Peritraumatic dissociation is a moderate risk factor for developing Posttraumatic Stress Disorder (PTSD). This meta-analysis of 35 studies confirms a significant positive correlation, supporting its role in PTSD development.

Area of Science:

Psychology
Psychiatry
Trauma Studies

Background:

Peritraumatic dissociation is widely recognized as a potential risk factor for Posttraumatic Stress Disorder (PTSD).
Numerous studies have explored the relationship between peritraumatic dissociation and PTSD.
A systematic integration of existing research is needed to clarify this association.

Purpose of the Study:

To systematically integrate findings from empirical studies on the connection between peritraumatic dissociation and PTSD.
To differentiate between peritraumatic dissociation as a correlate versus a risk factor for PTSD.
To assess the predictive value of peritraumatic dissociation for PTSD development.

Main Methods:

Conducted a meta-analysis of 35 empirical studies examining the link between peritraumatic dissociation and PTSD.

Related Experiment Videos

Calculated an overall effect size for the correlation.

Performed subgroup analyses on quasi-prospective and retrospective studies to evaluate PTSD risk.

Main Results:

A significant positive correlation (r=0.36) was found between peritraumatic dissociation and PTSD.
Quasi-prospective studies showed a significant effect size (r=0.34), indicating a moderate risk.
Methodological analysis supports peritraumatic dissociation as a moderate risk factor for PTSD.

Conclusions:

Peritraumatic dissociation is confirmed as a moderate risk factor for developing PTSD.
Further research is required to fully understand its conceptualization within psychotraumatic stress syndromes (e.g., predictor, symptom).
The findings underscore the importance of addressing peritraumatic dissociation in trauma-focused interventions.
