Attrition from pediatric trauma-focused cognitive behavioral therapy: A meta-analysis

Trauma-focused cognitive behavioral therapy (TF-CBT) is one of the leading interventions for trauma-exposed children and adolescents and is associated with significant improvements in a variety of trauma-related symptoms. Nonetheless, attrition from TF-CBT is quite common, and children who do not receive the full intervention may continue to suffer from trauma-related symptoms. Rates of premature termination have varied across studies, and to date, no meta-analyses have been conducted regarding dropout from TF-CBT. The objective of the present study was to conduct a meta-analysis of the rates of attrition from TF-CBT, as well as review factors related to premature termination from this intervention. A total of 22 studies were available for inclusion in this meta-analysis. The prevalence of attrition was 33.9% (95% CI [26.2%, 42.5%]) from 2,059 children receiving TF-CBT. Clinician-rated attrition was 38.5%, and 17.5% did not receive an adequate dose of TF-CBT (e.g., 12+ sessions). Further, the study type was related to differing rates of dropout, with randomized controlled trials having a much lower attrition rate. Regarding risk factors for premature termination, the emerging literature suggests that a child's age, racial-ethnic minority status, and symptom levels may evince some ties to attrition. Caregiver, family, therapist, and treatment factors remain underexplored in relation to premature termination; however, preliminary work suggests that lack of caregiver attendance and difficulty in the child-therapist relationship may be related to attrition. A substantial number of children prematurely terminate from TF-CBT, underscoring the need to better prevent dropout.
