Victims of traumatic experiences can experience symptoms of re-living, avoidance, and change in emotions and cognitions, as well as psychophysiological hyper arousal, which are summarised as post-traumatic stress disorders (APA, 2013). With a lifetime prevalence of 7.8% (Kessler, Sonnega, Bromet, Hughes, & Nelson, 1995), posttraumatic stress disorders (PTSD) are counted among the most frequently psychiatric diagnoses or clinical pictures. In this regard however, PTSD does not typically arise in isolation, but is frequently accompanied by comorbid clinical pictures: "A lifetime history of at least one other disorder was present in 88.3% of the men with lifetime PTSD and 79% of the women with lifetime PTSD." (Kessler et al., 1995, S. 1055). A further important aspect of the comorbidity rate is the indication of diagnostic artefacts resulting from the overlapping of symptoms between differing diagnoses (McMillen, North, Mosley, & Smith, 2002). This phenomenon is also of critical importance for classifying the high comorbidity rates of PTSD with anxiety disorders such as social phobia (SP) or agoraphobia (AP) (e.g. Alonso et al., 2004; Davidson, Hughes, Blazer, & George, 1991; Davis et al., 2012; Zhang, Ross, & Davidson, 2004), because all three diagnoses attribute a central position to avoidance symptoms.
The study proposed would like to make a contribution to understanding avoidance symptoms in the conflicting areas between PTSD, AP und SP. The intention is to examine in the context of a qualitative pilot project if and to what extent with female and male German Bundeswehr army soldiers who have been diagnosed with PTSD and/or AP and/or SP, the avoidance symptoms concern differing phenomena or the same, repeatedly diagnosed symptoms.
