The Center for the Adaptation and Implementation of Trust-based Relational Intervention (CAIT) is located in the Karyn Purvis Institute of Child Development at Texas Christian University. CAIT aims to provide national expertise in the training and implementation of Trust-based Relational Intervention (TBRI) and to support the continuum of care in child welfare and juvenile justice systems through specialized adaptations of TBRI. TBRI is an attachment-based, trauma-informed, whole-child approach to meeting the needs of children and youth who have experienced early adversity, toxic stress, and/or relational trauma. The TBRI model was developed at TCU to address the effects of trauma through three sets of practice principles: Connecting, Empowering, and Correcting. CAIT will address current gaps in trauma treatment, service delivery, and workforce development through (1) the development of an integrated trauma treatment model incorporating trauma assessment with current TBRI intervention practices; (2) the specialized adaptation of TBRI training and consultation for delivery in distinct service settings (child welfare & juvenile justice) and to be appropriate for different caregiver roles and diverse family structures (bio parents, resource parents, residential direct care staff); and (3) strategic collaboration to equip the child/youth-serving workforce through the NCTSN and through a wide established network of practitioners in the field.
