Reporting of potentially traumatic events (PTEs) in post-traumatic stress disorder (PTSD) research is inconsistent. Many participants either failed to report PTEs in earlier interviews or reported them for the first time years later.

Area of Science:

  • Psychiatry
  • Epidemiology
  • Psychological Trauma Research

Background:

  • Post-traumatic stress disorder (PTSD) research heavily relies on self-reported trauma exposure.
  • Understanding the reliability of self-reports is crucial for accurate PTSD diagnosis and treatment.

Purpose of the Study:

  • To assess the consistency of reporting potentially traumatic events (PTEs) over time in a community-based cohort.
  • To evaluate the reliability of self-reported trauma history in longitudinal PTSD studies.

Main Methods:

  • A community-based cohort in Zurich, Switzerland, was followed from age 34-35 (1993) to 40-41 (1999).
  • Participants underwent semi-structured diagnostic interviews, including a PTSD module, at both time points.

Main Results:

  • Of 342 participants interviewed twice, 169 reported PTEs. A significant number (33.1%) reported previously undisclosed PTEs in the later interview.
  • Conversely, 40.2% of those reporting a PTE in 1993 did not report it in 1999.
  • The overall inconsistency rate in reporting PTEs between the two interviews was 63.9%.

Conclusions:

  • High inconsistency in reporting potentially traumatic events (PTEs) challenges the reliability of self-report data in PTSD research.
  • These findings have significant implications for therapeutic interventions and the validity of epidemiological studies on trauma.
  • Future research should consider methods to improve the accuracy and consistency of trauma recall in longitudinal studies.
