Economic evaluation of three forms of early intervention for young people with borderline personality disorder: a within-trial cost-utility analysis from the MOBY clinical trial

Abstract

Borderline personality disorder (BPD) is a severe mental disorder that begins in adolescence and emerging adulthood. This study evaluated the comparative cost-effectiveness of three forms of early intervention, each with differing levels of treatment complexity, for young people with recently-diagnosed BPD.
