Abstract

Background: Patients suffering from dissociative disorders (DD) are characterized by an avoidance of aversive stimuli. Clinical experience has shown that DD patients typically avoid the confrontation with their own faces in a mirror (CFM).Objective: To investigate potential CFM-associated self-reported and psychophysiological stress reactions of DD patients, which most likely inform on the still unknown pathophysiology of dysfunctional self-perception in DD.Method: Eighteen DD patients and 18 healthy controls (HCs) underwent CFM. They were assessed for CFM-induced subjective self-reported stress, acute dissociative symptoms and sympathetic and parasympathetic drive using impedance cardiography.Results: DD patients experienced more subjective stress and acute dissociation than HCs upon CFM. Their psychological stress response did not activate the sympathetic and parasympathetic nervous system.Conclusions: In DD patients, CFM constitutes serious self-reported stress and is associated with a blunted autonomic reactivity. Therapeutic approaches promoting self-perception and self-compassion, in particular by using CFM, might serve as goal-oriented diagnostic and therapeutic tools in DD.

  • The remaining studies reported no significant change in heart rate to mirror confrontation, white noise, or fear-potentiated startle.

    “The remaining studies reported no significant change in HR to mirror confrontation (Schäflein et al., 2018), white noise (Schalinski et al., 2013), or fear-potentiated startle (Seligowski et al., 2019).”

    For the mirror-confrontation citation, Table 4 (Results, “Sympathetic and parasympathetic tone during CFM assessed by impedance cardiography”) shows no significant change in heart period when participants moved from relaxation to mirror confrontation. But the Discussion (“Psychophysiology”) reports one significant within-patient change during mirror confrontation: heart rate dropped when the accompanying cognition changed from negative to positive. The unqualified claim of no significant heart-rate change therefore overstates the result; white noise and startle are attributed to other sources. (LLM, conf=0.87)

  • None of the other studies found correlations between heart rate variability and trait dissociation after exposure to trauma-related material or general stress stimuli.

    “None of the other studies found correlations between HRV and trait dissociation after exposure to trauma related material (Hauschildt et al., 2011) or general stress stimuli (Powers et al., 2021; Schäflein et al., 2018).”

    The Methods (Instruments and Data analysis; page unavailable) say the study measured trait dissociation with the Dissociative Experiences Scale and HRV with RMSSD, but describe mixed-model comparisons rather than correlations between them. The Results (Sympathetic and parasympathetic tone during CFM; page unavailable) report HRV changes during mirror-confrontation, not whether HRV correlated with trait dissociation. I found no reported test of the claimed correlation. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
