About this study

Official title: Basic Auditory Processing and Acoustico-verbal Hallucinations: a Pathophysiological Study

Schizophrenia is a severe psychiatric disorder that affects approximately 1% of the population worldwide. Although pathophysiology of this disease remains unclear, a growing interest is emerging for low-level sensory function, acknowledging that deficits in early stages of sensory processing are related to higher-order cognitive disturbances in schizophrenia. In the field of auditory processing, symptoms as auditory-hallucinations were found correlated with disabilities to discriminate psychoacoustic parameters of sounds.

Read the detailed description

Outcomes: Our main hypothesis is that Auditory Hallucinations Rating Scale (AHRS) scores are correlated with the percentage of wrong answers in a Tone-Matching Task test. The main objective is to assess this correlation. Our other objectives are to assess correlation between AHRS as well as other symptoms scales and psychoacoustic tests assessing intensity, length discrimination of non-verbal tones and self-monitoring abilities. Impact of therapeutic procedures (neuromodulation, psychotherapy) conducted independently of our study on these psychoacoustic tests will also be assessed.

Methods: 30 subjects with schizophrenia will be included. Clinical and psychoacoustic measures will be carried out at J-0. In the case of patients receiving therapeutic procedures independently of our study, new clinical and psychoacoustic measures will be carried out at J+7 and J+30.

What participants receive

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

  • Clinical and psychoacoustic measuresOther

    Our study focuses on psychoacoustic tests, specialist care protocols (psychotherapy, neuromodulation ...) being made independently of our study, as part of medical activity of Cerletti care unit or differentiated protocols. Thus, our study shows no individual benefit for the patient. However, a better understanding of the neurophysiological mechanisms underlying auditory hallucinatory phenomenon could allow a better management of these patients in the near future

What is being measured

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

  1. percentage error in discrimination test psychoacoustic Tone Matching Task

    Our main hypothesis is that Auditory Hallucinations Rating Scale (AHRS) scores are correlated with the percentage of wrong answers in a Tone-Matching Task test.

    Measured: immediately after treatment

Secondary outcomes (1)
  1. Score the item hallucinations of psychometric ( positive and negative syndrome ) scale

    Measured: immediately after treatment

Questions about this trial

What is this clinical trial studying?

A study testing Clinical and psychoacoustic measures in people with Schizophrenia, run by Hôpital le Vinatier 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 6 inclusion and 7 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 15 Aug 2022. 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 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?

percentage error in discrimination test psychoacoustic Tone Matching Task (time frame: immediately after treatment). 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 15 Aug 2022.
