Pearson correlation coefficients if variables were normally distributed and Spearman (ρ) if not; level of significance (2-sided): **p<0.01, *p<0.05; CA, cardioceptive accuracy according to the Schandry paradigm and the Whitehead paradigm (d′); CDS, severity of depersonalization; CDS-ABE, severity of anomalous body experiences according to the CDS; BDI-II, severity of depression according to the Beck Depression Inventory second version; STAI, severity of trait anxiety according to the State-Trait Anxiety Inventory (trait version); KEKS, short body perception questionnaire; sample comprises DPD patients (n = 24) and healthy controls (HC) (n = 26); missing values HC/DPD: CA Schandry 1/0, CA Whitehead 3/2; HR 1/0; STAI 1/0; KEKS 1/0.
