“…Of the 54 papers that underwent a full-text review, the five most common reasons for exclusion were that the study: (i) featured a single-dose adapted LKM or CM experimental test rather than training as part of a program of psychotherapy (e.g., Barnhofer, Chittka, Nightingale, Visser, & Crane, 2010;Crane, Jandric, Barnhofer, & Williams, 2010;Engström, & Söderfeldt, 2010;Feldman, Greeson, & Senville, 2010;Hutcherson et al, 2008;Lee et al, 2012;Logie & Frewen, 2014), (ii) utilized an intervention integrating lovingkindness and/or compassion techniques that was not based on meditation (e.g., Gilbert & Procter, 2006;Leiberg et al, 2011;Mayhew & Gilbert, 2008;Oman, Thoresen, & Hedberg, 2010), (iii) was not designed to explicitly assess changes in the symptom severity of DSM-IV-TR Axis I disorders in clinical samples and/or known concomitants thereof in subclinical/healthy samples (e.g., Condon, Desbordes, Miller, & DeSteno, 2013;Hunsinger, Livingston, & Isbell, 2013;Mascaro, Rilling, Negi, & Raison, 2013b;May et al, 2011;Weng et al, 2013), (iv) was primarily based on self-compassion techniques (e.g., Albertson, Neff, & Dill-Shackleford, 2014;Neff & Germer, 2013;Shapira, & Mongraina, 2010), or (v) was not published in a peer-reviewed journal (e.g., Humphrey, 1999;Kleinman, 2011;Law, 2012;Templeton, 2007;Weibel, 2008).…”
