World health organization (WHO) defines health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Quality of life is defined as the individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals. Posttraumatic Stress Disorder (PTSD) is a psychiatric disorder that can develop in people who are actively or passively exposed to life-threatening experiences and it is characterized by symptoms such as intrusive memories on a traumatic event, followed by hyperarousal and avoidance, and exclusion. While PTSD is primarily associated with mental health, it is not possible to exclude the impact of this disorder on physical health. Previous research has shown poorer quality of life in people suffering from this disorder, with frequent difficulties in psychosocial functioning. The main aim of this study was to establish the correlation between the quality of life and the intensity of PTSD symptom among the Croatian War of Independence veterans exposed to war psychotraumatization. Additional goals were to examine the relationship between the intensity of PTSD symptom with a particular domain of functioning: mobility, self-care, usual activities, pain/ discomfort and anxiety/depression. A study was performed on 200 patients who were treated at the Clinical Hospital in Rijeka on Psychiatric Clinic using the EQ-5D-5L instrument. A statistically significant difference was found in three of the five dimensions of functioning, with differences related to daily activity, pain/discomfort and depression/anxiety. According to VAS results, patients with higher intensity symptoms of PTSD evaluate their health worse than those with mild and moderate intensity symptoms.
