Design outcomes

Primary

Measure	Time frame
General Purpose: To investigate whether emotion inductions with different levels of arousal affect body perception differently in patients with low and high dissociative symptoms or healthy control subjects. Primary Outcomes: - Checking the success of the emotion inductions: during each trial, heart rate and skin conductance will be measured to check physiological arousal. These physiological parameters will be compared to the last 15 seconds of a 1-minute resting baseline before each trial. In addition, mood (valence and arousal) will be measured with the Self-Assessment Manikin (SAM) following each trial and after a 3-minute habituation pariod at baseline. - Rubber hand illusion strength: following each trial of the rubber hand illusion, the subjective strength of the rubber hand illusion is assessed by a questionnaire by Longo et al. (2008) (mean of all items). In addition, a proprioceptive assessment of the position of the left finger will be made before and after each trial and subtracted from each other to determine the proprioceptive drift. - Degree of acute dissociation: after the 3-minute habituation period, as well as after each rubber-hand illusion trial, acute dissociation will be measured using the DSS-4 (Stiglmayr et al., 2009). - Interoceptive abilities: at the beginning of the experiment, a heartbeat tracking task (Garfinkel et al., 2015) is completed, in which participants are asked to count their own heartbeat at 6 fixed time intervals, between 25 and 50 seconds, while simultaneously recording the ECG. This results in the following outcomes: Interoceptive Accuracy = Agreement between measured and counted heartbeats; Interoceptive Sensibility = The indication of how confident the participants are with their own counting (measured from 0 - 100%); Interoceptive Awareness = The correlation between accuracy and confidence. The following hypotheses will be investigated: 1. We hypothesize that patients with high dissociative symptoms have lower interoc	—

Secondary

Measure	Time frame
In addition to the above-mentioned measures, diagnostic interviews (MINI, borderline part of SCID-PD), as well as some questionnaires (HDI, CDS, BAI, BDI, DERS, PAQ, CASES-G) will be completed on a separate date before the main measurement. These are primarily for diagnostic purposes and to verify inclusion criteria. In addition, the PAQ, DERS, and CASES-G questionnaires will be examined in more detail in an additional analysis.	—
