Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After the second baseline BPDSI assessment, patients will be randomized over three conditions: Schema Therapy (individual focus: weekly individual and group sessions) or schema therapy with a group focus in which the partcipants receive group treatment twice a week(GST) in blocks of by the central research assistant (at the main Netherlands site) using a computerized randomization program. The order in which the formats of GST will be delivered is randomized over sites, so that order of group format type is balanced over sites, controlling for therapist learning and time effects.

It will be explained to patients why the main assessor needs to be blind and they will be asked not to talk about the type of treatment they receive. After each assessment, blindness will be assessed by asking the assessor to guess the patient’s condition. The assessment of healthcare costs is done by a second unblinded assessor due to the information needed.
