Brief Summary in Lay Language

Traumatic life events can lead, depending on in which age they occur, to a post traumatic stress disorder, a constant personality change, a personality disorder or to other symptom pictures. These disturbance pictures often overlap, it means are given together.
In my study I would like to investigate the specific personality profile of people with the diagnosis of a post traumatic stress disorder, so that people with this diagnosis can be better distinguished from people that suffer under other symptom pictures. It would improve the diagnosis and this would have an effect on the choice of the suitable therapy.
For my study I search at least 30 people with the diagnosis or suspicion on a post traumatic stress disorder, no matter whether additional diagnoses are given or not, 30 people with chronic pains which are therefore in medical treatment, and 30 people without diagnosis of a psychic - or behavioural disorder

The study is built up of 4 questionnaires. 2 questionnaires to incriminating events and 2 personality questionnaires are presented to all participants. Procedure duration 2-3 hours (or 2 x 1.5 hours).
I expect that people fulfiling the diagnosis criteria of a post traumatic stress disorder will show a specific personality profile, as opposed to other people.

Brief Summary in Scientific Language

Comorbidity of PTSD with axis II disorders is a consistent result of epidemiological studies. Borderline- or anti-social personality disorders is brought most often in connection with the PTSD. Today, by the progress of the research for personality disorders, there are available more exact personality inventories which could be used for assessment personality pathology in the PTSD population. Wolf, Hamington and Miller (2011) describe, as one of first, a specific profile for PTSD with a topical personality inventory, by SNAP. They show that the scale „negative temperament“ (another name for neurotizismus, negative affect, emotional dysregulation) points to general distress and is not specifically for the PTSD. They illustrate that scales „eccentric perception“, "detachment" and "aggression" are specific for the PTSD.
The present study shall with help of the DAPP-BQ (a topical personality inventory which shows a high connection with the SNAP)describe a specific profile for PTSD and check the following central hypothesis: the people who fulfill the diagnosis criteria of the PTSD and not the diagnosis criteria of a personality disorder show a specific DAPP-BQ – profile.

Sample: 30 people without ICD 10 (F) diagnosis, 30 chronic pain patients, 30 PTSD patients.
The used procedures which are to be filled by all participants:
1. The DAPP-BQ and the NEO‐PI‐R are used to describe extreme personality traits. Both are international set up, reliable and valid selfjudgement questionnaires which describe pathological personality dimensional.
2. To describe PTSD two questionnaires, which belong to the most-used trauma-diagnostic instruments are used: PDS and IES-R.
A specific personality profile of PTSD patients can bring clarity of high comorbidity with DSM-IV axis II disorders.

Primary Outcome

2 personality questionnaires are to filled by all participants:

1. DAPP-BQ (Dimensional Assesstment of Personality Pathology - BASIC Questionnaire - German version of Ostendorf, F., Angleitner, A., Riemann, R. , 290 Items).
2. NEO-PI-R (NEO personality inventory revised version - German version of Ostendorf, F., & Angleitner, A. (2004), 241 Items).
People without diagnosis post traumatic stress disorder fill in the questionnaires autonomously. Pain patients and patients with post traumatic stress disorder fill in the questionnaires independently in presence of the study-authorized person.

Secondary Outcome

2 questionnaires to incriminating events are to filled by all participants:
1. IES-R (Impact of event scale – revised version - German version of Maercker & Schützwohl (1998), 22 Items)
2. PDS (Post traumatic diagnosis scale - German version of Ehlers, Steil & Winter (1996), 46 Items).
People without diagnosis post traumatic stress disorder fill in the questionnaires autonomously. Instead of a traumatic event this group enlist the worst experienced event and values his magnitude. Pain patients and patients with post traumatic stress disorder fill in the questionnaires independently in presence of the study-authorized person.
