Summary
This study found a strong positive correlation between Spiegel's Eye-Roll Sign (ERS) and the Perceptual Alteration Scale (PAS), suggesting ERS may be a reliable biological marker for dissociation capacity.
Area of Science:
- Psychiatry
- Neuroscience
- Psychology
Background:
- Dissociative disorders are increasingly recognized as pervasive.
- A reliable measurement for dissociation capacity is needed.
- The Perceptual Alteration Scale (PAS) measures dissociation behaviorally.
Purpose of the Study:
- To compare the Perceptual Alteration Scale (PAS) with Spiegel's Eye-Roll Sign (ERS).
- To assess the validity of ERS as a biological marker for dissociation capacity.
Main Methods:
- 107 subjects underwent PAS and ERS measurements.
- Pearson Correlation Coefficients were computed.
- PAS scores and ERS measurements were analyzed.
Main Results:
- The mean PAS score was 155.
- The mean ERS score was 3.7.
- A significant positive correlation (r=0.55, p<0.0001) was found between ERS and PAS.
Conclusions:
- Spiegel's Eye-Roll Sign (ERS) is highly correlated with the Perceptual Alteration Scale (PAS).
- ERS shows potential as a biological marker for dissociation capacity across the dissociative continuum.
- Further research should correlate ERS with other dissociation measures like the DES.
