Background: Intensive treatment programmes (ITPs) for posttraumatic stress disorder (PTSD) produce large symptom reductions and have generally higher completion rates compared to traditional weekly care. Although ITPs do not appear to increase substance use, it has yet to be determined whether their effectiveness differs for veterans with and without hazardous alcohol use (HAU).

Do Eye Movement and Desensitization and Reprocessing (EMDR) therapy affect the accuracy of memories? This recurrent issue in recent memory research bears relevance to expert witness work in the courtroom. In this review, we will argue that several crucial aspects of EMDR may be detrimental to memory.

First, research has shown that eye movements undermine the quality and quantity of memory. Specifically, eye movements have been shown to decrease the vividness and emotionality of autobiographical experiences and amplify spontaneous false memory levels.

Several types of psychological treatment for posttraumatic stress disorder (PTSD) are considered well established and effective, but evidence of their long-term efficacy is limited.

Objective: This constitutes the first meta-analysis investigating whether patients with and without comorbid personality disorders can equally benefit from psychotherapy for PTSD.

Method: A systematic literature search was conducted in PubMed, EMBASE, PsychINFO and Cochrane databases from inception through 31 January 2020, to identify clinical trials examining psychotherapies for PTSD in PTSD patients with and without comorbid personality disorders (PROSPERO reference CRD42020156472).
