Posttraumatic risk‐seeking from a neurodevelopmental network perspective

Introduction to the Special Section: Developmental Perspectives on Trauma Exposure and Posttraumatic Stress

This article provides an introduction and overview of the current special section devoted to developmental perspectives on trauma exposure and posttraumatic stress reactions. Although there have been many revisions to the posttraumatic stress disorder (PTSD) diagnosis in the four decades that have ensued since its inclusion in our diagnostic systems, and many decades of empirical and clinical work investigating the differential effects of traumatic stress on children and adolescents, a truly developmental perspective is still lacking in the diagnosis. In a call to address this gap, this article outlines principles of developmental psychopathology as applied to the phenomenology of trauma and points to potential developmental transformations in the expression of posttraumatic stress across developmental epochs. The introduction then goes on to describe the valuable contributions to the literature represented by the six teams of contributing authors to this present special section, in which they discuss stability and change in posttraumatic symptom expression across development, the current state of validation research on the proposed diagnosis of Developmental Trauma Disorder, complex symptom arrays in children who have been complexly traumatized, distinctions between Complex PTSD and emerging personality pathology, developmental perspectives on prolonged grief, and developmental considerations for understanding the intersection between trauma and moral injury. It is hoped that this collection of articles will serve to stimulate new research and inform effective interventions for young persons affected by traumatic stress.

Investigating the Association Between Posttraumatic Risky Behavior and Offending in Adolescents Involved in the Juvenile Justice System

Risky behavior is common among traumatized youth and is associated with juvenile offending. This study examined predictors of posttraumatic risky behavior, the unique contribution of posttraumatic risky behavior in predicting offending, and tested whether a distinct class of youth was characterized by high levels of posttraumatic risky behavior. Participants were 400 adolescents (25% girls) between the ages of 12 and 19 years old (M = 15.97, SD = 1.25) who were involved in the Utah juvenile justice system. Approximately 54% of the sample identified as an ethnic minority. Youth completed self-report measures of trauma exposure, posttraumatic risky behavior, posttraumatic stress symptom severity, and offending. Formal legal records of offending were also collected. The results indicated that female sex was significantly related to posttraumatic risky behavior, though age was not significantly associated with posttraumatic risky behavior. Age and ethnicity were associated with both self-reported and formal offending, and male sex was associated with formal offending. Posttraumatic risky behavior was not related to formal offending, but was related to self-reported offending in some of the tested models. Latent class analysis identified 92 youth characterized by high levels of posttraumatic risky behavior; these youth also evidenced the highest rates of trauma exposure, posttraumatic stress symptom severity, and self-reported offending. There were no ethnic, age, or sex differences between youth in the high and low posttraumatic risky behavior groups. These results add to the extant literature documenting the associations among exposure to trauma, posttraumatic stress, and juvenile offending.
