Previous research has documented that individuals exposed to more stressors during disasters and their immediate aftermath (immediate stressors) are at risk of experiencing longer-term postdisaster stressors. Longer-term stressors, in turn, have been found to play a key role in shaping postdisaster psychological functioning. Few studies have simultaneously explored the links from immediate to longer-term stressors, and from longer-term stressors to psychological functioning, however. Additionally, studies have inadequately explored whether postdisaster psychological symptoms influence longer-term stressors. In the current study, we aimed to fill these gaps. Participants (N = 448) were from population-based study of Hurricane Ike survivors and completed assessments 2–5 months (Wave 1), 5–9 months (Wave 2) and 14–18 months (Wave 3) postdisaster. Through path analysis, we found that immediate stressors, assessed at Wave 1, were positively associated with Wave 2 and Wave 3 stressors, which in turn were positively associated with Wave 2 and Wave 3 posttraumatic stress and depressive symptoms. Wave 2 posttraumatic stress symptoms were positively associated with Wave 3 stressors, and Wave 1 depressive symptoms were positively associated with Wave 2 stressors. The findings suggest that policies and interventions can reduce the impact of disasters on mental health by preventing and alleviating both immediate and longer-term postdisaster stressors.

撮要：昔日研究指出災難中經歷更多壓力和即時後果(即時壓力) 會有更高風險經歷災難後長期壓力，長期壓力又塑造災難後心理功能。只有少量研究同時探索即時至長期壓力源的關連，和長期壓力源至心理功能的連結，亦未有研究充分探求災難後心理症狀有否影響長期壓力源。本研究意圖填補上述空白。從颶風艾克倖存者人口研究中選取樣本(N = 448)，而在風暴後2–5個月(浪1)、5–9個月(浪2)和14–18個月(浪3)進行評估。利用路徑分析，在浪1的即時壓力源與浪2及浪3壓力源呈正相連，然後再順序地與浪2和浪3創傷後壓力和抑鬱症狀呈正相連。浪2創傷後壓力症與浪3壓力源呈正相關，而浪1抑鬱症狀與浪2壓力源呈正關連。結果建議：預防和減輕即時和長期災難後壓力源的相關政策及介入服務能減少災難對精神健康的衝擊。
