RESUMO
The 'Stroke Complications after Traumatic Experiences and Stress' (SATURN) study was designed to investigate the effects of a prior traumatic event on PTSD symptoms triggered by a subsequent stroke. First-ever ischemic stroke patients were surveyed 9-13 months after hospitalization at the Charité University Medical Center. Stroke-induced PTSD symptoms were measured using the Impact of Event Scale-revised (IES-R). Prior traumatization together with past PTSD symptoms was assessed retrospectively with the Brief Trauma Questionnaire (BTQ) and the 7-item Short Screening Scale for PTSD. Depressive symptoms were assessed with the Beck Depression Inventory (BDI-II). The Short Form (SF)-36 was used to evaluate physical and mental health outcomes. We received 258 responses from 636 eligible patients (~41%). Based on respondents' scores on the IES-R, the prevalence of probable PTSD due to the stroke event was 11% in our sample. Female sex and younger age were associated with more severe PTSD symptoms. Psychological endpoints did not differ between patients who denied prior trauma exposure and those who reported earlier trauma exposure but denied subsequent PTSD symptoms. However, a history of trauma exposure in tandem with endorsing subsequent PTSD symptoms was linked with significantly increased post-stroke PTSD and depressive symptoms together with decreased psychological well-being. Self-reported physical health did not differ across groups. Younger age, being a woman, and having developed PTSD symptoms in the aftermath of a prior trauma were associated with adverse psychological outcomes after stroke.
