Randomized Clinical Trial of Imagery Rescripting Treatment In Veterans With Trauma-Related Nightmares And Posttraumatic Stress Disorder (PTSD)

Inclusion Criteria: Participants will be: 1. patients at the VA in the Trauma Recovery Program; 2. English-speaking; 3. reporting at least one Posttraumatic Nightmare in the past week (due to any type of trauma); 4. have an existing PTSD International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM); and 5. consenting to be randomized into treatment. In addition, patients must agree to allow their assessment and therapy sessions to be video/audiotaped for the purposes of supervision and treatment integrity ratings. Participants receiving other forms of group or individual psychotherapy and/or psychotropic medication are eligible for the nightmare treatment condition of the study, provided that those interventions do not specifically target nightmares or PTSD. Thus, the study interventions will be in addition to standard care, except as indicated above. Exclusion Criteria: Patients 1. with current active suicidal/homicidal ideation and intent; 2. with current substance dependence; 3. a diagnosis of bipolar or psychosis; 4) prescribed the medication Prazosin (a psychotropic medication for the treatment of nightmares). Patients in the nightmare treatment condition of the study will also be excluded if they are actively participating in another psychosocial treatment directly addressing their PTSD symptoms. Patients will not be excluded if they are taking psychotropic medication (except for Prazosin) and may continue to take their medication as prescribed throughout the study.
