Examining the effectiveness of trauma-focused cognitive behavioral therapy on children and adolescents' executive function

Abstract

BackgroundChildren and adolescents impacted by childhood trauma often demonstrate executive function difficulties, which negatively affect self-regulation and potentiate the risk for trauma-related psychopathology and functional impairment. Evidence-based treatments for traumatized youth such as Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) aim to equip youth directly with skills for effective self-regulation and may thus also improve executive function. Moreover, adolescence is a sensitive period for executive function development, and interventions aimed at improving executive function may confer greater benefits for adolescents relative to school-aged children. No study has examined executive function improvements during TF-CBT or the potential differences in these outcomes between children and adolescents. ObjectiveIn the current study, we examined changes in caregiver-reported executive function difficulties during TF-CBT among children ages 6 to 11 and adolescents ages 12 to 17. Participants and settingParticipants were 278 racially and ethnically diverse youth with interpersonal trauma histories and their caregivers enrolled in a community-based effectiveness trial of TF-CBT in an urban setting. Caregivers reported on youth executive function at pre, mid, and posttreatment assessments. ResultsBoth children and adolescents demonstrated reductions in global executive function difficulties during TF-CBT. Improvements were seen across domains of emotional, behavioral, and attentional control and problem solving, with larger effect sizes for adolescents. Follow-up analyses indicated that executive function improvements were positively associated with PTSD symptom reduction in adolescents, but not in children. ConclusionsFindings add to the growing evidence of the effectiveness of TF-CBT among youth and highlight caregiver-reported executive function as a potential treatment target during TF-CBT.
