About this study

Official title: Characterize the Behavioral Prodromes of Psychotic Disorders in Children With 22q11.2DS Aged From 4 to 13 Years Old

The study PremiCeS22 will investigate the prodromal signals at the onset of psychotic disorders of children with 22q11.2 deletion syndrome

Read the detailed description

22q11.2DS is one of the most common microdeletion syndromes (1 / 2000-1 / 4000 births) and one of the most robust genetic risk factors for schizophrenia (1 to 2% of cases). Reciprocally, approximately 30% of patients with 22q11.2DS will develop psychotic symptoms in adolescence or early adulthood. It is now well established that children and adults with 22q11.2DS have lower social skills than developing youth. These social dysfunctions could be partly underpinned by alterations in social cognitive processes, and could also be linked to the emergence of psychotic signs or even schizophrenia. However, to our knowledge, no study has investigated the existence of behavioral prodromal signs during the onset of psychotic signs in children with 22q11.2DS. In addition, the origin of social cognitive processes remains to this day little explored.

What participants receive

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

  • neuropsychological testing, questionnaires and experimental tasksBehavioural

    Neuropsychological testing (the Sky Search subtest from the Test of Everyday Attention for Children (TEA-Ch); the Overlapping lines task of Rey; auditory attention of NEPSY II battery); questionnaires completed by the children's legal representatives to assess behavior; experimental tasks evaluating gaze direction and facial expression recognition

What is being measured

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

  1. The Screen for child Anxiety Related Emotional Disorders (SCARED)

    Scale assessing behavioral prodromes or warning signs of hallucinations in psychotic disorders A psychometric study is then carried out on this questionnaire in order to validate it with parents of children carrying 22q11.2DS.

    Measured: Day 1

  2. facial expression recognition task

    Proportion of correct responses in experimental tasks evaluating gaze direction and facial expression recognition

    Measured: Day 1

Secondary outcomes (4)
  1. Sustained hearing attention test (Tea-Ch battery)

    Proportion of impaired scaled score at the Sky Search subtest from the Test of Everyday Attention for Children (TEA-Ch)

    Measured: Day 1

  2. Rey's Tangled Lines Test

    Proportion of impaired scaled score to study the degree of cognitive development in children

    Measured: Day 1

  3. NEPSY II battery

    Proportion of impaired scaled score at auditory attention of NEPSY II battery The NEPSY-II is a comprehensive neuropsychological battery for children ages 3-12. The test provides measures of sensor-motor, language, visuospatial processing, memory and learning, attention/executive functions, and social cognition.

    Measured: Day 1

  4. Mean reaction time

    Mean reaction time in neuropsychological testing and experimental tasks

    Measured: Day 1

The record says: looking for participants now, as of the sponsor's last update on 30 Jul 2025. 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?

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

Contact Caroline DEMILY, MD PH (0450915163 ext. +33, caroline.demily@ch-le-vinatier.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Screen for child Anxiety Related Emotional Disorders (SCARED) (time frame: Day 1). 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.
