Objective:

Japanese-Americans are the sixth largest Asian ethnicity in the United States. They represent a highly heterogeneous population due to their history of immigration dating back to the late 19th century. In comparison to the total Japanese-American population, there are very few neuropsychologists of Japanese descent who are familiar with the culture. The Asian Neuropsychological Association lists 16 licensed members of Japanese descent, and only 7 practice outside of Hawaii or California. These numbers suggest that unless non-Japanese neuropsychologists are knowledgeable of the culture, test translations, and appropriate norms, it would be challenging for many Japanese-Americans to receive culturally and linguistically competent neuropsychological services. The aim of the present study is to provide guidance for conducting neuropsychological assessments with Japanese-Americans with the goal of facilitating competent culturally-informed services to this population.

Participants and Methods:

Pertinent facets of Japanese culture as identified in the ECLECTIC framework and demographics of the U.S. Japanese-American population, and the available literature on neuropsychological tests that are translated into Japanese and normed with Japanese samples, was reviewed by authors with knowledge of Japanese language and culture. Literature published in both English and Japanese were included for review.

Results:

Psychological testing is a Western technology fraught with the behavioral expectations and values of the culture in which it was developed. Thus, these tests may be biased against persons coming from cultures that differ from the West. Recommendations for providing neuropsychological services to Japanese-Americans are presented with an aim of maximizing test fairness by addressing the following issues: comfort with the testing situation, test biases, accessibility, and validity. Given the emphasis on education, Japanese-Americans should be familiar and comfortable with cognitive testing, although they may experience undue pressure to perform well to avoid shame. Japanese-Americans may experience discomfort disclosing personal information during the interview, particularly if the evaluation is perceived to be psychiatric in nature, as there is a strong stigma associated with mental illness that could bring shame to the family. Japanese communication styles are indirect in nature, where the message is implied and what is “not said” is just as important as what is directly conveyed. Accessibility issues will primarily impact first generation Japanese-Americans who are native Japanese speakers. Another characteristic that may impact responding is hesitancy for guessing when unsure. Recommendations for providing culturally competent neuropsychological assessment given these considerations will be presented and expanded upon in detail. Finally, an online database of translated and normed neuropsychological tests by cognitive domain has been created and will be presented.

Conclusions:

Providing neuropsychological services to Japanese-Americans can be challenging as Japanese culture is significantly different from western culture. In addition, Japanese-Americans are heterogenous with salient issues of English proficiency and acculturation. Information to individualize a conceptual understanding of Japanese-Americans, translated and normed tests, and recommendations to maximize fairness in testing are presented to assist clinical neuropsychologists provide competent services to Japanese-Americans.
