- Brief summaryIn an international multicenter RCT two forms of group Schema Therapy for Borderline Personality Disorder will be compared to the usual treatment provided to these patients. Effectiveness, cost-effectivenss (with full economic analysis, incl cost-utility and cost-effectiveness), and stakeholders'opnions will be assessed. A secondary aim is to find out what format of group Schema Therapy is to be preferred: mainly group treatment, or the combination of group and individual treatment. the study will take place in at least 14 centers in the Netherlands, Germany, USA, UK, Sweden, Ireland and Australia. At each center min. 32 participants will be recruited, and randomized over the two forms of group Schema Therapy and treatment as usual. Experimental treatment will be provided for 2 years, and a last follow-up assessment will be done at year 3.
