“…The effect size for such interventions is impressive (e.g., Haynes et al, 2008;Norton & Price, 2007;Olatunji, Cisler, & Deacon, 2010;Opriş et al, 2012). There are numerous examples of other multicomponent interventions developed without a preintervention functional assessment with documented effectiveness for problems including, but not limited to, depressive disorders (e.g., Cuijpers, Andersson, Donker, & van Straten, 2011;Hans & Hiller, 2013), pain management (e.g., Lunde, Nordhus, & Pallesen, 2009;Veehof, Oskam, Schreurs, & Bohlmeijer, 2011), and childhood conduct problems (Lee, Niew, Yang, Chen, & Lin, 2012;Maughan, Christiansen, Jenson, Olympia, & Clark, 2005). More often than not, these evidencebased interventions have an accompanying implementation manual.…”
