description: (1) Effects of baseline psychological symptom severity on dropout from trauma-focused cognitive behavior therapy for posttraumatic stress disorder: A meta-analysis Abstract: A meta-analysis was conducted to explore the impact of baseline psychological symptom severity on treatment dropout among adults administered Trauma-Focused Cognitive Behavior Therapy (TF-CBT) for Posttraumatic Stress Disorder (PTSD). Literature on how baseline psychological symptom severity influences attrition has produced inconsistent findings. No review to date has analyzed outcomes across studies. This meta-analysis compared baseline severity scores of, a) clinician-rated PTSD symptoms, b) self-report PTSD symptoms, and c) comorbid psychological symptoms, between TF-CBT completers and dropouts. Eligible studies were peer-reviewed, original outcome research of TF-CBT trials with adults meeting diagnostic criteria for PTSD. Data included standardized and quantitative baseline scores of clinician-rated and/or self-report PTSD and comorbid psychological symptom severity for treatment completers and dropouts. Searches were conducted of PsycINFO, Web of Science and SCOPUS and resulted in the identification of 12 studies with data received for 881 adult participants with a primary diagnosis of PTSD. Nine Randomized Control Trials (RCTs) and three non-RCTs were included. The interventions in the studies were guideline-recommended and evidence-based treatments of Prolonged Exposure, Cognitive Processing Therapy and Cognitive Behavioral Therapy for PTSD. Findings revealed participants dropping out of treatment had higher clinician-rated PTSD symptom severity at baseline than those who completed, with a significant and moderate effect size observed (g = -.50, 95% CI [-0.95, -0.04], p < .05). No other findings were significant. The implications of inconsistent definitions of treatment dropout in included studies are discussed.
