O ur rupture research program can be traced back to the Clarke Institute of Psychiatry in Toronto, where Jeremy Safran directed a team of clinical researchers in the late 1980s that included Lisa Wallner Samstag and Chris Muran. Since 1990, it has been situated at Mount Sinai Beth Israel (MSBI) in New York under the directorship of Chris Muran (principal investigator) with Jeremy Safran (senior consultant), Lisa Wallner Samstag, and subsequently Catherine Eubanks (joining in 2007) as primary collaborators and coinvestigators, and with support from the MSBI Department of Psychiatry (chair, Arnold Winston, until 2015) and the National Institute of Mental Health.As evidence of what we have described as a "second generation" of alliance research, there has been a burgeoning of empirical literature on ruptures and their repair (Muran, 2019), including meta-analytic evidence that rupture repair is associated with good treatment outcome (Eubanks et al., 2018). When we look back at the history of our rupture research program, it becomes clear that to a great extent our study of ruptures has always been, at its heart, the study of training therapists to navigate ruptures-specifically, alliance-focused training (AFT). In this chapter, we describe AFT and present the existing empirical support for this approach to training. We also illustrate AFT with data from an AFT session, as well as propose promising future directions.
