Developmental trauma disorder (DTD) in children and adolescents - results from a patient population at the special consultation hour for traumatized children and adolescents Children and adolescents who have experienced interpersonal Type-II-trauma often develop symptoms going far beyond the Post-Traumatic Stress Disorder (PTSD). Van der Kolk (2009) suggested the Developmental Trauma Disorder (DTD) to define the extensive symptomatology; however, research on DTD is limited. Frequency and group differences of DTD were examined based on physicians' letters of = 161 patients between one and 18 years (61 % female) from an out-patient unit for traumatized patients at a paediatric and adolescent psychiatry. Physicians' letters were rated and analysed using an adapted DTD algorithm. In total, 77 % of the patients experienced interpersonal Type-II-trauma, 6 % met the criteria for the adapted DTD diagnosis. DTD criteria were found more frequently in interpersonal Type-II-trauma victims than in patients with accidental or Type-I-trauma, but group differences only reached statistical significance for the DTD criteria B (affective and physiological dysregulation) and G (impairments) at the adjusted 0,2 % significance level. No statistically significant differences for age or gender were found. The posttraumatic symptoms of children younger than seven years were analysed descriptively. The results show that, although many children and adolescents have developed symptoms beyond the PTSD, only a small proportion have met the DTD diagnosis. In view of the partially unspecific and contradictory findings, further studies on DTD considering larger samples, the complete DTD criteria, and diagnosis-specific instruments seem to be reasonable and necessary.
