Lay Summary
|
Background and study aims:
Recent research indicates that posttraumatic stress disorder can be treated effectively. The study compares two forms of a psychological treatment for posttraumatic stress disorder named Cognitive Therapy for PTSD. There is already evidence that this treatment is effective, but we do not know what way of delivering the treatment is the most effective and most acceptable to patients.
Who can participate?
Adults suffering from posttraumatic stress disorder as a result of traumas in adulthood (e.g., assault, accidents, disaster) who can regularly attend treatment sessions either in South London or Oxford.
What does the study involve?
Participants will receive one of the two forms of psychological treatment for posttraumatic stress disorder that are being compared in the study. No drugs are involved in the treatment. Two thirds of the participants will start treatment right away. The remaining third will wait 3 months before starting treatment, and will then receive one of the forms of psychological treatment. The decision about which treatment participants receive and when they start treatment will be made by chance.
In the first three months of treatment, participants receive either up to 12 weekly sessions with a therapist or up to 6 sessions with a therapist and 6 home sessions where they work through the therapy materials at their own pace. In the following three months, they receive either up to 3 or up to 2 further sessions with the therapist.
Before and after treatment (or waiting for treatment), participants complete a number of assessments to monitor their improvement. They are interviewed and asked to fill in a number of questionnaires before, midway through and after the first three months of treatment, and three months, six months, one year and two years later.
What are the possible benefits and risks of participating?
All participants will receive an effective psychological treatment. The treatment involves talking and writing about the participants' memories of their trauma, and participants may experience short-term distress when confronting their memories. The discussion of the traumatic experience will be handled with sensitivity. Previous results showed that the treatment is well tolerated.
