Peritraumatic Dissociative Experiences Questionnaire Test

People seeking a clearer picture of unusual reactions during or immediately after a traumatic event may find the Peritraumatic Dissociative Experiences Questionnaire Test useful. It focuses on experiences such as detachment, unreality, automatic behavior, and altered awareness. As a peritraumatic dissociation test, it helps the respondent organize these experiences into a single result without requiring a detailed retelling of the event.

What This Assessment Explores

The questionnaire examines dissociation during or immediately after a traumatic event. Items address unreality, automatic action, altered time, observer-like distance, bodily detachment, awareness gaps, and muted pain. As a trauma dissociation questionnaire, it describes reported severity rather than the event's severity.

The items cover these themes within that single displayed result:

• Questions about unreality, altered time, and automatic action ask about changes in reality contact, control, or temporal experience.
• Questions about observer and body detachment ask about distance from the scene or a changed bodily presence.
• Questions about gaps in awareness and muted pain ask about reduced noticing of events or injury.

The Peritraumatic Dissociation Scale runs from 9-45: Low (9-20), Moderate (21-33), and High (34-45). Higher scores may indicate more pronounced dissociative symptoms, including unreality, detachment, or reduced reality contact, a pattern used in clinical and research settings to identify risk for posttraumatic disorders.

Methodology and Scientific Basis

Each prompt describes a possible reaction and the questionnaire presents five ordered choices, moving from false or not true toward completely or very true. It displays one scale with result bands but does not specify how individual responses are calculated or weighted.

The questionnaire is conceptually consistent with the published PDEQ, the instrument most directly aligned with these content domains. This online questionnaire is not established here as a direct adaptation of that instrument. Marshall and colleagues studied a modified version in 2002, Birmes and colleagues examined a self-report version in two French-speaking trauma-exposed samples in 2005, and Bryant and colleagues investigated its latent structure in 2009.

Those studies support the relevance of trauma-related dissociation as a construct, but they do not establish norms for this online presentation. A higher score may indicate more pronounced or severe reported dissociative experiences; it is not proof of a posttraumatic disorder or clinical diagnosis. Because answers depend on recall, self-awareness, and willingness to report, current context can influence the result.
