In their work they have integrated their complementary cognitive and experiential treatment approaches with social learning and developmental psychology theory to develop a group treatment model for Schema Therapy (ST). Influenced by their 30+ years of clinical experience and by the work of Jeff Young, they adapted ST interventions and limited reparenting to a group model and developed uniquely group interventions to accomplish ST goals (Farrell & Shaw, 1994). They first established the group model for outpatients in a specialty clinic for BPD at the IUSM outpatient clinic. This program was awarded an Indiana Governor’s Showcase Award in Mental Health and a NIMH grant. They went on to develop an inpatient ST program that combines individual and group modalities and directed a dedicated BPD unit for ten years at a university affiliated psychiatric hospital in Indianapolis. They evaluated their model of Group Schema Therapy in a randomized controlled trial for outpatients (Farrell, Shaw & Webber, 2009- funded by NIMH)) and in two inpatient pilot study (Reiss, Lieb, Arntz, Shaw & Farrell, in press). Both studies demonstrated strong positive effects on BPD symptoms and global function as well as high recovery rates. Currently, they are the clinical trainers and treatment supervisors of a randomized controlled trial with 14 sites in five countries that will further test their model of Group ST. Joan is co-PI for the multi-site study with Arnoud Arntz, Ph.D. Also with Arntz, Reiss and Fretwell, they are further evaluating the intensive GST model in Day Hospital and inpatient settings.
