The current study is designed to increase knowledge of the effects of relocation and its association with longer‐term psychological symptoms following disaster. Following clinical observations and in discussions held with school officials expressing concerns about relocated students, it was hypothesized that students who relocated to a different city following Hurricane Katrina in 2005 would have more symptoms of posttraumatic stress compared to students who returned to New Orleans. The effect of Hurricane Katrina relocation was assessed on a sample of child and adolescent survivors in 5th through 12th grades (N = 795). Students with Orleans Parish zip codes prior to Hurricane Katrina were categorized into relocation groupings: (a) relocated to Baton Rouge, (b) returned to prior zip code, and (c) moved to a different zip code within Orleans Parish. Overall results revealed more trauma symptoms for relocated students. Results also revealed that younger relocated students had fewer symptoms compared to older students. The opposite was found for students who returned to their same zip code, with older students having fewer symptoms. This study supports the need for school‐based services not only in disaster areas, but also in schools where survivors tend to migrate. 標題：卡蒂尼娜颶風後兒童及青少年倖存者長期遷移的效果。 撮要：本研究旨在認識遷移的效果和對災後長期心理症狀的關連。我們先作臨床觀察，和學校員工商討有關遷移學生的憂慮，然後假設在2005年卡蒂尼娜颶風後遷移到其他地方城市的學生比較重回新奧爾良的學生會有更多創傷後壓力症症狀。本研究樣本為第五班至十二班的兒童及青少年倖存者(N=795)。利用災前他們在奧爾良的郵遞區號分為不同的遷移組別：(a)遷至Baton Rouge；(b)回到本來郵遞區號的住處；和(c)搬至奧爾良不同郵遞區號的地方。總括而言，遷移了的學生有更多創傷症狀，亦顯示年青的遷移學生有較少症狀(對比年長學生)。但重回舊郵遞區號的學生，年長學生卻有較少症狀。本文支持校內服務不只在災難地區，亦應在倖存者遷移的學校提供。 标题：卡蒂尼娜飓风后儿童及青少年幸存者长期迁移的效果。 撮要：本研究旨在认识迁移的效果和对灾后长期心理症状的关连。我们先作临床观察，和学校员工商讨有关迁移学生的忧虑，然后假设在2005年卡蒂尼娜飓风后迁移到其他地方城市的学生比较重回新奥尔良的学生会有更多创伤后压力症症状。本研究样本为第五班至十二班的儿童及青少年幸存者(N=795)。利用灾前他们在奥尔良的邮政编码分为不同的迁移组别：(a)迁至Baton Rouge；(b)回到本来邮政编码的住处；和(c)搬至奥尔良不同邮政编码的地方。总括而言，迁移了的学生有更多创伤症状，亦显示年青的迁移学生有较少症状(对比年长学生)。但重回旧邮政编码的学生，年长学生却有较少症状。本文支持校内服务不只在灾难地区，亦应在幸存者迁移的学校提供。
