The role of therapy delivery and clinic organizational factors in explaining therapist effects for trauma-focused psychotherapies in the Veterans Health Administration.

OBJECTIVE: This study estimated the size of therapist effects (TEs) for dropout and clinical effectiveness of two trauma-focused psychotherapies (TFPs) and evaluated whether therapy delivery and clinic organizational factors explained observed TEs. METHOD: = 1,273), clinically meaningful improvement and recovery based on posttraumatic stress disorder checklist for DSM-5 (PCL-5) scores. Therapist-level predictors were ascertained through survey, manual chart review, and administrative data. Multilevel models estimated TEs. TEs were nonsignificant for clinically meaningful improvement and recovery. CONCLUSIONS: Interventions targeting therapy delivery and clinic organization have the potential to reduce variation between therapists in TFP dropout, so that more patients stay engaged long enough to experience clinical benefit.
