAS excitement

    will be assessed between each task by the participant using a visual analogue scale. Respondents specify their level of agreement to the statement by indicating a position along a continuous line (10 cm).

    Measured: 1 day after word/picture presentation

Questions about this trial

What is this clinical trial studying?

A study testing High Epicatechin/ Melissa and Low Epicatechin/ Oat bran in people with Test Anxiety, run by Prof. Dominique de Quervain, MD at 1 site in Switzerland.

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 7 inclusion and 11 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 5 Sep 2018. 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 Switzerland. 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?

Pictorial memory task (time frame: 25 minutes and 24 h after presentation). The study lists 2 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 5 Sep 2018.
