Outcomes

Primary Outcomes

CAARMS (Comprehensive assessment of at-risk mental states) score.

The test will determine the mental state of the patient : * "Not at risk of psychosis" * "At risk of psychosis" * "Psychosis threshold exceeded" It is organized into 7 clinical dimensions: 1) positive symptoms 2) cognitive changes: attention / concentration 3) emotional disturbance 4) negative symptoms 5) behavioral change 6) physical and motor changes 7) general psychopathology. Each category is scored between 0 and 6 depending on the level of intensity, frequency and duration of each symptom. In order to determine if a subject meets the UHR criteria for CAARMS, only the first category (positive symptoms) and its four subscales are used according to a scoring algorithm.

Time frame: 5 years

Secondary Outcomes

CAARMS sub-assemblies

If the patient is classified at risk of psychosis, the test will classify this risk into one of the three following categories : trait and state risk factor group, APS (attenuated psychotic symptoms) group, BLIPS (Brief, Limited or Intermittent Psychotic Symptoms) group.

Time frame: 5 years
