Background and Purpose: To explore the perception and fear of SARS among aboriginal residents in Taipei and in other cities in Taiwan. Methods: From June 8 to June 10, 2003, a telephone survey was conducted using nation-wide stratified random sampling. Data were collected using a computer-assisted telephone interview system. A total of 1,000 aboriginal respondents aged 18 or above, which included 507 Taipei City residents and 493 residents of other cities in Taiwan, were recruited to this survey. Results: There was a significant difference regarding the perception and fear of the SARS epidemic between Taipei City respondents and respondents from other cities. According to multiple logistic regression analysis, the following factors were significantly associated with fear of the SARS epidemic: aged 60 or above (OR=1.89; 95%CI=1.07-3.35), being female (OR=1.53; 95%CI=1.14-2.05), education level lower than senior high school (OR=1.87; 95%CI=1.39-2.53), perceiving SARS to be a severe disease (OR=5.17; 95%CI=3.36-7.97), daily life affected by the epidemic (OR=2.09; 95%CI=1.58-2.77) and perceiving one might contract SARS personally (OR=1.46; 95%CI=1.03-2.09). Conclusion: Demographic factors, the perceived threat of SARS and the impact of SARS on one's daily life were significantly correlated with fear of the SARS epidemic. Residential area was not a significant correlate with fear of the SARS epidemic.
