The trajectory of bombing-related posttraumatic stress disorder among Iraqi civilians: Shattered world assumptions and altered self-capacities as mediators; attachment and crisis support as moderators

摘要

This study examined the impact of bombing on posttraumatic stress disorder (PTSD) and psychiatric co-morbidity over time, whether this relationship was mediated by shattered world assumptions and altered self-capacities, and whether the mediational effects were moderated by attachment style and crisis support among Iraqi civilians. One hundred and fifty-nine Iraqi civilians completed questionnaires measuring the aforementioned psychological constructs. Bombing exposure was associated with PTSD and psychiatric co-morbidity over time; 87% and 77% met the criteria for PTSD at baseline and five months respectively. Shattered world assumptions and altered self-capacities mediated the impact of bombing exposure on PTSD and psychiatric co-morbidity over time. The mediational effect for shattered world assumptions was not moderated by attachment style and crisis support. However, the mediational effect for altered self-capacities was moderated by fearful attachment and a medium level of crisis support. To conclude, following bombing, Iraqi civilians' assumptions about the world and others can change. These changes can have long term effects on psychological distress but are not influenced by childhood attachment experiences or the amount of crisis support received. Bombing can also change civilians' perceptions of internal capacities like emotional regulation, particularly those with fearful attachment who rely on crisis support to some extent.
