Objective: The authors' goal was to compare the efficacy of a manualized cognitive behavior therapy that addresses both posttraumatic stress disorder (PTSD) and substance abuse (seeking safety) with a manualized cognitive behavior therapy that addresses only substance abuse (relapse prevention) and with standard community care for the treatment of comorbid posttraumatic stress disorder (PTSD) and substance use disorder.
Method: One hundred seven women from an urban, low-income population who had comorbid PTSD and substance use disorder were randomly assigned to receive the two kinds of cognitive behavior therapy or received standard community treatment. Participants were recruited from both community and clinical populations and evaluated with structured clinical instruments.
