ABSTRACT
In this section, we consider the collaborative family therapy model of the Houston Galveston Institute (HGI) and the reflecting team model, both grouped as collaborative models. The work of the Houston Galveston Institute goes back to the development of multiple impact therapy (MIT) at the University of Texas Medical Branch in Galveston, Texas (MacGregor et al., 1964). Harry Goolishian was involved in the creation of this influential early model and was soon joined by Harlene Anderson. MIT involved every member of the family being interviewed by his or her own therapist, with all voices coming together, therapists and family members alike, at the end of the day (MacGregor et al., 1964). This respect for individual voices influenced Goolishian, Anderson, George Pulliam, and other colleagues of what later became the Galveston Family Institute and is now the Houston Galveston Institute (https://www.talkhgi.com" xmlns:xlink="https://www.w3.org/1999/xlink">www.talkhgi.com). In these early days, the team was also influenced by the brief therapy approaches, in particular MRI (Chapter 29), but as time went on, Goolishian and Anderson in particular began to deemphasize intervention and put more emphasis on joining with the reality of clients (Anderson, 2011). By the 1990s, collaborative therapy was clearly identified as a distinct model (Anderson, 1997). Lynn Hoffman also used the term to describe her model of therapy (Hoffman, 1993).
