“…While much of the evidence of efficacy of those approaches derives from tightly-controlled research trials (e.g., Fairburn, Cooper, Doll, O'Connor, Bohn, Hawker, Wales, & Palmer, 2009;Fairburn, Cooper, Doll, O'Connor, Palmer, & Dalle Grave, 2013;Poulsen, Lunn, Daniel, Folke, Mathieson, Katznelson, & Fairburn, 2014;Zipfel, Wild, Gro , Friederich, Teufel, Schelberg, Giel, de Zwaan, Dinkel, Herpertz, Burgmer, Löwe, Tagay, von Wietersheim, Zeeck, Schade-Brittinger, Schauenburg, & Herzog, 2014), recent studies have demonstrated its effectiveness in routine clinical settings (e.g., Byrne, Fursland, Allen, & Watson, 2011;Waller, Gray, Hinrichsen, Mountford, Lawson, & Patient, 2014). However, such effectiveness depends on the use of the core techniques developed in efficacy studies, and particularly the use of manual-based methods (e.g., Addis & Waltz, 2002;Cukrowicz, Timmons, Sawyer, Caron, Gummelt, & Joiner, 2011).…”
