However, it remains unclear whether atypical responsiveness to suggestion is similarly present in depersonalization-derealization disorder (DDD). 55 DDD patients and 36 healthy controls completed a standardised behavioural measure of direct verbal suggestibility that includes a correction for compliant responding (BSS-C), and psychometric measures of depersonalization-derealization (CDS), mindfulness (FFMQ), imagery vividness (VVIQ), and anxiety (GAD-7). Relative to controls, patients did not exhibit elevated suggestibility (g = 0.26, BF10 =.11) but displayed significantly lower mindfulness (g = 1.38), and imagery vividness (g = 0.63), and significantly greater anxiety (g = 1.39). Although suggestibility did not correlate with severity of depersonalization-derealization symptoms in controls, r = -.03 [95% CI: -.36,.30], there was a weak tendency for a positive association in patients, r =.25, [95% CI: -.03,.48]. Exploratory analyses revealed that patients with more severe anomalous bodily experiences were also more responsive to suggestion, an effect not seen in controls. This study demonstrates that DDD is not characterized by elevated responsiveness to direct verbal suggestions. These results have implications for the aetiology and treatment of this condition, as well as its classification as a dissociative disorder in psychiatric nosology. date: 2022-09-01 date_type: published publisher: Elsevier BV official_url: https://doi.org/10.1016/j.psychres.2022.114730 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1968279 doi: 10.1016/j.psychres.2022.114730 lyricists_name: David, Anthony lyricists_id: ADDAV87 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Psychiatry Research volume: 315 article_number: 114730 citation: Millman, LSM; Hunter, ECM; David, AS; Orgs, G; Terhune, DB; (2022) Assessing responsiveness to direct verbal suggestions in depersonalization-derealization disorder.
