This study evaluates a new behavioral therapy model, Creating Change (CC) for PTSD/SUD. CC helps clients explore the past as a step in their recovery process. It has major public health relevance in that it is a low-cost, flexible model designed for all trauma and substance abuse types, both genders, and all clinical settings. It has particular relevance for VA in that many veterans suffer from PTSD and SUD. The new model demonstrated positive results in two pilot studies.
