Abstract

Objective

To measure the incidence and impact of posttraumatic stress disorder (PTSD) in a cohort of 70 subjects with severe acute respiratory syndrome (SARS).

Methods

Clinical assessments of PTSD were conducted at 2, 7, 10, 20 and 46 months after discharge from medical hospitalization for treatment of SARS. Diagnoses of PTSD were established by a trained psychiatrist using the Chinese Classification of Mental Disorders (CCMD-III) and Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) criteria. To study the impact of PTSD, we used the Impact of Event Scale (IES), Zung Self-Rating Anxiety Scale (SAS), Zung Self-Rating Depression Scale (SDS), Symptom Checklist 90 (SCL-90), Short Form-36 (SF-36 Health Survey) and Social Disability Screening Schedule (SDSS).

Results

Of the 68 subjects who finished at least two follow-up interviews, 30 developed PTSD over the study period (44.1%). Scores on IES, SAS, SDS and SCL-90 (P<.0001) were higher, and functional impairment as measured by SF-36 (P<.0001) and SDSS was more severe (P=.0073) for subjects with PTSD.

Conclusion

PTSD occurs in a significant percentage of subjects who recover from SARS, and the occurrence of PTSD predicts persistent psychological distress and diminished social functioning in the 4 years after SARS treatment.
