ABSTRACT
OBJECTIVE: The authors sought to assess the severity and longitudinal course of posttraumatic stress, anxiety, and depressive reactions among two groups of adults differentially exposed to severe and mild earthquake trauma and a third group exposed to severe violence. They also examined interrelationships among these reactions and predictors of outcome and compared posttraumatic stress disorder (PTSD) symptom category profile and course between those exposed to earthquake and those exposed to violence. METHOD: Seventy-eight non-treatment-seeking subjects were assessed with self-report instruments approximately 1.5 and 4.5 years after the 1988 Spitak earthquake in Armenia and the 1988 pogroms against Armenians in Azerbaijan. RESULTS: The two groups that had been exposed to severe trauma (earthquake or violence) had high initial and follow-up PTSD scores that did not remit over the 3-year interval. Overall, depressive symptoms subsided. Posttraumatic stress, anxiety, and depressive reactions were highly intercorrelated within and across both time intervals. No significant differences in PTSD severity, profile, or course were seen between subjects exposed to severe earthquake trauma versus those exposed to severe violence. CONCLUSIONS: After exposure to severe trauma, either an earthquake or violence, adults are at high risk of developing severe and chronic posttraumatic stress reactions that are associated with chronic anxiety and depressive reactions. Clinical evaluation and therapeutic intervention should include specific attention to these reactions. Early mental health intervention is recommended to prevent their chronicity.

OBJECTIVE: This study evaluated basal salivary cortisol, 3-methoxy-4-hydroxyphenylglycol (MHPG), and cortisol suppression following dexamethasone administration in adolescents exposed to two levels of earthquake-related trauma. METHOD: Five years after the 1988 earthquake, saliva samples were obtained from 37 adolescents from two cities in Armenia at different distances from the epicenter. Baseline saliva samples were obtained at 8:00 a.m., 4:00 p.m., and 11:00 p.m., following which 0.5 mg of dexamethasone was administered. Nine and 17 hours later, saliva samples were again obtained. Subjects were evaluated for posttraumatic stress and depressive reactions through use of self-report instruments. RESULTS: Significantly lower mean baseline 8:00 a.m. cortisol levels and greater day 24:00 p.m. cortisol suppression following dexamethasone were observed in the more symptomatic adolescents living in the city closer to the epicenter. Of the three symptom categories of posttraumatic stress disorder (PTSD), only intrusion (category B) symptoms were significantly correlated with basal morning cortisol levels and percent suppression by dexamethasone. The more highly exposed adolescents also exhibited a more rapid decline in MHPG levels over the course of day 1. CONCLUSIONS: The findings indicate that chronic posttraumatic stress reactions among adolescents exposed to catastrophic disaster are associated with hypothalamic-pituitary-adrenal (HPA) axis alterations. The findings are congruent with those previously described in adults with chronic PTSD. Persistent intrusion (category B) symptoms may constitute continued episodes of distress and evoke repeated physiological stress responses, which, over time, alter HPA axis function. The MHPG findings suggest that there may be diurnal changes associated with severity of posttraumatic stress symptoms.

One and a half years after the devastating earthquake in Armenia in 1988, 231 children from three cities at increasing distances from the epicentre were randomly screened in their schools to determine the frequency and severity of post-traumatic stress reactions, using the Children's Post-traumatic Stress Disorder Reaction Index (CPTSD-RI). A systematic clinical assessment of PTSD based on DSM-III-R criteria was also conducted on approximately half of this sample. A high CPTSD-RI score was strongly correlated with a clinical diagnosis of PTSD. A strong positive correlation was found between proximity to the epicentre and overall severity of post-traumatic stress reaction, as well as severity of core component symptoms of PTSD. High rates of chronic, severe post-traumatic stress reactions were found among children in the two most damaged cities, Spitak and Gumri. Analyses controlling for exposure revealed that girls reported more persistent fears than boys. These findings indicate that after catastrophic natural disaster, post-traumatic reactions in children may reach epidemic proportions, remain high for a prolonged period, and jeopardise the well-being of the child population of a large region. Systematic screening of children for PTSD can provide critical information for a rational public mental health programme after such a disaster.
