Clinical Trial Summary

Complex Post traumatic Stress Disorder (CPTSD) is now recognized as a separate trauma-based psychological condition to PTSD. CPTSD is a broader diagnosis that includes the core PTSD symptoms (re-experiencing in the here and now, avoidance, and sense of current threat) plus an additional set of symptoms that are collectively referred to as 'disturbances in self-organisation' (DSO). DSO symptoms capture pervasive psychological disturbances that are associated with traumatic exposures and that are distributed across three clusters: difficulties in affect regulation (AR), negative self-concept (NSC), and disturbances in relationships (DR). There are no effective interventions for CPTSD. It is therefore of paramount important to identify effective interventions to treat veterans with CPTSD. The present study will be one of the first to investigate the effectiveness of a novel, modular intervention for CPTSD. Enhanced Skills Training in Affective and Interpersonal Regulation (ESTAIR) is a person-centered intervention that involves targeting the symptoms of CPTSD clusters sequentially using concrete modules (i.e., specific number of sessions targeting specific clusters of symptoms). The overall aim of this study is to establish the feasibility, acceptability and preliminary effects of ESTAIR in treating CPTSD. To achieve these aims, the investigators will conduct a pilot randomised controlled trial (RCT), with a sample of 60 military veterans meeting the diagnostic criteria for CPTSD, and with two treatment arms: ESTAIR vs. a treatment-as-usual (TAU) condition.
