Table 2 Overview of tests of neurocognitive function and body image distortion applied during timepoint 1 (T1) and timepoint 2 (T2). The Set-shifting battery is based on Wolff et al. [125]; the Value-based- decision making battery (VBDM) based on Pooseh et al. [90]. The Somatomap 3D is conducted according to Ralph-Nearman et al. [94]. The Rey Osterrieth Complex Figure Test [78] was used
