<h3>About the Shutdown Dissociation Scale (SHUT-D)</h3>
<div class="info-box">
The <strong>Shutdown Dissociation Scale (SHUT-D)</strong> is a self-report questionnaire designed to measure shutdown dissociative responses that may occur during overwhelming stress, fear, trauma, or extreme emotional activation.
</div>
<div class="info-box">
The SHUT-D was developed by <strong>Inga Schalinski</strong>, <strong>Thomas Elbert</strong>, <strong>Maggie Schauer</strong>, and colleagues as part of trauma and dissociation research focused on defensive survival responses and psychophysiological shutdown reactions.
</div>
<div class="info-box">
The questionnaire evaluates dissociative shutdown experiences including fainting, motor inhibition, numbness, sensory shutdown, autonomic distress, depersonalization, paralysis-like experiences, and speech inhibition.
</div>
<div class="info-box">
Research studies have demonstrated strong reliability and validity for the SHUT-D across trauma psychology, PTSD research, dissociation studies, psychophysiology, psychiatry, and stress-response research.

<h4>Psychological Domains Measured</h4>
<div class="domain-grid">
<div class="domain-card">
<strong>Fainting and Collapse</strong>
<span>Measures collapse responses, fainting episodes, passing out, and shutdown-related loss of physical stability.</span>
</div>
<div class="domain-card">
<strong>Sensory Shutdown</strong>
<span>Measures sensory disruptions including temporary blindness, hearing disturbances, sensory disconnection, and altered perception.</span>
</div>
<div class="domain-card">
<strong>Physical Numbing</strong>
<span>Measures numbness, loss of bodily sensation, reduced pain sensitivity, and altered physical awareness.</span>
</div>
<div class="domain-card">
<strong>Motor Inhibition</strong>
<span>Measures paralysis-like reactions, physical freezing, bodily heaviness, immobility, and shutdown-related motor inhibition.</span>
</div>
<div class="domain-card">
<strong>Autonomic Distress</strong>
<span>Measures nausea, sweating, dizziness, weakness, autonomic activation, and physiological stress reactions.</span>
</div>
<div class="domain-card">
<strong>Depersonalization</strong>
<span>Measures out-of-body experiences, altered self-awareness, and feelings of detachment from oneself or one’s body.</span>
</div>
<div class="domain-card">
<strong>Speech Inhibition</strong>
<span>Measures temporary inability to speak, whispering, speech shutdown, and difficulty producing speech under stress.</span>
</div></div>
<div class="notice-box">
The SHUT-D is commonly used in trauma psychology, PTSD research, dissociation studies, psychiatry, psychophysiology, and stress-response research. The questionnaire is intended as a screening instrument and should not be used as a standalone diagnostic tool.
