“…Given the importance of developing treatments that are durable, recent translational research on the durability of common interventions for problem behavior has generated some troubling findings. Despite their widespread use (Petscher, Rey, & Bailey, 2009;Tiger, Hanley, & Bruzek, 2008) and robust efficacy while in effect (Greer, Fisher, Saini, Owen, & Jones, 2016;Hagopian, Fisher, Sullivan, Acquisto, & LeBlanc, 1998;Kurtz, Boelter, Jarmolowicz, Chin, & Hagopian, 2011;Petscher et al, 2009;Rooker, Jessel, Kurtz, & Hagopian, 2013), differential-reinforcementbased interventions for socially reinforced problem behavior are prone to relapse when differential reinforcement is suspended (Fisher et al, 2019;Fisher, Greer, Fuhrman, Saini, & Simmons, 2018;Fuhrman, Fisher, & Greer, 2016;Harding, Wacker, Berg, Lee, & Dolezal, 2009;Lichtblau, Greer, & Fisher, under review;Mace et al, 2010;Nevin et al, 2016;Volkert, Lerman, Call, & Trosclair-Lasserre, 2009;Wacker et al, 2011). These increases in problem behavior with the suspension of differential reinforcement are examples of resurgence.…”
