Abstract
This study investigated the trajectory of traumatic stress symptoms in the aftermath of the 2004 Southeast Asian earthquake-tsunami. A total of 265 adult Thai survivors were assessed at 2 weeks and 6 months following the earthquake-tsunami. The percentages of survivors reporting traumatic stress symptoms were 22% at 2 weeks and 30% at 6 months postdisaster. Four trajectories of traumatic stress symptoms were identified: 12% of survivors presented with chronic stress symptoms, 18% had a delayed onset, 10% showed improvement, and the remaining 60% maintained a stable emotional equilibrium. Among survivors, the chronic group was the oldest, the delayed group reported the lowest level of perceived government support, and the resilient group experienced the fewest postdisaster psychiatric symptoms. Results pointed to the need to broaden the conceptualization of postdisaster stress responding as well as to establish disaster psychiatry and related mental health activities in the region.
