13.    Are there special considerations required in cross-cultural research? Yes. Researchers engaged in cross-cultural research should give particular attention to the use of culturally appropriate assessment instruments and procedures, the language(s) used in the conduct of the research, and the language preference and language variability of the research participants. Researchers developing studies involving members of an unfamiliar racial, ethnic, cultural, linguistic, gender or sexuality group should develop a reasonable level of familiarity with, but would not be limited to, the language, behavior, social mores, customs and traditions of that group. A researcher should consider consulting social and behavioral scientists and others who are more knowledgeable of, and experienced with, the intended study group before constructing a protocol.
