“…Although there is some variation between HRT and CBIT due to the incorporation of specific therapeutic components (e.g., relaxation training, functional analysis), both include the core therapeutic components of awareness training and competing response training (Peterson, 2007; Woods, Miltenberger, & Lumley, 1996). Randomized controlled trials consistently demonstrate the acceptability, efficacy, and safety of these behavioral interventions (Deckersbach, Rauch, Buhlmann, & Wilhelm, 2006; Piacentini et al, 2010; Wilhelm et al, 2003; Wilhelm et al, 2012), with a recent meta-analysis identifying moderate-to-large treatment effects (McGuire, Piacentini, et al, 2014). Indeed, treatment guidelines recommend behavior therapy as a first-line intervention for youths with CTDs (Murphy, Lewin, Storch, & Stock, 2013; Steeves et al, 2012; Verdellen, van de Griendt, Hartmann, & Murphy, 2011).…”
