This study shows a new way to induce dissociation in people with PTSD. The dissociative induction method effectively increased state dissociation in participants, offering a new laboratory tool.

Area of Science:

  • Psychology
  • Trauma Studies
  • Clinical Psychology

Background:

  • Dissociation is a common response to trauma, but research often relies on retrospective accounts.
  • Understanding dissociative experiences in real-time is crucial for developing effective interventions.

Purpose of the Study:

  • To investigate a non-pharmacological method for inducing state dissociation.
  • To examine the effectiveness of a dissociative induction procedure in a clinical sample, including individuals with PTSD.

Main Methods:

  • A modified Velten mood induction procedure was used to create two induction conditions: dissociative and serenity.
  • Participants with PTSD and non-trauma-exposed controls were randomly assigned to one of the induction conditions.
  • State dissociation, trait dissociation, PTSD severity, and depression were measured.

Main Results:

  • Participants in the dissociative induction group reported significantly higher state dissociation than those in the serenity induction group.
  • The PTSD group exhibited greater state dissociation compared to the non-trauma-exposed group, irrespective of the induction method.
  • State dissociation levels were correlated with trait dissociation, PTSD severity, and depression symptoms.

Conclusions:

  • The study successfully demonstrated the feasibility of inducing state dissociation in a laboratory setting using a non-pharmacological method.
  • This induction technique shows promise as a tool for further research on dissociation in clinical populations, particularly PTSD.
  • Findings highlight the potential for real-time study of dissociative phenomena in trauma survivors.
