Purpose
For several years now, a very successful treatment of posttraumatic stress disorders has been offered in the Netherlands and in Germany. The contact between clients and therapists takes place exclusively via Internet. The therapists follow a scientifically tested treatment protocol, that defines fixed treatment elements that are adapted to the specific situation of the client. The participants can write at home, in their familiar environment which makes it easier to work on trauma related issues with their therapist. In the last years the treatment was offered in Arabic as well indicating to be an effective treatment for Posttraumatic Stress Disorder (PTSD) in Arabic-speaking countries.
The treatment lasts five weeks. During that time-frame, participants write several texts. The participants decide when they want to write. Each time after having received two texts, the therapists provide feedback and further instructions. The therapists are all trained psychologists, who have received additional training in the interpretation of texts and for the application of the treatment protocol.
The investigators hypothesize that both interventions will significantly improve clinical symptoms of PTSD. Furthermore, the investigators expect improvements in secondary outcomes such as anxiety, depression and quality of life.

Experimental: Treatment of PTSD with cognitive restructuring
In this arm the PTSD treatment can be divided into three phases. First phase: self-confrontation (4 essays) Second phase: cognitive restructuring (4 essays) Third phase: parting (2 essays) |
Behavioral: Exposure for PTSD with cognitive restructuring
The treatment lasts five weeks. During that time-frame, participants write ten texts for 45 minutes, twice a week. Each time after having received two texts, the therapists provide feedback and further instructions, which are based upon the manual (Lange et al., 2003) The long version of the PTSD treatment (including cognitive restructuring) can be divided into three phases. First phase - self-confrontation (4 essays) At the beginning the participants receive psychoeducation about the mechanisms of exposure before writing four essays about their emotionally most painful memories. Second phase - cognitive restructuring (4 essays) Again the participants write four texts, however, this time they go beyond mere descriptions and use their experiences to write a supportive letter to an imaginary friend who had been through the same experience. Third phase - parting (2 essays) In the third phase, two texts are written in the form of a letter to document the past in a worthy document. |

Experimental: Treatment of PTSD without cognitive restructuring
In this arm the PTSD treatment can be divided into only two phases. Compared to the other arm the phase dealing with cognitive restructuring is excluded. First phase: self-confrontation (4 essays) Second phase: parting (2 essays) |
Behavioral: Exposure for PTSD without cognitive restructuring
The treatment lasts five weeks. During that time-frame, participants write ten texts for approximately 45 minutes, twice a week. Each time after having received two texts, the therapists provide feedback and further instructions, which are based upon the manual (Lange et al., 2003). The short version of the PTSD treatment can be divided into only two phases. Compared to the long version the phase dealing with cognitive restructuring is excluded. First phase - self-confrontation (4 essays) At the beginning the participants receive psychoeducation about the mechanisms of exposure before writing four essays about their emotionally most painful memories. Third phase - parting (2 essays) In the third phase, two texts are written in the form of a letter to document the past in a worthy document. |
Detailed Description:
Background:
For several years now, a very successful treatment of posttraumatic stress disorders has been offered in the Netherlands and in Germany. The contact between clients and therapists takes place exclusively via Internet. The therapists follow a scientifically tested treatment protocol, that defines fixed treatment elements that are adapted to the specific situation of the client. The participants can write at home, in their familiar environment which makes it easier to work on trauma related issues with their therapist. In the last years the treatment was offered in Arabic as well indicating to be an effective treatment for PTSD in Arabic-speaking countries.
Method:
Traumatized Arabic-speaking participants are allocated at random to a long version (10 sessions) of a manualized writing approach over 6 weeks or to a short version, where the part concerning the cognitive restructuring is excluded. The investigators expect the treatment to be useful for traumatized clients, especially for those who have no access to psychological help otherwise and they hypothesize that both interventions will significantly improve clinical symptoms of PTSD. Furthermore, the investigators expect improvements in secondary outcomes such as anxiety, depression and quality of life. Additionally the investigators are interested, if the short form where the cognitive part is excluded and the focus will be more on confrontation is effective similarly.
Conclusion:
If the interventions prove to be an effective treatment for PTSD in Arabic-speaking countries, the results will lend to support to the establishment of internet-based approaches, especially in countries, where face-to-face therapy cannot be provided. Furthermore a shorter treatment could improve the compliance of the participants, particularly in post-conflict regions where people cannot attend long therapeutic interventions.
