The relationship between military combat and postdeployment family functioning difficulties has been frequently investigated in the literature, as has the relationship between types of coping and posttraumatic stress disorder (PTSD). Few studies, however, have examined these variables together, and no studies of which we are aware have examined the effect of coping on family functioning after combat exposure. This study examined coping style measured immediately after return from deployment, and PTSD symptoms and family functioning 18–24 months after return from deployment in a sample of Operation Desert Shield/Storm veterans (N = 2,949). Structural equation models suggested that the relationships between distinct coping styles on family functioning were differentially mediated by postdeployment PTSD symptoms. Results are consistent with full mediation for avoidant coping (βdirect = −.09, p = .07; βindirect = −.17, p < .001) and partial mediation for approach coping (βdirect = .16, p < .001; βindirect = .09, p < .001). Results suggest that the strategies used to cope with a combat stress event may impact both PTSD and family functioning outcomes, and highlight the potential utility of pre‐ and postdeployment coping skills training. 標題：沙漠屏障/風暴行動後退役軍的應對策略和PTSD對家庭功能的影響 撮要：武裝戰鬥和退役後家庭功能障礙的關係，在文獻中多有研究，而應對策略和創傷後壓力症(PTSD)的關係亦有不少論述。但少有一併研究上述因素，亦未有研究戰後應對在家庭功能方面的影響。本文樣本為沙漠屏障/風暴行動(ODS)的退役軍人(N = 2,949)，研究他們退役後的即時應對策略，和退役後18–24個月的PTSD症狀和家庭功能。結構方程式模型顯示不同應對策略與家庭功能之間的關係都由退役後PTSD症狀差異作調節。結果指出迴避應對一致地全面調節(β直接 = ‐.09, p = .07；β非直接 = ‐.17, p<.001)，而接觸應對則局部調節(β直接 = .16, p<.001；β間接 = .09, p<.001)。結果亦顯示應對戰鬥壓力事件的各種策略可能影響PTSD和家庭功能結果，亦突顯退役前後應對技巧訓練的可能效用。 标题：沙漠屏障/风暴行动后退役军的应对策略和PTSD对家庭功能的影响 撮要：武装战斗和退役后家庭功能障碍的关系，在文献中多有研究，而应对策略和创伤后压力症(PTSD)的关系亦有不少论述。但少有一并研究上述因素，亦未有研究战后应对在家庭功能方面的影响。本文样本为沙漠屏障/风暴行动(ODS)的退役军人(N = 2,949)，研究他们退役后的实时应对策略，和退役后18–24个月的PTSD症状和家庭功能。结构方程式模型显示不同应对策略与家庭功能之间的关系都由退役后PTSD症状差异作调节。结果指出回避应对一致地全面调节(β直接 = ‐.09, p = .07；β非直接 = ‐.17, p<.001)，而接触应对则局部调节(β直接 = .16, p<.001；β间接 = .09,p<.001)。结果亦显示应对战斗压力事件的各种策略可能影响PTSD和家庭功能结果，亦突显退役前后应对技巧训练的可能效用。
