Stress and Psychological Distress among SARS Survivors 1 Year after the Outbreak

Abstract

Objective: Our study examined the stress level and psychological distress of severe acute respiratory syndrome (SARS) survivors 1 year after the outbreak. Method: During the SARS outbreak in 2003, we used the 10-item Perceived Stress Scale (PSS-10) to assess SARS survivors treated in 2 major hospitals (non–health care workers, n = 49; health care workers, n = 30). We invited SARS survivors from the same hospitals (non–health care workers, n = 63; health care workers, n = 33) to complete the PSS-10 again in 2004. At that time, they were also asked to complete the General Health Questionnaire (GHQ-12) and measures of depression, anxiety, and posttraumatic symptoms. PSS-10 scores were also obtained from matched community control subjects during the outbreak ( n = 145) and again in 2004 ( n = 112). Results: SARS survivors had higher stress levels during the outbreak, compared with control subjects (PSS-10 scores =19.8 and 17.9, respectively; P < 0.01), and this persisted 1 year later (PSS-10 scores =19.9 and 17.3, respectively; P < 0.01) without signs of decrease. In 2004, SARS survivors also showed worrying levels of depression, anxiety, and posttraumatic symptoms. An alarming proportion (64%) scored above the GHQ-12 cut-off that suggests psychiatric morbidity. During the outbreak, health care worker SARS survivors had stress levels similar to those of non–health care workers, but health care workers showed significantly higher stress levels in 2004 (PSS-10 score = 22.8, compared with PSS-10 score = 18.4; P < 0.05) and had higher depression, anxiety, posttraumatic symptoms, and GHQ-12 scores. Conclusions: One year after the outbreak, SARS survivors still had elevated stress levels and worrying levels of psychological distress. The situation of health care worker SARS survivors is particularly worrying. The long-term psychological implications of infectious diseases should not be ignored. Mental health services could play an important role in rehabilitation.
