title: Factors associated with willingness to participate in biospecimen research among Chinese Americans.
abstract: A paucity of information exists on the recruitment of Asian Americans for biospecimen research. Although studies show that Chinese Americans are at high risk for hepatitis B virus (HBV) infection, little is known about their willingness to participate in HBV-related biospecimen research and how knowledge, attitudes, and cultural factors impact their willingness to participate. The study was guided by Community-Based Participatory Research principles. Data were derived from an assessment study on HBV-related biospecimen research participation among Chinese Americans in the Philadelphia region. The assessment was conducted with 415 Chinese Americans recruited from eight Chinese community-based organizations. Cultural beliefs, knowledge, and attitudes toward biospecimen research were examined for associations with their willingness to participate in biospecimen banking research. Overall, 192 (46.3%) of 415 participants who completed the assessment indicated they were willing to participate if they were invited to donate blood to be frozen and stored for future HBV biospecimen studies. Cultural variables significant in bivariate analysis included collectivism, knowledge about biospecimen research, and Yin-Yang beliefs. Fatalism and individualism were not associated with participation willingness. In multivariate analysis, age, health care attitudes, and trust were significantly associated with willingness to participate in biospecimen banking research. Asian American communities have little knowledge of biospecimen banking and will benefit from educational campaigns that emphasize collective benefits and attitudes towards and trust in the health care system. Understanding cultural factors is important for improving Chinese Americans' knowledge, awareness, and intentions of participation in biospecimen research. Similar efforts need to be undertaken to develop culturally appropriate educational intervention programs to increase participation in biospecimen research among other Asian American groups.
