Dissociation within PTSD – evidence

Dissociation in Posttraumatic Stress Disorder: Evidence from the World Mental Health Surveys

The DSM-5 added a new dissociative subtype of Posttraumatic Stress Disorder (PTSD) last year, but before this was finalized there were concerns that the majority of the evidence for the dissociative subtype of PTSD came from Western counties. The research described here consisted of interviews with over 25,000 respondents across 16 countries in the World Health Organization World Mental Health Surveys in order to assess whether this differed between low/middle and high income countries, and whether this was consistent across a diverse set of countries.

The results showed that dissociative symptoms within PTSD did not differ between high and low/middle income countries after 12 months. Dissociative symptoms were present in over 14% of those with PTSD, and were associated with a number of different factors including more re-experiencing symptoms (for example, flashbacks), high exposure to prior trauma, suicidality and childhood onset of PTSD.
