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

BACKGROUND

Children 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.

OBJECTIVE

In 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

SETTING

Participants 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.

RESULTS

Both 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.

CONCLUSIONS

Findings 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.
