About this study

This project will use the collected clinical and biological information of high-risk groups, use embedded computer chips, and use big data background analysis system to comprehensively evaluate the risk of high-risk groups, and build a mental illness risk estimator completely relying on the sample data of Chinese population and with independent intellectual property rights.

The calculator function and the risk calculation standard verified by the model can obtain the risk degree of each patient's progress to psychosis in the next two years. This calculator will play an important role in the prevention and treatment of psychosis.

Read the detailed description

Severe mental disorders, mainly schizophrenia (SZ), affect 16 million Chinese population. At present, due to the lack of effective techniques and standards for early risk identification, the intervention opportunity for prevention and optimal efficacy is often missed.

In previous cohort studies , it has been found that this clinical high-risk(CHR) population can be effectively identified before its onset. Since 2011, the project team has been relying on the ShangHai At Risk for Psychosis Program, 300 CHRs were enrolled in the clinic through screening and diagnostic interview. The baseline clinical and event-related EEG indicators of this cohort were collected. The cohort was followed up for 2 years, with a follow-up completion rate of nearly 90%, it was found that the clinical outcome of high-risk groups was nearly one third, and the proportion of patients would be converted to schizophrenia within 2 years. This conversion rate is very consistent with the results of cohort studies of other large high-risk groups in the world. In view of this conversion ratio, many countries, such as the United States, have begun to use the baseline information to build prediction models, so as to form a psychiatric prediction tool.

After 5 years of accumulation, the project team has sufficient data to build a psychosis risk prediction model suitable for Chinese people, truly realize the goal of early diagnosis and treatment, and further support with the integration of key identification technologies and big data calculation.

What is being measured

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

  1. Conversion to psychosis

    It will be determined using the criteria for the Presence of Psychotic Symptoms from SIPS. Specifically, the conversion will be defined by the presence of level 6 positive symptoms (the rating "6" refers to severe and psychotic symptoms) identified as either dangerous, disorganised, or occurring at least one hour a day on average, over four days a week for at least 16 hours.

    Measured: 4 weeks

  2. Poor function

    It will be determined by GAF score. Specifically, poor function outcome is defined as the GAF score of less than 60 at the follow-up point.

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Clinical High-risk, run by Shanghai Mental Health Center at 1 site in China.

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 9 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 12 Aug 2020. 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 China. 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?

Conversion to psychosis (time frame: 4 weeks). 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 12 Aug 2020.
