Objective: Trauma-therapy in children and adolescents often involves the inclusion of their parents. A multi-informant approach was used to investigate whether trauma-focused cognitive-behavioral therapy (TF-CBT) changes dysfunctional posttraumatic cognitions (PTCs) in participating parents. This, in turn, may mediate their child's posttraumatic stress symptoms (PTSS) posttreatment.
Method: Children and adolescents (6-17 years old) were assigned to either a TF-CBT (n = 57) or a waitlist (n = 56) condition, within a multisite randomized controlled trial conducted in Germany. They were assessed using the Clinician Administered PTSD Scale for Children and Adolescents, version for DSM-IV and they completed the University of California at Los Angeles Post-Traumatic Stress Disorder Reaction Index for Children and Adolescents (UCLA). Their parents completed the UCLA, caregiver report, and the Posttraumatic Cognitions Inventory to rate their dysfunctional PTCs related to their child's trauma. The mediation hypothesis was tested using a multiple mediation model.
Results: The change in parental PTCs was stronger in the TF-CBT condition (b = 13.19, 95% confidence interval [CI] [2.89, 23.49]). It mediated the relationship between the group (TF-CBT vs. waitlist) and the caregiver report on the child's PTSS (b = -.08, 95% CI [-.15, -.01]), but not the child's PTSS, assessed using the interview (b = .01, 95% CI [-.14, .17]) and the self-report questionnaire (b = .01, 95% CI [-.08, .10]), posttreatment.
Conclusions: TF-CBT helped participating parents to challenge their dysfunctional PTCs related to their child's trauma. The change in parental PTCs only mediated their perception of their child's PTSS but not their child's self-perception or the clinical evaluation of their child's PTSS.
