Surveys from 50 multiracial Japanese European Americans supported the endorsement of multiple simultaneous racial/ethnic identities and a differentiated multiracial identity. Multiracial Japanese European American participants were recruited through Internet postings on Web sites, advertising in newsletters, and flyers sent to local and national college and community organizations related to multiracial and Asian American issues. Initial recruitment notices requested individuals to e-mail or call toll-free to obtain a survey. Additional recruitment occurred through snowballing: Professional colleagues or acquaintances of the researchers distributed questionnaires to students or acquaintances; in addition, participants who called or e-mailed sometimes requested additional questionnaires to distribute to potential participants. These multiple recruitment methods resulted in a national sample that included college students and community members. The survey was constructed from thematic data analysis of qualitative interviews exploring racial/ethnic identity, related experiences, and influences. Interviews were conducted with three female and two male Japanese European American interviewees recruited in the San Francisco Bay area. Participants in the interviews ranged in age from 26 to 49 years, with a mean age of 33.8 years; all were college graduates and currently pursuing graduate degrees. The full survey consisted of 108 questions that address current identifications by self and others; associated experiences; perceptions of and experiences in relation to different racial and ethnic groups; developmental influences on identity; and family, community, and educational influences on identification. Implications for research and therapy are discussed. This study suggests that therapists working with multiracial clients who present with difficulties related to racial/ethnic identities should be aware of the normative experience of multiple identities and avoid contributing to pressure to choose only one identity or membership.
