Variation in the Developing Brain and the Role of Pediatric Posttraumatic Stress on Structural and Functional Networks

Toward a Developmental Model of Continuity and Change in PTSD Symptoms following Exposure to Traumatic and Adverse Experiences

A developmental understanding of the expression of posttraumatic stress (PTS) symptoms following trauma in childhood requires identifying continuity and change in not just overall symptoms but in the individual symptoms as well. Such models of change also require understanding multiple dimensions of time. That is, longitudinal change-the passage of time-may have different effects on symptom expression depending on when in time an individual entered the study - such as what age they were when first assessed. This paper addresses these ideas with an overview of the developmental differences in the assessment of PTS from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, (DSM-5), longitudinal research on posttraumatic stress disorder (PTSD) symptoms, and providing synthesis within a symptom network perspective. We then provide an illustration of how individual PTSD symptoms change over time at different ages (elementary versus middle school) with a secondary analysis of data from a previously reported study (n = 191 youth, aged 8-15, assessed at two time points six months apart). The reanalysis of the data suggests both continuity and change in symptoms over time (i.e., some symptoms were more stable than other symptoms) with differences in symptom rates and their longitudinal change as a function of age (i.e., some symptoms more common or more stable in younger versus older or older versus younger). We close with avenues for future research aimed at better understanding symptom cascades over time and at different ages and potential implications for future iterations of assessment/classification systems.

Maternal Support and Attrition from Child Trauma-Focused Therapy

Many children prematurely terminate from trauma-focused therapy (TFT), and attrition is a critical barrier in addressing the impacts of childhood sexual abuse (CSA). The field's knowledge of risk factors for dropout is growing; however, one aspect of the child's environment that remains unexamined is maternal support following the CSA disclosure/discovery. Maternal support has been theorized to play a valuable role in influencing children's outcomes after CSA and may be relevant in understanding attrition. The objective of the current study was to investigate the associations between children's symptoms, relationship to the perpetrator, and maternal support in relation to premature termination from TFT among 186 sexually abused children (M_age = 9.24 years, SD = 3.72, 67.3% female). Two operational definitions of attrition were used: (a) clinician-rated dropout (i.e., clinician's ratings of whether the child completed treatment) and (b) whether the child received an adequate treatment dose treatment (i.e., ≥12 sessions). Maternal marital status was the only factor associated with clinician-rated treatment dropout, OR = 2.35, whereas maternal support and blame/doubt were unrelated. Living farther from the clinic was tied to an increased risk of receiving an inadequate treatment dose, OR = 0.96. Replication of these findings is needed, particularly using a clinician-administered measure of caregiver support; yet, maternal emotional support and blame/doubt may not evince strong ties to dropout from TFT among sexually abused children. Additional work is needed to discern if there are key subgroups for whom support is more strongly related to the risk of premature termination following CSA.
