title: The SARS (Severe Acute Respiratory Syndrome) pandemic in Hong Kong: effects on the subjective wellbeing of elderly and younger people.
abstract: OBJECTIVE
  This study examined the impact of the Severe Acute Respiratory Syndrome (SARS) outbreak in Hong Kong in 2003, on the subjective wellbeing (SWB) of elderly people and a younger comparative sample. The Personal Wellbeing Index (PWI), a contemporary instrument employed to measure SWB, was also examined for its psychometric performance to substantiate its use.
  
  
  METHODS
  A total of 302 older adults (age 65 + years) and 158 younger adults (age 35-46 years) were recruited from different districts. Data were collected by individual face-to-face interviews.
  
  
  RESULTS
  While elderly people living in severely infected districts showed significantly lower levels of SWB, these levels and those of the younger sample were found to remain within the normative range. A major mitigating factor was an increased sense of community-connectedness. Other characteristics linked to low wellbeing levels included chronic illness, female gender, low education and unemployment. The living districts, characterized by varying extents of infection, had stronger associations with SWB than participants' age. The PWI demonstrated good psychometric performance and also more robustness with elderly people, including its sensitivity to the sense of population threat.
  
  
  CONCLUSIONS
  Psychological resilience was identified among both the elderly and younger age-groups in Hong Kong during the SARS pandemic. The PWI is verified as a suitable instrument for SWB measurements.
