Mechanistic Interventions and Neuroscience of Dissociation
Emory University
350 participants

INTERVENTIONAL
Conditions
Summary
The purpose of this study is to test the neurophysiological mechanisms of an intervention to reduce symptoms of dissociation in traumatized people. The intervention will be tested in dissociative traumatized people at two sites: Emory University and University of Pittsburgh. The researchers are interested in whether neural networks associated with attentional control and interoceptive awareness can be enhanced in this population. The researchers propose to evaluate whether different body-focused and non-body focused interventions can change these mechanisms.
Eligibility
Inclusion Criteria3
- experience of at least one Diagnostic and Statistical Manual of Mental Disorders (DSM-5) Criterion A trauma (assessed using the Life Events Checklist)
- a score of 7 or higher on the Multiscale Dissociation Inventory (MDI) depersonalization subscale
- willingness to participate in the study
Exclusion Criteria3
- actively psychotic and cognitively compromised individuals (assessed using the Moderate-severe cognitive impairment screening tool (MoCA) will be excluded
- moderate or more severe substance dependence (assessed with the MINI)
- persons with imminent risk of physical violence to self or others
Interventions
Participants will attend two intervention sessions per week for a total of 8 sessions. Participants will sit in a chair in a sound-proof booth monitored by a researcher in front of a computer screen (which delivers instructions) and will be fitted with psychophysiology leads and a device strapped around the chest. There will be no explicit tasks or direction given in this intervention. Participants will experience smooth slowly varying breath-like vibration on their sternum. They will receive their assigned intervention for approximately 18 minutes.

Participants will engage in a period of no-screen time; during this time there will be no outside visual or auditory distractions.
