Abstract

Following the publication of our article [1], we have become aware of one error in the exclusion criteria, inconsistencies in Figs. 1 and 2, and a typo in the reference list. Exclusion criterion # 10 is incorrect. Correction: (10) participating regularly in 60 min of moderate intensity physical exercise per week, divided across 2 or more bouts of physical exercise. The physical exercise exclusion criteria are omitted from Fig. 1 in the original publication. The correct version of Fig. 1 is included here. In Fig. 2, the interim testing contains three tests which are not conducted at this point of measure. These are The Five-Minute Pyramid test, The Biering-Sørensen Test, and the Dumbbell Arm Press Test. The correct version of Fig. 2 is included here. We have discovered a typo in the reference for the Expectancy / Credibility Scale. The correct reference is: Borkovec, T. D. and S. D. Nau (1972). “Credibility of analogue therapy rationales.” Journal of Behavior Therapy and Experimental Psychiatry 3(4): 257–260.
