方法:采用问卷测量的方法,在泥石流灾难发生后3 个月、15 个月和27 个月时,以班级为单位,对甘肃省甘南藏族自治州舟曲县的在校学生进行心理健康调查。
采用自编背景资料调查问卷、加州大学创伤后应激障碍反应指数修改版儿童版量表 (UCLA PTSD RI Child Version)。 
结果: (1)泥石流3 个月、15 个月、27 个月后的闯入症状检出率均高于回避症状和高警觉症状;亚PTSD 中,闯入和高警觉症状的共同检出情况较高;各阶段PTSD 总体检出情况呈下降趋势,分别为:9.90%、9.39%、5.87%。 (2)潜类别增长分析 (LCGA)表明,泥石流灾后当地儿童创伤后应激障碍症状存在五类发展轨迹,按照各轨迹在人群中所占比例由高到低依次为:正常应激 (40.97%)、心理韧性(29.85%)、心理恢复(21.70%)、延迟受损(5.32%)、持续受损(2.16%)。
Other AbstractObjective: To explore the development trajectories of PTSD symptoms of children who exposed debris flood. Method:  Investigations were respectively  implemented 3, 15, 27 months after the debris flood to assess mental health of students in ZhouQu county GanSu province in China. More than 3000 students were assessed for each investigation with the UCLA PTSD INDEX FOR DSM-IV (Revision 1 Child Version) and self-designed questionnaire for background information. Results: (1) The positive rate of intrusion symptom were relative higher than avoidance and hyper-arousal across the three measurements, and the comorbidity rate of intrusion and hyper-arousal was higher in terms of the sub-PTSD prevalence, also the prevalence rates of PTSD for each measurement were 9.90%、9.39%、5.87%  respectively;  (2) LCGA shows that five trajectories were found, including normal (40.97%), resilience (29.85%), recovery(21.70%),  delayed(5.32%), chronic(2.16%);  (3)  the distribution difference of children with different gender, grade, trauma exposure in  some of  the trajectories was significant. Conclusion: Children who exposed in heavy natural disaster were the high risk group of mental health diseases, and the recovery process was also different in terms of individual difference; girls, high grade students and high trauma exposure children need more attention during the psychological assistance.
