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.

Fig. 1
figure1

Study design. Visual presentation of the study design, including sample, assessments, and interventions. GAD, generalised anxiety disorder; CBT, cognitive behaviour therapy

Fig. 2

Standard protocol items: recommendation for interventional trials (SPIRIT) figure. Schedule of enrolment, interventions and assessments. Overview of the measures applied in the study. CBT, cognitive behaviour therapy; ADIS-IV, Anxiety Disorders Interview Schedule for DSM-IV; M.I.N.I., Mini International Neuropsychiatric Interview; PSWQ, Penn State Worry Questionnaire; GAD-7, Generalized Anxiety Disorder 7-item scale; IPAQ, International Physical Activity Questionnaire; HRV, heart rate variability; BDNF, brain-derived neurotropic factor; WASI, Wechsler Abbreviated Scale of Intelligence; WAIS-IV, Wechsler Adult Intelligence Scale – Fourth Edition; D-KEFS, Delis–Kaplan Executive Function System; TMT, Trail-Making Test; VF, Verbal Fluency; CWIT, Color Word Interference Test

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.
