Mentalization-Based Treatment for young people at clinical high risk for psychosis

Mentalization Based Treatment (MBT) in Help Seeking Youths With a Clinical High-Risk Condition for Psychosis (CHR-P): a Randomized Controlled Trial

Not applicable Interventional Centre Hospitalier Universitaire Vaudois · NCT07093671

This project will test whether adding Mentalization-Based Treatment to usual need-based clinical care helps young people (ages 14–30) at high risk for psychosis reduce symptoms and avoid developing full psychosis.

What this trial studies

The trial compares Mentalization-Based Treatment (MBT) combined with need-based clinical interventions (NBCI) versus NBCI alone in help-seeking youths meeting SIPS criteria for a clinical high-risk state for psychosis. Outcomes include a three-level diagnostic status (transition to psychosis, CHR-P status quo, remission from CHR-P) and measures of psychotic symptom severity at end of treatment and at follow-up. Participants aged 14–30 without a prior psychotic disorder and able to provide consent (or with parental consent for minors) will be enrolled, with exclusions for intellectual disability (IQ <70), primary substance-induced symptoms, major language barriers, or guardianship. The study is conducted at CHUV in Lausanne and uses standardized clinical interviews and symptom scales to track diagnostic and symptomatic change over time.

Who should consider this trial

Good fit: Ideal candidates are young people aged 14–30 who meet SIPS criteria for CHR-P, have no prior psychotic disorder, can consent (or have parental consent), and do not have severe intellectual disability or primary substance-induced psychotic symptoms.

Not a fit: Patients with an established psychotic disorder, severe intellectual disability (IQ <70), psychotic symptoms primarily due to substance misuse, major language barriers, or who are under guardianship are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, adding MBT could reduce psychotic symptoms and lower the risk of progression to full psychosis, improving clinical and functional outcomes for at-risk youth.

How similar studies have performed: MBT has demonstrated benefits in personality disorders and there is emerging, limited evidence for psychotherapeutic approaches in early psychosis, but MBT specifically for CHR-P is relatively novel with limited direct evidence.
