The purpose of this study was to identify the beliefs about physical activity held by Chinese immigrant older adults in Seattle and to compare them with the beliefs held by Chinese elderly in Taipei. Researchers conducted 2 focus groups of Chinese older adults to explore their behavioral beliefs, normative beliefs, and perceived control beliefs. The first group included 10 elderly recruited from the Chinese Information and Service Center in Seattle, Washington. The second group included 14 elderly adults recruited from a health center in Taipei, Taiwan. This study used a qualitative study design, and deductive content analysis was used for analyzing information gathered. The results showed that Chinese immigrant older adults in Seattle had positive attitudes toward physical activity and that, compared with the group in Taipei, the group in Seattle perceived more positive social and environmental supports. The factors influencing Chinese older adults' physical activity and behaviors both in Seattle and in Taipei are discussed.
