Abstract

Purpose: Epidemiologic research on traumatic stress is limited in Norway. Prevalence and correlates of exposure to potentially traumatic events (PTEs) and posttraumatic stress disorder (PTSD), and patterns of comorbidity with DSM-IV Axis I and II disorders were examined in an epidemiologic sample.

Methods: Demographics, PTEs and resulting PTSD, and comorbid DSM-IV diagnoses were assessed in 2,794 members of the Norwegian Institute of Public Health Twin Panel. The sample comprised 37% male, with an average age of 28.2 years (SD = 3.9).

Results: Approximately, one-quarter of participants had lifetime PTE exposure; most PTEs were more common in men than in women. Lifetime prevalence of PTSD was 2.6%, and was significantly more common in women than men. Being female and type of PTE (both interpersonal and accidental traumatic events) were associated with increased PTSD symptoms, whereas higher education was associated with lower symptoms. PTSD was related to increased odds of most Axis I and II conditions.

Conclusions: PTE exposure and PTSD prevalence were lower than in the USA, but comparable to other European countries. Sex differences replicated previous research. The relationship between PTSD and borderline personality disorder was significantly stronger than the relationship between PTSD and any other Axis II conditions.
