Note. Values are M (SD), min-max range, weighted for missing responses. ${\mathrm{\eta }}_p^2$= partial eta Squared (values greater than .14 indicate large effect size). Post hoc contrasts were carried out using Tukey’s multiple comparisons correction. BSI = Brief Symptom Inventory; DES-II = Dissociative Experiences Scale–II; DES-IV = Differential Emotions Scale.
