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

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

About This Trial

The primary objective of this study is to evaluate the efficacy of Mentalization-Based Treatment (MBT) combined with Need-Based Clinical Interventions (NBCI) compared to NBCI alone, on CHR-P diagnostic statuses and symptom expression (Hypothesis 1). Specifically, the investigator will assess diagnostic outcomes using a 3-level variable: transition to psychosis, CHR-P status quo, and remission out of CHR-P, as well as CHR-P symptom expression. The investigator hypothesize that: (1a) the experimental treatment (MBT + NBCI) will have a significant effect on diagnostic status (i.e. transition to psychosis) at the end of treatment and follow-up; (1b) the experimental treatment (MBT + NBCI) will significantly reduce the severity of psychotic symptoms at the end of treatment and follow-up.

MBT + NBCI

The MBT for CHR-P intervention consists of 24 weekly individual psychotherapy sessions, supplemented by monthly mentalization-based family therapy sessions. Both patient and family sessions will last 50 minutes. These psychotherapeutic sessions will complement those received though NBCI by strengthening mentalizing abilities aiming to reduce or prevent detrimental outcomes, by prohibiting or restricting some usual techniques in NBCI treatment (e.g., interpretation, cognitive challenge and Socratic dialogue) and by emphasizing certain techniques (e.g., empathic validation, active management of emotional arousal) which are only sporadically and irregularly used during NBCI treatment. Overall, the program is designed to improve patients' capacity to understand their own and others' mental states and, within interpersonal settings, how these patterns contribute to conflict and psychological distress.
