Therapeutic alliance in psychological therapy for posttraumatic stress disorder: A systematic review and meta-analysis.

This is the first review to demonstrate that therapeutic alliance is a consistent predictor of PTSD outcomes, in both in-person and remote therapies, and the effect appears at least as strong as in other populations. This is of relevance to clinicians working with traumatized populations. The review identified a need for further research to determine variables predicting alliance in therapy for PTSD.
