What participants receive

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

  • olfactory assessmentBehavioural

    determination of olfactory sensitivity through olfactory threshold assessment (butanol) determination of hedonicity and intensity of 16 usual odors

  • image visualizationBehavioural

    20 images (from the IAPS-international affective picture systems) are presented to the subject. He has to determine the hedonicity of each picture.

  • psychophysiological assessmentBehavioural

    during the olfaction assessment and the image visualization, skin conductance reactivity (SCR) is recorded to assess unconscious emotional reactivity

Study groups in NCT02857088
Study groupRoleWhat they receive
depressed patientsExperimentalpatient with a current unipolar major depressive disorder intervention: olfactory assessment, image visualization and psychophysiological assessment
Receives: Behavioral: olfactory assessment; Behavioral: image visualization; Behavioral: psychophysiological assessment
non depressed subjectExperimentalsubject without a current unipolar major depressive disorder intervention: olfactory assessment, image visualization and psychophysiological assessment
Receives: Behavioral: olfactory assessment; Behavioral: image visualization; Behavioral: psychophysiological assessment

What is being measured

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

  1. hedonicity score of visual stimuli

    it will be compared between depressed and non depressed subjects.

    Measured: up to 1 month

  2. skin conductance reactivity amplitude

    it will be compared between depressed and non depressed subjects.

    Measured: up to 1 month

  3. Skin conductance reactivity reaction time

    it will be compared between depressed and non depressed subjects.

    Measured: up to 1 month

  4. hedonicity score of olfactory stimuli

    it will be compared between depressed and non depressed subjects.

    Measured: up to 1 month

Questions about this trial

What is this clinical trial studying?

A study testing olfactory assessment, image visualization and psychophysiological assessment in people with Depression, run by Centre Hospitalier Universitaire de Besancon at 1 site in France.

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 5 inclusion and 3 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: stopped early, as of the sponsor's last update on 5 Aug 2016. 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 France. 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 was stopped early (reason given: unavailable recording device and difficulty of patient inclusions). Results are not available in the source record.

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?

hedonicity score of visual stimuli (time frame: up to 1 month). The study lists 4 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 Aug 2016.
