[Frequency and Type of Traumatic Events in Children and Adolescents with a Posttraumatic Stress Disorder].

The risk for children and adolescents to be exposed to a potentially traumatic event (PTE) is high. The present study examines the frequency of PTEs in children and adolescents with Posttraumatic Stress Disorder (PTSD), the type of index trauma, and its relation to PTSD symptom severity and gender. A clinical sample of 159 children and adolescents between 7-16 years was assessed using the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA). All reported PTEs from the checklist were analyzed according to frequency. The index events were categorized according to the following categories: cause (random vs. intentional), relation to offender (intrafamilial vs. extrafamilial), patient's role (victim, witness or vicarious traumatization), and type of PTE (physical or sexual violence). Relation between categories and PTSD symptom severity and sex were analyzed with inferential statistics. On average participants reported five PTEs, most frequently physical violence without weapons (57.9%), loss of loved person through death (45.9%), and sexual abuse/assaults (44%). The most frequent index traumata were intentional (76.7%). Regarding trauma type, there was a significant difference concerning higher symptom severity in children and adolescents who experienced sexual abuse/assault compared to physical violence (t=-1.913(109), p=0.05). A significantly higher symptom severity was found for girls compared to boys for the trauma categories extrafamilial offender (z=-2,27, p=0.02), victim (z=-2,11, p=0,04), and sexual abuse/assault (z=-2,43, p=0,01). Clinical and diagnostic implications are discussed in relation to the amendments of PTSD diagnostic criteria in DSM-5.
