Abstract

OBJECTIVES

To identify the incidence and factors impacting post-traumatic stress disorder (PTSD) at 6 months, 2 and 7 years following the 2005 Eyre Peninsula bushfires in South Australia.

METHODS

A questionnaire was used to assess symptoms.

DESIGN AND SETTING

A longitudinal follow-up study with responses collected from a self-report booklet.

PARTICIPANTS

179 respondents were present at 6 months post bushfires, with 103 and 87 participants at 2 and 7 years, respectively.

MAIN OUTCOME MEASURES

PTSD rates and its precipitating factors.

RESULTS

The proportion of PTSD cases at times 1, 2 and 3 were 13.4% (24/179), 10.7% (11/103), and 4.8% (4/87), respectively. At 6 months, terrifying experience of fire reduced odds of developing PTSD (Odds Ratio [OR]: 0.45; 95% CI 0.21-0.96) while relocation increased odds (OR: 2.93; 95% CI 1.06-8.08). At 2 years, relocation (OR: 6.81; 95% CI 1.07-43.41) was a positive predictor. At 7 years, personal loss from the fires (OR: 2.82; 95% CI 1.17-6.77) positively predicted PTSD.

CONCLUSION

PTSD rates declined over time. Relocation may be a proxy measure of high levels of emotional trauma. Those most traumatised probably decided to relocate, and hence, relocation should be considered a trigger for PTSD in the aftermath of bushfire.

摘要

目的

确定2005年南澳大利亚艾尔半岛丛林大火发生后6个月、2年和7年时创伤后应激障碍（PTSD）的发病率及影响因素。

方法

采用问卷调查评估症状。

设计与背景

一项纵向随访研究，通过自填式手册收集回复。

参与者

丛林大火发生后6个月时有179名受访者，2年和7年时分别有103名和87名参与者。

主要观察指标

PTSD发病率及其诱发因素。

结果

第1、2和3阶段PTSD病例的比例分别为13.4%（24/179）、10.7%（11/103）和4.8%（4/87）。在6个月时，可怕的火灾经历降低了患PTSD的几率（优势比[OR]：0.45；95%置信区间0.21 - 0.96），而搬迁则增加了几率（OR：2.93；95%置信区间1.06 - 8.08）。在2年时，搬迁（OR：6.81；95%置信区间1.07 - 43.41）是一个正向预测因素。在7年时，火灾造成的个人损失（OR：2.82；95%置信区间1.17 - 6.77）正向预测PTSD。
