abstract

  • Exposure to complex trauma is a prevalent and costly public health concern. Though not yet included in the formal diagnostic systems, developmental trauma disorder (DTD) was proposed to capture the consistent and predictable emotional, behavioral, and neurobiological sequelae observed in children exposed to complex trauma. This systematic review synthesizes and evaluates the existing empirical evidence for DTD as a reliable, valid, distinctive, and clinically useful construct. We identified 21 articles reporting on 17 non-overlapping samples that evaluated DTD symptom criteria using objective, empirical methods (e.g., factor analysis, associations with other diagnostic constructs, associations with trauma exposure type, clinician ratings of utility). Studies were largely supportive of the DTD construct and its clinical utility; however, it will be crucial for this work to be replicated in larger samples, by independent research groups, and with more rigorous methodological and analytic approaches before definitive conclusions can be drawn. Findings from this review, while preliminary, provide a promising empirical foundation for DTD and bring the field closer to improving diagnostic parsimony for children and adolescents affected by complex trauma.
