Research into intimate partner violence among Asian-American and immigrant populations is complex because of the multifaceted issues that emerge due to: (1) their marginalized position and vulnerability; and (2) the subject matter being considered sensitive. The author argues that a discussion of ethics is inherent to any discussion about cultural competence and social scientific research. A key ethical concern is the underlying issues of power with the researcher-subject dyad. Researchers are cautioned to be particularly sensitive regarding: (1) the subjects’ level of autonomy within the research-subject relationship; (2) the language barrier that may interfere with informed consent; (3) the limits to confidentiality and the consequences for subjects’ physical welfare; and (4) the minimization of subject distress and the assurance of subject safety. Since it is unrealistic to assume researchers can become familiar with the array of specific logistical and cultural nuances pertaining to the ethnic minority group under study, it is suggested that the research process be viewed as a collaboration effort with community leaders and cultural experts. In outlining these ethical concerns, the author reviews Western biomedical ethics from a sociocultural context, which holds individual rights as sacred and based on four ethical principles: autonomy, beneficence, nonmaleficence, and justice. The author also considers intimate partner violence within Asian-American and Asian immigrant families, which remains largely a hidden problem due to the taboo associated with disclosure. References
