French version of the Schizophrenia Proneness Instrument for children and adolescents (SPI-CY)

French Validation of Schizophrenia Proneness Instrument- Child Youth

Not applicable Interventional Centre Psychothérapique de Nancy · NCT06649552

This project will test the French SPI-CY to see if it reliably identifies French-speaking adolescents (ages 12–17) who are at high risk for developing psychosis.

What this trial studies

This multicenter work enrolls French-speaking adolescents aged 12 to 17 who are already identified as being at clinical high risk for psychosis and administers the SPI-CY interview, with audio recording of sessions. Investigators will examine the instrument's reliability and how well its scores agree with existing clinical measures such as CAARMS and clinical judgment. The goal is to produce psychometric data (e.g., internal consistency, interrater reliability, and predictive indicators) for the French version. The project is conducted at three French centers (Nancy, Lille, Saint-Egrève) using standard psychiatric diagnostic interview procedures.

Who should consider this trial

Good fit: Ideal candidates are French-speaking adolescents aged 12 to 17 years 11 months who are followed at one of the three participating centers for suspected clinical high risk of psychosis and who (and whose parent) consent to audio recording of the interview.

Not a fit: Patients outside the 12–17 age range, non–French speakers, those unwilling to be audio-recorded, pregnant individuals, or those deprived of liberty are unlikely to be eligible or to benefit from this protocol.

Why it matters

Potential benefit: If successful, a validated French SPI-CY could improve early detection of prodromal symptoms in adolescents, enabling earlier support and interventions to delay or prevent a first psychotic episode.

How similar studies have performed: The basic symptoms approach and the adult SPI-A have prior international validation and clinical use, while translations and validations of the SPI-CY are less widespread, making this French validation a necessary extension of earlier work.
