“…Although widely practiced throughout the world, NT remains underresearched (Busch, 2011;Chenail, DeVicentis, Kiviat, & Somers, 2012;Etchison & Kleist, 2000). Some qualitative process research studies (Matos, Santos, Gonçalves, & Martins, 2009;Moreira, Beutler, & Gonçalves, 2008) and several case studies (Betchley & Falconer, 2002;Cashin, 2008;da Costa, Nelson, Rudes, & Guterman, 2007;Draucker, 1998;Kropf & Tandy, 1998;Nylund, 2002;Palgi & Ben-Ezra, 2010;Rothschild, Brownlee, & Gallant, 2000;Young, 2008) suggest positive outcomes for a wide range of problems and disorders. However, only one of these qualitative studies (Kropf & Tandy, 1998) has addressed the effectiveness of NT for depression, and none have done so in a controlled clinical trial.…”
