Post-traumatic stress disorder in children after the tsunami disaster in Thailand: a 5-year follow-up.

BACKGROUND: Children may suffer from post-traumatic stress disorder after disaster. There was a severe tsunami following an undersea earthquake off the Sumatra coast of Indonesia. There were 20,000 children in 6 southwestern provinces of Thailand who were possibly affected. OBJECTIVE: To study the prevalence of post-traumatic stress disorder (PTSD) in Thai students in the area affected by the December 26th, 2004 tsunami disaster, Thailand. MATERIAL AND METHOD: One thousand six hundred and fifteen surviving students from two schools in Takua Pa district located in Phang-nga Province, Thailand participated in this longitudinal study. Screening was done by using Pediatric Symptom Checklists part II (PSC-II), Childhood Depressive Intervention (CDI) and the Revised Child Impact of Events Scales (CRIES 8). PTSD was diagnosed by child and adolescent psychiatrists by using criteria of DSM-IV. The intervention included psychological first aid, psycho-education, cognitive-behavioral therapy, medication in severe cases, group support for students, parents and teachers which was done, beginning at 10 days after the tsunami disaster. Data were analyzed by using SPSS version 12.0. RESULTS: The prevalence rates of PTSD in the students facing the tsunami disaster in the study group were 573, 46.1, 31.6, 7.6, 4.5, 3.9 and 2.7% at 6 weeks, 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after the disaster, respectively. Female to male ratio was 1.7: 1. The peak age was 9-10 years old. The top five on the list of symptoms in PTSD were distress with cue, intrusive thought, functioning impairment, startled response, terrified and hyper vigilance. Seven cases (3.1%) were diagnosed partial PTSD, still exhibited a wide range of PTSD symptoms but did not fulfill the DSM-IV diagnostic criteria. The top five on the list of symptoms in partial PTSD were avoiding thought/feelings, terrified, avoiding place/activities, distress with cue and startled response. CONCLUSION: The prevalence of PTSD among tsunami victims was 57.3% at 6 weeks after the disaster. It declined sharply at 2 years after the event. Despite receiving financial, rehabilitation and mental health support, 2.7% of the victims continued to suffer from PTSD 5 years after the disaster.
