Narrative exposure therapy is effective for traumatized survivors

Sep 22 2009

A group of German investigators performed a controlled study on psychological help for Rwanda orphans of war. Twenty-six orphans (originally 27) who presented with posttraumatic stress disorder (PTSD) at first assessment continued to meet a PTSD DSM-IV diagnosis 6 months after their initial assessment. They were offered participation in a controlled treatment trial. A group adaptation of interpersonal psychotherapy (IPT, n = 14) was compared to individual narrative exposure therapy (NET, n = 12). The last NET session involved guided mourning. Each treatment program consisted of 4 weekly sessions. Main outcome measures were diagnostic status and symptoms of PTSD and depression assessed before treatment, at 3 months post-test and at 6 months follow-up using the Clinician-Administered PTSD Scale, Mini-International Neuropsychiatric Interview, and Hamilton Rating Scale.

At post-test, there were no significant group differences between NET and IPT on any of the examined outcome measures. At 6-month follow-up, only 25% of NET, but 71% of IPT participants still fulfilled PTSD criteria. There was a significant time × treatment interaction in the severity of PTSD [p < 0.05] and depression symptoms [p = 0.05]. At follow-up, NET participants were significantly more improved than IPT participants with respect to both the severity of symptoms of PTSD and depression.

Individual NET in combination with group-based mourning comprises an effective treatment for traumatized survivors who have to bear the loss of loved ones and have been suffering from symptoms of PTSD and depression.
