Trial summary

Source-monitoring is a cognitive process that refers to the ability to remember the source of an information. Some studies have showed source-monitoring deficits in patients with schizophrenia as well as in individuals at ultra-high risk for psychosis (UHR) and in first-episode psychosis patients (FEP).

About this study

Official title: Source-monitoring Processes and Risk for Psychosis

Source-monitoring is a cognitive process that refers to the ability to remember the source of an information. Some studies have showed source-monitoring deficits in patients with schizophrenia as well as in individuals at ultra-high risk for psychosis (UHR) and in first-episode psychosis patients (FEP). Source-monitoring deficits have thus been proposed as a potential early risk factor for psychosis. However, further studies are needed to better characterize this deficit.

The aim of this project is to investigate source-monitoring performances in UHR, FEP patients and healthy controls (HC) and to characterize these deficits in terms of brain anatomy, basic auditory processes and social functioning.

Read the detailed description

Ninety participants will be included in the study: 30 UHR, 30 FEP and 30 healthy controls. All the participants will complete a standardized source-monitoring task, an MRI acquisition (3D-T1 anatomical scan), a tone-matching task as well as a socio-demographic and clinical evaluation including an assessment of the social functioning.

What is being measured

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

  1. Source-monitoring performances

    Scores obtained at a source-monitoring task (Brunelin et al., 2006)

    Measured: one day

Secondary outcomes (6)
  1. Confidence in source-monitoring judgements

    Confidence in source-monitoring judgements will be measured using a visual analogue scale (0-100)

    Measured: one day

  2. Grey matter volume

    Grey matter volume will be assessed with a structural MRI scan (3D-T1) followed by morphometry analyses.

    Measured: one day

  3. Brain gyrification

    Brain gyrification will be assessed with a structural MRI scan (3D-T1) followed by gyrification analyses.

    Measured: one day

  4. Basic auditory performances

    scores at the Tone Matching Task (Strous et al., 1995)

    Measured: one day

  5. Working memory performances

    scores at a working memory task (Barrouillet et al., 2004)

    Measured: one day

  6. Social functioning

    score at the "personal and social performance scale" (0-100)

    Measured: one day

Questions about this trial

What is this clinical trial studying?

A study testing Cognitive tests and neuroimaging in people with Psychosis, run by Hôpital le Vinatier at 2 sites 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 8 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 24 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Lydie sartelet (0437915531 ext. +33, lydie.sartelet@ch-le-vinatier.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Source-monitoring performances (time frame: one day). 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 24 Mar 2022.
