[Epidemiology of trauma, PTSD and complex PTSD in the Netherlands].

BACKGROUND

There is no recent data available on the prevalence of trauma, PTSD and complex PTSD in the Netherlands.

AIM: To determine the prevalence of trauma, DSM-5 PTSD, and ICD-11 PTSD and complex PTSD.

METHOD: A sample of 1,690 Dutch adults was recruited through the LISS panel between September and November, 2023. A subsample (n = 204) participated in a structured clinical interview.

RESULTS

The estimated lifetime prevalence of DSM-5 PTSD was 11.1%, and 1.3% currently meets criteria for DSM-5 PTSD. The estimated current prevalence of ICD-11 PTSD was 1.3% and 1.6% for complex PTSD. Women, younger and middle-aged adults, and those with a non-Dutch cultural background were at elevated risk for developing PTSD. Approximately half of those with probable lifetime PTSD sought professional help, but only one-third received guideline treatment.

CONCLUSIONS

Potentially traumatic events, PTSD, and complex PTSD are unevenly distributed across the population. Despite the availability of evidence-based treatments, only a minority of affected individuals receive adequate care. These findings underscore the urgent need for targeted screening, preventive interventions, and public health campaigns aimed at increasing awareness about PTSD and treatment.
