Significant others (SOs), such as spouses and life partners, of patients who have survived subarachnoid hemorrhage (SAH) can experience psychiatric symptoms and psychosocial disability. The cause of such symptoms has not been established. Authors of the present study analyzed whether posttraumatic stress disorder (PTSD) subsequent to a loved one's SAH is a plausible explanation for these symptoms.
The authors examined a large representative sample of 86 patient/SO pairs 3.5 months postictus. All SOs were evaluated using a diagnostic PTSD measure, and coping skills were assessed. The cognitive, physical, and emotional status of patients was comprehensively examined.
Twenty-six percent of SOs met the diagnostic criteria for PTSD, which represents a 3-fold increase in the rate expected within the general population. To establish the cause of PTSD, a logistic regression was performed, and results of this test showed that the use of maladaptive coping strategies was the best predictor of the disorder. A patient's level of disability held no significant association with the development of PTSD in his or her SO.
The elevated incidence of PTSD in SOs helps to explain why these persons report concerning levels of psychiatric symptomatology and psychosocial disability. Greater attention must be given to an SO's adjustment to the experience of having a loved one suffer an SAH. This need is all the more pertinent given that SOs often act as informal caregivers and that PTSD could interfere with their ability to effectively minister. Because bad coping skills seem to be the main cause of PTSD, teaching SOs better strategies might prevent the disorder and any resulting psychosocial disability.
