TY - JOUR AB - Purpose The purpose of this paper is to investigate the changes in posttraumatic stress disorder (PTSD) symptomatology during treatment in a drug and alcohol therapeutic community.Design/methodology/approach A repeated measures design was employed that looked at PTSD, depression, anxiety, and stress at a pre- and post-timepoint. A second sample was then evaluated at time of program completion to seven months post-treatment.Findings PTSD symptomatology significantly decreased in individuals who had undertaken treatment, and continued to decline post-treatment. This finding was irrespective of any PTSD-specific treatment.Research limitations/implications PTSD specific treatment is not necessary to lower the symptomatology. Furthermore, this provides evidence that PTSD and substance use disorders are so highly intertwined that the comorbidity can almost be considered a single, diagnosis.Originality/value This is a partial replication of previous research which had not previously been replicated. This research also adds to the limited research which looks at PTSD from the perspective of drug and alcohol rehabilitation.
