“…They argued that there is no evidence that all SBs necessarily prevent disconfirmatory experiences, and that the incorporation of SB in exposure could facilitate treatment and may reduce drop-out and refusal. Recent research suggests that adding SB to exposure can indeed enhance treatment acceptability Levy, Senn, & Radomsky, 2014;Milosevic & Radomsky, 2013a), although other studies did not find differences in acceptability between exposure with SB (E þ SB) and without SB (E þ RP; see, for example, Deacon, Sy, Lickel, & Nelson, 2010;Milosevic & Radomsky, 2013b). Additionally, although several studies have shown unfavorable effects E þ SB compared to E þ RP (e.g., McManus, Sacadura, & Clark, 2008;Salkovskis, Clark, Hackmann, Wells, & Gelder, 1999), other studies suggest that SB is not always detrimental to the beneficial effects of exposure.…”
