This investigation is one of the first to assess the statewide implementation of a popular trauma-focused EBT for youth in routine practice settings. Using nine years of baseline and follow-up data, this investigation examined the implementation of Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) with 2,980 clients, 596 clinicians, and 75 community practice agencies. Clients were highly traumatized, reporting exposure to an average of four trauma types (SD = 2.85). Multilevel modeling indicated that clients participating in TF-CBT demonstrated statistically significant reductions in posttraumatic stress symptomatology from baseline to follow-up, as well as self- and parent-reported reductions in emotional symptoms, conduct problems, hyperactivity-inattention, peer problems, and the overall impact of these difficulties from baseline to follow-up. Clients also showed a statistically significant self- and parent-reported improvement in prosocial relations from baseline to follow-up. Although clinician TF-CBT implementation fidelity was not related to changes in client outcomes from baseline to follow-up, both clinician license and supervisory status were statistically significantly related to implementation fidelity score. Findings suggest that the large-scale implementation of TF-CBT is a promising approach to increasing the availability of trauma-focused EBTs in routine practice settings, while also reducing the primary and secondary effects of trauma in the lives of children and their families.enEvidence-based treatmentImplementationPTSDTF-CBTTraumaThesis or Dissertation
