Background: Post-traumatic stress disorder (PTSD) can occur after life-threatening events, including illness, but correlates of PTSD after stroke or transient ischemic attack (TIA) have not been well described. Methods: We measured the prevalence of stroke-induced PTSD with the PTSD Checklist Specific for stroke (PCL-S) in adults who had a stroke or TIA within 5 years. A PCL-S score of 50 or more indicated likely PTSD. We tested for potential predictors of stroke-associated PTSD, including demographics, stroke history, disability, medical comorbidities, depression, and emotional support and then examined the association between poststroke PTSD and measures of physical and mental health. Results: Of 535 participants, 95 (18%) had a PCL-S score of 50 or more; the mean score was 35.4 +/- 13.7 (range 17-80 of 85). In logistic regression analysis, low income (odds ratio [OR] 1.98, 95% confidence interval [CI] 1.01-3.61), recurrent stroke or TIA (OR 1.86, 1.10-3.16), more disability (OR 1.79, 1.43-2.23), and increased comorbidities (OR 1.90, 1.05-3.45) were independently associated with PTSD. Older age (OR .93, .90-.95), marriage or partnership (OR .52, .28-.98), and having emotional support (OR .25, .11-.54) were protective against developing PTSD. Participants with likely PTSD had worse physical and mental health. Conclusions: In this racially and ethnically diverse cohort of stroke and TIA survivors, stroke-induced PTSD was associated with younger age, recurrent strokes, greater disability, and comorbidities. PTSD was associated with a substantially increased physical, mental, and quality of life burden in this already vulnerable population. Having social support was protective, suggesting a potential target for intervention.
