... However, it is noted here because of the relatively consistent findings that across such a variety of methods, purposes, and measures, researchers are reporting positive findings. Each of the references noted here describes some tangible positive outcomes from coaching: ■ research based on self-report from participants and their managers using diverse samples and data-collection methodologies (e.g., Bush, 2005; B. L. Davis & Petchenik, 1998;Kombarakaran, Yang, Baker, & Fernandes, 2008;Leedham, 2005;Seamons, 2006;Thompson, 1986;Wasylyshyn, 2003;Wasylyshyn, Gronsky, & Haas, 2006); ■ individual case studies (e.g., Blattner, 2005;Diedrich, 1996;Hunt, 2003;Kiel, Rimmer, Williams, & Doyle, 1996;Kralj, 2001;Libri & Kemp, 2006;Natale & Diamante, 2005;Orenstein, 2006;Peterson, 1996;Peterson & Millier, 2005;Schnell, 2005;Tobias, 1996;Wasylyshyn, 2005;Winum, 2005); ■ organizational case studies, dozens of which are described in books by Clutterbuck and Megginson (2005), Hunt and Weintraub (2007), and Jarvis et al. (2006); ■ surveys of organizational purchasers of coaching (Dagley, 2006;Leedham, 2005;McDermott, Levenson, & Newton, 2007); ■ evaluations of ROI (e.g., Anderson, 2001;Corporate Leadership Council, 2004;Holt & Peterson, 2006;McGovern et al., 2001;Parker-Wilkins, 2006;Phillips, 2007;Schlosser, Steinbrenner, Kumata, & Hunt, 2006); ■ a small but growing number of quasi-experimental and other carefully designed research studies (e.g., Evers, Brouwers, & Tomic, 2006;Finn, 2007;Finn, Mason, & Griffin, 2006;Grant, Curtayne, & Burton, 2009;Offermanns, 2004 [as reported in Greif, 2007]; Peterson, 1993b;Smither et al., 2003;Steinmetz, 2005 Levenson, 2009;MacKie, 2007;Passmore & Gibbes, 2007). ...
