“…Although a review of full treatments, as presented here, cannot establish the efficacy of specific therapeutic components (Chorpita, Becker, & Daleiden, 2007), this update will (a) evaluate mediators and moderators of treatment outcome, and (b) identify those specific treatment components or techniques that are most often present in protocols that have demonstrated empirical support. More specifically, in addition to presenting findings at the level of treatment families (consistent with the move away from discussing ''brand-name'' therapies; e.g., Chorpita et al, 2002Chorpita et al, , 2011Rogers & Vismara, 2008), this report also presents frequency profiles of the practice elements associated with the most efficacious treatments, as have previous reviews of the outcome literature for youth internalizing and externalizing problems (e.g., Borntrager, Chorpita, Higa-McMillan, Daleiden, & Starace, 2013;Brookman-Frazee, Haine, Baker-Ericzen, Zoffness, & Garland, 2010). Whereas the construct of treatment family serves to aggregate similar treatment protocols that employ common therapeutic elements (e.g., individual protocols that each involve self-monitoring, ANXIETY DISORDERS UPDATE developing coping statements, and associated behavioral exercises would be grouped together as one treatment family), the concept of practice element is intended to assist in identifying the specific ''clinical ingredients'' (e.g., Cognitive, Exposure, Relaxation; Chorpita, Daleiden, & PracticeWise, 2009, p. 7) of which each treatment protocol is comprised.…”
