Increase of frequency of post-traumatic stress disorder in disabled war veterans during prolonged stay in a rehabilitation hospital.

Aim: To explore possible causative factors in the development of post-traumatic stress disorder (PTSD) in disabled Croatian war veterans.

Method: The sample comprised 42 disabled Croatian war veterans, aged 19 to 44 years, accommodated in the VaraZdinske Toplice Rehabilitation Hospital for the purpose of long-term physical rehabilitation. Manifestation of PTSD symptoms (Mississippi Scale for Combat-Related Post-Traumatic Stress Disorder) and anxiety levels (Spilberger's State Trait Anxiety Inventory) were tested in 1994 and 1999.

Results: Patients with PTSD symptoms had significantly higher anxiety levels then patients without PTSD symptoms. The percentage of patients manifesting PTSD increased from 19% in 1994 to 41% in 1999. Over the same period, the anxiety levels decreased in the patients with PTSD.

Conclusion: Anxiety and PTSD seem to share common etiologic grounds. Nevertheless, staying in the same homogenous group for a substantial period of time, in combination with inadequate social support and deficient psychological care, may contribute to the development of the PTSD symptomatology.
